Suggested March 2024 How To Insert Ads In Between Content In WordPress, Without Any Plugin
Note: This method requires some meddling with the code. If you are not comfortable dealing with the code, don’t attempt it. You might also want to create a staging site of your blog and test this method on the staging site first before making it live.
Here is the method:
1. In your theme folder, open the functions.php file with a text editor.add_filter
Remember to change the “insert_ad_code_here” string to the actual ad code. Also, if there is any instance of single quote (‘) in your ad code, you have to add a before it. For example, if your ad code is something like:
What we are doing with this function is to take the content for each post and break it up into each paragraph. We then detect whether the third paragraph exists. If yes, we insert the ad code to the end of the paragraph. Lastly, we insert back the starting paragraph tag to each section and glue them back into a complete article.
Things you can change here include:
1. The paragraph to insert the ad tag. The default in the above code is the third paragraph. You can change to the second paragraph by changing all instances of $content_block to $content_block.
Note: The count of the array starts from 0, so $content_block means the third paragraph instead of the second.
3. The ad code. You don’t necessarily have to insert ad in-between the content. You can insert newsletter subscription form or any other stuff that you deem appropriate for your site.
Lastly, don’t forget to save the file and upload it to the server. As I mentioned earlier, it is best to test this on a staging site first before making it live.

You're reading How To Insert Ads In Between Content In WordPress, Without Any Plugin
The United States government’s National Vulnerability Database published a notification of a vulnerability discovered in the official WordPress Gutenberg plugin. But according to the person who found it, WordPress is said to have not acknowledged it’s a vulnerability.Stored Cross-Site Scripting (XSS) Vulnerability
XSS is a type of vulnerability that happens when someone can upload something like a script that wouldn’t ordinarily be allowed through a form or other method.
Most forms and other website inputs will validate that what’s being updated is expected and will filter out dangerous files.
An example is a form for uploading an image that fails to block an attacker from uploading a malicious script.
According to the non-profit Open Web Application Security Project, an organization focused on helping improve software security, this is what can happen with a successful XSS attack:
“An attacker can use XSS to send a malicious script to an unsuspecting user.
The end user’s browser has no way to know that the script should not be trusted, and will execute the script.
Because it thinks the script came from a trusted source, the malicious script can access any cookies, session tokens, or other sensitive information retained by the browser and used with that site.
These scripts can even rewrite the content of the HTML page.”Common Vulnerabilities & Exposures – CVE
An organization named CVE serves as a way for documenting vulnerabilities and publicizing the discoveries to the public.
The organization, which the U.S. Department of Homeland Security supports, examines discoveries of vulnerabilities and, if accepted, will assign the vulnerability a CVE number that serves as the identification number of that specific vulnerability.Discovery Of Vulnerability In Gutenberg
Security research discovered what was believed to be a vulnerability. The discovery was submitted to the CVE, and the discovery was approved and assigned a CVE ID number, making the discovery an official vulnerability.
The XSS vulnerability was given the ID number CVE-2024-33994.
The vulnerability report that was published on the CVE site contains this description:
“The Gutenberg plugin through 13.7.3 for WordPress allows stored XSS by the Contributor role via an SVG document to the “Insert from URL” feature.
NOTE: the XSS payload does not execute in the context of the WordPress instance’s domain; however, analogous attempts by low-privileged users to reference SVG documents are blocked by some similar products, and this behavioral difference might have security relevance to some WordPress site administrators.”
That means that someone with Contributor level privileges can cause a malicious file to be inserted into the website.
The way to do it is by inserting the image through a URL.
In Gutenberg, there are three ways to upload an image.
Choose an existing image from the WordPress Media Libary
Insert the image from a URL
That last method is where the vulnerability comes from because, according to the security researcher, one can upload an image with any extension file name to WordPress via a URL, which the upload feature does not allow.Is It Really A Vulnerability?
The researcher reported the vulnerability to WordPress. But according to the person who discovered it, WordPress didn’t acknowledge it as a vulnerability.
This is what the researcher wrote:
“I found a Stored Cross Site Scripting vulnerability in WordPress that got rejected and got labeled as Informative by the WordPress Team.
Today is the 45th day since I reported the vulnerability and yet the vulnerability is not patched as of writing this…”
So it seems that there is a question as to whether WordPress is right and the U.S. Government-supported CVE foundation is wrong (or vice-versa) about whether this is an XSS vulnerability.
The researcher insists that this is a real vulnerability and offers the CVE acceptance to validate that claim.
Furthermore, the researcher implies or suggests that the situation where the WordPress Gutenberg plugin allows uploading images via a URL might not be a good practice, noting that other companies do not allow that kind of uploading.
“If this is so, then tell me why… …companies like Google and Slack went to the extent of validating files that are loaded over an URL and rejecting the files if they’re found to be SVG!
…Google and Slack… don’t allow SVG files to load over an URL, which WordPress does!”What To Do?
WordPress hasn’t issued a fix for the vulnerability because they appear not to believe it is a vulnerability or one that presents a problem.
The official vulnerability report states that Gutenberg versions up to 13.7.3 contain the vulnerability.
But 13.7.3 is the most current version.
According to the official WordPress Gutenberg changelog that records all past changes and also publishes a description of future changes, there have been no fixes for this (alleged) vulnerability, and there are none planned.
So the question is whether or not there is something to fix.Citations U.S Government Vulnerability Database Report on the Vulnerability

Almost 5 star rating from more than 450 users.
Decent online support on forum.Installing and Activating Plugin
Finding All in One WP Security and Firewall Plugin
Once the plugin is installed and activated, it will create a menu item named “WP Security”. It has exhaustive options under different categories to protect your WordPress site.
MiscellaneousHow it Works? Precautions Before Enabling Any Options
Back up the whole site and the database.
As the plugin create entries in .htaccess file, backing up .htaccess file will help to restore the original settings.
Backup chúng tôi file.
Ensure you have FTP access to your hosting server. This will help to replace the files on emergency situation.
In summary, backup all your site content and enable only the security options you require. It is also recommended to verify the site’s accessibility after enabling firewall, user registration approval and other functions.Dashboard
The dashboard shows the strength meter indicating the security points of your site. The points are also shown in a breakdown chart indicating the weightage and distribution among options.
All in One WP Security Plugin Dashboard
There are options you can directly enable from the dashboard like maintenance mode, disable “admin” username, enable basic firewall, etc. We recommend NOT to enable any settings directly on the dashboard. Go to the individual settings page and enable only if it is required.
Below are the other details available on the dashboard tab:
The “Settings” tab offers backup and high level options like import/export all settings of the plugin.User Accounts
You have three options under user accounts section.
WP Username – here you can change the users with the name as “admin” to the desired name.
Display Name – check the list of users with the identical login and display names. Generally it is not recommended to have same display and login name to avoid hackers guessing the login name. This is not an important setting, since it is very easy to find the login name just by checking the post author.
Password – check the strength of your password and the meter will show you how much time it will take for a hacker to guess your password.User Login
User login section allows to control the logging of users to your site with the following settings:
AIOWPS Plugin User Login Settings
Login Lockdown – enable locking the user after certain number of unsuccessful attempts. This feature helps to stop all bots and send out the email notification when some user id is locked.
Failed Login Records – view the failed login attempts along with IP address and username.
Force Logout – enable this option to force logout all users after certain amount of time.
Account Activity Logs – view the list of last 50 user ids logged into your site.
Logged In Users – view the users currently logged into your site.User Registration
Under this section you can enable manual approval of users trying to register on your site and add captcha on default WordPress registration form. When you have ecommerce plugin for selling items on your site with user registration then enabling this feature will stop the actual customers as they will not be able to register automatically. Hence, do not enable this when you need to have automatic registration feature for any other purposes.Database Security
By default WordPress add the prefix “wp_” for all your database tables. Under this section you can change the default to random prefix which will increase the security of your site. Also you can schedule database backup on periodic interval and the backup on your email.
As far as we have checked, email function does not seem to work with this plugin. Hence, do not reply on this plugin for backup, there are many other dedicated backup solutions available for WordPress.Filesystem Security
You have the following four options under filesystem security section.
File Permissions – check all files and folders of your WordPress installation have necessary permission for read / write access and set the correct permission.
PHP File Editing – Disable the file editing from the dashboard. This option will remove the “Editor” menu to edit theme and plugin files directly from the dashboard.
WP File Access – Hackers can get more information about your WordPress installation using readme.html, chúng tôi and chúng tôi files. Enabling this option will disable direct access to these files.
Host System Logs – view error log file of your hosting server.WHOIS Lookup
Though WHOIS lookup is not a security feature, it enables to look out the details of the IP address or domain name within the admin dashboard.Blacklist Manager
Block IP addresses and user agents from accessing your site. The IP address can be entered using wild card like 195.*.*.* or 195.47.*.*. The user agent section will work only if it has words, in case if the user agent name has words with then the plugin does not seem to work.Firewall

Malware Scan – this is a paid add-on from third party site for scanning your site for malware detection.Maintenance
Enable maintenance mode when your site is taken down for maintenance and not accessible for users. Ideally there is no relation between maintenance mode and security unless your site is already affected and you want to keep the users away from accessing the content.Miscellaneous
Forbidding Author Info Via LinkUninstalling AIOWPS Plugin
The installation of this plugin will add backup directory and multiple MYSQL tables. Hence just uninstalling and deleting the plugin will NOT completely remove the plugin files from your site. The best way is to follow the below step by step process:
If you have any problem in accessing your site, then try restoring “.htaccess” and “wp-config.php” files from the backup before the plugin installation.
To develop the ideal app for your interest, you should have the proper knowledge of outsourcing mobile app development. Without the basic idea of the job, it is challenging to make the whole process smooth and hassle-free. Also, improper planning and research affect the result, thus negatively affecting your business.
However, a lot of common mistakes happen while outsourcing Mobile App Development. Following points will help you to take necessary precautions against the common mistakes and be wise while outsourcing Mobile Application Development for your business.
Lack of Research
Handing over your project without basic research about the developers may cost you more than you can imagine. To get optimal results, you have to choose the right company that suits your business needs and field of operation. Most of the companies available for the development of Android and iOS Applications are generally much efficient in a certain area. Choose the perfect partner that is able to relate to your vision.
To ensure eligibility and expertise of the companies, only online reviews and ratings are not enough. It is preferable to have a one on one interview with the developers. Enquire about the past projects undertaken by them and also get a clear picture of the team that will handle your project. Analysing the portfolio of the company always helps to get a better idea about its standard.
Another practical problem that comes into play while dealing with overseas development companies is the time zone difference. To avoid confusion and miscommunication, a rigid plan of action while keeping the time zone difference in mind is a must. It saves time and makes the whole process smooth with minimal clashes.
Lack of Planning
Planning is an essential part of every work. Before you hand over your project to the developers, extensive preparation is necessary. Who is the target audience, what will be the nature of services and products offered in the App, and all such relevant questions should be asked and answered while briefing the developers? A well-planned start ensures fewer chances of blunders later on.
Here are some probable points that will help you while planning the project:
You must have a clear objective for the application. Is it for boosting the loyalty of customers? Or to earn profits? It can very well be anything else, depending on your requirements. But sorting out the objective will help to form the structure of your app.
Decide what will be the nature of the application- Light app Version or Full feature product.
Make a proper budget estimation. Research, personal observation of the market, and discussion with fellow business partners are helping to get the idea of expenditure.
Make a deadline. Time is of great essence in the electronic market. People nowadays do not value clone apps. Thus timelines are equally important as quality and uniqueness.
Plan your app properly. Rushing to the developers with exemplary apps without a proper thought on all details may harm your interest in the end.
Lack of Communication
Enquire about previously undertaken similar projects and a client list of the company you plan to hire.
Study the response of employees to get a better idea about their professionalism, punctuality, and client satisfaction level.
Ensure there is no language barrier between you and the people involved in the task.
Get proper quotes of the budget for the type of App you desire.
Don’t forget to get the App tested. QA must be a part of every decent application. Discuss all related matters on this point with the company.
Lack of Budget Estimation
Planning on investments in outsourcing mobile app is essential. To ensure your satisfaction with the product and budget, a lot of knowledge and reasonability is required. For that, you have to be updated with all the facts and figures. It is good to explore the market to have a vague idea about the cost associated with app development.
Also, be very careful if the company offers a price too good to be true. Developing an app requires considerable effort, so companies focusing too much on affordability must be looked into thoroughly. Most of such cases end up in double expense when the product you get is not up to the expectations.Ending Note
Hiring the right experts for outsourcing your Application for Android and iOS platforms is not only beneficial for saving time and money but also it is significant to grow strong professional bonds. Define your priorities. Extensive research, proper planning on budget and timelines, and overall communication with the developers are the basic points that you have to keep in mind. With a suitable application for the business, your company is sure to progress in leaps and bounds.Shubham Sharma

Typing arrows in Microsoft Word does not have to be a chore. The application has provided multiple ways for users to accomplish this task, and we’re going to talk about how to insert an Arrow symbol in a Word document
Arrows are useful symbols for getting across information more efficiently than normal. This can save folks from typing long explanations when a simple arrow could suffice. Now, not everyone who uses Microsoft Word knows how to get this done, but believe us when we say that it doesn’t take much.How to insert an Arrow symbol in Word document
We’re going to show you how to insert an Arrow symbol in a Word via AutoCorrect, Shortcuts, and Symbols, so the following solutions should help:1] Use the AutoCorrect feature to insert an Arrow symbol in a Word
OK, so the first thing to do here is to try and use the AutoCorrect feature in Microsoft Word to type arrows. From our point of view, this is probably the fastest way to get the job done, well, when it works because there are rare times when it doesn’t.
So, let us look at how to do this right now:
Open the Microsoft Word application, then launch into a new document or an old one.
Move the mouse cursor to the location in the document where you want the arrow to appear.
Now, type the relevant combination of characters to create arrows.2] Create arrows in Word using Shortcuts
Let’s assume that AutoCorrect in its default form does not produce the type of arrows you need. You can always create a keyboard shortcut for Emoji in Office apps
This will help you add your own arrows that are not found by default in Microsoft Word.3] Type arrows using special characters in Word
For those who are wondering, the option is there to type arrows by the means of special characters. We do not view this as the ideal way, but there are some arrows from the section of the special character that cannot be brought to the forefront via AutoCorrect.
To learn how to get this done, please read our post on how to use Special Characters and Letters.4] How to type Arrows using equation mode in Word
Microsoft Word has an equation mode that makes it possible for users to use mathematical symbols. With this feature, users can insert arrows into their documents, so let us look at how to get this done.
Place the mouse cursor where you want the arrow to appear.
Next, you must press the Alt+= buttons to fire up the equation mode section.
You must now type a Backslash along with the relevant Math AutoCorrect shortcut.
Press the Space button and the shortcut text will transform into a specified arrow.
The following are examples of shortcuts you can use, along with what the arrows look like:
READ: 10 Default Microsoft Word settings you need to changeWhy can’t I use Arrow keys?
If you are having problems with using the arrow keys on your keyboard, then chances are it has something to do with the turning on of the scroll lock feature. Look for the scroll lock button on your computer keyboard to see if it is enabled. If this is the case, the button usually lights up, so disable it promptly.How many Arrow keys are there?
There are a maximum of eight arrow keys on a full-sized keyboard. On other types of keyboards, the number sits at four, and that’s fine since most computer users have no need for using eight arrows. But if that is not the case, then purchasing a new keyboard is always an option.
Introduction to Redis LPUSH
Redis LPUSH is used to insert the value specified in the head list and saved it in the key. If the key does not exist, it will create an empty list before performing the LPUSH operations. When a key contains a value that is not in the list, an error is returned. When we use LPUSH, we use the lrange method.

Web development, programming languages, Software testing & othersKey Takeaways
While using redis LPUSH command, it is possible to insert single as well as multiple values in a single command.
The list is used by Redis LPUSH to store the value. When inserting data into the redis key, we only used the key type as a list.What is Redis LPUSH?
The redis LPUSH command inserts the specified values that were heading in the value from the specified key. Using redis LPUSH, we can push multiple elements with a single command; we simply need to specify the arguments at the end of the command. Using redis LPUSH, elements will be inserted one by one, with the last element inserted at the top of the list, from leftmost to rightmost. If we insert x, y, and z elements, the output will have z in the first position, y in the second position, and x in the last position.
Syntax:LPUSH name_of_key val1 …. ValN
We can insert multiple elements of values into a single command by using LPUSH. LPUSH is the command used to insert the values in the syntax above. When using the LPUSH command, we must specify the key that will be used to store the element. When we use the LPUSH command, we only use one key. Value is the parameter that was used to define the value when using the redis LPUSH command.How to Use Redis LPUSH?
To use it we are using the ubuntu system for installing the redis server. While using the LPUSH we need to install redis server in our system.
Code:# apt install redis-server # redis-server --version
2. While using redis LPUSH now in this step we are login into the redis database by using the below command as follows. While executing the LPUSH command we need to login into redis cli by using the redis-cli command as follows.
3. Now in this step we are using the redis LPUSH method to insert the element. In the below example, we are using single key and single value to use the redis LPUSH command.
Code:LPUSH key_lpush "lpush_val1"
4. As we can see in the above example, we have used the key name as “key_lpush” and defined value as “lpush_val1”. Now in this step, we are adding a new value to the key name as key_lpush as follows.
Code:LPUSH key_ lpush " lpush_val2"
5. While adding the value into the key, now in this step we are using the LRANGE command to retrieve the element which we have defined. The below example shows how we can retrieve the value by using lrange which was defined in LPUSH as follows.
Code:LRANGE key_lpush 0 -1
Output:Redis LPUSH Command
The Redis LPUSH command is useful for inserting values because it allows us to insert single and multiple values in the same command. The command has been available since version 1.0.0. After the push operations are completed, the command will return the integer that was responding to the list length. The LPUSH command’s return value type is an integer. Basically, the LPUSH command adds a new element to the list’s left side.
Code:LPUSH redis_lpush "val1" LPUSH redis_lpush "val2" LRANGE redis_lpush 0 1
If we have already created a key with the type string, we cannot add the element by using LPUSH into the specified key. It will return the error that the key has the incorrect value. In the following example, the key contains a string value, and we add an integer value, resulting in an error.
Code:LPUSH color 1 TYPE color
We can insert the data into the key when it holds the type as list. In the below example, the key name redis_LPUSH1 is holding the type as list, so we can be able to insert the element into the specified key.
Code:Type redis_lpush1 LPUSH redis_lpush1 "val" LRANGE redis_lpush1 0 1
The below example shows how we can insert multiple elements by using the LPUSH command as follows. In the example below, we can see that it works the same as when inserting a single element. In the below example, we are inserting val1, val2, and val3 elements respectively, but we can see that it will retrieve the element as val3, val2, and val1 respectively.
Code:LPUSH redis_lpush2 val1 val2 val3 LRANGE redis_lpush2 0 2
Output:Examples of Redis LPUSH
Given below are the examples mentioned:Example #1
In the example below, we are inserting a single element. As shown below, we define the key name as color1 and the value as white. We are also retrieving the value using the lrange method.
Code:LPUSH color1 "white" LRANGE color1 0 1
In the example below, we are inserting a single element. As shown below, we define the key name as color1 and the value as blue, red, and yellow. We are also retrieving the value using the lrange method.
Code:LPUSH color1 "blue" "red" "yellow" LRANGE color1 0 2 LRANGE color1 0 3
In the below example, we are adding two integer elements by using LPUSH.
Code:LPUSH integer_key 11 13 LRANGE integer_key 0 2
The redis LPUSH command inserts the specified values that were heading into the value from the specified key. It is possible to push multiple elements with a single command by using it. It is used to insert the value specified in the head list and saved it in the key.Recommended Articles
