As a WordPress website owner, you may encounter various errors and warning messages while managing your site. While WordPress does a great job of displaying these messages, it’s sometimes not enough to fully understand the problem and its solution. In such cases, it can be helpful to display custom error messages in the WordPress admin area. This can be done by adding a few lines of code to your theme’s functions.php file or by using a plugin.

Why Display Custom Error Messages?

There are several reasons why you may want to display custom error messages in the WordPress admin area. Some of the most common reasons include:

• To provide a clearer explanation of the problem and its solution.
• To display more specific information about the error, such as the exact line of code causing the problem.
• To improve the user experience by making it easier to understand and resolve errors.

How to Display Custom Error Messages

There are two main ways to display custom error messages in the WordPress admin area: using code or using a plugin. Let’s take a look at both methods.

Method 1: Using Code

This method involves adding a few lines of code to your theme’s functions.php file. Here’s how:

1. Access the functions.php file: To access the functions.php file, log in to your WordPress dashboard and go to Appearance > Theme Editor. Select the functions.php file from the list on the right-hand side.
2. Add the code: Once you have the functions.php file open, add the following code:

function my_error_notice() {
    ?>
    <div class="notice notice-error">
        <p><?php _e( 'There is an error with your site configuration. Please contact your developer for assistance.', 'text-domain' ); ?></p>
    </div>
    <?php
}
add_action( 'admin_notices', 'my_error_notice' );

3. Replace the text: Replace the text in the code with your custom error message.
4. Save the file: After making your changes, click the “Update File” button to save your changes.

Method 2: Using a Plugin

If you’re not comfortable adding code to your site, you can use a plugin to display custom error messages in the WordPress admin area. One of the most popular plugins for this is the “Admin Notices” plugin. Here’s how to use it:

1. Install the plugin: Log in to your WordPress dashboard and go to Plugins > Add New. Search for “Admin Notices” and install the plugin.
2. Configure the plugin: Once the plugin is installed and activated, go to Settings > Admin Notices to configure the plugin.
3. Create a new notice: Click the “Add New” button to create a new notice. Fill in the “Content” field with your custom error message and select the “Error” type.
4. Save the notice: After making your changes, click the “Save” button to save your new notice.

That’s it! You should now see your custom error message displayed in the WordPress admin area.

Conclusion

Displaying custom error messages in the WordPress admin area can be a helpful way to provide more information and context when an error occurs. Whether you choose to use code or a plugin, the process is straightforward and can make it easier to manage and troubleshoot your WordPress site.
