To realize the function of reminding to install plug-ins in WordPress through pure code, you can use the following steps:
-
Open the functions.php file of your theme. This file is usually located in the/wpcontent/themes/yourthemename/directory.
-
Add the following code to the functions.php file to check whether the specified plug-in is installed, and display a reminder message when it is not installed:
function check_required_plugin() { if ( ! is_plugin_active( 'pluginfolder/pluginfile.php' ) ) { ?> <div class="notice noticeerror"> <p><? Php _e ('Please install and activate the plug-in to enable this function. ',' yourtextdomain' ); ?></p> </div> <? php } } add_action( 'admin_notices', 'check_required_plugin' );
In the above code 'pluginfolder/pluginfile.php' Replace with the file path of the plug-in you want to check. 'yourtextdomain' It is the text field of your topic for international/localized translation. You can customize the reminder message as needed.
-
Save and upload the functions.php file to your WordPress theme directory.
-
When users log in to the WordPress background, if they do not install and activate the specified plug-in, they will see an error reminder, prompting them to install and activate the plug-in.
Please note that this method only displays a reminder message when users access the WordPress background. If they have installed and activated the plug-in, they will not see any reminder. Make sure to replace the plug-in path and reminder message in the code to meet your specific needs.
