How to use allow_empty_comment filter in WordPress

Example 1: Enabling Empty Comments

Sometimes, you might want to allow empty comments on your site for various reasons. Here’s how you can enable them using the allow_empty_comment filter.

    // Enable empty comment.
    add_filter( 'allow_empty_comment', '__return_true' );
    

Example 2: Modifying Comment Approval Logic

In this example, we’ll modify the default behavior of the allow_empty_comment filter to suit specific needs. You can adjust the logic in your custom function to determine when an empty comment should be allowed.

    function weplugins_modify_allow_empty_comment_defaults($allow_empty_comment, $commentdata) { 
        // Update the $allow_empty_comment variable according to your website requirements.
        return $allow_empty_comment; 
    }
    // Add the filter
    add_filter( "allow_empty_comment", "weplugins_modify_allow_empty_comment_defaults", 10, 2 );
    

Example 3: Removing a Hook Callback

If you need to remove a previously registered hook, use the remove_filter function. Here’s how you can do it for the allow_empty_comment filter.

    remove_filter( "allow_empty_comment", "weplugins_modify_allow_empty_comment_defaults", 10, 2 );
    

Please ensure to provide the same callback function name, priority, and number of arguments when removing the hook callback.
