How to use blog_details filter in WordPress

blog_details filter

Filters a blog’s details.

To use the blog_details filter, first register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin.

At WePlugins, we always prefer to create a custom WordPress Plugin when using hooks to ensure nothing breaks when you update your WordPress Theme in the future.

In the example below, we define a function weplugins_modify_blog_details_defaults which takes one parameter and is registered using add_filter. The first parameter blog_details is the name of the hook, the second parameter weplugins_modify_blog_details_defaults is the name of the function to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you need to remove a registered hook, and for that, you can use remove_filter to remove the blog_details filter.

Example 1: Applying the blog_details Filter

Below is an example of how you can use this hook.

    function weplugins_modify_blog_details_defaults($details) { 
        // Update the $details variable according to your website requirements and return this variable. 
        // You can modify the $details variable conditionally too if you want.
        return $details; 
    }
    // add the filter
    add_filter( "blog_details", "weplugins_modify_blog_details_defaults", 10, 1 );
    

Example 2: Removing the blog_details Filter

To remove a hook callback, use the example below.

    remove_filter( "blog_details", "weplugins_modify_blog_details_defaults", 10, 1 );
    

Ensure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Using Deprecated Filters

Here’s how you might handle deprecated filters related to blog details.

    apply_filters_deprecated( 'blog_details', WP_Site $details );
    

Below is an example of handling deprecated filters in your code.

    function weplugins_modify_blog_details_defaults($details) {
        // Logic for modifying blog details
        return $details;
    }
    add_filter( "blog_details", "weplugins_modify_blog_details_defaults", 10, 1 );
