How to use print_admin_styles filter in WordPress

print_admin_styles filter

Filters whether to print the admin styles.

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

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_print_admin_styles_defaults which takes 1 parameter and we registered using add_filter. The first parameter print_admin_styles is the name of the hook, The second parameter modify_print_admin_styles_defaults is the name of the function which needs 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 have to remove a registered hook so you can use remove_filter to remove print_admin_styles filter.

Parameters

Below the 1 parameter is required to use this hook.

• $print: (bool) Whether to print the admin styles. Default true.

Live Example 1: Basic Usage

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

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

Live Example 2: Conditional Modification

Example of modifying the $print variable based on a condition.

    function weplugins_modify_print_admin_styles_conditional($print) { 
        if (is_admin()) {
            // Only print styles on admin pages
            return true;
        }
        return false; 
    }
    // Add the filter
    add_filter("print_admin_styles", "weplugins_modify_print_admin_styles_conditional", 10, 1);
    

Live Example 3: Removing the Hook

To remove a hook callback, use the example below.

    // Remove the filter
    remove_filter("print_admin_styles", "weplugins_modify_print_admin_styles_defaults", 10, 1);
