How to use install_themes_table_api_args_tab filter in WordPress

install_themes_table_api_args_tab filter

Okay, let’s dive into the install_themes_table_api_args_tab filter. This hook is quite interesting as it allows you to modify the theme install API arguments based on the theme install tab. To use this filter, you first need to register it using add_filter. You can place this code in the functions.php file of your active theme or, better yet, create a custom WordPress Plugin. At WePlugins, we always recommend going the plugin route, so your changes remain intact even after a theme update.

In this example, we’ve defined a function modify_install_themes_table_api_args_tab_defaults that takes one parameter. We’ve registered it using add_filter. The steps are straightforward: the first parameter is the hook name, the second is your custom function, the third is the priority, and the last is the number of arguments. If needed, you can also remove a registered hook using remove_filter.

Example 1: Basic Hook Usage

This example shows how to apply the filter.

    apply_filters( "install_themes_table_api_args_{$tab}", array|false $args )
    

Example 2: Modify API Arguments

Here’s how you can use the hook to modify API arguments according to your website’s needs.

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

Example 3: Removing the Hook

To remove a hook callback, you should use this example.

    remove_filter( "install_themes_table_api_args_tab", "weplugins_modify_install_themes_table_api_args_tab_defaults", 10, 1 );
    

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