How to use default_hidden_columns filter in WordPress

default_hidden_columns filter

Filters the default list of hidden columns.

To use default_hidden_columns 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 weplugins_modify_default_hidden_columns_defaults which takes 2 parameters and we registered using add_filter. The first parameter default_hidden_columns is the name of the hook, the second parameter weplugins_modify_default_hidden_columns_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 default_hidden_columns filter.

Parameters

Below are the 2 parameters required to use this hook.

• $hidden : (string[]) Array of IDs of columns hidden by default.
• $screen : (WP_Screen) WP_Screen object of the current screen.

Live Examples

Example 1: Basic Usage

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

    function weplugins_modify_default_hidden_columns_defaults($hidden, $screen) { 
        // Update the $hidden variable according to your website requirements and return this variable. You can modify the $hidden variable conditionally too if you want.
        return $hidden; 
    }
    // add the filter
    add_filter( "default_hidden_columns", "weplugins_modify_default_hidden_columns_defaults", 10, 2 );
    

Example 2: Removing the Hook

To remove a hook callback, use the example below.

    remove_filter( "default_hidden_columns", "weplugins_modify_default_hidden_columns_defaults", 10, 2 );
    

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

Example 3: Conditional Modification

Here is an example of how to modify the hidden columns based on certain conditions.

    function weplugins_modify_hidden_columns_conditionally($hidden, $screen) { 
        if ($screen->id === 'edit-post') {
            $hidden[] = 'author';
        }
        return $hidden; 
    }
    // add the filter
    add_filter( "default_hidden_columns", "weplugins_modify_hidden_columns_conditionally", 10, 2 );
