How to use dynamic_sidebar_params action in WordPress

dynamic_sidebar_params action

Note: The filter is evaluated on both the front end and back end, including for the Inactive Widgets sidebar on the Widgets screen.

To use dynamic_sidebar_params action, first you have to register it using add_action. 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 execute_on_dynamic_sidebar_params_event which takes 1 parameter and we registered using add_action. The first parameter dynamic_sidebar_params is the name of the hook, the second parameter execute_on_dynamic_sidebar_params_event 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.

Sometime, you have to remove a registered hook so you can use remove_action to remove dynamic_sidebar_params action.

Example 1: Adding Custom Logic to Sidebar Parameters

Here’s how you can modify the sidebar parameters with custom logic.

    function weplugins_execute_on_dynamic_sidebar_params_event($params){
        // Add custom logic here
    }
    add_action("dynamic_sidebar_params", "weplugins_execute_on_dynamic_sidebar_params_event", 10, 1);
    

Example 2: Removing a Hook Callback

If you need to remove a previously registered hook, follow this example.

    remove_action("dynamic_sidebar_params", "weplugins_execute_on_dynamic_sidebar_params_event", 10, 1);
    

Example 3: Displaying Custom Fields in Widgets

This example shows how to append a custom field at the end of the widget control form.

    if (!function_exists('weplugins_display_custom_field_in_widget_form')) {
        add_action('in_widget_form', 'weplugins_display_custom_field_in_widget_form', 10, 3);
        function weplugins_display_custom_field_in_widget_form($widget, $return, $instance) {
            $column = isset($instance['column']) ? $instance['column'] : '';
            ?>
            <p>
                <label for="<?php echo esc_attr($widget->get_field_id('column')); ?>">Column Label</label>
                <input class="widefat" id="<?php echo esc_attr($widget->get_field_id('column')); ?>" name="<?php echo esc_attr($widget->get_field_name('column')); ?>" type="text" value="<?php echo esc_attr($column); ?>" />
            </p>
            <?php
        }
    }
