This is How to Disable Removing WordPress Widgets but Allow Changing Position/Sidebar
As a WordPress website owner or developer, you may have encountered a frustrating scenario where your users accidentally or intentionally remove important widgets from your site's sidebar or other widget-enabled areas. While you want to give your users the flexibility to customize the layout, you also need to ensure that critical widgets remain in place.
In this article, we'll explore a solution that allows you to disable the removal of WordPress widgets while still enabling users to change their position and sidebar allocation. This approach ensures that your website's core functionality and design remain intact, providing a seamless user experience for both you and your visitors.
The Problem: Accidental or Intentional Widget Removal
WordPress widgets are powerful tools that allow you to add dynamic content, functionality, and customization options to your website. They are often used to display essential information, such as social media feeds, search bars, or email subscription forms, in designated widget areas like sidebars, footers, and custom widget regions.
However, the ability to easily add, remove, and rearrange widgets can sometimes lead to unintended consequences. Users, whether they're site administrators, editors, or even regular visitors, may accidentally or intentionally remove critical widgets, disrupting the overall layout and functionality of your website.
This can be particularly problematic if you have widgets that are essential for your website's performance, such as those responsible for lead generation, e-commerce functionality, or important informational content. Losing these widgets can have a significant impact on your website's effectiveness and user experience.
The Solution: Disable Removing Widgets, Allow Position/Sidebar Changes
To address this issue, we'll use a custom WordPress plugin that disables the removal of widgets while still allowing users to change their position and sidebar allocation. This solution ensures that your critical widgets remain in place, while still providing users with the flexibility to rearrange and customize the widget layout.
Here's how you can implement this solution:
Step 1: Create a New WordPress Plugin
Begin by creating a new WordPress plugin in your site's wp-content/plugins
directory. You can do this by creating a new folder with the name of your plugin, and then adding a PHP file with the same name inside the folder. For example, if your plugin is called "Disable Widget Removal," the folder structure would be:
wp-content/plugins/
├── disable-widget-removal/
└── disable-widget-removal.php
Step 2: Add the Plugin Header
In the disable-widget-removal.php
file, start by adding the plugin header. This identifies your plugin to WordPress and provides essential information about it:
<?php
/*
Plugin Name: Disable Widget Removal
Plugin URI: https://flowpoint.ai
Description: Disables the removal of WordPress widgets while still allowing users to change their position and sidebar allocation.
Version: 1.0
Author: Flowpoint.ai
Author URI: https://flowpoint.ai
*/
Step 3: Disable Widget Removal
To disable the removal of widgets, we'll use the delete_post_meta
and wp_trash_post
actions, which are triggered when a widget is about to be deleted. We'll prevent these actions from occurring, effectively disabling the widget removal functionality.
Add the following code to your plugin file:
add_action( 'delete_post_meta', 'disable_widget_removal', 10, 4 );
function disable_widget_removal( $meta_id, $object_id, $meta_key, $meta_value ) {
if ( 'widget_' === substr( $meta_key, 0, 7 ) ) {
return false;
}
}
add_action( 'wp_trash_post', 'disable_widget_trashing', 10, 1 );
function disable_widget_trashing( $post_id ) {
if ( 'widget' === get_post_type( $post_id ) ) {
return false;
}
}
These functions prevent the deletion of widget-related metadata and the trashing of widget posts, effectively disabling the removal of widgets.

Step 4: Allow Changing Widget Position and Sidebar
While we've disabled the removal of widgets, we still want to allow users to change the position and sidebar allocation of the widgets. To achieve this, we'll use the sidebar_admin_setup
action, which is triggered when the Widgets screen is loaded in the WordPress admin area.
Add the following code to your plugin file:
add_action( 'sidebar_admin_setup', 'enable_widget_position_change' );
function enable_widget_position_change() {
// Allow users to change the position and sidebar of widgets
add_filter( 'widget_display_callback', 'allow_widget_position_change', 10, 3 );
}
function allow_widget_position_change( $instance, $widget, $args ) {
// Allow users to change the sidebar and position of the widget
return $instance;
}
This code ensures that users can still rearrange and move widgets to different sidebars, while preventing them from actually removing the widgets.
Step 5: Optionally, Add a Plugin Settings Page
If you'd like to provide additional customization options for your users, you can create a plugin settings page where they can configure the behavior of the "Disable Widget Removal" plugin. This could include options to whitelist specific widgets that should be removable, or to allow users with certain roles (e.g., administrators) to remove widgets.
To create a plugin settings page, you can use the WordPress Settings API. Here's an example implementation:
// Add the plugin settings page
add_action( 'admin_menu', 'disable_widget_removal_settings_page' );
function disable_widget_removal_settings_page() {
add_options_page(
'Disable Widget Removal Settings',
'Disable Widget Removal',
'manage_options',
'disable-widget-removal',
'disable_widget_removal_settings_page_content'
);
}
// Render the plugin settings page content
function disable_widget_removal_settings_page_content() {
// Add your settings page content here
?>
<div class="wrap">
<h1>Disable Widget Removal Settings</h1>
<form action="options.php" method="post">
<?php
settings_fields( 'disable-widget-removal-settings' );
do_settings_sections( 'disable-widget-removal-settings' );
submit_button();
?>
</form>
</div>
<?php
}
// Register the plugin settings
add_action( 'admin_init', 'disable_widget_removal_register_settings' );
function disable_widget_removal_register_settings() {
register_setting( 'disable-widget-removal-settings', 'disable_widget_removal_settings' );
add_settings_section(
'disable-widget-removal-settings-section',
'Disable Widget Removal Settings',
'disable_widget_removal_settings_section_callback',
'disable-widget-removal-settings'
);
// Add your settings fields here
}
function disable_widget_removal_settings_section_callback() {
echo 'Configure the behavior of the Disable Widget Removal plugin.';
}
This code adds a new "Disable Widget Removal" settings page under the WordPress admin's "Settings" menu. You can then add your custom settings fields and logic within the disable_widget_removal_register_settings
function.

This ensures that your website's core functionality and design remain intact, providing a seamless user experience for both you and your visitors.
