What is WordPress Hook: mce_buttons
The mce_buttons hook in WordPress is used to add or remove buttons from the TinyMCE editor, which is the visual editor used for creating and editing posts and pages in WordPress.
Understanding the Hook: mce_buttons
The mce_buttons hook is located within the functions.php file of a WordPress theme or in a custom plugin. It allows developers to customize the buttons available in the TinyMCE editor by adding or removing specific buttons based on their requirements.
Hook Parameters (if applicable): mce_buttons
The mce_buttons hook does not accept any parameters. It simply allows developers to modify the buttons available in the TinyMCE editor.
Hook Doesn’t Work: mce_buttons
If the mce_buttons hook doesn’t work as expected, it could be due to a conflict with another plugin or theme function that is also modifying the TinyMCE editor buttons. To troubleshoot, developers should deactivate other plugins or switch to a default theme to identify the conflicting code.
Best Practices & Usage Notes (if applicable): mce_buttons
When using the mce_buttons hook, it’s important to consider the user experience and only add or remove buttons that are necessary for the content creation process. Overloading the editor with unnecessary buttons can confuse users and make the editing experience more complex.
Usage Example: mce_buttons
“`php
function custom_mce_buttons($buttons) {
// Remove the underline button from the TinyMCE editor
$remove = ‘underline’;
$pos = array_search($remove, $buttons);
if ($pos !== false) {
unset($buttons[$pos]);
}
return $buttons;
}
add_filter(‘mce_buttons’, ‘custom_mce_buttons’);
