What is WordPress Hook: tiny_mce_before_init
The tiny_mce_before_init hook is a specific hook in WordPress that allows developers to modify the settings of the TinyMCE (Tiny Moxiecode Content Editor) before it is initialized.
Understanding the Hook: tiny_mce_before_init
The tiny_mce_before_init hook is located within the wp-includes/class-wp-editor.php file in the WordPress core. It is called just before the TinyMCE editor is initialized, allowing developers to modify the editor settings before it is loaded on the page.
Hook Parameters (if applicable): tiny_mce_before_init
The tiny_mce_before_init hook accepts an array of parameters that can be modified by developers. These parameters include settings such as the toolbar, plugins, and formatting options for the TinyMCE editor.
Hook Doesn’t Work: tiny_mce_before_init
If the tiny_mce_before_init hook doesn’t work as expected, it may be due to conflicts with other plugins or themes that are also modifying the TinyMCE settings. To troubleshoot, developers can try disabling other plugins or themes to see if there is a conflict. Additionally, checking for syntax errors in the code modifying the hook can also help identify issues.
Best Practices & Usage Notes (if applicable): tiny_mce_before_init
When using the tiny_mce_before_init hook, it’s important to be mindful of potential conflicts with other plugins or themes that may also be modifying the TinyMCE settings. Additionally, developers should carefully review the TinyMCE documentation to understand the available settings and how they can be modified using the hook.

return $initArray;
}
add_filter(‘tiny_mce_before_init’, ‘custom_tinymce_settings’);
