Understanding the Problem
The main problem you were facing is that you needed to add wp_enqueue_script
and wp_localize_script
to your WordPress plugin, but when you did so, the JavaScript file was not working as expected. This is a common issue that many WordPress plugin developers encounter.
The reason for this is that WordPress has a specific way of handling JavaScript files and AJAX requests within a plugin. Simply including the JavaScript file is not enough; you need to use the wp_enqueue_script
function to properly register and enqueue the script, and then use wp_localize_script
to pass any necessary variables from PHP to JavaScript.
The Importance of wp_enqueue_script
and wp_localize_script
In WordPress, the wp_enqueue_script
function is used to register and enqueue a JavaScript file. This function ensures that the script is properly loaded and available to your plugin's JavaScript code.
The wp_localize_script
function is used to pass variables from PHP to the JavaScript file. This is crucial when you need to pass data, such as AJAX URLs or other dynamic values, from the server-side to the client-side.
By using these two functions together, you can ensure that your JavaScript file has access to the necessary data and can properly interact with the WordPress environment.
The wp_register_script
Workaround
You mentioned that you found a workaround using wp_register_script
instead of wp_enqueue_script
. This approach can work in some cases, but it's not the recommended way to handle JavaScript files in a WordPress plugin.
The wp_register_script
function is used to register a JavaScript file, but it does not automatically enqueue the script. This means that the script will not be loaded on the page unless you manually enqueue it using another function, such as wp_enqueue_scripts
.
While this workaround may work in some situations, it's generally better to use the wp_enqueue_script
and wp_localize_script
combination, as it provides a more robust and reliable way to manage your plugin's JavaScript dependencies.
Step-by-Step Solution
- Enqueue the JavaScript File: In your WordPress plugin's PHP file, use the
wp_enqueue_script
function to register and enqueue your JavaScript file. This ensures that the script is properly loaded on the page.
function my_enqueue() {
wp_enqueue_script('linked-plugin-script', plugins_url('/public/js/tinymce/plugins/linked/plugin.js', __FILE__), array('jquery'), '1.0.0', true);
}
add_action('admin_enqueue_scripts', 'my_enqueue');
- Localize the Script: Use the
wp_localize_script
function to pass any necessary variables from PHP to the JavaScript file. In your case, you need to pass the AJAX URL and any other variables required by your AJAX request.
function my_enqueue() {
wp_enqueue_script('linked-plugin-script', plugins_url('/public/js/tinymce/plugins/linked/plugin.js', __FILE__), array('jquery'), '1.0.0', true);
wp_localize_script('linked-plugin-script', 'ajax_object', array(
'ajax_url' => admin_url('admin-ajax.php'),
'whatever' => ''
));
}
add_action('admin_enqueue_scripts', 'my_enqueue');
- Handle the AJAX Request: In your JavaScript file, you can now access the
ajax_object
variable, which contains the AJAX URL and any other variables you passed from PHP. Use this information to make the AJAX request and pass the necessary data to your PHP function.
(function() {
tinymce.PluginManager.add('linked', function(editor, url) {
editor.addButton('linked_button_key', {
text: 'Semantic Notation',
icon: false,
onclick: function() {
var content = tinymce.activeEditor.getContent({format: 'text'});
$.ajax({
type: 'POST',
url: ajax_object.ajax_url,
data: {
'action': 'my_action',
'whatever': ajax_object.whatever = content
},
beforeSend: function() {
console.log('before send..');
},
success: function(response) {
console.log('Success the result is ' + response);
}
});
}
});
});
})();
By following these steps, you can ensure that your WordPress plugin can properly pass variables from AJAX to PHP, even when working with a TinyMCE plugin.
Remember, the key to success is using the wp_enqueue_script
and wp_localize_script
functions together to manage your plugin's JavaScript dependencies and pass necessary data from the server-side to the client-side.
If you're still experiencing issues, double-check your code and ensure that you're properly enqueuing and localizing your script. You may also want to review the WordPress documentation for more information on working with JavaScript in WordPress plugins.
