I'm trying to add a nonce to my plugin's Ajax. I'm not sure why I'm getting this error:

Fatal error: Call to undefined function wp_create_nonce()

In my php file : 

wp_localize_script('my-ajax-handle', 'the_ajax_script', array('ajaxurl'=> admin_url('admin-ajax.php'), 'my_nonce' => wp_create_nonce('myajax-nonce')));

In js file: 

jQuery.post(the_ajax_script.ajaxurl, {my_nonce : the_ajax_script.my_nonce}, jQuery("#theForm").serialize() + "&maxLat="+ map_bounds[0] + "&maxLong="+ map_bounds[1] + "&minLat="+ map_bounds[2] + "&minLong="+ map_bounds[3], function(response_from_the_action_function){ jQuery("#response_area").html(response_from_the_action_function); });

Any suggestions on how to solve this?

Thank you.

More context would be helpful. Is that all the code found in your plugin or functions file directly? Or are you hooking in to something via add_action.

Anyway, what's probably wrong is that you're calling wp_localize_script and wp_enqueue_script outside of an action. wp_create_nonce, or, rather, the file in which it resides, has yet to be loaded.

The solution is to call wp_localize_script from inside a function hooked into wp_enqueue_scripts

<?php add_action( 'wp_enqueue_scripts', 'wpse30583_enqueue' ); function wpse30583_enqueue() { // your enqueue will probably look different. wp_enqueue_script( 'wpse30583_script' ); // Localize the script $data = array( 'ajax_url' => admin_url( 'admin-ajax.php' ), 'nonce' => wp_create_nonce( 'wpse30583_nonce' ) ); wp_localize_script( 'wpse30583_script', 'wpse3058_object', $data ); }

  • Hi, @Christopher Davis, Thank you very much for your message. You're right, I didn't have wp_localize_script inside a function. I never would have thought of your solution. I plopped it in a function and now I don't get the fatal error anymore. Unfortunately, I must have a second bug. I don't think that the nonce is being posted. Does this bit look correct: jQuery.post(the_ajax_script.ajaxurl, {my_nonce : the_ajax_script.my_nonce}, jQuery("#theForm").serialize()... Also, I tried putting an echo in php and alert on the js. It looks like the 2 numbers are different. Is this normal? Thank you. Commented Oct 10, 2011 at 20:20
  • Better ask that in a separate question. Maybe someone else has had a similar issue. Commented Oct 10, 2011 at 20:38
  • I was thinking about doing that. I'll go ahead and post a new one. Thank you very much for the help! Commented Oct 10, 2011 at 20:43
