Why is my ajax request getting response 0?

Question

I\'ve setup the basic wordpress ajax example in my wp theme. The trigger is made by modernizr.js checking the media queries on the page.

jQuery(document).rea         


        

Answer 1

Everything has to match here:

PHP

add_action('wp_ajax_my_action',        'my_action');
add_action('wp_ajax_nopriv_my_action', 'my_action');

function my_action() {}

JS

var data = {
    action: 'my_action',
    whatever: ajax_object.we_value 
};

Also, you're missing security checks and a better handling of the response.
Check this examples: [ 1 ] and [ 2 ].
