    <p>I have a couple AJAX requests being used in a theme options page. Both worked just fine before, but now the first works and the second fails every time - the failure looks like this in Firebug: <a href="http://cl.ly/1w5u" rel="nofollow noreferrer">http://cl.ly/1w5u</a> and this is in Webkit: cl.ly/1wYn. I'm not getting ANY response of any kind. The thing is, the first one works just fine.</p> <p>Here's the JS (jQuery) that submits:</p> <pre><code>jQuery('.cropimage').click(function(){ var pid = jQuery('#tump_header_img').val(); var path = jQuery('#header_img_edit .container img').attr('src'); var dimensions = jQuery('#tump_header_img_position').val(); var security = jQuery('#_ajax_nonce_crop_apply_image').val(); jQuery.post(ajaxurl, {pid: pid, action: 'crop_apply_header_image', path: path, dimensions: dimensions, security: security}, function(response) { console.log(response); }); }); </code></pre> <p>ajaxurl is correct, it's the exact same URL used in the request that does work. I've tried stripping out everything and just trying to get a response, to no avail.</p> <p>The good stuff in functions.php:</p> <pre><code> add_action('wp_ajax_crop_apply_header_image', 'crop_apply_header_image'); function crop_apply_header_image() { check_ajax_referer('crop_apply_header_image', 'security'); $data = $_POST; unset($data['security'], $data['action']); $dimensions = explode(',',$data['dimensions']); $extension_pos = strrpos($data['path'], '/'); // find position of the last dot, so where the extension starts $newpath = substr($data['path'], 0, ($extension_pos +1)) . 'cropped-' . substr($data['path'], ($extension_pos + 1)); update_option( 'tump_header_img_path', $newpath ); die( wp_crop_image($data['pid'],$dimensions[0],$dimensions[1],$dimensions[2],$dimensions[3],940,200) ); } </code></pre> <p>Anyways - it gets to none of this as far as I can tell. I don't know what's wrong, any help is greatly appreciated!</p>

    1. COWhat fires the `wp_ajax_crop_apply_header_image` action?

    2. COMy terminology isn't going to be perfect here, but basically this does: jQuery.post(ajaxurl, {pid: pid, action: 'crop_apply_header_image'... In wp-ajax.php, add_action() looks for an action prepended by wp_ajax_. Make any sense? That's the way I've learned it works and the way it does successfully work for my other call.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
