    copied!<p>I'm trying to use wordpress' built-in ajax to process an upload using the AjaxUpload script. The script was updated in august, and now i can't get it to work any more. </p> <p><a href="http://valums.com/ajax-upload/" rel="nofollow noreferrer">http://valums.com/ajax-upload/</a></p> <p>here's my jquery... this seems to be in place as i get input is transformed into an upload button and on selection of the image it begins to attempt to upload automatically.</p> <pre><code>jQuery.noConflict(); jQuery(document).ready(function($) { /* * AJAX UPLOAD * http://valums.com/ajax-upload/ */ var uploader = new qq.FileUploader({ // pass the dom node (ex. $(selector)[0] for jQuery users) element: document.getElementById('file-uploader'), // path to server-side upload script action: ajaxurl, params: { type: "POST", action: 'save_function', key: 'logo', }, onComplete: function(id, fileName, responseJSON){ console.debug("Here is the response: %o", responseJSON); } }); }); //end document.ready functions </code></pre> <p>my action is set to ajaxurl which is the constant for /wp-admin/admin-ajax.php, i passed an action in the params so that admin-ajax would know what function i wanted to run to process things. and my callback function</p> <pre><code>function childtheme_data_save_callback() { global $my_shortname; $id = $_POST['key']; // option name $upload = wp_handle_upload($_FILES['qqfile']['tmp_name'], array('test_form' =&gt; false)); if(!empty($upload['error'])) { //there IS an error message die($upload['error']); } else { // there is NOT an error $upload_image = $my_data; //preserve current data $upload_image[$id] = $upload['url']; update_option($my_shortname .'_options', $upload_image ) ; die($upload['url']); //response sends url back to jquery } } add_action('wp_ajax_save_function', 'childtheme_data_save_callback'); </code></pre> <p>which is getting called and my error message is showing in my firebug console. here is the error</p> <p>File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini or by post_max_size being defined as smaller than upload_max_filesize in php.ini.</p> <p>dabbling w/ changing the error messasge to $_FILES it always comes back an empty array, even though in console it says the POST is filled w/ stuff that looks like </p> <pre><code>ÿØÿà�JFIF��_�_��ÿÛ�C� $.' ",#(7),01444'9=82&lt;.342ÿÛ�C 2!!22222222222222222222222222222222222222222222222222ÿÀ�° </code></pre> <p>and more. though now i see that console also says the Response Headers have a content type of: Content-Type text/html; charset=UTF-8</p> <p>and the request headers accept: Accept text/html,application/xhtml+xml,application/xml;q=0.9,<em>/</em>;q=0.8</p> <p>is the problem then in not sending the POST in "multipart/form-data" encoding? if so how do i switch to that since i'm using this plugin and not a form tag? if not, well i have been stumped for a while now.</p>
