    <p>I've been looking into uploading files via. AJAX using FormData and FileReader, but I keep running into the same problem.</p> <p>Upon triggering the file upload, it is passed to a PHP script which validates the uploaded file and attempts to move it into a permanent directory. Unfortunately, whilst validation is successful, calling <code>move_uploaded_file()</code> results in the following warnings:</p> <blockquote> <p><strong>Warning</strong>: move_uploaded_file(<em>[path\to\temp\directory]</em>\php256.tmp): failed to open stream: No such file or directory in <strong>[path/to/script/file.php]</strong> on line <strong>[line]</strong></p> <p><b>Warning</b>: move_uploaded_file(): Unable to move '<em>[path\to\temp\directory]</em>\php256.tmp' to '<em>[path\to\permanent\directory]\[filename.ext]</em>' in <strong>[path/to/script/file.php]</strong> on line <strong>[line]</strong><br /></p> </blockquote> <p>Uploading files via submitting a form normally and moving the temporary file works as expected.</p> <p>My php.ini settings are pretty standard:</p> <pre class="lang-none prettyprint-override"><code>file_uploads = On upload_tmp_dir = "[path\to\temp\directory]" upload_max_filesize = 2M max_file_uploads = 20 </code></pre> <p>My PHP should also be pretty standard:</p> <pre class="lang-php prettyprint-override"><code>$fileField = 'target_file'; if(!(isset($_FILES) &amp;&amp; is_array($_FILES) &amp;&amp; isset($_FILES[$fileField]))) { // No File Sent (Error Out) } $file = $_FILES[$fileField]; // Errors in transfer? if(isset($file['error'])) { $haltMessage = false; switch($file['error']) { /* Switchboard checking through all standard file upload errors. And, of course, ERR_OK */ } if($haltMessage !== false) { // An error occured! Error Out } } // Check if the file was uploaded. if(!is_uploaded_file($file['tmp_name'])) { // No File Uploaded (Error Out) } if(/* File type checking.. */)) { // Invalid file type (Error Out) } $uploadDir = 'path/to/permanent/dir'; $fileName = $file['name']; $location = $uploadDir . DS . basename($fileName); // DS = '/' $result = move_uploaded_file($file['tmp_name'], $location); if($result) { // Yes! } else { // Something did indeed go wrong. // This block of code is ran after the warnings are issued. } </code></pre> <p>So that leaves my JavaScript to be somewhat desired:</p> <pre class="lang-js prettyprint-override"><code>(function($) { $(document).ready(function(){ var url = 'url/to/php/script.php', input, formdata; // FormData support? (We have a fallback if not) if(window.FormData != null &amp;&amp; window.FileReader != null) { input = document.getElementById('target_file'); formdata = new FormData(), input.addEventListener('change', function(ev) { var reader, file; if(this.files.length === 1) { file = this.files[0]; if(!!file.type.match(/* File type matching */)) { reader = new FileReader(); reader.onloadend = function (e) { // Uploaded Handle } reader.onload = function() { formdata.append('target_file', file); $.ajax({ url : url, type : "POST", data : formdata, processData: false, contentType: false, success : function(res) { console.log(res); } }); } reader.readAsDataURL(file); } else { // Invalid file type. } } else { // No file / too many files (hack) selected. } }, false); } }); }(jQuery)); </code></pre> <p>I'm using FireFox 23.0.1, and I'm running PHP 5.4.7 on the server.</p> <p>Apologies for the long question, but I'm not sure where the problem seems to be. Dumping the $_FILES variable reveals an array that's full of the expected file information, including a tmp_name too. There's no sign of any error at that point, only when I attempt to move the temp file.</p> <p>Any help you can give in regards to this question would be much appreciated!</p>

    1. COWhy are you using FileReader here at all? It is completely unnecessary and inefficient to do so unless you actually want to, for example, read the contents of each file. There is no need to read a file if you are simply uploading it. In fact, after the file is read, you're not even doing anything with the contents of the file.

    2. COI was trying a bunch of alternate suggestions, things like reading the file as binary, beforehand. That was the closest solution I could get to a success. Other attempts and tinkering resulted in the file not being passed through to the server at all. As for not doing anything with the read file contents, another suggestion was to pass through the contents instead of just the file variable. That, too, resulted in failure.

    3. CONo need to use FileReader, just append the `File` object your grabbing from your `<input type="file">` to your `FormData` object, and send the `FormData` object along with your ajax request.

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.
