    <p>I've been working with the upload feature since the second iOS6 beta release. The following code works for me:</p> <p>Put this in the head of your HTML page -</p> <pre><code>&lt;script&gt;window.onload = function() { var canvas = document.createElement('canvas'); var ctx = canvas.getContext("2d"); var fileSelect = document.getElementById("fileSelect"), input = document.getElementById("input"); input.addEventListener("change", handleFiles); //hides ugly default file input button fileSelect.addEventListener("click", function (e) { if (input) { input.click(); } e.preventDefault(); }, false); function handleFiles(e) { var reader = new FileReader; reader.onload = function (event) { var img = new Image(); img.src = reader.result; img.onload = function () { var maxWidth = 320, maxHeight = 350, imageWidth = img.width, imageHeight = img.height; if (imageWidth &gt; imageHeight) { if (imageWidth &gt; maxWidth) { imageHeight *= maxWidth / imageWidth; imageWidth = maxWidth; } } else { if (imageHeight &gt; maxHeight) { imageWidth *= maxHeight / imageHeight; imageHeight = maxHeight; } } canvas.width = imageWidth; canvas.height = imageHeight; ctx.drawImage(this, 0, 0, imageWidth, imageHeight); // The resized file ready for upload var finalFile = canvas.toDataURL("image/png"); var postData = 'canvasData=' + finalFile; var ajax = new XMLHttpRequest(); ajax.open('POST', 'save.php', true); ajax.setRequestHeader('Content-Type', 'canvas/upload'); ajax.onreadystatechange = function () { if (ajax.readyState == 4) { //just to visually confirm it worked... window.open(canvas.toDataURL("image/png"), "mywindow"); } } ajax.send(postData); } } reader.readAsDataURL(e.target.files[0]); } } &lt;/script&gt; </code></pre> <p>Here's the HTML -</p> <pre><code> &lt;div style="width:320px;position:absolute;z-index:9;top:387px;"&gt; &lt;button style="width:60px;" id="fileSelect"&gt;upload&lt;/button&gt; &lt;input type="file" id="input" name="input" accept="image/*" style="display:none;"&gt;&lt;/div&gt; </code></pre> <p>Here's the PHP -</p> <pre><code>&lt;?php if (isset($GLOBALS["HTTP_RAW_POST_DATA"])) { // Get the data $imageData=$GLOBALS['HTTP_RAW_POST_DATA']; // Remove the headers (data:,) part. // A real application should use them according to needs such as to check image type $filteredData=substr($imageData, strpos($imageData, ",")+1); // Need to decode before saving since the data we received is already base64 encoded $unencodedData=base64_decode($filteredData); // Save file. This example uses a hard coded filename for testing, // but a real application can specify filename in POST variable $fp = fopen( 'users/user_photo.png', 'wb' ); fwrite( $fp, $unencodedData); fclose( $fp ); } ?&gt; </code></pre> <p>The only issue I've battled with is getting images to load from the camera without being rotated 90 degrees.</p> <p>Hope this helps, let me know if you've any issues with the code (it's my first post).</p>

    1. COFantastic. I will work with the code and see if I can come up with a solution for the 90 degree rotation. Anyone else have a solution for this?

    2. COHave you found this solution to work on the iPhone IO6 with pictures taken from the camera. I have found that any images that are resized using this method works but the image is squashed and not as expected.

    3. COHave a look at this implementation. This works fine on Chrome on a normal OS but on IOS when resizing the image it does something weird http://jsfiddle.net/Untd8/

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.
