    <p>I am using a form to upload an image. Upon image upload, we will be able to see the uploaded image. Then I used <code>JCrop</code> (<a href="http://deepliquid.com/content/Jcrop.html" rel="nofollow">http://deepliquid.com/content/Jcrop.html</a>) to allow cropping for this image. Let's assume I only care about <code>JPEG</code> images. I am then ready to submit the form.</p> <p>Upon form submission I will perform some image manipulation and crop the image. However I want to put the information for this cropped image back into the <code>$_FILES</code> array (this is a must). How would I go about manipulating this <code>$_FILES</code> array in a PHP script?</p> <p>Here is what I had attempted and it would not work.</p> <pre><code>$upload_dir = '/Users/user/Sites/tmp/'; $file_name = $_FILES['image']['name']; $file_name = "cropped_".$file_name; $tmp_name = $_FILES['image']['tmp_name']; $file_size = $_FILES['image']['size']; $src_file = imagecreatefromjpeg($tmp_name); list($width,$height) = getimagesize($tmp_name); // Creates cropped image $tmp = imagecreatetruecolor($_POST['w'], $_POST['h']); imagecopyresampled($tmp, $src_file, 0, 0, $_POST['x'], $_POST['y'], $_POST['w'], $_POST['h'], $_POST['w'], $_POST['h']); $small_pic_file_path = $upload_dir.$file_name; imagejpeg($tmp,$small_pic_file_path,85); $message = "&lt;img src='http://localhost/~user/tmp/".$file_name."'&gt;"; $_FILES['image']['name'] = $file_name; $_FILES['image']['type'] = "image/jpeg"; // unlink($tmp_name); // if(!move_uploaded_file($upload_dir.$file_name, $tmp_name)) echo "Failure Moving Image"; $_FILES['image']['tmp_name'] = $upload_dir.$file_name; $_FILES['image']['error'] = 0; $sizes = getimagesize($upload_dir.$file_name); $_FILES['image']['size'] = ($sizes['0'] * $sizes['1']); </code></pre> <p>It is allowable to change this <code>$_FILES</code> array?</p>

    1. COI can't see why it wouldn't be. But you can always make a copy of it an do what you want then.

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.
