I am using a form to upload an image. Upon image upload, we will be able to see the uploaded image. Then I used JCrop
(http://deepliquid.com/content/Jcrop.html) to allow cropping for this image. Let's assume I only care about JPEG
images. I am then ready to submit the form.
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 $_FILES
array (this is a must). How would I go about manipulating this $_FILES
array in a PHP script?
Here is what I had attempted and it would not work.
$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);
$message = "<img src='http://localhost/~user/tmp/".$file_name."'>";
$_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']);
It is allowable to change this $_FILES
array?
Only changing in the global array won't work. You are just saying $_FILES['image']['tmp_name']
will be the newly created one. But the tmp location is having same old file.
But you have to update the image in /tmp
folder.
Get your tmp
path and copy
the image there.
kind of copy($newImage, /tmp)
- get your tmp folder path from php.ini
