Question

I am using Jcrop plugin to crop an image.

I upload my photo with a standard html form.
I show my last uploaded image with the following code:

 <img id="cropbox" src="<?php echo $target ?>" width="400" />

This looks like the following:

My code for $target looks like this:

 <?php 
     $target = "uploads/"; 
     $target = $target . basename( $_FILES['filename']['name']) ; 
     $ok=1; 
     if(move_uploaded_file($_FILES['filename']['tmp_name'], $target)) 
     {
     echo "De afbeelding *". basename( $_FILES['filename']['name']). "* is geupload naar de map 'uploads'";
     } 
     else {
     echo "Sorry, er is een probleem met het uploaden van de afbeelding.";
     }
 ?> 

Now i can start selecting my area to crop:

Now i want to save the selected crop area to a new jpg image using the following code:

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $targ_w = 200;
    $targ_h = 400;
    $jpeg_quality = 90;

    $src = '';
    $img_r = imagecreatefromjpeg($src);
    $dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

    imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
    $targ_w,$targ_h,$_POST['w'],$_POST['h']);

    header('Content-type: image/jpeg');
    imagejpeg($dst_r,NULL,$jpeg_quality);

    exit;
}

?>

My question is now, how do i use that $target Source i used to show the image i just uploaded in that php code above?

I have no idea.

You can put the path to file into $_SESSION when uploading the target. In your uploaded.php use this code (here you start the session with session_start() and put the formed target path to $_SESSION array):

 <?php 
 session_start();
 $target = "uploads/"; 
 $target = $target . basename( $_FILES['filename']['name']) ; 
 $_SESSION['target_path'] = $target;

 $ok=1; 
 if(move_uploaded_file($_FILES['filename']['tmp_name'], $target)) 
 {
 echo "De afbeelding *". basename( $_FILES['filename']['name']). "* is geupload naar de map 'uploads'";
 } 
 else {
 echo "Sorry, er is een probleem met het uploaden van de afbeelding.";
 }
?> 

In your crop.php:

<?php
session_start();
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$targ_w = 200;
$targ_h = 400;
$jpeg_quality = 90;

$src = $_SESSION['target_path'];
$img_r = imagecreatefromjpeg($src);
$dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
$targ_w,$targ_h,$_POST['w'],$_POST['h']);

header('Content-type: image/jpeg');
imagejpeg($dst_r,NULL,$jpeg_quality);

exit;
}

?>
