Here is my controller.php code.

if(isset($_FILES['file']['name'])){ //user upload file
    $file_name = stripslashes($_FILES['file']['name']);
    $ext_idx = strrpos($file_name,".");
    if(!$ext_idx) //hide this if ur app can upload without ext
        echo "File invalid.";
    else{
        $ext_length = strlen($file_name) - $ext_idx;
        $extension = strtolower(substr($file_name,$ext_idx+1,$ext_length));
        //allowed extension
        $ext_list = array("pdf", "doc","jpg", "jpeg", "gif", "png");
        if(!in_array($extension, $ext_list))
            echo "System can't support your extension.";
        else{
            $size = (2500 * 1024); //2500 Kb
            $file_size=filesize($_FILES['file']['tmp_name']);
            if($file_size > $size)
                echo "File is oversize. Max 2500 Kb.";
            else{
                //change name
                $file_name = "image".rand(10,1000).".".$extension;

                $file_obj="public/image/".$file_name;



                $copied = copy($_FILES['file']['tmp_name'], $file_obj);

                if(!$copied)
                    echo "Failed.";
                else 
                {

                    $file_data = array( 'file_name' => $file_name );


                    $this->view->file_obj=$file_obj;




                }
                }

            }
        }
    }
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
 $targ_w = $targ_h = 150;
 $jpeg_quality = 90;
 $src = "public/image/".$file_name;

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

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

//header('Content-type: image/jpeg');
  imagejpeg($dst_r,"public/image/crop/".$file_name,$jpeg_quality);

   }

Answer 1

Look at this "imagecreatefromjpeg(public/image/)" - this is NOT a image resource. It only works with a valid file resource like

imagecreatefromjpeg('public/image/test.jpg');

Answer 2

try this code:

    $a="./images/".$file_name;
    list($width, $height) = getimagesize($a);
    $newwidth = "300"; 
    $newheight = "200";
    $thumb = imagecreatetruecolor($newwidth, $newheight);
    $source = imagecreatefromjpeg($a);
    imagecopyresized($dest, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
    imagejpeg($dest, $a, 100);

Warning: imagecreatefromjpeg(public/image/)

your path is not correct you should use the absolute path with __DIR__ for example.

imagecreatefromjpeg(__DIR__."public/image/test.jpg");

and your filename is missing. The next errors result from the first error that your image can't load.
