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);

Answer 3

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.
