Hey guys i am trying to crop uploaded image using php using following code.

if(isset($_POST["Crop"])){  
    $source_x=$_POST['x_value'];
    $source_y=$_POST['y_value'];
    $width=$_POST['w_value'];
    $height=$_POST['h_value'];

    $src="assets/images/uploads/1509432972_Koala.jpg";
    $crop = imagecreatetruecolor($width,$height); 
    imagecopy ($crop, $src, 0, 0, $source_x, $source_y, $width, $height); 
    imagejpeg($crop); 
    imagedestroy($src);
    imagedestroy($crop);
}

The problem that it is not working properly. Since there are lot of posts there to solve this, found a solution called GD library how to include it and crop all kind of images.

imagecopy seems to expect a resource at 2nd parameter, not the file path ? – nithinTa Nov 01 '17 at 04:36
