Hello!
I have made at site for my company that are going to upload images, and when the image is uploaded a watermark with copyright are being set in the bottom. But I got errors.

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: Filename cannot be empty in C:\xampp\htdocs\sjohaugbygg\admin\upload.php on line 66
Warning: getimagesize() [function.getimagesize]: Filename cannot be empty in C:\xampp\htdocs\sjohaugbygg\admin\upload.php on line 68
Warning: imagecopymerge() expects parameter 1 to be resource, null given in C:\xampp\htdocs\sjohaugbygg\admin\upload.php on line 73
Warning: imagejpeg() expects parameter 1 to be resource, null given in C:\xampp\htdocs\sjohaugbygg\admin\upload.php on line 75
Warning: imagedestroy() expects parameter 1 to be resource, null given in C:\xampp\htdocs\sjohaugbygg\admin\upload.php on line 77
Column count doesn't match value count at row 1

What is wrong?

Hi,

I think it's just a typo in the code.

function watermarkImage($loaction)
{
//laster inn bildet som skal settes på bildet :)
$watermark = imagecreatefromgif("copyright.gif");
$watermark_height = imagesy($watermark);
$watermark_width = imagesx($watermark);


$image = imagecreatetruecolor($watermark_width, $watermark_height);
$image = imagecreatefromjpeg($location);

Just change watermarkImage($loaction) to watermarkImage($location)
You used $loaction instead of $location

Kieran :)

Where is $location defined?

diafol · Answer 2 · 2010-11-08T03:31:17+00:00

function watermarkImage($loaction)

This parameter cannot be accessed by $location. Good spot Kieran.
