[SOLVED] Calling on another files functions

[adam291086]

I am calling a function from one php doc to another. Currently i get the error message

 

 

Fatal error: Call to undefined method: gallerysizer->loadimage() in /homepages/12/d214897219/htdocs/adam/create_thumbnails.php on line 20

 

Can anyone see the difference between these two bits of text

 

if($thumb->loadImage())

 

and

 

function loadImage()
{
        $this->img = null;
        $extension = strtolower(end(explode('.', $this->image_path)));
        if ($extension == 'jpg' || $extension == 'jpeg'){
            $this->img = imagecreatefromjpeg($this->image_path);
        } else if ($extension == 'png'){
            $this->img = imagecreatefrompng($this->image_path);
        } else {
            return false;
        }

 

If there is no difference whats wrong?

There is no difference (and besides the method name there isn't much to compare...). The error simply states that the object "gallerysizer" does not have a "loadImage()" method declared inside it. Perhaps there's a typo somewhere inside the gallerysizer class?

Heres all the code from the GallerySizer file. Thanks for the help
