Modify the updoad class to check image orientation?

[eluser]chefnelone[/eluser]
Hello,

I need to do some change to the upload class to check on the uploaded image orientation.

I´d create the parameter:

Code:

function initialize($config = array())
{
  $defaults = array(
        
    'orientation'            => 'landscape', // lanscape, portrait
     .....
  );
}

The class should check if the uploade image orientation match the preference, and if not should show the error with:

Code:

if ( ! $this->is_allowed_orientation())
        {
            $this->set_error('upload_invalid_orientation');
            return FALSE;
        }

But then I found complicate to make the rest...
This week I´ll be posting what I do to get some help

Thanks

One the image has been uploaded, check if the width is longer than the length for landscape, and if the length is longer than the width for portrait.

Code:

$im = @imagecreatefromjpeg('path/to/your/uploaded/image');

if(imagesx($im) > imagesy($im))
{
    //landscape
}
elseif(imagesx($im) < imagesy($im))
{
    //portrait
}
else
{
    //default
}

thanks, I think that your code is to put in the controller, not in the upload class. Am I right?

Yes, in the controller or, as a function, in the extended upload class.
