I'm using a validates function in a model in order to validate image
uploads. I want to validate the filetype, and also make it required.
I know cake has built in validation for these, but I could never get
it to work. The image upload component I am using uses an array,
accessible via $this->data['Img']['pic'].
The problem I am having, is that the /add/ function works great, but
when I use the image field (Img.pic) on another function (/
edit_image/) the validation function isn't applied.
Here is the model code:
function validates()
{
$image = $this->data['Img']['pic']['name'];
// Grab the file extension:
$path = pathinfo($image);
$filetype = $path['extension'];
if(!empty($image)) {
if (($filetype != 'JPG') && ($filetype != 'jpg') && ($filetype
!=
'GIF') && ($filetype != 'gif') && ($filetype != 'JPEG') && ($filetype !
= 'jpeg'))
{
$this->invalidate('Img.pic');
}
}
else {
$this->invalidate('Img.pic');
}
$errors = $this->invalidFields();
return count($errors) == 0;
}
Is there something I have to include in the controller to make the
above happen automatically?
I would appreciate any guidance on this, I can include more code if
requested.
Thanks in advance.
