Validation callback issue - El Forum - 06-24-2008

Hi,
I have something like this in my controller:
...
$rules['parentid'] = "callback_parental_check";
...
function parental_check($parent)
{
}
It's working fine but I need to pass another parameter for parental_check function to compare it with $parent variable. How can this be done?
Thanks.

If you look at the validation library and other callbacks, you notice how some use smth like callback[variable]. When I had a look at the library, I noticed the functions off those callbacks had $variable set as the second parameter... Not sure if it's that easy, but it won't hurt to try, won't it?

I don't get it. How should my code look like?
Thanks.

By the way, I'm not even able to set a var at the beginning of the Controller, like
var blablabla;
The callback function can't see it

Hi...
It's really easy...
Just do:
Code:
$rules['parentid'] = 'callback_parental_check[blah]';
function parental_check($parent, $variable)
{
// $variable == 'blah' now, because it's been passed in!
// Insert code for doing the check or whatever
}Hope that helps!
