Thanks for the reply. I fixed it.
It was really stupid : I put quotes around true !!

@Hulsy: Hm, without code it is difficult to say why it fails. I tested it with the following code, and it worked fine with CakePHP 1.3.6:


class Post extends AppModel {
    public $validate = array('title' => array('rule' => 'alphaNumeric', 'allowEmpty' => true));
}

Hope you still read comments on old posts…
I have the same problem with only one rule (‘alphaNumeric’) and ‘allowEmpty’. When the fields is left blank, the validation fails…
Any idea ?

@all: Thanks for your comments!

@Walker: Maybe it has changed in the meantime, at least here with 1.2.0.7043 it doesn’t work with setting it on the field.

@nate: Hm, I don’t see how this would enable complex conditional validations.

@Tarique: If possible, I try to avoid regular expressions ;-)

So that’s why it didn’t work for me.. :-)

Thanks for the tip!

Why bother – just use a regex :p

The original validation system was designed around only one rule per field, and when we went to multiple, the break-down of options followed suit. While not perfectly logical I could see this enabling certain complex conditional validations.

Thanks for the heads-up, I’m sure this would be a maddening problem I’d run in some day.

I don’t find it too illogical though. There has to be some sort of order in which the validation is done. From first to last rule sounds fine to me.
