You shouldn't need to do that. The process is
you call Model::save() Model::save calls validates validates calls invalidFields invalidFields iterates the validate array and set validationErrors via invalidate (in your ValidFunc you make a call to invalidate therby also setting validationErrors) invalidFields returns validationErrors to validates validates makes sure that validationErrors count is 0 validates returns false to save wich then returns false to your if ($model->save()) Then all happens as normal :- validationErrors is passed onto view in controller::render (line 639)) as long as the Model is one of the $uses. If you are instatiating the Model yourself it wont forward on the validationErrors Geoff -- http://lemoncake.wordpress.com On Jun 28, 3:22 pm, phpjoy <[EMAIL PROTECTED]> wrote: > works like a charm.. here's the final code: > > var $validate = array( > 'directory' => array('rule' => 'ValidFunc') > ); > > function ValidFunc($value) { > $this->data['ModelName']['fieldname']='new' .$value; > case 1: $this->invalidate('fieldname', 'message1'); return true; > case 2: $this->invalidate('fieldname', 'message2'); return true; > } > > now here's the magic trick, in order to make it visible in the form in > the view i should..: > $this->data = $this->ModelName->data; > otherwise it doesn't get changed in the controller and then displayed > in the view. > > is there a way to change it from the model itself? > > On Jun 28, 1:05 am, francky06l <[EMAIL PROTECTED]> wrote: > > > Yes, nice hack somehow :-) > > Thanks Geoff > > > On Jun 28, 12:56 am, Geoff Ford <[EMAIL PROTECTED]> wrote: > > > > Just took at look at the code and your right franky, after you return > > > false from your custom function invalidFields() then calls $this- > > > > >invalidate() itself overwriting the message you just wrote. > > > > However this is not the case if you return true. > > > > This may be a bit "wrong" but you can get around this like so > > > > function ValidFun($ruleParams){ > > > $fieldName = array_keys($ruleParams); > > > $fieldName = $fieldName[0]; > > > if ($conditions){ > > > // all validation passed > > > } else { > > > // validation failed > > > $this->invalidate($fieldName, 'Your Error Message'); > > > } > > > > return true; > > > > } > > > > By always returning true invalidFields() will not set the error > > > message itself, but the Model::validationErrors will still contain the > > > invalid field with your error message and and so Model::validates() > > > will return the correct value of false. > > > > On Jun 28, 8:45 am, francky06l <[EMAIL PROTECTED]> wrote: > > > > > I am not sure that will work (I might be wrong) but it seems to me > > > > that the model->invalidate is called after your validFunc returning > > > > false (this call will oerwrite your message).
