Re: Validation rule with or
I finished a quick mockout of the code for my article. I am still adding the finishing touches, but you can get the idea. The one main change I hope to make by the time this gets read is to handle all the logic upfront, and only once, instead of for each field. So here it is.. Validating dependent fields in CakePHP... THe dreaded OR rule http://edwardawebb.com/programming/php-programming/cakephp/validating-optional-fields-cakephp-dreaded-scenario On Feb 11, 11:07 am, WebbedIT wrote: > Sounds like a more elegant approach than mine .. look forward to the > article :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "CakePHP" group.

Re: Validation rule with or
Henrik:
Seems like a pretty common need doesn't it. The solution is pretty
simple.
You call the same validation rule for every related field.
$validate=
array(
'field1'=>array('rule'=>'dependentFields'),
'field2'=>array('rule'=>'dependentFields')
)
Then the method
function dependenFields()
{
$return=false;
logic based on fields to do the comparison etc.
// if dependencies pass
$return=true;
//otherwise unique errors
$return="You provided your Company Name, but forgot Phone"
}
and those messages ()if your logic is right) will show only under the
failing boxes.
I will post the full details in an article on my site which is not
quite complete (and I am at work right now :/). Check back tonight
perhaps.

Re: Validation rule with or
I do not believe there are any built-in validation rules to do this so
you need to specify your own custom validation method such as:
function __validateFieldDependancy($data, $field1, $field2) {
// return false if ThisModelName.field1 and ThisModelName.field2 are
empty
return empty($this->data[$this->name][$field1']) && empty($this->data
[$this->name][$field2]) ? false : true;
}
This would go in your model and would be called by the following
validation rule:
var $validate = array(
'field_name' => array(
'rule' => array('__validateFieldDependancy', 'fieldName1',
'fieldName2'),
'message' => 'Your error message'
)
)
Not sure if it is neccessary to make this method private (named
starting with double underscores) but thought it was more secure to do
so.
There is probably a better way to test both fields are empty ... happy
for people to better educate me on this as I'm self-taught with PHP.
If you are going to use this type of validation rule regularly across
multiple models it may be worth aking it available to all models by
placing it in /app/app_model.php
Hope this helps,
Paul (WebbedIT)

Validation rule with or
I have a form where you have to enter either ("firstname" AND
"lastname" AND "phone") OR ("companyname" AND phone")
how do I make a validate rule like that?
