Heres the problem
I want to require a field (litters_per_year) only if another field that is a checkbox is checked. When I do this, cake is trying to force me to put a value into the field and I don't know why. I have tried setting required & allowEmpty to false & true respectively, but then my custom rule does not run.
Heres the code
NOTE: The details of the following code aren't that important - they are here to provide a scenario.
I have the following code in my VIEW which works fine:
echo $this->Form->input('litters_per_year', array(
'label' => 'Litters per year (average)'
));
I have the following code in my MODEL's public $validate:
'litters_per_year' => array(
'isNeeded' => array(
'rule' => array('isNeeded', 'litters_per_year'),
'message' => 'Please enter the litters per year average'
)
)
which is calling the custom validation method
public function isNeeded($field) {
// Check if a checkbox is checked right here
// Assume it is not... return false
return false;
}
It returns false for simplicity to solve this issue.
Let's assume that the checkbox field is named 'the_checkbox'.
