Earlier this week, I was working on a project where I needed to validate two dependent fields.
<?php echo input('office', array('type' => 'select', 'options' => $nd[0])); ?> <?php echo input('office_other', array('maxlength' => '255', 'size' => '35', 'label' => 'Other Office')); ?>
The “office” field is a select (drop down box) from my data array(). What I needed is to be able to add another data from a field and name it as “office_other” where it would initially capture and re-list again new offices if it does not exist.
I found an article on the web that seems to relate on this similar goal here (thanks).
Here’s my code for this project:
Model, where rule validation should be imposed.
var $validate = array( 'office' => array( 'notempty' => array( 'rule' => array('notempty'), 'message' => 'Please select your office.', 'allowEmpty' => false, 'required' => true, ), ), 'office_other' => array( 'validateoffice' => array( 'rule' => array('validateOtherOffice', 'office_other'), 'message' => 'Kindly enter new office code.'), ),
The key here is to add a custom validation process, mine is the validateOtherOffice() function.
function validateOtherOffice($check) { $valid = false; //debug($check); //debug($this->data['Account']); if ($this->data['Account']['office'] == 'office_new') { if (empty($check['office_other'])) { $valid = false; } else { $valid = true; } } else { $valid = true; } return $valid; }
Now my application was able to validate two dependent fields.
is this the best way?
