The CI form validation class makes validating forms easy and users happy but once you have used it more than few times a little pain comes back because it is still a chore.
A while back I tried
Macigniter's lib and it was nice, then later I looked back at the code and I didn't like that I was putting html in my controllers.
On close examination what I didn't like with form validation was creating those arrays
Like this one
Code:
$config = array(
'signup' => array(
array(
'field' => 'username',
'label' => 'Username',
'rules' => 'required'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'required'
),
array(
'field' => 'passconf',
'label' => 'PasswordConfirmation',
'rules' => 'required'
),
array(
'field' => 'email',
'label' => 'Email',
'rules' => 'required'
)
),
'email' => array(
array(
'field' => 'emailaddress',
'label' => 'EmailAddress',
'rules' => 'required|valid_email'
),
array(
'field' => 'name',
'label' => 'Name',
'rules' => 'required|alpha'
),
array(
'field' => 'title',
'label' => 'Title',
'rules' => 'required'
),
array(
'field' => 'message',
'label' => 'MessageBody',
'rules' => 'required'
)
)
);
This Form_Validation extension makes it less verbose, e.g.
Code:
$config['signup'] = array(
array('username','Username','required'),
array('password','Password','required'),
array('passconf','PasswordConfirmation','required'),
array('email','Email','required')
);
$config['email'] = array(
array('emailaddress','EmailAddress','required|valid_email'),
array('name','Name','required|alpha'),
array('title','Title','required'),
array('message','MessageBody','required')
);
The extension,
application/libraries/MY_Form_validation.php
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed.');
class MY_Form_validation extends CI_Form_validation
{
function set_rules($field, $label = '', $rules = ''){
if(is_array($field) && !isset($field[0]['rules']) ) {
$keys = array('field','label','rules');
foreach($field as &$field_rules){
$field_rules = array_combine($keys,$field_rules);
}
}
parent::set_rules($field, $label = '', $rules = '');
}
}
Hope that helps someone.
