I'm going to cut out a bit of this to make it simpler, but here is a
section of the code behind my users->signup page, and the
corresponding validation model.
VIEW:
create('User', array('action' => 'signup')); ?>
input('User/username', array('between' => ':
', 'id' => 'focus')); ?>
input('User/email', array('between' => ':
')); ?>
end('Register'); ?>
and:
MODEL:
var $validate = array(
'username' => array(
'alphanumeric' => array(
'rule' => array('custom', '/[a-z0-9\_\-]$/i'),
'required' => true,
'message' => 'Username must be a-z, 0-9, plus "_", "-", " "'
),
'between' => array(
'rule' => array('between', 5, 30),
'message' => 'Between 5 and 30 characters'
),
'checkUnique' => array(
'rule' => array('checkUnique', 'username'),
'message' => 'Username is in use. Choose another.'
)
),
'password' => array(
'rule' => array('minLength', '6'),
'message' => 'Minimum 6 characters'
),
'email' => array(
'valid' => array(
'rule' => array('email', true),
'message' => 'Please use a valid E-Mail address'
),
'checkUnique' => array(
'rule' => array('checkUnique', 'email'),
'message' => 'E-mail is already being used. Choose another.'
)
),
)
/*function to check that
entered data is not currently present in the database*/
function checkUnique($data,
$fieldName)
{
$valid = false;
if(isset($fieldName) && $this->hasField($fieldName))
{
$valid = $this->isUnique(array($fieldName => $data));
}
return $valid;
}
The first username rule "alphanumeric" is a custom rule which searches
for letters, numbers, dashes, underscores, and spaces as valid
characters, and if anything else is present, throws a validation
error.
The second username rule "between", checks for both minimum and
maximum values. To change it to maxValue only, you would change it to
this:
'between' => array(
'rule' => array('MaxLength', 30),
'message' => 'Between 5 and 30 characters'
)
The third username rule, 'isUnique', simply uses the isUnique()
function in CakePHP 1.2 to find out if the entered username is already
in use or not.
The password field simpy has a minimum length requirement.
The email rule uses the builtin email verification validation
function, and the isUnique() funciton to check for pre-used emails
again.
Hope this helps! If you (or anyone else) has any questions, feel free to
ask!
