 |
|
Hi, is it possible for a validation to only occur when another field is not empty?
For example: If field 1 is not empty, the validation for field 2 must occur.
Else, if field 1 is empty, the validation for field 2 should not occur.
Thanks, |

| You can create a custom validator to do whatever you want. There isn't one that comes with SmartyValidate to do this specifically. |

Hi,
I am facing a problem when trying to do more than one validation on username and i have the following:
register.php
| Code: |
SmartyValidate::register_validator('v_username1', 'username', 'notEmpty', false, false, 'trim');
SmartyValidate::register_validator('v_username2', 'username', 'isValidUser', false, false, 'trim');
|
and regsiter.tpl
| Code: |
{validate id="v_username1" message="username cannot be empty"}
{validate id="v_username2" message="username already exists"} |
And the custom validate_criteria.isValidUser.php
| Code: |
function smarty_validate_criteria_isValidUser($value, $empty, &$params, &$formvars){
if(strlen($value) == 0)
return $empty;
global $userlib;
if($userlib->UserExists($value) ) {
//if user exists, UserExists will return true, we'll return false to smartyvalidate
// UserExists function tested to be working correctly
return false;
}
return true;
}
|
If i submit any username or currently existance username, it work fine.
The problem i have is, if i start the form by submitting an empty username filed, i got both the error msg of username cannot be empty (v_username1) and username already exist (v_username2). Any idea where i went wrong? |

| you need "true" for the halt parameter on the first one. |

This would mean no further check or error will be display if username field is empty. I was thinking of displaying all the different field error messages at one go irregardless of empty or filled username. Guess i will adapt the halt if empty option. thanks.

If you want to collect all the errors, use append.
{validate ... append="foo"}
{validate ... append="foo"}
then loop over $foo |
