 Posted: Mon Mar 07, 2005 9:35 pm Post subject: SmartyValidate: CVS updates |
 |
|
There have been some long-coming updates to SmartyValidate in CVS, mainly a way to register your validators from the PHP side and leave the templates purely up to presentation. Without going into a lot of detail, here is a comparison of the "old" way vs. the "new" way. SmartyValidate is backward compatible, but the README has been updated to reflect the new and preferred method.
The old way:
[php:1:1401098dd1]SmartyValidate::connect($smarty);
$smarty->display('index.tpl');[/php:1:1401098dd1]
| Code: | {validate field="UserName" criteria="notEmpty" transform="trim" empty="true" halt="true" message="User Name cannot be empty"}
(form goes here) |
The new way:
[php:1:1401098dd1]SmartyValidate::connect($smarty);
SmartyValidate::register_validator('user','UserName','notEmpty',true,true,'trim');
$smarty->display('index.tpl');[/php:1:1401098dd1]
| Code: | {validate id="user" message="User Name cannot be empty"}
(form goes here) |
Basically you scrap all of the tags from the template except message, append and assign tags, and a new id tag is introduced, being the validator id given at registration. (Yes, you can make the id the same as the field name to make things easier, but if you have multiple validators on the same field they must have unique ids.)
For validators that act on multiple fields, you pass all the field names separated by colons:
[php:1:1401098dd1]SmartyValidate::register_validator('checkpass','pass1:pass2','isEqual');[/php:1:1401098dd1]
| Code: | | {validator id="checkpass" message="passwords must be equal"} |
Each additional field is passed to the validate function as field2, field3, etc.
Please test and give me your feedback. I've done quite a bit myself, but extra help is always welcome

Thanks for the update Monte -- I haven't checked the cvs in awhile. I'm certainly in the camp that thinks this is the proper direction to take. As it happens, I have a new project that I just started which may be able to make use of some of this goodness so I'll likely be checking in at some point with comments regarding my experiences.
Thanks, as always! |

I'm using the new method from CVS but have found some issues with register_validator().
It seems to dislike being called on every invocation and your examples only call the register_validator() function width _POST is empty.
The is_registered_validator() returns $_x = 0 when a validator at index 0 has been found, however 0 translates to FALSE...
This is with PHP-5.0.4-RC1...

Hmm, the register_validator() command unregisters, then re-registers a validator if you try to register an already registered validator. What isn't working? Maybe it should just return false if it is already registered.
As for is_registered_validator(), it returns the indexed position if it finds one. You would have to look for false explicitly:
if(SmartyValidate::is_registered_validator('blah') !== false) { } |
