[Vtigercrm-developers] Field Validator classes?

[Alan Lord]

I was looking to port a mod I have made to a validator in the 
modules/Vtiger/resources/validator/FieldValidator.js file from vtiger 6 
to vtiger 7.

The jQuery class style of validator seems to have disappeared completely.

Looking in various fields in v7 I see nothing in the validator json 
array but I do see various "data-rule..." attributes.

These seem to be set using Javascript, but I can't find where the 
validation test itself is carried out.

For example, in a phone field there is a data attribute:

> data-rule-phone="true"

But if I grep the source for "rule-phone" I find nothing. (Grepping for 
"phone" is pretty pointless as it returns so many results)

An email field has the following attributes:

> data-rule-email="true"
> data-rule-illegal="true"

I found this email rule referenced in a few places using grep including 
in layouts/v7/modules/Vtiger/resources/validation.js


In the same file I did find a validator for "phone" - but it does 
nothing (also note it has the wrong error message which isn't even 
translated):

> jQuery.validator.addMethod("phone", function(value, element, params) {
> 		try {
> 			return true;
> 		} catch(err) {
> 			console.log(err);
> 			return false;
> 		}
> 	}, jQuery.validator.format("Please enter the correct date")
> );

But I think I can do something with this now. So my question is really 
about the jQuery.validator.addMethod call.

Looking at the jQuery.validator documentation I can't see anything like 
a $.validator.deleteMethod(name); type call. So is it possible to 
extend/override from a custom Javascript library or do I have to modify 
the validation.js file?

TIA
