best way to add validation functions - El Forum - 06-19-2008
[eluser]skattabrain[/eluser]
hello,
i've been trying to get my validation callbacks into some sort of single file so i can reuse the fucntions within this project as well as others.
i've been adding these validation functions to a helper file, but things don't seem to work right. is there a better way than to add these fucntions in a helper?
should i extend the validation class instead?
i haven't extended ci in anyway yet ... trying to get the most out of a vanilla install for easy upgrading etc ...

I think extending the validation class is the best way to centralize callbacks:
So I could have a username_duplicate_check callback function included in MY_Validation.php, then use it in the validation rules:
Code:
$rules['username'] = 'trim|required|username_duplicate_check';I have been giving some thought about where to centralize rules for fields used in multiple controllers; I think a config file maybe the place to do it or maybe even putting it MY_Validation and overriding it if needed.
