how can create a Custom Validation
How Do I?
in Expression engine BuildIn validation rules are in /system/ee/EllisLab/ExpressionEngine/Service/Validation/Rule/xxxx.php
If im need a custom validation(query on channel model)
where put the file for this?
I’m a bit unclear on what you’re going for. Is this on a form submission? On publish and/or the frontend channel form? Is it a new custom field type or adding some extra validation to an existing field type?
Backend, Channel Form on FrontEnd
Walk me through what you want to do a bit more. Is there a specific field you want to require additional validation? Just for one field or a whole field type?
For example im have a custom text field type, in a form channel on FrontEnd, in this field im save an User ID(From a DropDown List), im need create a custom validation rule, this validation rule work like
$user_ID=$_Post[“user_id”];//Or any standar method
Here run Query to Users Models, if user Exist Return True, if User dont Exist return Error
Other Example, im Have a Text Field called “DNI” The Chilean DNI its validated By Module 11 Algorithm Its not a simple Regex Validation, need Calculate Values and return True or Error
