Multiple form validators

hus_hmd · May 10th 2020

It would be handy if we can use multiple form validators on a single input field.

A use-case I'm currently dealing with is checking whether a member's phone number is unique and whether it is a valid phone number. While it is possible to perform all checks with a single validator function, it doesn't seem to be possible to have different error messages for each validation type:

HTML

<perch:error for="phone" type="helper">
A single error message for all custom validation types
</perch:error>

Perhaps the helper attribute could have a suffix to specify the type:

HTML

<perch:input id="phone"
type="text"
required
helper-unqiue="MyApp_Validators::is_phone_unique"
helper-format="MyApp_Validators::is_phone_valid"
>
<perch:error for="phone" type="helper-unqiue"></perch:error>
<perch:error for="phone" type="helper-format"></perch:error>
<perch:error for="phone" type="unqiue"></perch:error>
<perch:error for="phone" type="format"></perch:error>
