Validate more than one field

[makroxyz]

I'm using precognition form in a wizard. Every step has some properties of that form. I'd like, when press next, to validate only fields in the current step.

Is there a way to do it?

@driesvints can I open a feature request for form.validate()? I think it could be useful to let pass a string or an array of strings with field(s) to validate

You can always attempt a PR to see if Taylor would accept it 👍

@makroxyz you can use the form.touch and form.touch helpers to modify what is supposed to be validated.

For example, when attempting to go to the next page you might do the following...

form.touch(['name', 'email', 'address']).validate()

This will validate all the fields, even if they have not been interacted with by the user.

If you want to exclude previously validated inputs you could use the touch helper...

form.touch(['name', 'email', 'address']).validate()

Thank you! That was one of the things I wanted since I saw Laracon.

form.touch has solved one issue for me, but how would I then run a callback function to wait until the form has finished validating the given fields?

For example my code is like this, but I need to wait until the validation has finished before emitting the event.

function nextStep() {
    form.touch(["name", "email", "password", "password_validation"]).validate();

    emit("next");
}

It would be great to know this, I also have this problem.

We will be adding the ability to detect individual validation responses. Follow along in https://github.com/laravel/precognition/issues/59
