How to validate a date, or a string.

Hi!

I have a field that is suppost to be a date. But now i have decided to also have the ability to enter a string. Why you might ask? Because that I store some data of a specifik product both in the US, Europe and Japan. And it would be nice to actually see if that product hasent been release in that region.

        $request->validate([
            'europe_release' => 'nullable|date_format:Y-m-d'
        ]);

So how can i add the ability to add the option to enter "not released" with this date_format?

Thanks!

I would have not released as a separate field, maybe a boolean.

Well, the dater_format key only supports date formats and no other formats. If you want to support this I would recommend you to create a custom Rule and use that

Documentation: https://laravel.com/docs/8.x/validation#custom-validation-rules

You can use the date_format rule as a base for your own rule, but this way you can add your own functionality to it ;)

The suggestion of @jlrdw is also good, to use a different field to make this work and hide the date field in the UI

is your string only "not released"? If so, what about a simple if statement if the date is blank = string "not released"

@gillesdeb Yeah good input! But the date could also be unknown, that why.

But i think i will go with the boolean option.

A checkbox with the validation of required_unless:anotherfield,value,... and also for the date_format will have the required_unless:anotherfield,value,.... Or am i wrong?
