Validation: Unique IF other isset/Requre if other unique

How far did you get with your custom validation rule? That's the way to go so you can do checks in the DB and allow/deny based on the results.

Thanks for the quick reply @bashy :)

I added a validateIf function(figured I could use it quite a bit) to my existing custom validators & got stuck at the point determining if the other field was NULL. The basic idea was something like:

    return [
        'number' => 'if:extension,null:unique,phones', 
        'extension' => 'if:number,unique,phones:required',
    ];

I could be way off though..

Perhaps if I first added a custom validator to determine if a field is null/empty & then call that in another custom validator.. I'll post some code shortly..

Scratch that, I'll use 'filled'

I've got

'number' => 'if:extension,null,unique,phones',

working with the following:

protected function validateNull($attribute, $value, $parameters)
{
    if($value == null || $value == ''){
        return true;
    }
    return false;
}

protected function validateIf($attribute, $value, $parameters)
{
    $other = Arr::get($this->data, $parameters[0]);
    $call = 'validate' . ucfirst($parameters[1]);
    if($this->$call($parameters[0], $other, null)){
        $func = 'validate' . ucfirst($parameters[2]);
        $parameters = array_slice($parameters, 3);
        return $this->$func($attribute, $value, $parameters);
    }else{
        return true;
    }
}

However getting

'extension' => 'not:number,unique,phones,required', // make extension required if number not unique

Or similar seems tricky. Any help, even just to clean this up would be great!

Still a bit stuck but a little explanation of the following & how best/typically it's used may help. I've seen others use similar but never in a extended validator..

$this->sometimes('number', 'unique:phones', function($blah)
{
    // ??
});

Again I'm just looking for a way to set rules for a field based on an other field passing/failing rules.

I'd think someone else would have come up with this by now, or does everyone just allow customers, user, etc to have the same phone numbers? :P

https://github.com/felixkiss/uniquewith-validator was all I needed. Rule are now simply:

    return [
        'number' => 'required|digits:10|unique_with:phones,extension',
        'extension' => 'numeric',
    ];
