Laravel Validator Rules in Array

The docs of the regex validation says:

"Note: When using the regex pattern, it may be necessary to specify rules in an array instead of using pipe delimiters, especially if the regular expression contains a pipe character"

https://laravel.com/docs/5.5/validation#rule-regex

But it doesn't say how to specify the rules as an array. How do I pass rules to the validator as an array?

What I'm looking for is something like:

$min = 8;
    $validator = Validator::make($request->all(), [
        'password' => array(
            'required' => true,
            'min' => $min
        )
    ]);

But that isn't working.

$request->validate([
    $request->password => 'required|min:8'
]);

Maybe I'm missing something from your example, but you should try that. There is no regex in your example.

Thanks for your reply!

There's no regex in my example. I just want to know how to pass the rules as an array.

$min = 8;
$request->validate([
    $request->password => 'required|min:'.$min
]);

Isn't clean enough for me.

Your temporary variable $min = 8 is not useful, and needs to be a string.

The "clean" code you posted will not run, I'm not sure how to help you, but I'll indulge.

$min = '8';
$request->validate([
    $request->password => ['required' => true, 'min' => $min]
]);

Maybe that's what you are after. Cheers!

Just use a double quote:

$validator = Validator::make($request->all(), [
    'password' => [
        'required',
        "min:$min"
    ]
]);

What is meant is that it is not necessary to pass the validation rule and parameters as a concatenated string. You can use an array and pass the variables pre-split, like so:

$min = 8;

$validator = Validator::make($request->all(), [
    'password' => [
        'required',
        ['min', $min],
    ],
]);

If you want to validate the regex a|b you have the problem that the rule parser does not understand required|regex:/a|b/ correctly, so you have to use the array form:

$rules = [
    'some_field' => [
        ['regex', '/a|b/']
    ]
];

Also, the array syntax is safer if your interpolated string might contain a pipe character.

I know this is an old post but it can't hurt to add something helpfull right?

The Laravel docs mean you should do the following (for multiple regex):

'postcode' => [ 'required', 'max:8', ['regex', '/^[a-zA-Z]{1,2}[0-9]{1,2} [0-9]{1}[a-zA-Z]{2}|^[a-zA-Z]{1,2}[0-9]{2,3} [a-zA-Z]{2}/'], ]

As shown above, the '|' is now applicable, and, you now have two regex that will be used in an either/or fashion.

Honestly I must credit @cschorn as there post is where I learned this. :)

Again, I know this is an old post but it can't hurt to add something helpfull right?
