Doubt about custom validation - pippuccio76 - 08-01-2023

hi , i have a doubt about custom validation

in controller the rule are :

Code:
my_validation_function[field_1,field_2]

and in validation class :

Code:
    public function my_validation_function(string $str,string $fields, array $data)

    {

        $mymodel = new MyModel();

        $res = $mymodel->where('field_1',$data['field1'])

                       ->where('field_2',$data['field_2])

                       ->first();

        if(!res){

            return false;

        }else{

            return true;

        }

    }

Why must I insert in controller the fields if in validation class there is every post variable ?

If your custom validation rule does not require parameters, you do not need to add any. See the "even" rule in the docs.
For your function/method, you should make the fields arg nullable by adding a ? like so:

PHP Code:
public function my_validation_function(string $str, ?string $fields, array $data) : bool 
{

} 

With that, you should be able to use the $data array from the sent form/user input.

But if i must pass a variable to the function i must insert One , tought the variabile are not the variable that i Need. Because in Array $data there are are post variable.

You can not specify anything in the rules. See how "alpha" "alpha_numeric" are created
$data is an additional, not the main source of checks
