Once run check rule if another passes in Laravel 5
I have the following rules in my request:
Validator::extend('valid_date', function($attribute, $value, $parameters)
{
$pieces = explode('/', $value);
if(checkdate($pieces[1], $pieces[0], $pieces[2])) {
return true;
} else {
return false;
}
});
return [
'first_name' => 'required',
'last_name' => 'required',
'email' => 'required|email|unique:users,email',
'dob' => 'required|regex:/[0-9]{2}\/[0-9]{2}\/[0-9]{4}/|valid_date',
'mobile' => 'required',
'password' => 'required|confirmed'
];
For the dob field, I want the valid_date rule to fire if the regex validation returns true. If the regex check returns false, then there is no point in doing the valid_date check and if there is no / present in the value, then it will be wrong when it tries to explode on /
Is there a way to conditionally add rules if another rule is valid?

You can use the method sometimes () .
$v = Validator::make($data, [
'first_name' => 'required',
'last_name' => 'required',
'email' => 'required|email|unique:users,email',
'dob' => 'required|regex:/[0-9]{2}\/[0-9]{2}\/[0-9]{4}/',
'mobile' => 'required',
'password' => 'required|confirmed'
]);
$v->sometimes('dob', 'valid_date', function($input)
{
return apply_regex($input->dob) === true;
});
valid_date
will fire if apply_regex($input->dob)
true. Note apply_regex
if your custom function that evaluates the valuedob
