I have two fields: Email and Telephone
i want to create a validation where one of two fields are required and if one or both fields are set, it should be the correct Format.
I tried this, but it doesnt work, i need both though
public static array $createValidationRules = [
'email' => 'required_without:telephone|email:rfc',
'telephone' => 'required_without:email|numeric|regex:/^\d{5,15}$/',
];
It is correct that both fields produce the required_without error message if both are empty. This error message clearly says that the field must be filled if the other is not. You may change the message if needed:
$messages = [
'email.required_without' => 'foo',
'telephone.required_without' => 'bar',
];
However, you must add the nullable rule, so the format rules don't apply when the field is empty:
$rules = [
'email' => ['required_without:telephone', 'nullable', 'email:rfc'],
'telephone' => ['required_without:email', 'nullable', 'numeric', 'regex:/^\d{5,15}$/'],
];
Furthermore: It is recommended writing the rules as array, especially when using regex.

I have an array of values that I send together with other fields in a form to laravel.
The array contains a role_id field and a status field, the status can be I (Insert) U (update) D (Delete). When I validate the values in the array I want it to skip the ones where the status equals D. Otherwise I want it to validate.
private function checkValuesUpdate($userid = null)
{
return Request::validate(
[
'displayname' => 'required',
'username' => 'required',
'email' => ['nullable', 'unique:contacts,email' . (is_null($userid ) ? '' : (',' . $userid ))],
'roles.*.role_id' => ['exclude_if:roles.*.status,D', 'required']
]
);
}
I can't seem to get it to work. I've been searching all over the place for functional code as well as the Laravel documentation. But no luck so far. Has anybody ever done this?
Your problem comes from a misunderstanding of the exclude_if rule. It doesn't exclude the value from validation, it only excludes the value from the returned data. So it would not be included if you ran request()->validated() to get the validated input values.
According to the documentation, you can use validation rules with array/star notation so using the required_unless rule might be a better approach. (Note there's also more concise code to replace the old unique rule, and I've added a rule to check contents of the role status.)
$rules = [
'displayname' => 'required',
'username' => 'required',
'email' => [
'nullable',
Rule::unique("contacts")->ignore($userid ?? 0)
],
'roles' => 'array',
'roles.*.status' => 'in:I,U,D',
'roles.*.role_id' => ['required_unless:roles.*.status,D']
];
For the below code , i don't want the password field to have the same value of currentPassword field. The desired output is to show some validation error like "password & currentPassword canot be the same" ,when one types same value for both password & currentPassword fields. To be more precise, it should work in opposite of the rule - same does.
$validator = Validator::make(
$request->all(),
[
'currentPassword' => 'required',
'password' => 'required|min:6|confirmed',
]
);
You would expect the rule to be named "NotSame", but it is not. Instead the validation rule is called different.
'password' => 'different:currentPassword'
I'm trying to create a user update validation through form, where I pass, for example 'password'=>NULL, or 'password'=>'newone';
I'm trying to make it validate ONLY if it's passed as not null, and nothing, not even 'sometimes' works :/
I'm trying to validate as :
Validator::make(
['test' => null],
['test' => 'sometimes|required|min:6']
)->validate();
But it fails to validate.
Perhaps you were looking for 'nullable'?
'test'=> 'nullable|min:6'
Though the question is a bit old, this is how you should do it. You dont need to struggle so hard, with so much code, on something this simple.
You need to have both nullable and sometimes on the validation rule, like:
$this->validate($request, [
'username' => 'required|unique:login',
'password' => 'sometimes|nullable|between:8,20'
]);
The above will validate only if the field has some value, and ignore if there is none, or if it passes null. This works well.
Do not pass 'required' on validator
Validate like below
$this->validate($request, [
'username' => 'required|unique:login',
'password' => 'between:8,20'
]);
The above validator will accept password only if they are present but should be between 8 and 20
This is what I did in my use case
case 'update':
$rules = [
'protocol_id' => 'required',
'name' => 'required|max:30|unique:tenant.trackers'.',name,' . $id,
'ip'=>'required',
'imei' => 'max:30|unique:tenant.trackers'.',imei,' . $id,
'simcard_no' => 'between:8,15|unique:tenant.trackers'.',simcard_no,' . $id,
'data_retention_period'=>'required|integer'
];
break;
Here the tracker may or may not have sim card number , if present it will be 8 to 15 characters wrong
Update
if you still want to pass hardcoded 'NULL' value then add the
following in validator
$str='NULL';
$rules = [
password => 'required|not_in:'.$str,
];
I think you are looking for filled.
https://laravel.com/docs/5.4/validation#rule-filled
The relevant validation rules are:
required
sometimes
nullable
All have their uses and they can be checked here:
https://laravel.com/docs/5.8/validation#rule-required
if you want validation to always apply
https://laravel.com/docs/5.8/validation#conditionally-adding-rules
if you want to apply validation rules sometimes

if you want your attribute to allow for null as value too
I am having a form where i am having title, body, answers[][answer] and options[][option].
I want atleast one answer must be selected for the given question, for example:
i have ABC question and having 5 options for that question,now atleast one answer must be checked or all for given question.
Efforts
protected $rules = [
'title' => 'required|unique:contents|max:255',
'body' => 'required|min:10',
'type' => 'required',
'belongsto' => 'sometimes|required',
'options.*.option' => 'required|max:100',
'answers.*.answer' => 'required',
];
But this is not working. i want atleast one answer must be selected.
Please help me.
The problem is that on $_POST an array filled with empty strings will be passed if no answer is selected.
$answers[0][0] = ''
$answers[0][1] = ''
$answers[0][2] = ''
Hence the following will not work since array count will be greater than zero due to the empty strings:
$validator = Validator::make($request->all(), [
'answers.*' => 'required'
]);
The easiest way to solve this is to create a custom Validator rule by using Laravel's Validator::extend function.
Validator::extendImplicit('arrayRequireMin', function($attribute, $values, $parameters)
{
$countFilled = count(array_filter($values));
return ($countFilled >= $parameters[0]);
});
And then call it in your Validation request:
$validator = Validator::make($request->all(), [
'answers.*' => 'arrayRequireMin:1'
]);
The magic happens in array_filter() which removes all empty attributes from the array. Now you can set any minimum number of answers required.
Validator::extendImplicit() vs Validator::extend()
For a rule to run even when an attribute is empty, the rule must imply that the attribute is required. To create such an "implicit" extension, use the Validator::extendImplicit() method:
Laravel's validation docs
Try this,
'answer.0' => 'required'
it will help you. I think.
I have two fields:
QQ
Email
How do I set up a Validator object so that one of these fields must be filled? It doesn't matter which.
$messages = array(
'email.required_without:qq' => Lang::get('messages.mustenteremail'),
'email.email' => Lang::get('messages.emailinvalid'),
'qq.required_without:email' => Lang::get('messages.mustenterqq'),
);
required_without should work.
It means that the field is required if the other field is not present. If have more than two fields and only one is required, use required_without_all:foo,bar,...
$rules = array(
'Email' => 'required_without:QQ',
'QQ' => 'required_without:Email',
);
In the example above (given by lucasgeiter) you actually only need one of the conditions not both.
$rules = array(
'Email' => 'required_without:QQ'
);
If you have both rules then filling neither in will result in TWO error messages being displayed. This way it will check that at least one field is filled in and will only display one error message if neither are filled.
Laravel >= 8.32 only support.
Both (mobile or email) are presented simultaneously -> throw an error.
Both (mobile or email) is not present simultaneously -> throw an error.
Allowed
Only one parameter can be allowed.
'email' => [ 'prohibited_unless:mobile,null,','required_without:mobile','email', 'max:255', ],
'mobile' => [ 'prohibited_unless:email,null','required_without:email', 'digits_between:5,13', 'numeric' ],
EDIT: You can also use prohibits:email and prohibits:mobile in combination of required_without:... rule
