I have some hard times with Laravel Rules (importing csv file).
I'm trying to use the Rule::unique function but when another field is not empty, for example:
public function rules(): array
{
return [
'code' => ['required', 'string', Rule::unique('product_gift_cards', 'code')],
'pin' => ['nullable'],
'sequence_number' => ['nullable']
];
}
So this code, should be unique only when sequence_number is not filled. When sequence_number is filled with something, the code should not be unique. I have deleted the unique index in the database, so it will work if I write is as needed, any suggestions?
These are the validation rules in Laravel: https://laravel.com/docs/9.x/validation#available-validation-rules
Sadly there's no unique_if rule here.
One possible solution here is you have to validate it manually. You check if the input has file uploaded using $this->hasFile('sequence_number').
$code_rules = ['required', 'string'];
// Check if sequence_number is NOT uploaded
if (! $this->hasFile('sequence_number')) {
$code_rules[] = Rule::unique('product_gift_cards', 'code');
}
return [
'code' => $code_rules,
'pin' => ['nullable'],
'sequence_number' => ['nullable']
];

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']
];
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.
Currently I have working validator in my Request folder
public function rules()
{
return [
'ahiTitle' => ['string', 'max:255'],
'ahiDesc' => ['string'],
'ahiDate' => ['required'],
'ahiType' => ['required', 'string', 'max:255'],
'attachment' => ['required','image','mimes:jpeg,png,jpg,gif,svg','max:2048']
];
}
for the field of ahiType I have 2 different expected values to be received
COURSE AND FACILITY
I'm trying to do if the rules finds out that the value of ahiType is FACILITY
This will rule out that the field ahiDate is required but if the ahiType has the value of COURSE
the ahiDate should be nullable means not required. Is that possible?
Note: I can filter it using jquery validation but I just want to use validator since all my validations are stated in here.
"ahiDate" => "required_if:ahiType,==,FACILITY"
I am working on a Laravel project and I have the following problem related to validation.
In the past I created this validation rules (related to a new user registration form):
$rules = [
'name' => 'required',
'surname' => 'required',
'login' => 'required|unique:pm_user,login',
'email' => 'required|email|confirmed|unique:pm_user,email',
'pass' => 'required|required|min:6',
'g-recaptcha-response' => 'required|captcha',
];
In particular this rules array contains this rule:
'login' => 'required|unique:pm_user,login',
it seems to me that this last rule check if the inserted login doesn't yet exist into the pm_user table (so it ensure that not exist a row of the pm_user table having the same inserted value into the login column).
Is it? Correct me if I am doing wrong assertion.
If it work in this way now my problem is how to do the opposite thing in another set of validation rule.
In particular I have this other array of rule (defined into a class extendingFormRequest:
public function rules() {
return [
'email' => 'required|email',
'token' => 'required',
];
}
In particular I have to ensure that into the pm_user table yet exist a record having the value of the column named email that is the same of the emai field of the request.
How can I change this request to perform this validation rule?
Laravel 5.4 already has a built in validation rule for this called exists.
https://laravel.com/docs/5.4/validation#rule-exists
I think you are looking for:
'email' => 'required|email|exists:pm_user,email'
These are my rules in my class:
class AppointmentsController extends Controller
{
protected $rules = [
'appointment' => ['required', 'min:5'],
'slug' => ['required', 'unique:appointments'],
'description' => ['required'],
'date' => ['required', 'date_format:"Y-m-d H:i"'],
];
This is in the laravel official docs:
Sometimes, you may wish to ignore a given ID during the unique check.
For example, consider an "update profile" screen that includes the
user's name, e-mail address, and location. Of course, you will want to
verify that the e-mail address is unique. However, if the user only
changes the name field and not the e-mail field, you do not want a
validation error to be thrown because the user is already the owner of
the e-mail address. You only want to throw a validation error if the
user provides an e-mail address that is already used by a different
user. To tell the unique rule to ignore the user's ID, you may pass
the ID as the third parameter:
'email' => 'unique:users,email_address,'.$user->id.',user_id'
I tried using this in my rules:
'slug' => ['required', 'unique:appointments,id,:id'],
This indeed ignores the current row BUT it ignores it completely. What I want to accomplish is, I want it to ignore the current row only if the slug is unchanged. When it is changed to something that is already unique in another row, I want it to throw an error.
The Unique validator works like that
unique:table,column,except,idColumn
So in your case, you can do it like that:
Get the id you want to validate against, you can get it from the route or with any other way that works for you; something like that
$id = $this->route('id');
'slug' => ['required','unique:appointments,slug,'.$id],
For example we need to update contact info into Users table.
In my model User I created this static method:
static function getContactDataValidationRules( $idUserToExcept ) {
return [
'email' => 'required|email|max:255|unique:users,email,' . $idUserToExcept,
'pec' => 'required|email|max:255',
'phone' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:8|max:20',
'mobile' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:8|max:20',
'phone2' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:8|max:20',
'recovery_email' => 'required|email|max:255',
];
}
and in my UsersController, into the method that update User I've:
$id = $request->input('id');
$request->validate(User::getContactDataValidationRules( $id ));
