Laravel array validation in Form Request - php

I can't validate a field, which contains array elements, in Form Request class.
Rules method:
public function rules()
{
return [
"state" => 'required',
"state.0" => 'required',
"state.*" => 'required',
];
}
There is an array in request->all()
"state" => array:1 [
0 => ""
]
Zero element is empty. But validation is successful.
What am I doing wrong?

In order to handle the dynamic fields, you will need to loop through all the posted "items" and add a rule for each.
Here is an updated method demonstrating this:
public function rules() {
$rules = [
'state' => 'required',
];
foreach($this->request->get('state') as $key => $val) {
$rules['state.'.$key] = 'required';
}
return $rules;
}

How to validate array in Laravel?

I try to validate array POST in Laravel:
$validator = Validator::make($request->all(), [
"name.*" => 'required|distinct|min:3',
"amount.*" => 'required|integer|min:1',
"description.*" => "required|string"
]);
I send empty POST and get this if ($validator->fails()) {} as False. It means that validation is true, but it is not.
How to validate array in Laravel? When I submit a form with input name="name[]"
Asterisk symbol (*) is used to check values in the array, not the array itself.
$validator = Validator::make($request->all(), [
"names" => "required|array|min:3",
"names.*" => "required|string|distinct|min:3",
]);
In the example above:
"names" must be an array with at least 3 elements,
values in the "names" array must be distinct (unique) strings, at least 3 characters long.
EDIT: Since Laravel 5.5 you can call validate() method directly on Request object like so:
$data = $request->validate([
"name" => "required|array|min:3",
"name.*" => "required|string|distinct|min:3",
]);
I have this array as my request data from a HTML+Vue.js data grid/table:
[0] => Array
(
[item_id] => 1
[item_no] => 3123
[size] => 3e
)
[1] => Array
(
[item_id] => 2
[item_no] => 7688
[size] => 5b
)
And use this to validate which works properly:
$this->validate($request, [
'*.item_id' => 'required|integer',
'*.item_no' => 'required|integer',
'*.size' => 'required|max:191',
]);
The recommended way to write validation and authorization logic is to put that logic in separate request classes. This way your controller code will remain clean.
You can create a request class by executing php artisan make:request SomeRequest.
In each request class's rules() method define your validation rules:
//SomeRequest.php
public function rules()
{
return [
"name" => [
'required',
'array', // input must be an array
'min:3' // there must be three members in the array
],
"name.*" => [
'required',
'string', // input must be of type string
'distinct', // members of the array must be unique
'min:3' // each string must have min 3 chars
]
];
}
In your controller write your route function like this:
// SomeController.php
public function store(SomeRequest $request)
{
// Request is already validated before reaching this point.
// Your controller logic goes here.
}
public function update(SomeRequest $request)
{
// It isn't uncommon for the same validation to be required
// in multiple places in the same controller. A request class
// can be beneficial in this way.
}
Each request class comes with pre- and post-validation hooks/methods which can be customized based on business logic and special cases in order to modify the normal behavior of request class.
You may create parent request classes for similar types of requests (e.g. web and api) requests and then encapsulate some common request logic in these parent classes.
Little bit more complex data, mix of #Laran's and #Nisal Gunawardana's answers
[
{
"foodItemsList":[
{
"id":7,
"price":240,
"quantity":1
},
{
"id":8,
"quantity":1
}],
"price":340,
"customer_id":1
},
{
"foodItemsList":[
{
"id":7,
"quantity":1
},
{
"id":8,
"quantity":1
}],
"customer_id":2
}
]
The validation rule will be
return [
'*.customer_id' => 'required|numeric|exists:customers,id',
'*.foodItemsList.*.id' => 'required|exists:food_items,id',
'*.foodItemsList.*.quantity' => 'required|numeric',
];
You have to loop over the input array and add rules for each input as described here: Loop Over Rules
Here is a some code for ya:
$input = Request::all();
$rules = [];
foreach($input['name'] as $key => $val)
{
$rules['name.'.$key] = 'required|distinct|min:3';
}
$rules['amount'] = 'required|integer|min:1';
$rules['description'] = 'required|string';
$validator = Validator::make($input, $rules);
//Now check validation:
if ($validator->fails())
{
/* do something */
}
The below code working for me on array coming from ajax call .
$form = $request->input('form');
$rules = array(
'facebook_account' => 'url',
'youtube_account' => 'url',
'twitter_account' => 'url',
'instagram_account' => 'url',
'snapchat_account' => 'url',
'website' => 'url',
);
$validation = Validator::make($form, $rules);
if ($validation->fails()) {
return Response::make(['error' => $validation->errors()], 400);
}
In my Case it works fine
$validator = Validator::make($request->all(), [
"names" => "required|array|min:3",
"*.names"=> "required|string|distinct|min:3",
]);

Request Validation with Laravel 5.3 for Multiple rows

My Request File rules are
public function rules()
{
return [
'mobile' => 'required',
'code' => 'required',
];
}
My input data can be a simple => for which the request validation is working fine.
{
"mobile":"81452569",
"code":"4858"
}
My input data can be a complex too => for which the request validation is not working fine.
[{
"mobile":"81452569",
"code":"4858"
},
{
"mobile":"81452570",
"code":"4858"
}]
How to validate for multiple rows with request.
I would sent it all in array to the request object like so:
"data" => [
[
"mobile" => "81452569",
"code" => "4858"
],
[
"mobile" =>"81452570",
"code" =>"4858"
]
];
Then in your validation rules do this:
public function rules()
{
return [
'data.*.mobile' => 'required',
'data.*.code' => 'required',
];
}

How to validate array input in laravel?

<input type="text" name="name[2]">
I tried validate like this, but didn't work correctly
$valid = Validator::make($request->all(), [
//'name.2' => 'required',
'name[2]' => 'required',
]);
-- Laravel Framework version 5.3.26
A nice way would be using Form Requests and creating dynamic rules for your arrays, like this
public function rules()
{
$rules = [
'name' => 'required|max:255',
];
foreach($this->request->get('items') as $key => $val)
{
$rules['items.'.$key] = 'required|max:10';
}
return $rules;
}
Here's a nice article talking about this: https://ericlbarnes.com/2015/04/04/laravel-array-validation/
You may also validate each element of an array. For example, to validate that each e-mail in a given array input field is unique, you may do the following:
$validator = Validator::make($request->all(), [
'person.*.email' => 'email|unique:users',
'person.*.first_name' => 'required_with:person.*.last_name',
]);

Can I appy same rule for group of fields in Laravel5 request validation?

I am using laravel request form validation and I want to apply same rule for more than one field.Is it possible for in any simple way? or need to write code for individually.
My validation rule given below.
protected $rules = [
'phone' => ['max:11'],
'work_phone' => ['max:11'],
'mobile' => ['max:11'],
];
Can I group these filed in to single rule?
You can do some things inside the rules() method:
public function rules(){
$phoneRules = ['max:11'];
return [
'phone' => $phoneRules,
'work_phone' => $phoneRules,
'mobile' => $phoneRules
]
}
Or:
public function rules(){
$fields = ['phone', 'work_phone', 'mobile'];
return array_fill_keys($fields, ['max:11']);
}
In case you have other attributes to validate with other rules you'd need something like this:
public function rules(){
$fields = ['phone', 'work_phone', 'mobile'];
$phoneRules = array_fill_keys($fields, ['max:11']);
$otherRules = [
'foo' => 'required',
'bar' => 'min:30'
]
return array_merge($phoneRules, $otherRules);
}
You should refer to the Custom Validation Rules section of the documentation, which precisely address this problem : http://laravel.com/docs/5.0/validation#custom-validation-rules

Laravel: Validation unique on update

I know this question has been asked many times before but no one explains how to get the id when you're validating in the model.
'email' => 'unique:users,email_address,10'
My validation rule is in the model so how do I pass the ID of the record to the validation rule.
Here is my models/User
protected $rules_update = [
'email_address' => 'required|email|unique:users,email_address,'.$id,
'first_name' => "required",
'last_name' => "required",
'password' => "required|min:6|same:password_confirm",
'password_confirm' => "required:min:6|same:password",
'password_current' => "required:min:6"
];
models/BaseModel
protected $rules = array();
public $errors;
/*
* #data: array, Data to be validated
* #rules: string, rule name in model
*/
public function validate($data, $rules = "rules") {
$validation = Validator::make($data, $this->$rules);
if($validation->passes()) {
return true;
}
$this->errors = $validation->messages();
return false;
}
Just a side note, most answers to this question talk about email_address while in Laravel's inbuilt auth system, the email field name is just email. Here is an example how you can validate a unique field, i.e. an email on the update:
In a Form Request, you do like this:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user->id,
];
}
Or if you are validating your data in a controller directly:
public function update(Request $request, User $user)
{
$request->validate([
'email' => 'required|email|unique:users,email,'.$user->id,
]);
}
Update:
If you are updating the signed in user and aren't injecting the User model into your route, you may encounter undefined property when accessing id on $this->user. In that case, use:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user()->id,
];
}
A more elegant way since Laravel 5.7 is:
public function rules()
{
return [
'email' => ['required', 'email', \Illuminate\Validation\Rule::unique('users')->ignore($this->user()->id)]
];
}
P.S: I have added some other rules, i.e. required and email, in order to make this example clear for newbies.
One simple solution.
In your Model
protected $rules = [
'email_address' => 'sometimes|required|email|unique:users',
..
];
In your Controller, action:update
...
$rules = User::$rules;
$rules['email_address'] = $rules['email_address'] . ',id,' . $id;
$validationCertificate = Validator::make($input, $rules);
There is an elegant way to do this. If you are using Resource Controllers, your link to edit your record will look like this:
/users/{user}/edit OR /users/1/edit
And in your UserRequest, the rule should be like this :
public function rules()
{
return [
'name' => [
'required',
'unique:users,name,' . $this->user
],
];
}
Or if your link to edit your record look like this:
/users/edit/1
You can try this also:
public function rules()
{
return [
'name' => [
'required',
'unique:users,name,' . $this->id
],
];
}
From Laravel 5.7, this works great
use Illuminate\Validation\Rule;
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore($user->id),
],
]);
Forcing A Unique Rule To Ignore A Given ID:
Test below code:
'email' => 'required|email|unique:users,email_address,'. $id .'ID'
Where ID is the primary id of the table
If i understand what you want:
'email' => 'required|email|unique:users,email_address,'. $id .''
In model update method, for exemple, should receive the $id with parameter.
Sorry my bad english.
Here is the solution:
For Update:
public function controllerName(Request $request, $id)
{
$this->validate($request, [
"form_field_name" => 'required|unique:db_table_name,db_table_column_name,'.$id
]);
// the rest code
}
That's it. Happy Coding :)
The Best Option is here try just once no need more code when unique validation on updating data
'email' => 'unique:users,email_address,' . $userId,
hereemailis field name and users is table name and email_address is table attribute name which you want unique and $userid is updating row id
public function rules()
{
switch($this->method())
{
case 'GET':
case 'DELETE':
{
return [];
}
case 'POST':
{
return [
'name' => 'required|unique:permissions|max:255',
'display_name' => 'required',
];
}
case 'PUT':
case 'PATCH':
{
return [
'name' => 'unique:permissions,name,'.$this->get('id').'|max:255',
'display_name' => 'required',
];
}
default:break;
}
}
an even simpler solution tested with version 5.2
in your model
// validator rules
public static $rules = array(
...
'email_address' => 'email|required|unique:users,id'
);
You can try this.
protected $rules_update = [
'email_address' => 'required|email|unique:users,email_address,'. $this->id,
'first_name' => "required",
'last_name' => "required",
'password' => "required|min:6|same:password_confirm",
'password_confirm' => "required:min:6|same:password",
'password_current' => "required:min:6"
];
In Laravel 8.x you can use Rule::unique method as well
Forcing A Unique Rule To Ignore A Given ID:
use Illuminate\Validation\Rule;
public function update(Request $request, Post $post)
{
$validatedData = $request->validate([
'name' => ['required', 'max:60', Rule::unique('posts')->ignore($post->id)],
]);
$post->update($validatedData);
return redirect(route('posts.index'))->with('status', 'post updated successfully');
}
Do One step in controller
Works Fine with Laravel 9
$request->validate([
'name'=>'required|unique:categories,name,'.$id,
]);
If you have a separate rules method. You can use easier the following syntax.
public function rules()
{
return [
'email' => "required|unique:users,email,{$this->id}"
];
}
$rules = [
"email" => "email|unique:users, email, '.$id.', user_id"
];
In Illuminate\Validation\Rules\Unique;
Unique validation will parse string validation to Rule object
Unique validation has pattern: unique:%s,%s,%s,%s,%s'
Corresponding with: table name, column, ignore, id column, format wheres
/**
* Convert the rule to a validation string.
*
* #return string
*/
public function __toString()
{
return rtrim(sprintf('unique:%s,%s,%s,%s,%s',
$this->table,
$this->column,
$this->ignore ?: 'NULL',
$this->idColumn,
$this->formatWheres()
), ',');
}
There is a simple and elegant way to do this. If you are passing the user_id in a body request or through a query parameter.
e.g
/update/profile?user_id=
Then in your request rules
public function rules(Request $request)
{
return [
'first_name' => 'required|string',
'last_name' => 'required|string',
'email' => ['required','email', 'string', Rule::unique('users')->ignore($request->user_id )],
'phone_number' => ['required', 'string', Rule::unique('users')->ignore($request->user_id )],
];
}
Better Still, you can pass in auth->id() in place of $request->user_id to get the login user id.
Found the easiest way, working fine while I am using Laravel 5.2
public function rules()
{
switch ($this->method()) {
case 'PUT':
$rules = [
'name' => 'required|min:3',
'gender' => 'required',
'email' => 'required|email|unique:users,id,:id',
'password' => 'required|min:5',
'password_confirmation' => 'required|min:5|same:password',
];
break;
default:
$rules = [
'name' => 'required|min:3',
'gender' => 'required',
'email' => 'required|email|unique:users',
'password' => 'required|min:5',
'password_confirmation' => 'required|min:5|same:password',
];
break;
}
return $rules;
}
i would solve that by doing something like this
public function rules()
{
return [
'name' =>
'required|min:2|max:255|unique:courses,name,'.\Request::get('id'),
];
}
Where you get the id from the request and pass it on the rule
You can also use model classpath, if you don't want to hard code the table name.
function rules(){
return [
'email' => ['required','string',
Rule::unique(User::class,'email')->ignore($this->id)]
];
}
Here $this->id is either 0 or the record Id to be updated.
Use for Laravel 6.0
use Illuminate\Validation\Rule;
public function update(Request $request, $id)
{
// Form validation
$request->validate([
'category_name' => [
'required',
'max:255',
Rule::unique('categories')->ignore($id),
]
]);
}
After researching a lot on this laravel validation topic including unique column, finally got the best approach. Please have a look
In your controller
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class UserController extends Controller
{
public function saveUser(Request $request){
$validator = Validator::make($request->all(),User::rules($request->get('id')),User::$messages);
if($validator->fails()){
return redirect()->back()->withErrors($validator)->withInput();
}
}
}
saveUser method can be called for add/update user record.
In you model
class User extends Model
{
public static function rules($id = null)
{
return [
'email_address' => 'required|email|unique:users,email_address,'.$id,
'first_name' => "required",
'last_name' => "required",
'password' => "required|min:6|same:password_confirm",
'password_confirm' => "required:min:6|same:password",
'password_current' => "required:min:6"
];
}
public static $messages = [
'email_address.required' => 'Please enter email!',
'email_address.email' => 'Invalid email!',
'email_address.unique' => 'Email already exist!',
...
];
}
This is what I ended up doing. I'm sure there is a more efficient way of doing this but this is what i came up with.
Model/User.php
protected $rules = [
'email_address' => 'sometimes|required|email|unique:users,email_address, {{$id}}',
];
Model/BaseModel.php
public function validate($data, $id = null) {
$rules = $this->$rules_string;
//let's loop through and explode the validation rules
foreach($rules as $keys => $value) {
$validations = explode('|', $value);
foreach($validations as $key=>$value) {
// Seearch for {{$id}} and replace it with $id
$validations[$key] = str_replace('{{$id}}', $id, $value);
}
//Let's create the pipe seperator
$implode = implode("|", $validations);
$rules[$keys] = $implode;
}
....
}
I pass the $user_id to the validation in the controller
Controller/UserController.php
public function update($id) {
.....
$user = User::find($user_id);
if($user->validate($formRequest, $user_id)) {
//validation succcess
}
....
}
While updating any Existing Data Write validator as following:
'email' => ['required','email', Rule::unique('users')->ignore($user->id)]
This will skip/ignore existing user's id's unique value matching for the specific column.
Test below code:
$validator = Validator::make(
array(
'E-mail'=>$request['email'],
),
array(
'E-mail' => 'required|email|unique:users,email,'.$request['id'],
));
Since you will want to ignore the record you are updating when performing an update, you will want to use ignore as mentioned by some others. But I prefer to receive an instance of the User rather then just an ID. This method will also allow you to do the same for other models
Controller
public function update(UserRequest $request, User $user)
{
$user->update($request->all());
return back();
}
UserRequest
public function rules()
{
return [
'email' => [
'required',
\Illuminate\Validation\Rule::unique('users')->ignoreModel($this->route('user')),
],
];
}
update: use ignoreModel in stead of ignore
Very easy to do it ,
Write it at your controller
$this->validate($request,[
'email'=>['required',Rule::unique('yourTableName')->ignore($request->id)]
]);
Note : Rule::unique('yourTableName')->ignore($idParameter) , here $idParameter you can receive from get url also you can get it from hidden field.
Most important is don't forget to import Rule at the top.
If a login user want to update the email then auth() helper function will give us the login user id auth()->user()->id
Laravel helpers#method-auth
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore(auth()->user()->id),
],
]);
if Admin want to change the specific user information from User list then validation will be like this :
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore($request->user),
],
Laravel validation#rule-unique
$request object contain the current route related model objects. Which gives the model.
Try dd($request)
Most answers to this question refer to email_address, but in Laravel's inbuilt authentication system, the email field name is just email. Here is an example of validating a unique field, i.e. an email on the update:
Form Requests look like this:
public function rules()
{
return [
'email' => [ 'required','email', Rule::unique('users')->ignore($this->id ?? 0)]];
}
?? 0 If you use this then if hare id does not exist this request will not give you an error
Save
Whenever you access the id property of $this->user, you may encounter an undefined property if you haven't injected the User model into your route. If that is the case, use:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user()->id ?? 0,
];
}
?? 0 If you use this then if hare id does not exist this request will not give you an error
My solution:
$rules = $user->isDirty('email') ? \User::$rules : array_except(\User::$rules, 'email');
Then in validation:
$validator = \Validator::make(\Input::all(), $rules, \User::$messages);
The logic is if the email address in the form is different, we need to validated it, if the email hasn't changed, we don't need to validate, so remove that rule from validation.
For unique rule in the controller - which obviously will be different for the store method and the update method, I usually make a function within the controller for rules which will return an array of rules.
protected function rules($request)
{
$commonRules = [
'first_name' => "required",
'last_name' => "required",
'password' => "required|min:6|same:password_confirm",
'password_confirm' => "required:min:6|same:password",
'password_current' => "required:min:6"
];
$uniqueRules = $request->id
//update
? ['email_address' => ['required', 'email', 'unique:users,email' . $request->get('id')]]
//store
: ['email_address' => ['required', 'email', 'unique:users,email']];
return array_merge($commonRules, $uinqueRules);
}
Then in the respective store and update methods
$validatedData = $request->validate($this->rules($request));
This saves from defining two different rule sets for store and update methods.
If you can afford to compromise a bit on readability, it can also be
protected function rules($request)
{
return [
'first_name' => "required",
'last_name' => "required",
'password' => "required|min:6|same:password_confirm",
'password_confirm' => "required:min:6|same:password",
'password_current' => "required:min:6",
'email_address' => ['required', 'email', 'unique:users,email' . $request->id ?: null]
];
}
