Multiple inputs in one validation rule - laravel

return [
'contract_code' => 'required',
'name' => 'required|string',
'abbreviation' => 'required|string',
'linecount_divisor' => 'required|integer'
];
// into input fields => 'required'
How to shorten the validation rule in multiple inputs?


if You have the same validation rule for multiple and you want to shorten your code just use form requests.
php artisan make:request RequestName
And then in the controller Functions use it
public function save(RequestName $requestName)
{
}
don't forget to use that request class.
use App\Http\Requests\RequestName;


Here is a solution assuming all input fields need to have a common rule like required.
$rules = array_map(function($curr) { return [$curr => 'required']; }, array_keys(request()->all()));


Try this one in Laravel
$validation=array();
$validation= [
'contract_code' => 'required',
'name' => 'required|string',
'abbreviation' => 'required|string',
'linecount_divisor' => 'required|integer'
];
$this->validate($request,$validation);

Laravel validating that key in array is in an array of given strings

I'm building an API that takes in an array of 'additional_data' but I want some control over the fields that can be passed in.
Take the following JSON:
{
"name": "Joe Bloggs",
"additional_data": {
"type": "example",
"other_type": "example"
}
}
My current validation attempt:
return [
'name' => ['required'],
'additional_data.*' => ['sometimes', Rule::in(['type'])]
];
This always fails validation, what I'm looking for is to validate the key of the array so I can make sure the keys passed in are part of a 'whitelist'.

What you do now is you try to validate content of additional_data.type and additional_data.other_type.
You can do this by adding a custom validator. For example
Validator::extend('check_additional_data_keys', function($attribute, $value, $parameters, $validator) {
return is_array($value) && array_diff(array_keys($value), ['type', 'other_type']) === 0);
});
and use it inside your current rules
return [
'name' => ['required'],
'additional_data' => ['check_additional_data_keys'],
'additional_data.*' => ['required', 'string'],
];

Just specify your whitelist keys using the array validation rule:
return [
'name' => 'required',
'additional_data' => [
'sometimes',
'array:type',
],
];

1- In case you want applay same validation on all arrays' keys you can use the following:
return [
'name' => 'required',
'additional_data' => ['array', Rule::in(['type'])]
];
2- In case each key in the array needs different validation use the following:
return [
'name' => 'required',
'additional_data' => 'array',
'additional_data.ky1' => ['your validation here'],
'additional_data.ky2' => ['your validation here'],
];

Laravel get array of values imploded from Form Request

I have the following rules in my From Request:
return [
'brand_id' => 'required|numeric',
'name' => 'required|string',
'wage_type_id' => 'required|numeric',
'work_days' => 'required|array',
'weekly_min' => 'required|numeric',
'weekly_max' => 'required|numeric',
'weekly_utmost' => 'required|numeric',
'daily_std' => 'required|numeric',
'daily_min' => 'required|numeric',
'daily_max' => 'required|numeric',
];
One of them, work_days is supposed to be sent as an array.
I could create the work type from validated form request like
WorkType::create($request->all());
BUT I cannot store an array in database for sure.
Is there a way to get work_days imploded so that I can use the one line above to create my record from the request directly?
Note: I want the array imploded, not json encoded, because I'm going to insert into a field type of SET.

You can actually modify the request params before creating the model in your controller.
$request->merge([
"work_days" => implode(", ", $request->work_days)
]);
WorkType::create($request->all());
If you want it to be in the FormRequest, override the passedValidation() method
class SampleFormRequest extends FormRequest
{
public function passedValidation()
{
$this->request->add([
"work_days" => implode(", ", $this->request->get("work_days"))
]);
}
}
But for me, I prefer writing all properties separately and not using the $request->all()

Validation : Laravel

In ContactsRequest.php
public function rules()
{
return [
'org_id' => 'required',
'name' => 'required',
'office' => 'required',
'mobile' => 'required_without:home',
'home' => 'required_without:mobile'
];
}
So basically what i want is , i have a form which will be taking the attributes specified in the code. But i want to modify code so that entering either one of 'home' or 'mobile' will allow me to create the new user.
What should be done.Any help would be appreciated

Laravel - Validate value against string

I am running some basic validation inside a Laravel 5.5 controller like this...
$this->validate($request, [
'name' => 'required|max:30',
'email' => 'required|unique:users|email',
'password' => 'required|max:20',
'mykey' => 'required',
]);
Is there a way to check if 'mykey' matches a php string I have saved? I know I can do an if statement and compare them but wondered if there was a way I could do this inside the validation itself?

You can use in rule, This works for n number of values
$request->validate([
'name' => 'required|max:30',
'email' => 'required|unique:users|email',
'password' => 'required|max:20',
'mykey' => [
Rule::in([env('MY_KEY'),config('app.another_key')]),
]
]);

Laravel provides a regex option for validation. Depending on the complexity of the string comparison it may be useful:
https://laravel.com/docs/5.5/validation#rule-regex

You can this rule:
$key = "my_saved_key"
$request->validate([
'name' => 'required|max:30',
'email' => 'required|unique:users|email',
'password' => 'required|max:20',
'mykey' => 'in:' . $key,
]
]);

Validate whether multiple fields are unique simultaneously in laravel 5

This my request class rules.
return [
'title' => 'required|unique:event_cals,title',
'eventDate' => 'required|date|after:yesterday',
'venue' => 'required',
'time' => 'required',
'type' => 'required',
'unique:event_cals,eventDate,NULL,id,venue,$request->venue,time,$request->time'
];
I want to validate a rule like below.
'eventDate' && 'venue' && 'time' => 'unique'
There I need to check if there any row without same eventDate, venue and time altogether. Anyone knows how to declare such a rule?
This is the snapshot of db table.

Here is the possible solution:
<?php
return [
'title' => 'required|unique:event_cals,title',
'eventDate' => 'required|date|after:yesterday',
'venue' => 'required',
'time' => 'required',
'type' => 'required',
'event_date' => "unique:event_cals,event_date,NULL,id,venue,{$request->venue},time,{$request->time}",
];
I again want to highlight that; if you want that validator to work, you should make sure that the event_date and time should be correctly formatted.
An example unique check with additional wheres from our running project's update requests:
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
$id = $this->route('money');
return $rules = [
'name' => "required|string|min:3|max:255|unique:moneys,name,{$id},id,deleted_at,NULL,access,public",
];
}
