I have two datepicker input fields: from and to. To ensure that field value to is greater than field value from, I use the after validation rule. Everything is fine up until I leave the from input value null. Because I am applying the validation rule using the input value from.
How can I combine the required and after validation rules without running into this problem?
$from = $request->input('from');
$from = Carbon::createFromFormat('Y-m-d\TH:i', $from)->format('Y-m-d H:i A');
$attributes= request()->validate([
'from' => 'required|date',
'to'=> 'nullable|date|after:'.$from,
]);
Data missing error while from input value is empty.
The laravel validation rule allows you to compare a field against another field. So you can simply add: after:from
See the documentation here.
$attributes = request()->validate([
'from' => 'required|date',
'to'=> 'nullable|date|after:from',
]);

So I have a Laravel form where I'm collecting data, I use same form for creating and updating the table. Problem is that I only want the input fields to be validated when they contain data, this is my validation logic.
$validated = $request->validate([
'site_name' => 'sometimes|string',
'site_email' => 'sometimes|email',
'site_keywords' => 'sometimes|string',
'site_description' => 'sometimes|string',
'site_acronym' => 'sometimes|string|max:7',
'site_favicon' => 'sometimes|mimes:jpg,png,jpeg,svg',
'site_logo' => 'sometimes||mimes:jpg,png,jpeg,svg',
'site_currency' => 'sometimes|string',
'site_currency_symbol' => 'sometimes|string',
]);
But when the form is submitted, laravel returns an error for empty input fields, e.g it returns an error like so "The site name must be a string." for the first validation rule.
What am I doing wrong please?
EDIT
So I took the advice from #roj-vroemen and modified my code by using the nullable validation rule and it works just fine now.
Here's the new code block
$validated = $request->validate([
'site_name' => 'string|nullable|sometimes',
'site_email' => 'email|nullable|sometimes',
'site_keywords' => 'string|nullable|sometimes',
'site_description' => 'string|nullable|sometimes',
'site_acronym' => 'string|nullable|sometimes|max:7',
'site_favicon' => 'mimes:jpg,png,jpeg,svg|nullable|sometimes',
'site_logo' => 'mimes:jpg,png,jpeg,svg|nullable|sometimes',
'site_currency' => 'string|nullable|sometimes',
'site_currency_symbol' => 'string|nullable|sometimes',
]);
You'll want to use nullable in this case. sometimes basically means it only runs the validation for that field when it's present in the data.
In short:
Use nullable when you want to allow null values.
https://laravel.com/docs/8.x/validation#rule-nullable
Use sometimes if your only want to validate the field when it's present in the given input array.
https://laravel.com/docs/8.x/validation#validating-when-present
Note: you might want to make sure to filter out the empty values as the fields containing null will still be there:
$validated = array_filter($validated);

$request->validate([

'surname' => 'required_with:name'
]);
$request->validate([

I am trying to validate the 'uuid' field so that it is mandatory if the 'typeUUID' field is marked 'type1'.
$validator = Validator::make($request->all(), [
'uuid' => 'required_if:typeUUID,==,type1|alpha_dash|size:36',
]);
If I select the value 'type1' it indicates that the field is mandatory, and when I set another value that is not mandatory, it validates' alpha_dash 'and' size: 36 and does not accept the field since it is sent empty.
What is the right way?
I know I could do it with a condition by checking the type at the beginning and then applying one or more rules. But I would like to know the correct way to do it.
I found the solution, is to add the rule 'nullable' after the rule 'required_if'.
$validator = Validator::make($request->all(), [
'uuid' => 'required_if:typeUUID,==,type1|nullable|alpha_dash|size:36',
]);
Using Laravel 5.4, my users have an auto-complete helper to put values into an input. I want to validate that each of the values exists in the database when inserting.
Inputted value for "unit" : "12,13,14"
How do I check that, unit "12" and unit "13" and unit "14" exist in the database before doing the insert?
$units = array_filter(array_unique(explode(",", $request->unit)));
// input "12,13,14" becomes [12,13,14]
$this->validate($request,[
'unit' => 'required|exists:units.id,'.$units,
]);
Do I have to use a custom validation rule, or does laravel have something handy like 'required|existsAllValuesInThisArray' sorta thing? Haven't found anything in documentation about it.
I also found this, but it's for like multiple select fields or checkboxes sorta thing from the looks of it.
$validator = Validator::make($request->all(), [
'person.*.email' => 'email|unique:users',
'person.*.first_name' => 'required_with:person.*.last_name',
]);
Update : I ended up using javascript to split the input into an array before sending it off for processing. So my input name became "units[]" instead of "units"
Try the following:
$this->validate($request,[ 'unit.*' => 'required|exists:units.id,'.$units, ]);
Since $units is an array, the rule unit.* should check for each element of the array.
How to set not require numeric validation for Laravel5.2? I just used this Code but when i don't send value or select box haven't selected item I have error the val field most be numeric... I need if request hasn't bed input leave bed alone. leave bed validate ...
$this->validate($request, [
'provinces_id' => 'required|numeric',
'type' => 'required',
'bed' => 'numeric',
]);
If I understood you correctly, you're looking for sometimes rule:
'bed' => 'sometimes|numeric',
In some situations, you may wish to run validation checks against a field only if that field is present in the input array. To quickly accomplish this, add the sometimes rule to your rule list
In Laravel 6 or 5.8, you should use nullable. But sometimes keyword doesn't work on that versions.
Use sometimes instead of required in validation rules. It checks if only there is a value. Otherwise it treats parameter as optional.
You may need nullable – sometimes and
present didn't work for me when combined with integer|min:0 on a standard text input type - the integer error was always triggered.
A Note on Optional Fields
By default, Laravel includes the TrimStrings and ConvertEmptyStringsToNull middleware in your application's global middleware stack. These middleware are listed in the stack by the App\Http\Kernel class. Because of this, you will often need to mark your "optional" request fields as nullable if you do not want the validator to consider null values as invalid.
Tested with Laravel 6.0-dev
Full list of available rules
In laravel 5.5 or versions after it, we begin to use nullable instead of sometimes.
according to laravel documentation 8 you must to set nullable rule
for example:
$validated = $request->validate([
'firstName' => ['required','max:255'],
'lastName' => ['required','max:255'],
'branches' => ['required'],
'services' => ['required' , 'json'],
'contract' => ['required' , 'max:255'],
'FixSalary' => ['nullable','numeric' , 'max:90000000'],
'Percent' => ['nullable','numeric' , 'max:100'],
]);
in your case :
$this->validate($request, [
'provinces_id' => 'required|numeric',
'type' => 'required',
'bed' => 'nullable|numeric',
]);
