When I use the Validation feature in Laravel, how can I add a pre-defined strings that are allowed in an Input?
For example, let's say I want the Input to contain only one of the following: foo,bar,baz, how can I do that?
$validator = Validator::make($credentials, [
'profile' => 'required|max:255', // Here I want Predefined allowed values for it
]);
Best to use the 'in' validation rule like this:
$validator = Validator::make($credentials, [
'profile' => ["required" , "max:255", "in:foo,bar,baz"]
]);
It is recommended in Laravel docs to put the validation rules in an array when they get bigger and I thought 3 rules were sufficient. I think it makes it for a more readable content but you do not have to. I added the regex portion below and I have it works. I am not that great with regexing stuff. Let me know.
$validator = Validator::make($credentials, [
'profile' => ["required" , "max:255", "regex:(foo|bar|baz)"]
]);
Works for me in Laravel 9:
use Illuminate\Validation\Rule;
Validator::make($data, [
'toppings' => [
'required',
Rule::notIn(['sprinkles', 'cherries']),
],
]);
Docs: https://laravel.com/docs/9.x/validation#rule-not-in
For the opposite you could use Rule::in(['foo', 'bar', 'baz'])

I am trying to check unique validation on three columns employee_id,designation_id,station_id but the data are coming as an array which is making my situation unique and different from other SO questions/answers. I already checked few question like below: checks unique validation on multiple columns
But in my case, I can't get the value as they are inside an array. I also tried to implement Custom Rule or Request but in vain. For all the attempts, I am failing to get the field value such as $request->employee_id as they are inside an array for my case. May be I'm not trying it right.
Controller Code:
$this->validate($request, [
'posting.*.employee_id' => 'required,unique: // what to do here ??',
'posting.*.designation_id' => 'required',
'posting.*.station_id' => 'required',
'posting.*.from_date' => 'required|date',
]);
I am trying to validate uniqueness for both create and update (along with ignore $this->id facility) but don't know how to implement it here for array. It would be no problem if there was no array. Any help/suggestion/guide is much appreciated. Thanks in advance.
You can do this by creating a rule i.e UniquePosting so your controller code would look like
$this->validate($request, [
'posting' => ['required'],
'posting.*' => ['required', new UniquePosting()],
'posting.*.employee_id' => 'required',
'posting.*.designation_id' => 'required',
'posting.*.station_id' => 'required',
'posting.*.from_date' => 'required|date',
]);
Now inside your UniquePosting rule passes function will look like
public function passes($attribute, $value) {
$exists = Posting::where(['employee_id' => $value['employee_id'], 'designation_id' => $value['designation_id'],'station_id' => $value['station_id')->exists();
return !$exists;
}
Add any change if needed, overall that's the concept for testing uniqueness of the whole array.
I use laravel 5.6 and I try to use validate to check my input.
But I have an issue with required_without.
I have 4 input : heure_bureau / heure_supp_bureau / heure_terrain / heure_supp_terrain
I must fill one input at least. So if I fill heure_bureau, the others aren't necessary.
So I use this code :
$validator = \Validator::make($request->all(), [
'heures_bureau' => 'nullable|date_format:"H\hi"|required_without:heures_supp_bureau,heures_terrain,heures_supp_terrain|before:07h45',
'heures_supp_bureau' => 'nullable|date_format:"H\hi"|required_without:heures_bureau,heures_terrain,heures_supp_terrain|before:13h15',
'heures_terrain' => 'nullable|date_format:"H\hi"|required_without:heures_bureau,heures_supp_bureau,heures_supp_terrain|before:07h45',
'heures_supp_terrain' => 'nullable|date_format:"H\hi"|required_without:heures_bureau,heures_supp_bureau,heures_terrain|before:13h15'
], $messages);
But it doesn't work. I have an error for each other input when I fill one.
If I use requried_without with only one input, it work well but not when I use it with multiple inputs.
Where am I wrong ?
Thank for your help !
try this:
$validator = \Validator::make($request->all(), [
'heures_bureau' => 'nullable|date_format:"H\hi"|required_without_all:heures_supp_bureau,heures_terrain,heures_supp_terrain|before:07h45',
'heures_supp_bureau' => 'nullable|date_format:"H\hi"|required_without_all:heures_bureau,heures_terrain,heures_supp_terrain|before:13h15',
'heures_terrain' => 'nullable|date_format:"H\hi"|required_without_all:heures_bureau,heures_supp_bureau,heures_supp_terrain|before:07h45',
'heures_supp_terrain' => 'nullable|date_format:"H\hi"|required_without_all:heures_bureau,heures_supp_bureau,heures_terrain|before:13h15'
], $messages);
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',
]);
I have a form with three fields: title, body and photo[]. I'm trying to validate it so that at least one item is filled in, but I can't seem to get it to work. If I upload a file I still receive an error for title and body.
public function rules()
{
return [
'title' => 'required_without_all:body,photo.*',
'body' => 'required_without_all:title,photo.*',
'photo.*' => 'required_without_all:title,body',
'photo.*' => 'mimes:jpeg,gif,png',
];
}
Update: Jonathan pointed out that I had my rules wrong. I've fixed them and am now using this. It's still not working; when I try to upload a photo I get the error message that the other fields are required.
public function rules()
{
return [
'title' => 'required_without:body,photo.*',
'body' => 'required_without:title,photo.*',
'photo.*' => 'required_without:title,body|mimes:jpeg,gif,png',
];
}
If you're looking to ensure the photo field is an array then you need 'photo' => 'array' and then you can use 'photo.*' => '' for the other validations of the array's children.
The rules are separated by a pipe character | so if you were going to combine the two in your example it would be 'photo.*' => 'required_without_all:title,body|mimes:jpeg,gif,png',. I don't see you using the pipe to separate rules so I can't be sure you are aware of it.
This may have been where you were going wrong in the first place (two keys in the associative array that are identical) and some kind of precedence taking affect negating one of the rules.
You could try something like this (for the record I think you were on the right track to begin with using required_without_all as this stipulates the need to be required if all of the given fields are missing):
public function rules()
{
return [
'title' => 'required_without_all:body,photo',
'body' => 'required_without_all:title,photo',
'photo' => 'array',
'photo.*' => 'required_without_all:title,body|mimes:jpeg,gif,png',
];
}
Reference
previously I have used validation within a Request class e.g.
public function rules()
{
return [
'userName' => 'required', 'min:3',
'userEmail' => 'required|email',
'departmentId' => 'required',
'slug' => 'required',
];
}
But I now have another form but I can't see any options within the documentation that might help me.
Basically, lets say I have a form with the same fields as the validation above. The only time validation should fail is if ALL fields contain absolutely no data. So if I put something like "hi" within the slug input and submit, it should pass the validation.
Would something like this be possible?
Thanks
You can probably use the required_without_all validation rule.
http://laravel.com/docs/5.1/validation#rule-required-without-all
The field under validation must be present only when all of the other
specified fields are not present.
It would give you something like
public function rules()
{
return [
'userName' => 'required_without_all:userEmal,departmentId,slug','min:3',
'userEmail' => 'required_without_all:userName,departmentId,slug|email'
...
];
}
But it's not very handy if you have a lot of fields.
If you have to deal with many fields, creating a custom validator might be a better solution.
