I am using laravel 9.
And I have this very simple validation rule (form request validation):
public function rules()
{
return [
'first_name' => 'required|max:50',
'last_name' => 'required|max:50',
'email' => [
'email',
Rule::unique('unknown_table')->where(function ($query) {
return $query->where('library_id', $this->library->id);
})
],
.......
What I do not understand is why my post is working with this table name "unknown_table", because this table really does not exist. I expected an exception but nothing happens !
Is this rule correctly written ?
I have understood my error. The "email" validation was twice in the rule array ! And it was the last one which was used of course.

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 am new in Laravel and I would like to have some directive on how to handle this situation.
I have two entities: Ad and Nomination. Ad can have many Nominations.
In a controller i receive two external inputs: [ad_id] and [nomination_id] both required.
What i have to do with these two inputs is:
Check if [ad_id] is an existing Ad entity and his attribute "active" is true.
Check [nomination_id] is an existing Nomination entity.
Only if [ad_id] was an existing Ad and [nomination_id] was an existing Nomination check if this Nomination belongs to this Ad.
Can you show me an example about how to manage this using only validation class?
You can write your validation rules like this
public function rules()
{
return [
'ad_id' => [
'bail',
'required',
Rule::exists('ads')->where(function ($query) use ($request) {
$query->where([
['active' => 1],
['id' => $request->ad_id]
]);
}),
],
'nomination_id' => [
'bail',
'required',
Rule::exists('nominations')->where(function ($query) use ($request) {
$query->where([
['ad_id' => $request->ad_id],
['id' => $request->nomination_id]
]);
}),
],
];
}
Assuming you have ads and nominations are tables name and primary key field is id and ad_id as foreign key in nominations table.
It's pretty straightforward - you can write validation rules just as you listed them in your question:
$validator = Validator::make($request->only('ad_id', 'nomination_id'), [
'ad_id' => 'required|exists:ads,id,active,1',
'nomination_id' => 'required|exists:nominations,id,ad_id,' . $request->ad_id,
]);
if ($validator->fails()) {
...
}
$inputAd = <some_value>;
$inputNomination = <some_value>;
$nomination = Nomination::where(['id' => $inputNomination])->with(['ads'])->first();
if(!$nomination || !($nomination->ad_id == $inputAd)) {
// not the same
}
// same
To validate the ad_id and nomination_id, you can use laravel in rule.
FormRequest Class
public function rules()
{
return [
'ad_id' => [
'required',
Rule::in(Ad::where('active', true)->pluck('id')->toArray()),
],
'nomination_id' => [
'required',
Rule::in(Nomination::where('id', $this->nomination_id)->where('ad_id', $this->ad_id)->pluck('id')->toArray()),
],
];
}
The Rule::in(Ad::where('active', true)->pluck('id')->toArray()), rule will check if the ad_id is present in the array of ids of Ad which have active field is true.
The Rule::in(Nomination::where('id', $this->nomination_id)->where('ad_id', $this->ad_id)->pluck('id')->toArray()), rule will check if the nomination_id is present in the array of ids of Nomination which is related to Ad.
I am trying to use unique on an email address in Laravel 5.5 validation like this..
$rules = [
'email' => 'email|unique:users,email,
];
This is working and is checking the 'users' table in the 'email' column
But if the email address is the same as the currently saved one then this also fails validation.
Is there a way I can add an exception rule to the validation to ignore $user-email?
The unique rule takes a third parameter: a record to ignore, see "Forcing A Unique Rule To Ignore A Given ID".
Pass in the ID of the record you do not wish to be included in the unique test, e.g:
$rules = [
'email' => 'email|unique:users,email,' . $user->id
];
THIS IS AN EASY SOLUTION
Just add $this->route('id') as the third parameter
if your route was defined like this:
Route::put('{company}', 'CompanyController#update')
->name('update');
then your parameter name is "company"
So in your FormRequest:
public function rules()
{
$rules = [
'url' => [
'required',
'url',
'unique:companies,url,'.$this->route('company') ?? 0
],
];
// dd($rules); << check yourself
return $rules;
}
This FormRequest works the same for insert or update.
this line will instruct to ignore "0" in case of insert
$this->route('company') ?? 0
I'm having an issue with required_without_all. I have three elements, and at least one should be filled. My file input's name is image[]. Adding an image but leaving title and body empty still results in a validation error, even though it shouldn't.
Any thoughts on what I'm doing wrong?
public function rules()
{
return [
'title' => 'required_without_all:body,image.*',
'body' => 'required_without_all:title,image.*',
'image.*' => 'required_without_all:body,title',
];
}
public function messages()
{
return [
'title.required_without_all' => 'At least one field is required',
'body.required_without_all' => 'At least one field is required',
'image.*.required_without_all' => 'At least one field is required',
];
}
Answered here: https://stackoverflow.com/a/39089295/2101328
Basically, add image as an array and remove the * from the rules.
There was also a bug in Laravel 5.3 that prevented similar from working; see this thread: https://github.com/laravel/framework/issues/15044#issuecomment-244364706
public function rules()
{
return [
'title' => 'required_without_all:body,image',
'body' => 'required_without_all:title,image',
'image' => 'array',
'image.*' => 'required_without_all:body,title',
];
}
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.
