I created a form with the following fields:
Name
Email
Country
City
Address
If the user selects a country that has states (ex. United States) then the form transforms to:
Name
Email
Country
State
City
Address
To validate this I created a separate form request like so:
public function rules()
{
return [
'name' => 'required|max:255',
'email' => 'required|email,
'country_id' => 'required|integer',
'state_id' => 'nullable|integer',
'city_id' => 'required|integer',
'address' => 'required',
];
}
The problem is that if I leave it like that, then if I don't select a state it will pass validation.
If i make it:
'state_id' => 'sometimes|nullable|integer',
Then again it passes validation.
If I make it:
'state_id' => 'required|nullable|integer',
It will not pass validation, but then again it will throw a validation error if there is no state field in the form.
I read a lot of articles about this but nothing seems to solve it for me.
PS1: I want to solve this in the form request, not in the controller. I assume that an
if($request->has('states')){...}
can help, but then again, i would like to keep everything tidy in the form request.
PS2: I am using VueJS and Axios to add/remove states from the form. The whole form is actually a Vue component.
Any clues?
Thank you in advance!
You can conditionally add rules via the sometimes method on Validator.
$v->sometimes('state_id', 'required|integer', function ($input) {
return in_array($input->countries, [1,2,3,4...]
});
You could use the required_with line of parameters, but because the validation is based on the value of the input instead of just the presence, the custom validation rule is probably your best bet.
Per https://laravel.com/docs/5.7/validation#conditionally-adding-rules

I have a dynamic phone number validation rule, and I need 2 values for it: number and country.
The library I'm using to validate the phone number is brick/phonenumber which can include the country code to parse it accurately.
So, my current working approach looks like this:
$request->validate([
'country' => ['required', 'max:2'],
]);
$request->validate([
'number' => ['required', new PhoneNumberValidator($request->input('country')],
]);
Because when I put it like this:
$request->validate([
'country' => ['required', 'max:2'],
'number' => ['required', new PhoneNumberValidator($request->input('country'))],
]);
The number validation runs even if the country is not valid. So I'd like to know if there's a way to have all the validations in one validate() call, so, having the country value validated before calling the number rule (I tried with bail but that stops the validations for 1 attribute, not the rest of attributes in the queue).
You can create a custom rule and validate both inputs at the same time.
You may also want to look at the various validation rules. You might find something helpful.
How can I validate my inputs from a GET method?
Example URL: localhost:8000?salary=2000&name=sample&description=vowewljfodigjfdglfd
In the URL I have 3 inputs and I want to validate:
Salary - should accept only numeric
Name - should accept only alphabetic
Description - should accept with max:1000
Somebody knows how to do this?
The Laravel validator doesn't care where the data came from. You can manually create a validator and pass it the query string data.
$validator = Validator::make($request->query(), [
'salary' => 'numeric',
'name' => 'alpha_num',
'description' => 'max:1000',
]);
if ($validator->fails()) {
// show an error
}

Is there any way to get original data in request?
I mean, in my case I want to validate updating user's in the form. I want the email to be unique on emails in database except on the email that user wrote to the form.
Laravel already has a validation rule for this, you can add an id of the user to ignore to your unique validator.
'email' => [
'required',
Rule::unique('users')->ignore($currentUser->id),
]
I used something like this:
'email' => ['sometimes', 'email', 'unique:users,email,'.$user->getKey().','.$user->getKeyName().',deleted_at,NULL', 'string'],
Not sure if it is the best solution but works. I kind of do not like it because the $user is based on hidden input from the request.
You can do it liks this:
'email' => 'unique:users,email,'.$user->id
The user id will allow you to keep updating the record but maintain the unique constraint on email. You don't need a hidden input field for $user->id btw.
I want to use email validation in admin form of my custom module. I've seen core module but couldn't get exact idea.
You can also validate the 'email' text field by adding a class ['validate-email'] in your form
$fieldset->addField(
'email',
'text',
[
'name' => 'email',
'label' => __('Email'),
'title' => __('Email'),
'required' => true,
'class' => 'validate-email'
]
);
Validation is Model's issue. Only model knows how your data should look like. You describe your data fields in model, so you should describe validation rules for this fields in the same place.
It seems to be obvious for me, but I'd gladly listen to opponents.
put database validation in the Model (assuming it's a db model) and http data validation in the controller. Xss filtering, for example, does not pertain to the Model. it pertains to the Controller in input and to the View in output
I found an answer by myself, I used PHP email validation in the save controller.
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.
