I am doing validation this way.
$rules = [
'email'=> 'required|regex:/^.+#.+$/i|unique:tab_example,email,'.$this>get('example_id').',example_id'
];
return $rules;
However, I am not getting success.
The error informs that
the email already exists
What I want is that if the email already exists and is from the same user does not need to inform that the email already exists.
I do not know what the problem is in my code.
You can use
'email' => "required|email|unique:users,email,{$id},id",
The id should be replaced with the primary key column name of the table you use for the unique check. The {$id} should be defined before $rules array like:
$id = $request->route('user')
Sometimes, you may wish to ignore a given ID during the unique check.
For example, consider an "update profile" screen that includes the user name, e-mail address, and location. Of course, you will want to verify that the e-mail address is unique.
However, if the user only changes the name field and not the e-mail field, you do not want a validation error to be thrown because the user is already the owner of the e-mail address.
you can use like:
'email' => [
'required',
Rule::unique('users')->ignore($user->id),
],
Try this
'email' => Rule::unique('users')->ignore($user->id, 'user_id');
Read Under the Section Forcing A Unique Rule To ignore A given Field
Try This way
$rules = [
'email'=> ['required', 'email', \Illuminate\Validation\Rule::unique('tab_example', 'email')->whereNot('example_id',$this->get('example_id'))]
];
Just use
$this->route('example_id')
instead of
$this>get('example_id')
And if you use resource route then use $this->route('user').
$rules = [
'email'=> 'required|regex:/^.+#.+$/i|unique:tab_example,email,'.$this->route('example_id').',example_id'
];
return $rules;

I have contacts table with field email and alteranate_email. While adding new contact i want to check email address should not present in either email or alteranate_email. For Example, There is contact present with alteranate_email = 'abc#example.com'. When I tried to add new contact with email = 'abc#example.com', it allows me to add new contact.
I have tried below code but its not working.
$validator = Validator::make($request->all(), [
'email' => ['nullable', 'email',
Rule::unique('contacts')->where(function ($query) use ($request) {
return $query->where('email', $request->email)->orWhere('alteranate_email', $request->email);
}),
],
]);
You try to use two unique instead of making new rule. Try these one line solution below.
'email' => 'nullable|email|unique:contacts,email|unique:contacts,alternate_email'
I have a field "image", type is file and need only to validate if image is selected, means it can be also empty.
I tried it so: 'avatar' => 'mimes:jpeg,jpg,png,gif|max:100000', but so it is also required.
I tried still with parameters present and sometimes but the field is still required.
How can I validate it only if image is selected?
If the "avatar" field may not be present in the input array you want to use:
'avatar' => 'sometimes|mimes:jpeg,jpg,png,gif|max:100000'
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.
If the "avatar" field will absolutely be in the input array and it's value will be then null you want to use:
'avatar' => 'nullable|mimes:jpeg,jpg,png,gif|max:100000'
The field under validation may be null. This is particularly useful when validating primitive such as strings and integers that can contain null values. To quickly accomplish this, add the nullable rule.
In your case, You have to check only if it is present or not null - Validating When there is value. So use sometimes
"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"
$v = Validator::make($data, array(
'email' => 'sometimes|required|email',
));
In your case,
$v = Validator::make($data, array(
'avatar' => 'sometimes|mimes:jpeg,jpg,png,gif|max:100000',
));
Note:
The following code will do nothing because there are no rules to validate against, done because even if it's present in the POST array, you should specify rules. and the doesn't make any difference.
$v = Validator::make($data, array(
'avatar' => 'sometimes',
));
You could try 'nullable' in your rules.
https://laravel.com/docs/5.3/validation#rule-nullable
First check the $request object. Check avatar is available or not in your request. Then try this:
'avatar' => 'sometimes|image|mimes:jpeg,bmp,png,gif|max:2048'
the solution i found that works best is using Rule::requiredIf
'cover' => [
'image',
Rule::requiredIf(function () {
if (some_condition) {
return false;
}
return true;
})
]
Take a scenario,
There are 2 fields available in the form.
1) input type file for manual upload.
2) input type = text to enter youtube video url.
is it possible using laravel built-in validations so that validation will be fired if user has left both fields empty!
I have gone through https://laravel.com/docs/5.3/validation but could not find what I wanted.
In your controller, you could do something like this:
$validator = Validator::make($request->all(), [
'link_upload' => 'required|etc|...',
]);
$validator2 = Validator::make($request->all(), [
'file_upload' => 'required|etc|...',
]);
if ($validator->fails() && $validator2->fails()) {
// return with errors
}
Try required-without-all validation rule. As given in documentation:
The field under validation must be present only when the all of the other specified fields are not present.
Assuming your fields name are url and file, your rule would be like below:
$rules = [
'url' => 'required_without_all:file',
'file' => 'required_without_all:url'
];
required_without:foo,bar,...
The field under validation must be present and not empty only when any of the other specified fields are not present.
Try this,
In youre update method add this
$this->validate($request, [
'fileName'=>'required',
'urlName'=>'required'
]);
dont forget to set the fillable in your model
protected $fillable = ['fileName','urlName'];
Hope this helps
I have a user model that needs to have unique email addresses but I also want to allow them to be left blank in case the user has no email...I see in docs there is a way to make a rule for unique and an exception for an id...but I'm not sure how to make this allow null or blank but unique if it is not. Sorry seems like this is simple but I can't think of the answer.
public static $adminrules =
'email' => 'email|unique:users,email,null,id,email,NOT_EMPTY'
);
Edit It may be that using the rule without required is enough since a blank or null would pass validation in those cases. I might have a related bug that making it so I can't add more than 1 blank email, so I can't verify this.
public static $adminrules =
'email' => 'email|unique:users'
);
I tried this. Adding 'nullable' before 'sometimes'.
$validator = Validator::make($request->all(), [
'email' => 'nullable|sometimes|unique:users',
]);
You should try this:
$v->sometimes('email', 'email|unique:users,email', function($input)
{
return !empty($input->email);
});
$v is your validator object and you basically say that in case the email field is not empty it should also be unique (there shouldn't be a users table record with this value in email column).
In your Requests/UserRequest you'd have something like
public function rules()
{
return [
'email' => [
'nullable',Rule::unique((new User)->getTable())->ignore($this->route()->user->id ?? null)
]
];
}
The usage of nullable is what allows the field to be nullable. The other part is to check if the email is unique in the User model table.
If you wish to validate if the field is unique
between two fields please refer to this answer.
in another table, then add the following to your rules
'exists:'.(new ModelName)->getTable().',id'
You should try to change your structure of database to make the field email is nullable. And in the rules try this :
$this->validate($request,
[
'email' => 'email',
]
);
if(isset($request->address))
{
$this->validate($request,
[
'email' => 'email|unique:users'
]
);
}
This is my first time using Laravel 4. I am sending some input. There is an email in the input. I am trying to check whether that already exists or not. If it does than it should send some error. But it is saying there is no such column in my table.
Here is my code:
$rules = array(
'email' => array('required', 'email', 'unique:users, user_email'),
'password' => array('required', 'min:7', 'unique:users, user_password')
);
$validation = Validator::make(Input::all(), $rules);
if($validation->fails())
{
$messages = $validation->messages();
dd($messages);
}
My table name is users and column name is user_email and user_password. The name of the input field is email.
Reading through the documentation for validation rules, I do not see any spacing between column names, and the column info. It may be that spaces are not stripped from the data, and this would probably be the cause of your error. Remove the spacing issues, and it should work: unique:users,user_email,etc.
(Note, this is an expanded answer based off of my comment, which solved the user's problem).
