I know this question has been asked many times before but no one explains how to get the id when you're validating in the model.
'email' => 'unique:users,email_address,10'
My validation rule is in the model so how do I pass the ID of the record to the validation rule.
Here is my models/User
protected $rules_update = [
'email_address' => 'required|email|unique:users,email_address,'.$id,
'first_name' => "required",
'last_name' => "required",
'password' => "required|min:6|same:password_confirm",
'password_confirm' => "required:min:6|same:password",
'password_current' => "required:min:6"
];
models/BaseModel
protected $rules = array();
public $errors;
/*
* @data: array, Data to be validated
* @rules: string, rule name in model
*/
public function validate($data, $rules = "rules") {
$validation = Validator::make($data, $this->$rules);
if($validation->passes()) {
return true;
}
$this->errors = $validation->messages();
return false;
}
Just a side note, most answers to this question talk about email_address
while in Laravel's inbuilt auth system, the email field name is just email
. Here is an example how you can validate a unique field, i.e. an email on the update:
In a Form Request, you do like this:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user->id,
];
}
Or if you are validating your data in a controller directly:
public function update(Request $request, User $user)
{
$request->validate([
'email' => 'required|email|unique:users,email,'.$user->id,
]);
}
Update:
If you are updating the signed in user and aren't injecting the User
model into your route, you may encounter undefined property when accessing id
on $this->user
. In that case, use:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user()->id,
];
}
A more elegant way since Laravel 5.7 is:
public function rules()
{
return [
'email' => ['required', 'email', \Illuminate\Validation\Rule::unique('users')->ignore($this->user()->id)]
];
}
P.S: I have added some other rules, i.e. required and email, in order to make this example clear for newbies.
