In Laravel validation Request, how to handle unique for different colums while update

Question

I had a Employee form for its validation while update I have created a validation request as EmployeeEdit and while updating employee form content in controller I am passing this validation request to validate data.

but the employee form has various fields, which I have to check for uniqueness with different tables. for example, employee form has a emp_id field which i have to check for uniqueness in users table, mobile number to check-in employees table.

How to check uniqueness except for current id.

my rules in EmployeeEdit Request

return [
         'emp_id' => 'nullable|max:255|unique:users,'.$this->get('emp_id'),
         'code' => 'nullable|unique:employees|max:255'.$this->get('code'),
         'mobile_number' => 'required|unique:employees|max:255,'.$this->get('mobile_number'),
 ];

My Controller:

public function doEdit(EmployeeEdit $request, $id)
    { 
        echo "Validation passed";
        exit;
    }

Problem: I don't know how to pass these fields like emp_id, mobile_number from the request so that they are ignored for the current request and should be checked for other data for uniqueness.

Answer 1

use Illuminate\Validation\Rule;

return [
         'emp_id' => [
                      'nullable',
                      'max:255',
                      Rule::unique('users', 'emp_id')->ignore(\Auth::user()->id),
         ],
 ];

Answer 2

Got the solution from @serhii comment

Now in EmployeeEdit Request , i have added (on top)

use Illuminate\Validation\Rule;

public function rules()
    {
        return [
                'emp_id' => ['nullable','max:255', Rule::unique('users', 'emp_id')->ignore($this->id)],
                'code' => ['nullable','max:255', Rule::unique('employees', 'code')->ignore($this->id,'user_id')],
                'mobile_number' => ['nullable','max:255', Rule::unique('employees', 'mobile_number')->ignore($this->id,'user_id')],

NOTE: Since the $this->id is id from the users table, in order to use it in employees table (which have user_id as a foreign key) I have to explicitly define a column in employees table rule.
