To create custom validation in bagisto :-

Step 1: Inside the package where you need to create validation for go in Modal say User model. Create a custom validation rule class:

use Illuminate\Contracts\Validation\Rule;
use App\Models\User;

class UniqueUserDataRule implements Rule
{
    public function passes($attribute, $value)
    {
        // Check if the value is not empty
        if (empty($value)) {
            return false;
        }

        // Check if the value is unique in the corresponding table
        return !User::where($attribute, $value)->exists();
    }

    public function message()
    {
        // Define your custom validation error message here
        return 'The :attribute is already taken.';
    }
}

use Illuminate\Contracts\Validation\Rule;

use App\Models\User;

class UniqueUserDataRule implements Rule

{

public function passes($attribute, $value)

{

// Check if the value is not empty

if (empty($value)) {

return false;

}

// Check if the value is unique in the corresponding table

return !User::where($attribute, $value)->exists();

}

public function message()

{

// Define your custom validation error message here

return 'The :attribute is already taken.';

}

In this example, we assume that the user data is stored in a users table, and you’re using the User model.

Step 2 : Use the custom validation rule in your controller or form request:

use App\Rules\UniqueUserDataRule;

public function store(Request $request)
{
     $request->validate([
        'name' => ['required', new UniqueUserDataRule],
        'email' => ['required', 'email', new UniqueUserDataRule],
        'phone' => ['required', new UniqueUserDataRule],
    ]);

    // The validation has passed, continue with your logic
}

use App\Rules\UniqueUserDataRule;

public function store(Request $request)

{

$request->validate([

'name' => ['required', new UniqueUserDataRule],

'email' => ['required', 'email', new UniqueUserDataRule],

'phone' => ['required', new UniqueUserDataRule],

]);

// The validation has passed, continue with your logic

}

In the example above, name, email, and phone are the fields you want to validate. The UniqueUserDataRule is used for each field, ensuring that the values are required and unique. The required and email rules are added to the email field to enforce required and valid email input.

Make sure to include the namespace of the custom validation rule class at the top of your controller or form request file, like use App\Rules\UniqueUserDataRule;, depending on the location of your custom validation rule file.

By using this custom validation rule, you can ensure that the user name, email, and phone number fields are both required and unique, displaying the defined error message when the validation fails.
