How To Create and Validate Form in Laravel?

Laravel provides various validation rules that can be used to validate user input in a CRUD application. Here is an example of how to perform validation in a Laravel CRUD application:

In the controller method that handles the create or update operation, you can use the validate method to perform the validation. For example:

public function store(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users,email',
        'password' => 'required|min:8',
    ]);

    // Create the record using the validated data
    // ...
}

In this example, we use the validate method to validate the name, email, and password fields of the request. If the validation fails, Laravel will automatically redirect the user back to the form with the validation errors.

You can also use the Validator facade to perform more complex validation or to customize the error messages. For example:

use Illuminate\Support\Facades\Validator;

public function update(Request $request, $id)
{
    $validator = Validator::make($request->all(), [
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users,email,'.$id,
        'password' => 'nullable|min:8',
    ], [
        'name.required' => 'The name field is required.',
        'email.unique' => 'The email address is already in use.',
        'password.min' => 'The password must be at least 8 characters long.',
    ]);

    if ($validator->fails()) {
        return redirect()->back()
            ->withErrors($validator)
            ->withInput();
    }

    // Update the record using the validated data
    // ...
}

In this example, we use the Validator::make method to create a validator instance and specify the validation rules and error messages. If the validation fails, we manually redirect the user back to the form with the validation errors.

To display the validation errors in the view, you can use the @error directive or the ->has() and ->first() methods. For example:

@error('name') {{ $message }} @enderror

In this example, we use the @error directive to display the validation error message for the name field.

These are some examples of how to perform validation in a Laravel CRUD application. By using the built-in validation rules and error messages, you can easily validate user input and display validation errors to the user.
