How to Insert Form Array Values Into the Database in Laravel

In Laravel, handling form submissions and inserting array values into the database is a common task, especially when dealing with dynamic or repeated input fields.

In this tutorial, we’ll explore how to insert form array values into the database effectively using Laravel. We’ll cover creating migrations, models, controllers, and views to achieve this goal.

Let’s get started!

Step 1: Create a Laravel Project

Begin by creating a new Laravel project using the following commands in your terminal:

composer create-project laravel/laravel switch-example
cd switch-example

Step 2: Create Model and Migration

Now lets generate the migration and model files we’ll use to store an array of answers. To do this, open your terminal and run the following commands:

php artisan make:model Answer
php artisan make:migration create_answers_table --create=answers

Step 3: Add Migration Code

Now lets open the generated migration file and in the up() method define the columns needed for the answers table:


use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
     * Run the migrations.
    public function up(): void
        Schema::create('answers', function (Blueprint $table) {

     * Reverse the migrations.
    public function down(): void

Step 4: Run the Migrations

Create the table in the database by running the following artisan command:

php artisan migrate

Step 5: Add Model Code

Now, go to app/Models and open Answer.php and add the code below. This will make the properties question_id and answer mass assignable:


namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Answer extends Model
    protected $fillable = [

Step 6: Create a Controller

Now, let’s create a controller to handle the questionnaire form by running the following artisan command:

php artisan make:controller QuestionnaireController

Step 7: Add Controller Code

As an example, we’ll create questions related to customer satisfaction during a hotel stay. We will use a controller to present the form, validate and store it and show a thank you message.

In the index() method, we’ll define a hardcoded array $questions containing the question IDs and their corresponding content.

The store() method will handle the form submission, perform basic validation, and insert the answers into the database. Normally this would validate that the question_id is known in a questions table but for simplicity’s sake we’ll allow any positive integer.

Finally, the thankYou() method will render a view with a thank you message for the user.

To implement these open the generated Controller at app/Http/Controllers/QuestionnaireController.php and add the following code:


namespace App\Http\Controllers;

use App\Models\Answer;
use Illuminate\Http\Request;

class QuestionnaireController extends Controller
    public function index()
        // For simplicity we define a harcoded array with questions here.
        // A real-world app would typically read these from a table instead
        $questions = [
            1 => 'Describe your overall experience during your stay:',
            2 => 'Please provide feedback on the cleanliness of the room:',
            3 => 'Share your thoughts on the helpfulness and courtesy of the staff:',
            // Add more questions as needed
        return view('questionnaire', compact('questions'));

    public function store(Request $request)
        // Validate the form
        $validatedData = $request->validate([
            // question_id must be an integer greater than 0
            'answers.*.question_id' => 'required|integer|gt:0',
            // answer can contain any string up to 255 characters
            'answers.*.answer' => 'required|string|max:255',
        // Loop through submitted answers and store each into the database
        foreach ($validatedData['answers'] as $answerData) {
            // Use Eloquent Model `Answer` to store each answer
                'question_id' => $answerData['question_id'],
                'answer' => $answerData['answer']

        return redirect()->route('questionnaire.thankYou');

    public function thankYou()
        return view('thankYou');

Step 8: Create a View

Now, we’ll create two views: one to display the questionnaire with our questions, and another for the thank you page.

  1. First create a new file at resources/views/questionnaire.blade.php for our questionnaire form and add the following code:
<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="" rel="stylesheet">
<div class="container mt-5">
    <h1>Hotel Stay Questionnaire</h1>
    <form action="{{ route('') }}" method="POST">
        @foreach($questions as $id => $question)
            <div class="mb-3">
                <label for="question{{ $id }}" class="form-label">{{ $question }}</label>
                <input type="text" class="form-control" id="question{{ $id }}" name="answers[{{ $id }}][answer]">
                <input type="hidden" name="answers[{{ $id }}][question_id]" value="{{ $id }}">
                @error('answers.' . $id . '.answer')
                <div class="alert alert-danger">{{ $message }}</div>
        <button type="submit" class="btn btn-primary">Submit</button>

The code above loops through the array of questions, displaying each question with an input field for the user’s answer. It also adds code to show validation errors of each field, should they occur.

  1. Then create a new file at resources/views/thankyou.blade.php and add:
<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Thank You!</title>
    <link href="" rel="stylesheet">
    <div class="container mt-5">
        <h1>Thank You for Your Feedback!</h1>
        <p>We appreciate you taking the time to complete the questionnaire.</p>

Step 9: Add Routes

Open the file at routes/web.php in your Laravel project. Add the code below to add routes for displaying the questionnaire form and for showing the trankyou page.


use Illuminate\Support\Facades\Route;
use App\Http\Controllers\QuestionnaireController;

Route::get('/questionnaire', [QuestionnaireController::class, 'index'])->name('questionnaire.index');
Route::post('/submit', [QuestionnaireController::class, 'store'])->name('');

Step 10: Start the Application

To run the application, use the following Artisan command:

php artisan serve

Visit in your browser to access the questionnaire form, fill in some answers and submit:

Our Questionnaire Form Showing the Array of Inputs Where the Answers can be Filled in

When we’ve filled in the form it will either show validation error or redirect to the thank you page. It should look like this:

The Thank You Page After the Array was Stored Successfully

Afterwards our database contains all the answers given by the user. It should look like the following:

The Contents of Our answers Table After Inserting the Sample Data


And there you have it! We’ve successfully set up a Laravel project complete with migrations, models, controllers, and views, allowing us to effortlessly capture form array values and store them in the database

Feel free to customize the form further by adding a questions table to replace the hardcoded array. Also it would be interesting to add support for different input types like checkboxes or radio buttons.

So, go ahead, dive into your project, customize the features to your liking and start gathering valuable insights from your users. Happy coding!
