5 Ways To Simplify Laravel Form Building

Quick Links :

The art of form building in Laravel can be a daunting task, especially for those new to the framework. Forms are an essential part of any web application, allowing users to interact with your site and provide valuable data. However, building forms from scratch can be time-consuming and tedious. Fortunately, Laravel provides several tools and techniques to simplify the form-building process.

In this article, we'll explore five ways to simplify Laravel form building, making it easier to create robust, secure, and user-friendly forms.

1. Using Laravel's Built-in Form Helpers

Laravel provides a range of form helpers that can simplify the process of creating forms. These helpers can be used to generate HTML form elements, such as text inputs, checkboxes, and select boxes. By using these helpers, you can reduce the amount of code needed to create a form and make your code more readable.

For example, you can use the Form::text() helper to create a text input:

{{ Form::text('name', null, ['class' => 'form-control']) }}

This will generate the following HTML:

Creating a Form with Form Helpers

Here's an example of how you can use form helpers to create a simple form:

{{ Form::open(['route' => 'users.store', 'method' => 'post']) }}
  {{ Form::text('name', null, ['class' => 'form-control']) }}
  {{ Form::email('email', null, ['class' => 'form-control']) }}
  {{ Form::password('password', ['class' => 'form-control']) }}
  {{ Form::submit('Create User', ['class' => 'btn btn-primary']) }}
{{ Form::close() }}

This will generate a form with three input fields (name, email, and password) and a submit button.

2. Using a Package like Laravel Form Builder

While Laravel's built-in form helpers can simplify the form-building process, they can become cumbersome when dealing with complex forms. That's where packages like Laravel Form Builder come in. This package provides a simple and elegant way to build forms in Laravel.

With Laravel Form Builder, you can define your form fields in a separate file, making it easy to manage and maintain your forms. You can also use the package's built-in validation features to validate user input.

Defining a Form with Laravel Form Builder

Here's an example of how you can define a form with Laravel Form Builder:

// app/Forms/UserForm.php

namespace App\Forms;

use Kris\LaravelFormBuilder\Form;

class UserForm extends Form
{
    public function buildForm()
    {
        $this
            ->add('name', 'text')
            ->add('email', 'email')
            ->add('password', 'password');
    }
}

You can then use the form in your controller like this:

// app/Http/Controllers/UserController.php

namespace App\Http\Controllers;

use App\Forms\UserForm;

class UserController extends Controller
{
    public function create()
    {
        $form = new UserForm();
        return view('users.create', compact('form'));
    }
}

3. Using a Front-end Framework like Bootstrap or Tailwind CSS

While Laravel's form helpers and packages like Laravel Form Builder can simplify the form-building process, they don't necessarily make your forms look visually appealing. That's where front-end frameworks like Bootstrap or Tailwind CSS come in.

These frameworks provide pre-built CSS classes that you can use to style your forms and make them look more visually appealing. With Bootstrap, for example, you can use the form-control class to style your input fields and the btn btn-primary class to style your submit button.

Styling a Form with Bootstrap

Here's an example of how you can style a form with Bootstrap:

{{ Form::open(['route' => 'users.store', 'method' => 'post']) }}
  

    {{ Form::text('name', null, ['class' => 'form-control']) }}
  
  

    {{ Form::email('email', null, ['class' => 'form-control']) }}
  
  

    {{ Form::password('password', ['class' => 'form-control']) }}
  
  

    {{ Form::submit('Create User', ['class' => 'btn btn-primary']) }}
  
{{ Form::close() }}

This will generate a form with styled input fields and a submit button.

4. Using Laravel's Validation Features

Validation is an essential part of form building, as it helps ensure that user input is valid and secure. Laravel provides a robust validation system that you can use to validate user input.

With Laravel's validation features, you can define validation rules for each form field and validate user input against those rules. You can also use Laravel's built-in validation messages to display error messages to the user.

Defining Validation Rules with Laravel

Here's an example of how you can define validation rules with Laravel:

// app/Http/Controllers/UserController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'name' => 'required|string',
            'email' => 'required|email',
            'password' => 'required|string|min:8',
        ]);

        // Store the user in the database
    }
}

This will validate the user input against the defined rules and display error messages if the input is invalid.

5. Using a Third-party Package like Laravel Collective

Finally, you can use a third-party package like Laravel Collective to simplify the form-building process. Laravel Collective provides a range of tools and features that can help you build robust, secure, and user-friendly forms.

With Laravel Collective, you can define your form fields in a separate file and use the package's built-in validation features to validate user input. You can also use the package's built-in HTML helpers to generate HTML form elements.

Defining a Form with Laravel Collective

Here's an example of how you can define a form with Laravel Collective:

// app/Forms/UserForm.php

namespace App\Forms;

use Collective\Html\FormFacade;

class UserForm extends FormFacade
{
    public function buildForm()
    {
        $this
            ->add('name', 'text')
            ->add('email', 'email')
            ->add('password', 'password');
    }
}

You can then use the form in your controller like this:

// app/Http/Controllers/UserController.php

namespace App\Http\Controllers;

use App\Forms\UserForm;

class UserController extends Controller
{
    public function create()
    {
        $form = new UserForm();
        return view('users.create', compact('form'));
    }
}

By following these five ways to simplify Laravel form building, you can create robust, secure, and user-friendly forms that meet your application's needs.
