Form builder for Laravel 5 inspired by Symfony's form builder. With help of Laravels FormBuilder class creates forms that can be easy modified and reused. By default it supports Bootstrap 3.

Laravel 4

For Laravel 4 version check laravel4-form-builder.

Bootstrap 4 support

To use bootstrap 4 instead of bootstrap 3, install laravel-form-builder-bs4.

Upgrade to 1.6

If you upgraded to >1.6.* from 1.5.* or earlier, and having problems with form value binding, rename default_value to value.

Installation

Using Composer

composer require kris/laravel-form-builder

Or manually by modifying composer.json file:

{
    "require": {
        "kris/laravel-form-builder": "1.*"
    }
}

And run composer install

Then add Service provider to config/app.php

    'providers' => [
        // ...
        Kris\LaravelFormBuilder\FormBuilderServiceProvider::class
    ]

And Facade (also in config/app.php)

    'aliases' => [
        // ...
        'FormBuilder' => Kris\LaravelFormBuilder\Facades\FormBuilder::class
    ]

Notice: This package will add laravelcollective/html package and load aliases (Form, Html) if they do not exist in the IoC container.

Quick start

Creating form classes is easy. With a simple artisan command:

php artisan make:form Forms/SongForm --fields="name:text, lyrics:textarea, publish:checkbox"

Form is created in path app/Forms/SongForm.php with content:

<?php

namespace App\Forms;

use Kris\LaravelFormBuilder\Form;
use Kris\LaravelFormBuilder\Field;

class SongForm extends Form
{
    public function buildForm()
    {
        $this
            ->add('name', Field::TEXT, [
                'rules' => 'required|min:5'
            ])
            ->add('lyrics', Field::TEXTAREA, [
                'rules' => 'max:5000'
            ])
            ->add('publish', Field::CHECKBOX);
    }
}

If you want to instantiate empty form without any fields, just skip passing --fields parameter:

php artisan make:form Forms/PostForm

Gives:

<?php

namespace App\Forms;

use Kris\LaravelFormBuilder\Form;

class PostForm extends Form
{
    public function buildForm()
    {
        // Add fields here...
    }
}

After that instantiate the class in the controller and pass it to view:

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller as BaseController;
use Kris\LaravelFormBuilder\FormBuilder;

class SongsController extends BaseController {

    public function create(FormBuilder $formBuilder)
    {
        $form = $formBuilder->create(\App\Forms\SongForm::class, [
            'method' => 'POST',
            'url' => route('song.store')
        ]);

        return view('song.create', compact('form'));
    }

    public function store(FormBuilder $formBuilder)
    {
        $form = $formBuilder->create(\App\Forms\SongForm::class);

        if (!$form->isValid()) {
            return redirect()->back()->withErrors($form->getErrors())->withInput();
        }

        // Do saving and other things...
    }
}

Alternative example:

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller as BaseController;
use Kris\LaravelFormBuilder\FormBuilder;
use App\Forms\SongForm;

class SongsController extends BaseController {

    public function create(FormBuilder $formBuilder)
    {
        $form = $formBuilder->create(SongForm::class, [
            'method' => 'POST',
            'url' => route('song.store')
        ]);

        return view('song.create', compact('form'));
    }

    public function store(FormBuilder $formBuilder)
    {
        $form = $formBuilder->create(SongForm::class);

        if (!$form->isValid()) {
            return redirect()->back()->withErrors($form->getErrors())->withInput();
        }

        // Do saving and other things...
    }
}

If you want to store a model after a form submit considerating all fields are model properties:

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Kris\LaravelFormBuilder\FormBuilder;
use App\SongForm;

class SongFormController extends Controller
{
    public function store(FormBuilder $formBuilder)
    {
        $form = $formBuilder->create(\App\Forms\SongForm::class);
        $form->redirectIfNotValid();
        
        SongForm::create($form->getFieldValues());

        // Do redirecting...
    }

You can only save properties you need:

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Kris\LaravelFormBuilder\FormBuilder;
use App\SongForm;

class SongFormController extends Controller
{
    public function store(FormBuilder $formBuilder, Request $request)
    {
        $form = $formBuilder->create(\App\Forms\SongForm::class);
        $form->redirectIfNotValid();
        
        $songForm = new SongForm();
        $songForm->fill($request->only(['name', 'artist'])->save();

        // Do redirecting...
    }

Or you can update any model after form submit:

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Kris\LaravelFormBuilder\FormBuilder;
use App\SongForm;

class SongFormController extends Controller
{
    public function update(int $id, Request $request)
    {
        $songForm = SongForm::findOrFail($id);

        $form = $this->getForm($songForm);
        $form->redirectIfNotValid();

        $songForm->update($form->getFieldValues());

        // Do redirecting...
    }

Create the routes

// app/Http/routes.php
Route::get('songs/create', [
    'uses' => 'SongsController@create',
    'as' => 'song.create'
]);

Route::post('songs', [
    'uses' => 'SongsController@store',
    'as' => 'song.store'
]);

Print the form in view with form() helper function:

<!-- resources/views/song/create.blade.php -->

@extends('app')

@section('content')
    {!! form($form) !!}
@endsection

Go to /songs/create; above code will generate this html:

<form method="POST" action="http://example.dev/songs">
    <input name="_token" type="hidden" value="FaHZmwcnaOeaJzVdyp4Ml8B6l1N1DLUDsZmsjRFL">
    <div class="form-group">
        <label for="name" class="control-label">Name</label>
        <input type="text" class="form-control" id="name">
    </div>
    <div class="form-group">
        <label for="lyrics" class="control-label">Lyrics</label>
        <textarea name="lyrics" class="form-control" id="lyrics"></textarea>
    </div>
    <div class="form-group">
        <label for="publish" class="control-label">Publish</label>
        <input type="checkbox" name="publish" id="publish">
    </div>
</form>

Or you can generate forms easier by using simple array

<?php

namespace App\Http\Controllers;

use Illuminate\Routing\Controller as BaseController;
use Kris\LaravelFormBuilder\FormBuilder;
use Kris\LaravelFormBuilder\Field;
use App\Forms\SongForm;

class SongsController extends BaseController {

    public function create(FormBuilder $formBuilder)
    {
        $form = $formBuilder->createByArray([
                        [
                            'name' => 'name',
                            'type' => Field::TEXT,
                        ],
                        [
                            'name' => 'lyrics',
                            'type' => Field::TEXTAREA,
                        ],
                        [
                            'name' => 'publish',
                            'type' => Field::CHECKBOX
                        ],
                    ]
            ,[
            'method' => 'POST',
            'url' => route('song.store')
        ]);

        return view('song.create', compact('form'));
    }
}
