Laravel Dynamic Form

This package lets you dynamically create forms for a Laravel application that can be easily filled out by a user.

I created this package to have better control over user form pages, questions and options.

Note: both the package and readme are still a work in progress

Install

$ composer require taylornetwork/laravel-dynamic-form

Setup

Run migrations

$ php artisan migrate

Models

All models are in the namespace TaylorNetwork\DynamicForm\Models

Form

The Form model allows you to define a form key and title and will provide all related models below.

Page

The Page model allows you to define pages on the form. This can be useful if you have a lot of questions to ask the user. Forms need at least 1 page.

Pages are numbered automatically when you use the addPage method (see Usage below)

Pages can have a title that will be displayed to the user.

Question

The Question model is the actual question that will be shown to the user. You can specify the a few different question types.

Currently supported types

text (default)
textarea
select
select multiple
select multiple taggable (select multiple but can include user defined values)

Option

The Option model is only used if the question type is one that includes select. It allows you to set options to be used for the select controls

Usage

For example you want to create a multiple page form that asks the user about themselves and their home.

Create a new form

Form::create([ 'key' => 'user-info', 'title' => 'User Information Form' ]);

Fetch a form by key

You can use the fetch method on the Form model to fetch a form by key or you can use the get_form_data helper function.

Form::fetch('user-info');

get_form_data('user-info');

Add a page

Use the addPage method to add a new page to a form. Forms need at least 1 page. The addPage method will automatically increment the page numbers. It accepts an optional parameter that is the title of the page.

Form::fetch('user-info')->addPage('Information about you');

Form::fetch('user-info')->addPage();

Add questions

Use the addQuestion method to add a question to a page of a form.

Form::fetch('user-info')->page(1)->addQuestion('What is your name?');

Form::fetch('user-info')->page(1)->addQuestion('What is your email address?');

Form::fetch('user-info')->page(1)->addQuestion('Tell us something interesting about you?', 'textarea');

Add questions with options

Basic options:

For basic options that the values to pass back are the same as the text shown to the user, use the addOptions method and pass an array to a question.

Form::fetch('user-info')->page(1)->addQuestion('Are you the home owner?', 'select')->addOptions([ 'Yes', 'No' ]);

Form::fetch('user-info')->page(1)->addQuestion('What colours are in your home?', 'select multiple taggable')->addOptions([ 'Yellow', 'Blue', 'Red' ]);

Options with different values:

For options that the values passed back are different than the text shown to the user, use the addOption method and pass the text as the first parameter and the value as the second.

The addOption method returns an instance of the Option model so you cannot chain multiple together.

$question = Form::fetch('user-info')->page(1)->addQuestion('What rooms need work?', 'select multiple');

$question->addOption('Bathroom', 'BATH');
$question->addOption('Living Room', 'LVRM');
$question->addOption('Bedroom', 'BDRM');
$question->addOption('Basement', 'BSMT');

VueJS Setup

If you want to use the VueJS modal included

Install required NPM dependencies

$ npm install --save vue-select sweetalert2

Publish VueJS component

$ php artisan vendor:publish --tag=form-components

Add the following line to your resources/js/app.js somewhere after window.Vue = require('vue');

Vue.component('dynamic-form', require('./components/DynamicForm.vue').default);

VueJS Usage

The Vue modal has 3 required props

id: The modal ID, used to open the modal
form-data: The actual form data, you can use the get_form_data() helper
post-route: The route to post the saved data to

When the data is submitted the component will use make an axios POST request to the uri from post-route.

The POST data will be an object with keys being the id of the question and the value being the data entered. If using select multiple this will be an array if more than one item is selected.

Basic Example

<button class="btn btn-outline-secondary" data-toggle="modal" data-target="#dynForm">Open Modal</button>

<dynamic-form id="dynForm" 
				 :form-data="{{ get_form_data('user-info') }}" 
				 post-route="{{ route('api.dynamic.form.store') }}">
</dynamic-form>

Note: When passing the form data to the Vue component be sure to include the : to bind the data. T

Example POST Data

Based on example above.

{
	1: 'John Doe',
	2: 'johndoe@example.com',
	3: 'John Doe is not my real name.',
	4: 'Yes',
	5: [ 
			'Blue',
			'Red'
		],
	6: 'BDRM'
}
