Frameworks

Included frameworks

This document gives you quick examples of different layouts and form elements.

Most examples are displayed using Bootstrap 5 layout.
The other frameworks (Bootstrap 4, Bulma, Foundation, Material Design, Tailwind, and uiKit) use the same markup.

The fourth argument defines the framework when you instantiate your form.

// default Bootstrap 5 form
$form = new Form('form-name', 'horizontal', 'novalidate');

// Bootstrap 4
$form = new Form('form-name', 'horizontal', 'novalidate', 'bs4');

// Bulma
$form = new Form('form-name', 'horizontal', 'novalidate', 'bulma');

// Foundation
$form = new Form('form-name', 'horizontal', 'novalidate', 'foundation');

// Material form (Materialize)
$form = new Form('form-name', 'horizontal', 'novalidate', 'material');

// Tailwind
$form = new Form('form-name', 'horizontal', 'novalidate', 'material');

// uiKit
$form = new Form('form-name', 'horizontal', 'novalidate', 'uikit');

No framework

If your project is based on custom css or doesn't use any popular framework,
a minimal Bootstrap 5 CSS is provided in phpformbuilder/templates/assets/bootstrap5-phpfb/.

It includes only the strict minimum to build responsive forms.

Link this CSS file to your page and you can then create Bootstrap 5 forms without breaking anything from your design.

<head>
// link to the minimal Bootstrap 5 CSS
<link rel="stylesheet" href="/phpformbuilder/templates/assets/bootstrap5-phpfb/css/bootstrap5-phpfb.min.css">
</head>
<?php
// Then you can build your form
$form = new Form(\'my-form\', \'horizontal\', \'novalidate\');

Customize for other frameworks

Each framework has its specific markup and CSS classes. For example, some frameworks wrap radio buttons & checkboxes into their label, whereas others don't.

Bootstrap adds a CSS form-control class to the form elements, but other frameworks don't.

The options property of the form defines all these specificities, including responsive rows & columns., including responsive rows & columns.

The HTML code generated by PHP Form Builder can be easily customized for any framework:
Semantic-UI, Pure, Skeleton, UIKit, Milligram, Susy, ...

$custom_options = array(
    // options here
);
$form->setOptions($custom_options);

Layout

Horizontal forms

The horizontal forms display labels and fields in two responsive columns whose width you can define.

$form = new Form('my-form', 'horizontal', 'novalidate');

// 3 columns label, 9 columns field, breakpoint = small screens
$form->setCols(3, 9, 'sm');

$form->addInput('text', 'user-name', '', 'User Name', 'required');

<div class="row mb-3">
	<label for="user-name" class="col-sm-3 col-form-label">
		User Name <sup class="text-danger">* </sup>
	</label>
	<div class="col-sm-9">
		<input id="user-name" name="user-name" type="text" value="" required class="form-control">
	</div>
</div>

Vertical forms

In vertical forms, labels are displayed above the fields. Vertical forms don't use columns.

$form = new Form('my-form', 'vertical', 'novalidate');
$form->addInput('text', 'user-name', '', 'User Name', 'required');

<div class="bs5-form-stacked-element mb-3">
	<label for="user-name" class="form-label">
		User Name <sup class="text-danger">* </sup>
	</label>
	<input id="user-name" name="user-name" type="text" value="" required class="form-control">
</div>

Inline forms

Inline forms display labels and fields on the same line without containers.

To do this, create your form in horizontal mode and group your fields, or use input addons.

$form = new Form('my-form', 'horizontal', 'novalidate');
$form->setCols(-1, -1);
$form->addHeading('Elements grouped on the same line', 'h4');
$form->groupElements('user-firstname', 'user-name', 'submit-btn');
$form->addInput('text', 'user-firstname', '', '', 'placeholder=First name, required');
$form->addInput('text', 'user-name', '', '', 'placeholder=Name, required');
$form->addBtn('submit', 'submit-btn', 1, 'Submit', 'class=btn btn-primary');
$form->addHeading('Elements with addons', 'h4', 'class=mt-5');
$addon_html = '<button class="btn btn-primary" type="submit">Submit</button>';
$form->addAddon('search-input', $addon_html, 'after');
$form->addInput('text', 'search-input', '', '', 'placeholder=Search ..., required');

Elements grouped on the same line

Elements with addons

<h4>
	Elements grouped on the same line
</h4>
<div class="row mb-3">
	<div class="col-sm">
		<input id="user-firstname" name="user-firstname" type="text" value="" placeholder="First name" required class="form-control fv-group" aria-label="First name">
	</div>
	<div class="col-sm">
		<input id="user-name" name="user-name" type="text" value="" placeholder="Name" required class="form-control fv-group" aria-label="Name">
	</div>
	<div class="col-sm">
		<button type="submit" name="submit-btn" value="1" class="btn btn-primary">
			Submit
		</button>
	</div>
</div>
<h4 class="mt-5">
	Elements with addons
</h4>
<div class="row mb-3">
	<div class="col-sm">
		<div class="input-group has-addon-after">
			<input id="search-input" name="search-input" type="text" value="" placeholder="Search ..." required class="form-control" aria-label="Search ...">
			<button class="btn btn-primary input-group-btn phpfb-addon-after" type="submit">
				Submit
			</button>
		</div>
	</div>
</div>

Input groups

Input groups allow you to group several fields in the same row.

It is only possible in horizontal forms, which are the only ones to use a responsive layout with columns and rows.

$form = new Form('my-form', 'horizontal', 'novalidate');

// 2 columns label, 4 columns field, breakpoint = small screens
$form->setCols(2, 4, 'sm');

$form->groupElements('user-name', 'user-first-name');

$form->addInput('text', 'user-name', '', 'Name', 'required');
$form->addInput('text', 'user-first-name', '', 'First name');

<div class="row mb-3">
	<label for="user-name" class="col-sm-2 col-form-label">
		Name <sup class="text-danger">* </sup>
	</label>
	<div class="col-sm-4">
		<input id="user-name" name="user-name" type="text" value="" required class="form-control fv-group">
	</div>
	<label for="user-first-name" class="col-sm-2 col-form-label">
		First name
	</label>
	<div class="col-sm-4">
		<input id="user-first-name" name="user-first-name" type="text" value=""  class="form-control fv-group">
	</div>
</div>

Columns

To create a 2-column form, insert the html code in the appropriate places using the startRow(), startCol(), endRow(), endCol() functions.

$form = new Form('my-form', 'vertical', 'novalidate');

$form->startRow();
$form->startCol(6);

$form->addInput('text', 'user-name', '', 'Name', 'required');
$form->addInput('text', 'user-first-name', '', 'First Name', 'required');

$form->endCol();
$form->startCol(6);

$form->addInput('email', 'user-email', '', 'Email', 'required');
$form->addInput('tel', 'user-phone', '', 'Phone', 'required');

$form->endCol();
