README

HTML Component extends the functionality of Illuminate\Html with the extra functionality to including a chainable Form and Table builder. These set of functionality are the backbone in allowing extensions in Orchestra Platform to attach action to any existing form or table.

Version Compatibility

Installation

To install through composer, run the following command from terminal:

composer require "orchestra/html"

Configuration

Next add the service provider in config/app.php.

'providers' => [

    // ...

    Orchestra\Html\HtmlServiceProvider::class,
],

Aliases

You might want to add the following to class aliases in config/app.php:

'aliases' => [

    // ...

    'Form' => Orchestra\Support\Facades\Form::class,
    'HTML' => Orchestra\Support\Facades\HTML::class,
    'Table' => Orchestra\Support\Facades\Table::class,
],

Usage

Orchestra\Html\HtmlBuilder is a small improvement from Illuminate\Html\HtmlBuilder.

Advise to use this only when manipulating HTML outside of view, otherwise it's better (and faster) to use html.

Create HTML

Create a HTML tag from within your libraries/extension using following code:

return HTML::create('p', 'Some awesome information');

Will return <p>Some awesome information</p>.

You can customize the HTML attibutes by adding third parameter.

return HTML::create('p', 'Another awesomeness', ['id' => 'foo']);

Will return <p id="foo">Another awesomeness</p>.

Raw HTML Entities

Mark a string to be excluded from being escaped.

return HTML::link('foo', HTML::raw('<img src="foo.jpg">'));

Will return <a href="foo"><img src="foo.jpg"></a>.

This also can be dynamically done via.

return HTML::link('foo', HTML::image('foo.jpg'));

Decorate HTML

Decorate method allow developer to define HTML attributes collection as HTML::attributes method, with the addition of including default attributes array as second parameter.

return HTML::decorate(['class' => 'foo'], ['id' => 'foo', 'class' => 'span5']);

Will return array('class' => 'foo span5', 'id' => 'foo');.

It also support replacement of default attributes if such requirement is needed.

return HTML::decorate(['class' => 'foo !span5'], ['class' => 'bar span5']);

Will return array('class' => 'foo bar');, note that span5 is excluded when we give !span5 in the first parameter.

Forms

Creating forms couldn't be any easier using Orchestra's HTML package. Let's get started.

Creating a new Form

To create a new form, use the Form::of() method. The first parameter is simply a string to define what the form is for:

return Form::of('users');

Form Attributes

To customize your forms attributes, call the attributes($attributes) method on the FormGrid instance:

return Form::of('users', function ($form) {
    $attributes = [
        'method' => 'PATCH',
        'id'     => 'user-login-form',
        'class'  => 'form-horizontal',
    ];

    $form->attributes($attributes);
});

Specifying the Form layout

To specify the layout of the form, call the layout($view) method on the FormGrid instance:

return Form::of('users', function ($form) {
    $form->layout('layouts.form');
});

Adding Fields

To add fields to our form, we'll pass in a closure into the second parameter, and call the fieldset() method off of the injected FormGrid. Here's an example:

return Form::of('users', function ($form) {
    $form->fieldset(function ($fieldset) {
        $fieldset->control('input:text', 'username');
        $fieldset->control('input:email', 'email');
        $fieldset->control('input:password', 'password');
    });
});

Available Fields

// A text field
$form->control('input:text', 'name');

// A password field
$form->control('input:password', 'name');

// A file field
$fieldset->control('input:file', 'name');

// A textarea filed
$form->control('textarea', 'name');

// A select field
$form->control('select', 'name')
    ->options(['one', 'two', 'three']);

Adding Labels to Fields

To add a label onto a form control, use the method label():

$form->fieldset(function ($fieldset) {
    $form->control('input:text', 'username')
        ->label('Username');

    $form->control('input:email', 'email')
        ->label('Email');

    $form->control('input:password', 'password')
        ->label('Password');
});

Adding Default Values to Fields

To add a default value to the field, use the method value() on the form control:

$form->fieldset(function ($fieldset) {
    $form->control('input:text', 'username')
        ->label('Username')
        ->value(Auth::user()->username);

    $form->control('input:email', 'email')
        ->label('Email')
        ->value(Auth::user()->email);

    $form->control('input:password', 'password')
        ->label('Password');
});

Changing the submit button label

To change the submit button label, modify the FormGrid property submit like so:

return Form::of('users', function ($form) {
    // The form submit button label
    $form->submit = 'Save';

    $form->fieldset(function ($fieldset) {
        $form->control('input:text', 'username');
        $form->control('input:email', 'email');
        $form->control('input:password', 'password');
    });
});

Customizing the form control attributes

To customize the form controls attributes, call the attributes($attributes) method on the control:

$attributes = [
    'placeholder' => 'Enter your username',
    'class'       => 'form-control',
];

$form->control('input:text', 'username')
    ->attributes($attributes);

Customizing the form control itself

$form->control('input:email', 'email', function ($control) {
    $control->field(function ($row) {
        return "<input type='email' name="email" value='$row->email'>";
    });
});

You could also create a Renderable class:

use Illuminate\Contracts\Support\Renderable;

class EmailAddressField implements Renderable
{
    public function __construct($name, $value)
    {
        $this->name = $name;
        $this->value = $value;
    }

    public function render()
    {
        return sprintf('<input type="email" name="%s" value="%s">', $this->name, $this->value);
    }
}

And you can simply register it via:

$form->control('input:email', 'email', function ($control) {
    $control->field(function ($row) {
        return new EmailAddressField('email', $row->email);
    });
});

Displaying your form

To display your form, simply display it in your view with unescaped blade tags:

public function index()
{
    $form = Form::of('users', function ($form) {
        $form->fieldset(function ($fieldset) {
            $form->control('input:text', 'username');
            $form->control('input:email', 'email');
            $form->control('input:password', 'password');
        });
    });

    return view('index', compact('form'));
}

// In index.blade.php

{!! $form !!}
