Laravel Blade Template Engine for Bono PHP Framework

Note: BonoBlade also use Blade templating for partial view

Installation

Add this line to your composer.json file

"require": {
    "krisanalfa/bono-blade": "~0.6.*"
},

Configuration

Add these lines to your configuration file

'bono.providers' => array(
    '\\KrisanAlfa\\Blade\\Provider\\BladeProvider'
),

// Bono Themeing
'bono.theme' => array(
    'class' => '\\KrisanAlfa\\Theme\\BladeTheme', // You can use another theme that extends from bono
),

// Bono Partial (segment of template)
'bono.partial.view' => '\\KrisanAlfa\\Blade\\BonoBlade',

If you want to change layout file name, templates path, or cache path, you can add options in your provider like this

'bono.providers' => array(
    '\\KrisanAlfa\\Blade\\Provider\\BladeProvider' => array(
        'templates.path' => array('pathToTemplatesPath'), // Default is array('../templates')
        'cache.path' => 'pathToCachePath',                // Default is '../cache'
        'layout' => 'customLayoutName',                   // Default is 'layout'
    ),
),

Note: You may use any other theme based on BladeTheme, such as blade foundation. Or you can create your own theme.

Basic usage

use Bono\App;

$app = App::getInstance();

$app->get('/', function () use ($app) {
    $app->render('yourTemplateName', array('var' => 'value'));
});

Layout example

<!-- myLayout.blade.php -->
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>@yield('title', 'Devel')</title>
</head>

<body>
    <div>
        @yield('content')
    </div>
</body>
</html>

Template example

<!-- myTemplate.blade.php -->
@section('title')
New Title
@endsection

@section('content')
<h1>Hello, {{ $name }}!</h1>
@endsection

Rendering template

Simply, you can render your template by call render function in \Bono\App instance.

use Bono\App;

$app = App::getInstance();

$app->get('/', function () use ($app) {
    $app->view->setLayout('myLayout');
    $app->render('myTemplate', array('name' => 'Krisan Alfa Timur'));
});

Note: Be sure you're not adding .blade.php or your template will not found

Result

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>New Title</title>
</head>

<body>
    <div>
        <h1>Hello, Krisan Alfa Timur!</h1>
    </div>
</body>
</html>

Rendering a page without layout

use Bono\App;

$app = App::getInstance();

$app->get('/', function () use ($app) {
    // This method is same with $app->theme->partial($templateName, $data)
    $app->view->display('myTemplateWithoutLayout', array('name' => 'Krisan Alfa Timur'));
});

Working with sections

<!-- Layout, filename: myCustomLayout -->
<html>
    <body>
        @section('sidebar')
            This is the master sidebar.
        @show

        <div class="container">
            @yield('content')
        </div>
    </body>
</html>

<!-- Template -->
@extends('myCustomLayout')

@section('sidebar')
    @parent

    <p>This is appended to the master sidebar.</p>
@stop

@section('content')
    <p>This is my body content. Appended to the container.</p>
@stop

Note that views which extend a Blade layout simply override sections from the layout. Content of the layout can be included in a child view using the @parent directive in a section, allowing you to append to the contents of a layout section such as a sidebar or footer.

Sometimes, such as when you are not sure if a section has been defined, you may wish to pass a default value to the @yield directive. You may pass the default value as the second argument:

@yield('content', '<p>Default</p>')

Including sub-views

@include('view.name')

You may also pass an array of data to the included view:

@include('view.name', array('some'=>'data'))

Overwriting sections

By default, sections are appended to any previous content that exists in the section. To overwrite a section entirely, you may use the overwrite statement:

@section('test')
   one
@stop
@section('test')
   two
@stop
@yield('test')

The outpur is:

one

But if you change the second @stop to an @overwrite.

@section('test')
   one
@stop
@section('test')
   two
@overwrite
@yield('test')

Then the following is output.

two

@overwrite - End a Section and Overwrite it.
@stop - Stopping Injecting Content Into a Section.
@show - Yielding the Current Section in a Blade Template.
@append - Stopping Injecting Content into a Section and Appending It.

Extends template to be reuseable

<!-- listTemplate -->
@section('header')
My sexy header
@endsection

<div class="container">
    @section('body')
        {{-- some other controll structure to make your page happens --}}
    @endsection

    @section('action')
        <div class="action">
            <button>Edit</button>
            <button>Update</button>
        </div>
    @endsection
</div>

@section('footer')
My shiny footer
@endsection

<!-- Another template that extends listTemplate -->

@extends('listTemplate')

@section('body')
    {{-- some other controll structure to make your page happens --}}
    {{-- some kind that make this page unique --}}

    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Rerum eligendi, totam velit earum assumenda optio accusantium magni est maiores ad inventore expedita nisi minus autem, porro adipisci cupiditate in iure!</p>

    <div class="blue">
        Some bluish content
    </div>
@overwrite

Based on this case, your body section will be overriden by lorem ipsum and bluish content.

Other blade control structures

Echoing data

Hello, {{{ $name }}}.

The current UNIX timestamp is {{{ time() }}}.

Echoing data after checking for existence

Sometimes you may wish to echo a variable, but you aren't sure if the variable has been set. Basically, you want to do this:

{{{ isset($name) ? $name : 'Default' }}}

However, instead of writing a ternary statement, Blade allows you to use the following convenient short-cut:

{{{ $name or 'Default' }}}

Displaying raw text with curly braces

If you need to display a string that is wrapped in curly braces, you may escape the Blade behavior by prefixing your text with an @ symbol:

@{{ This will not be processed by Blade }}

Of course, all user supplied data should be escaped or purified. To escape the output, you may use the triple curly brace syntax:

Hello, {{{ $name }}}.

If you don't want the data to be escaped, you may use double curly-braces:

Hello, {{ $name }}.

Note: Be very careful when echoing content that is supplied by users of your application. Always use the triple curly brace syntax to escape any HTML entities in the content.

If statements

@if (count($records) === 1)
    I have one record!
@elseif (count($records) > 1)
    I have multiple records!
@else
    I don't have any records!
@endif

@unless (App::getInstance()->auth->check())
    You are not signed in.
@endunless

Note: Method @unless is used when you want to write @if(! functionReturnBool())

Loops

@for ($i = 0; $i < 10; $i++)
    The current value is {{ $i }}
@endfor

@foreach ($users as $user)
    <p>This is user {{ $user->id }}</p>
@endforeach

@while (true)
    <p>I'm looping forever.</p>
@endwhile

Comments

##Extending blade

use Bono\App;

$app = App::getInstance();

$app->view->extend(function($view, $compiler) {
    $pattern = $compiler->createMatcher('datetime');

    return preg_replace($pattern, '$1<?php echo $2->format("m/d/Y H:i:s"); ?>', $view);
});

Now you can use @dateTime($dateValue) to get your datetime value.

The createPlainMatcher method is used for directives with no arguments like @endif and @stop, while createMatcher is used for directives with arguments.

use Bono\App;

$app = App::getInstance();

$app->view->extend(function($view, $compiler) {
    $pattern = $compiler->createPlainMatcher('pre');

    return preg_replace($pattern, '<pre>', $view);
});

$app->view->extend(function($view, $compiler) {
    $pattern = $compiler->createPlainMatcher('endpre');

    return preg_replace($pattern, '</pre>', $view);
});

Now you can use @pre and @endpre whenever you want to print_r() your value. Just like this:

@pre
print_r($myPrettyPrintVariable)
@endpre

Setting the content tags blade uses

You know that blade uses {{ and }} to specify content to be output, but this conflicts with Mustache or some other library you're using. If you want to use other tags, you can use setContentTags method. Let's say you want to use [% and %] for your tags.

use Bono\App;

$app = App::getInstance();

$app->view->setContentTags('[%', '%]');

Then your template can contain code like.

The value of $variable is [% $variable %].

You can also pass a third argument as true to indicate you're setting the tags to escape content.

use Bono\App;

$app = App::getInstance();

$app->view->setContentTags('[%', '%]', true);

Then instad of using {{{ and }}} you can use [-% and %-].

The HTML tags inside this value would be escaped [%- $variable -%].

Note: You must call setContentTags method before using view. The best options is: make a Provider that preparing all of your Blade customization.
