laravel blade, how to append to a section
as mentioned before, I used @parent and it works fine for me. May be an example for extended title will helps:
master.blade.php
@section('title')
My Blog
@stop
<!doctype html>
<html>
<head>
@include('includes.head')
</head>
<body>
<div class="container-fluid">
<div id="main" class="row">
@yield('content')
</div>
</div>
</body>
</html>
includes/head.blade.php
<meta charset="utf-8">
<title>@yield('title')</title>
post.blade.php
@extends('master')
@section('title')
@parent
| {{$post->title }}
@stop
@section('content')
// Post Body here ..
@stop
Therefore, The Title will be rendered to be like this:
My Blog | My Post Title
Actually, this will render something like:
<title>
My Blog
| My Post Title
</title>
so you can use the section second parameter to set the values:
includes/head.blade.php
...
@section('title', 'My Blog')
...
post.blade.php
...
@section('title', '@parent | ' . $post->ar_name )
...
And this will render:
<title>My Blog | My Post Title</title>
So you will get rid of the lines inside the title,
Hope that's helps.
Note: This is used for Laravel 5.2, Not quite sure but as I remember, it works for Laravel 4 too.
The example in the documentation from Laravel website does indeed seem to be flawed, but I think it's a markdown parsing problem on the website, the same docs on github show the correct code:
In any case @parent does indeed work. The example in the docs should look like this:
@extends('layouts.master')
@section('sidebar')
@parent
<p>This is appended to the master sidebar.</p>
@stop
@section('content')
<p>This is my body content.</p>
@stop
A quick look in the Illuminate/View/Factory.php confirms what @parent does:
/**
* Append content to a given section.
*
* @param string $section
* @param string $content
* @return void
*/
protected function extendSection($section, $content)
{
if (isset($this->sections[$section]))
{
$content = str_replace('@parent', $content, $this->sections[$section]);
}
$this->sections[$section] = $content;
}
You can simply use @append...
@extends('layouts.master')
@section('sidebar')
<p>This is appended to the master sidebar.</p>
@append
@section('content')
<p>This is my body content.</p>
@stop
See here.
To understand how this works...
The compileStatements() method in the BladeCompiler calls the method compileAppend(), as you can see here:
/**
* Compile Blade Statements that start with "@"
*
* @param string $value
* @return mixed
*/
protected function compileStatements($value)
{
$callback = function($match)
{
if (method_exists($this, $method = 'compile'.ucfirst($match[1])))
{
$match[0] = $this->$method(array_get($match, 3));
}
return isset($match[3]) ? $match[0] : $match[0].$match[2];
};
return preg_replace_callback('/\B@(\w+)([ \t]*)(\( ( (?>[^()]+) | (?3) )* \))?/x', $callback, $value);
}
In turn, that inserts a call to appendSection() which looks like this:
/**
* Stop injecting content into a section and append it.
*
* @return string
*/
public function appendSection()
{
$last = array_pop($this->sectionStack);
if (isset($this->sections[$last]))
{
$this->sections[$last] .= ob_get_clean();
}
else
{
$this->sections[$last] = ob_get_clean();
}
return $last;
}
