If I have a layout called RightSideBar.blade.php in Laravel blade, one area yield('content') and the other yield('sidebar').
Is there a built in way to display a default partial if the view that is extending RightSideBar does not have a section('sidebar')?
I know you can pass a value by default, just wondering if there is a way to make default a partial.
Yes you can pass a default
Looking at the documentation
#yield('sidebar', 'Default Content');
Which basically puts a default output when the child template does not have #section('sidebar')
Most of the time we want multiple line default content, we can use this syntax:
#section('section')
Default content
#show
For example I have this in the template file:
#section('customlayout')
<article class="content">
#yield('content')
</article>
#show
You can see the difference between #show and #stop/#endsection: the above code is equivalent to the one below:
#section('customlayout')
<article class="content">
#yield('content')
</article>
#stop
#yield('customlayout')
In the other view files I can either set the content only:
#section('content')
<p>Welcome</p>
#stop
Or I can also set a different layout:
#section('content')
<p>Welcome</p>
#stop
#section('defaultlayout')
<div>
#yield('content')
</div>
#stop
The #stop is equivalent as the #endsection.
Although the docs specifies a default only as a string you can in fact pass a view
#yield('sidebar', \View::make('defaultSidebar'))
Laravel 5.2 added a #hasSection directive that checks if a section is defined in a view.
It's not mentioned in 5.3 or 5.4 docs for some reason.
#hasSection('sidebar')
#yield('sidebar')
#else
#yield('default-sidebar')
#endif
Tested in Laravel 8:
#yield can have default content as a second parameter. It can either be a string or a view file
// user-layout.blade.php
#yield('header', View::make('layouts.header'))
You can now override this "header" with section
#section('header')
<div>New Header</div>
#endsection
//// OR - you can also pass a view file as a second parameter //////
#section('header', View::make('layouts.new-header'))

This must be really simple, but since I’m new to Laravel, I’m having difficulties on finding this feature on documentation or in stackoverflow.
I’m going to try to build a very simple example to try to show what I want.
Let’s say I have a file called data.blade.php
#php
$myVariable = 'xyz';
#endphp
Then, I have my layout template file, called: home.blade.php
#extends('data.blade')
#section('content')
#php
echo $myVariable;
#endphp
#endsection
When I try to do this, it returns me an error:
Undefined variable $myVariable (etc)
How can I use a variable defined in another blade file? I used extends to exemplify, but I´m not sure if that is the right architecture.
Can anyone point me to the right way of accomplishing this?
Thanks!
you are extending data.blade.php and this file need to have some element to serve as template and be extended.
You can take any html5 file and rename this as template.blade.php, but where you want to render a section in your template must have a yield('section-name').
Make a new app.blade.php should look like this
<html>
<head>
<title>App Name - #yield('title')</title>
</head>
<body>
#section('sidebar')
This is the master sidebar.
#show
<div class="container">
#yield('content')
</div>
</body>
</html>
Then, in your home.blade.php
#extends('layouts.app')
#section('title', 'Page Title')
#section('sidebar')
#parent
<p>This is appended to the master sidebar.</p>
#endsection
#section('content')
#include(data)
{{$myVariable}}
<p>This is my body content.</p>
#endsection
From Laravel Doc
I'am new to Laravel I just want to know the difference between #extends and #include
#extends('tempalate')
can I use #include to add template file in my laravel project.
#include('tempalate')
To simply put it:
Using #include('') function you are including or adding an existing file.
Using #extends('') your are sending a portion of your file to the extended file.
Which is usually wrapped inside a #section('') function.
As per Laravel Documentation:
Blade's #include directive allows you to include a Blade view from
within another view. All variables that are available to the parent
view will be made available to the included view:
<div>
#include('shared.errors')
<form>
<!-- Form Contents -->
</form>
</div>
When defining a child view, use the Blade #extends directive to
specify which layout the child view should "inherit". Views which
extend a Blade layout may inject content into the layout's sections
using #section directives. Remember, as seen in the example above, the
contents of these sections will be displayed in the layout using
#yield:
<!-- Stored in resources/views/child.blade.php -->
#extends('layouts.app')
#section('title', 'Page Title')
#section('sidebar')
#parent
<p>This is appended to the master sidebar.</p>
#endsection
#section('content')
<p>This is my body content.</p>
#endsection
Laravel -> Blade Templates -> Including Subviews
In Laravel, there are different ways of using sections:
#yield('section1') // Filled in by child view
#section('section2')
// Default content, can be overwritten by child
// Different ways of closing the section
#endsection|stop|show|append
Who can tell me what the exact difference is between all of these?
Accoding to this, #stop and #endsection might be the same. (with one having been deprecated, but not anymore)
#endsection and #stop are the same and indicate the end of a section.
The section is not actually rendered on the page until you do #yield('sectionname')
In contrast, #show is equivalent to
#stop
#yield('sectionname')
i.e. it stops and immediately renders the section at that part of the page.
#append is basically equivalent to:
//FileA.blade.php
#section('sectionname')
... content
#stop
//FileB.blade.php
#extends('fileA')
#section('sectionname')
#parent
... more content after content
#stop
Here's some relevant source code:
protected function compileStop() {
return '<?php $__env->stopSection(); ?>';
}
protected function compileEndsection() {
return '<?php $__env->stopSection(); ?>'; //Same code
}
protected function compileShow() {
return '<?php echo $__env->yieldSection(); ?>';
}
Yield section just stops the current section and yields its contents.
I might be late in the party. But in Laravel 7.x series, there is no mention of "#stop" and "#append".
Q: Difference between #endsection and #show
#endsection directive just tells the blade engine where the section actually ends. And to show that section you need to use the #yield directive. If you don't yield that section blade won't show it after rendering the view.
For example in layout view:
<!-- layout -->
<body>
#section('content')
Some Content
#endsection
</body>
The above code has no meaning, of course we have defined a section. But it won't show up in the view to the client. So we need to yield it, to make it visible on the client. So lets yield it in the same layout.
<!--layout-->
<body>
#section('content')
Some content
#endsection
#yield('content')
</body>
Now the above code has some meaning to the client, because we have defined a section and told the Blade engine to yield it in the same layout.
But Laravel provides a shortcut to that, instead of explicitly yielding that section in the same layout, use the #section - #show directive pairs. Therefore the above code can be written as follows:
<!--layout-->
<body>
#section('content')
Some content
#show
</body>
So #show is just a compacted version of #endsection and #yield directives.
I hope I made everything clear. And one more thing, in laravel 7.x to append the content in the section, #parent directive is used.
Found it in quora
#show has similar functionality like #yield but you can use it for more things. When you declare #yield in your layout view you can set default value as well.
app.blade.php
#yield('title', 'Default Title')
and in your child view you can change the title
user.blade.php
#section('title', 'Custom Title')
However, you can set only string for default value in case of #yield. If you want to use some part of html content as a default part, you should use #show
app.blade.php
#section('some_div')
<h1>Default Heading1</h1>
<p>Default Paragraph
<span>Default Span</span>
</p>
#show
in your child view
#section('some_div')
<h1>Custom Heading1</h1>
<p>Custom Paragraph
<span>Custom Span</span>
</p>
#endsection
also you can use both default content and custom content together. just include #parent
#section('some_div')
#parent
<h1>Custom Heading1</h1>
<p>Custom Paragraph
<span>Custom Span</span>
</p>
#endsection
I use the Bladetemplate of Laravel. Is there a way to set different header for different views with only one include in master.blade.php?
master.blade.php
#include("elements.header")
#yield('content')
#section("footer")
#show
view.blade.php
#extends("layouts.master")
#section("title")
#stop
#section("content")
#include("elements.error")
#section("footer")
#include("elements.footer")
#stop
If you want to include different header templates for different views, there is no need to include anything from your layout. Instead, include the proper header template into a separate section in your views and then display that section in the master template:
master.blade.php
#yield('header')
#yield('content')
viewA.blade.php
#extends("layouts.master")
#section('header')
#include('headerA')
#stop
#section('content')
view content
#stop
viewB.blade.php
#extends("layouts.master")
#section('header')
#include('headerB')
#stop
#section('content')
view content
#stop
This way, each of your views includes different header templates into the header section that will be later displayed in master layout with #yield('header').
In your main layout
<title>#yield('title','Home')</title>
Then In your views Just call
#section('title','My View 1')
#section('title','My View 2')
The second parameter in yield is the default if none defined.
I have two page on Laravel.
I can easily extend this layout in another blade partial to get a working modal with a header, content, and footer which I can embed using #extends('master').
My problem is:
The first page is using header1.blade.php.
And second page is using header2.blade.php.
On master.blade.php is my master page.
<body>
#include('partials.header1')
#yield('content')
#include('partials.footer')
</body>
On index.blade.php is using master.blade.php is master page with extends('master.blade.php).
On listnews.blade.php have same master page.
I want at listnews.blade.php using partials.header2.
Have any way to do this?
As an alternative to #lewis4u's answer you can use the #section directve.
This way you can define the default header to be used but you can change it whenever you need to.
Firstly, change your master.blade.php file to be:
<body>
#section('header')
#include('partials.header1')
#show
#yield('content')
#include('partials.footer')
</body>
Then in your listnews.blade.php file just add another section after the extends:
#section('header')
#include('partials.header2')
#endsection
Hope this helps!
