Laravel 5 Framework Learning Blade Introduction, Laravelblade

In multiple pages we may contain the same content, such as the file header, linked CSS or JS. We can use the layout file to complete this function.

Let's create a new layout file, such as views/layout.blade.php

  
 
    Document  
 
        @yield (' content ')  

We created a puzzled structure, introduced the bootstrap, note that @yield is the blade layout placeholder, the future of our page content will be populated here, modified about.blade.php

@extends (' layout ') @section (' content ')  
About {{$first}} {{$last}}
@stop

The above code indicates that we use the layout file layout.blade.php and then add content to the contents section.

Add in routes.php:

Route::get (' About ', ' pagescontroller@about '); Route::get (' Contact ', ' pagescontroller@contact ');

Add in pagescontroller.php:

  Public Function Contact () {    return view (' Pages.contact ');  }

New View pages/contact.blade.php

@extends (' layout ') @section (' content ')  
Contact me!
@stop

Check it out!

In the layout file we can add multiple @yield, such as adding @yield (' footer ') to the layout.blade.php:

  
 
    Document  
 
        @yield (' content ')    @yield (' footer ')

For example, there is a script in contact.blade.php that can be placed in this section.

@extends (' layout ') @section (' content ')  
Contact me!
@stop @section (' footer ')  @stop

Access to the contact will have a dialog box, and about is still a normal display

Use @if to judge

@extends (' layout ') @section (' content ')  @if ($first = ' Zhang ')    
Hello, Zhang
  @else    
Hello, nobody.
  @endif @stop

can also be equated with the same @unless if!, and @foreach.

  Public function about ()  {    $people = [      ' Zhang San ',      ' Li si ',      ' Wang Wu '    ];    Return view (' Pages.about ', compact (' People '));  } @extends (' layout ') @section (' content ')  
Person:
  
 
  
  

   
   
      @foreach ($people as $person)      
  
   
   
{{$person}}
    @endforeach  
 
  
  
 @stop

In one case, the data might be from the database, and the collection might be empty, like this:

Copy the Code code as follows:
$people = [];

To handle this situation, add @if processing

@extends (' layout ') @section (' content ')  @if (count ($people))    
Person:
    
 
  
  

   
   
        @foreach ($people as $person)        
  
   
   
{{$person}}
      @endforeach    
 
  
  
  @endif  
Other Info
@stop

That ' s better.
