blade

Laravel 框架中的 Blade 模板引擎，很好用，但是在官方文档中有关 Blade 的介绍并不详细，有些东西没有写出来，而有些则是没有说清楚。比如，使用中可能会遇到这样的问题： 1. @yield 和 @section 都可以预定义可替代的区块，这两者有什么区别呢？ 2. @section 可以用 @show , @stop , @overwrite 以及 @append 来结束，这三者又有什么区别呢？ 本文试对这些问题做一个比较浅显但是直观的介绍。 @yield 与 @section 首先， @yield 是不可扩展的 ，如果你要定义的部分没有默认内容让子模板扩展的，那么用 @yield($name, $default) 的形式会比较方便，如果你在子模板中并没有指定这个区块的内容，它就会显示默认内容，如果定义了，就会显示你定义的内容。非此即彼。 与之相比， @section 则既可以被替代，又可以被扩展 ，这是最大的区别。比如： 代码 如下: {{-- layout.master --}} @yield('title','默认标题') @section('content') 默认的内容 @show 代码如下: {{-- home.index --}} @extends('layout.master') @section('title') @parent 新的标题 @stop

In Laravel 5.0.27 I am including a view with with a variable and the following code: @include('layouts.article', [ 'mainTitle' => "404, page not found", 'mainContent' => "sorry, but the requested page does not exist :(" ]) and I get the following error... FatalErrorException syntax ... error, unexpected ',' I've narrowed down that the error is solely from the "(" in the "mainContent" variable string, and when I remove the "(" the error disappears and everything runs fine.

I am developing a Laravel(5.2.29) project in Windows environment and testing it on Chrome browser. I have made some changes on a Blade file using atom text editor and then refreshed my page and noticed that suddenly it has stopped reflecting the changes (it's loading the old Blade file). I've tried the following: Restarted the browser Clearing browser cache Running php artisan cache:clear Running composer dumpautoload Deleting the Blade file (and got a view not found error). Then created a new Blade file with the same name, with no content and refreshed the page. No matter what, the code

Laravel blade drop down list class attribute not working. I cannot find any reference to class or assigning attributes to select / drop-down lists in the documentation. http://www.laravel.com/docs/html#drop-down-lists Examples tried: {{ Form::select('product_id', $productList, array('class'=>'form-control')) }} {{ Form::select('product_id', $productList, $attributes = array('class'=>'form-control')) }} Both return the same html but without the class attribute: <select id="product_id" name="product_id"> ...

I would like to know what would be the best way to display a default value if the given value is not set. I have the following in a blade file (I can not guaranty that the key is set, it depends on a multitude of factors). {{ $foo['bar'] }} I would know if the following is the best way to go about it, {{ (isset($foo['bar']) ? $foo['bar'] : 'baz' }} or is there a better way to do this? Thanks :) Use php's null coalesce operator: {{ $variable ?? "Default Message" }} Removed as of Laravel 5.7 With Laravel 4.1-5.6 you could simply do it like this: {{ $variable or "Default Message" }} It's the same
