我希望在一个单独的文件中定义全局变量，然后将其插入到我想要的任何位置，因此对于Laravel 4 + Blade，我做到了。
顶级文件example.blade.php：
@include('head')
@include('body')
head.blade.php
$STYLE_PATH_CSS="styleFolder/foundation/css"
$STYLE_PATH_JS="styleFolder/foundation/js"
$STYLE_PATH_JS_VENDOR="styleFolder/foundation/js/vendor"
<link rel="stylesheet" href=" <?php echo $STYLE_PATH_CSS ?>/normalize.css ">
<link rel="stylesheet" href=" <?php echo $STYLE_PATH_CSS ?>/foundation.css ">
<link rel="stylesheet" href=" <?php echo $STYLE_PATH_JS_VENDOR ?>/modernizr.js ">
body.blade.php
<script src="styleFolder/foundation/js/vendor/jquery.js"></script>
<script src="styleFolder/foundation/js/foundation.min.js"></script>
在那之前，它工作正常。然后，我希望再简化一次：用全局变量替换重复路径。所以，
variables_G.blade.php
<?php $STYLE_PATH_CSS="styleFolder/foundation/css" ?>
<?php $STYLE_PATH_JS="styleFolder/foundation/js" ?>
<?php $STYLE_PATH_JS_VENDOR="styleFolder/foundation/js/vendor" ?>
和新的head.blade.php
@include('variables_G.blade.php')
<link rel="stylesheet" href=" <?php echo $STYLE_PATH_CSS ?>/normalize.css ">
<link rel="stylesheet" href=" <?php echo $STYLE_PATH_CSS ?>/foundation.css ">
<link rel="stylesheet" href=" <?php echo $STYLE_PATH_JS_VENDOR ?>/modernizr.js ">
那么就找不到变量的值。错误信息：
Undefined variable: STYLE_PATH_CSS.
谁能帮我吗？
视图应该是愚蠢的，这也意味着您不应在一个视图内部创建变量以提供给另一个视图，也不应为视图提供过多的可重复性。
向Blade View提供全局变量并确保它们随时可用的最佳方法是使用View::share()：
View::share('STYLE_PATH_CSS', 'styleFolder/foundation/css');
View::share('STYLE_PATH_JS', 'styleFolder/foundation/js');
View::share('STYLE_PATH_JS_VENDOR', 'styleFolder/foundation/js/vendor');
您可以将其添加到composers.php文件并将其加载到您的app/start/global.php：
require app_path().'/composers.php';
