如何在Laravel Blade模板中设置变量

问题描述

我正在阅读Laravel刀片文档，但我不知道如何分配模板中的变量供以后使用.我无法执行{{ $old_section = "whatever" }}，因为那样会回显任何内容"，而我不希望那样.

I'm reading the Laravel Blade documentation and I can't figure out how to assign variables inside a template for use later. I can't do {{ $old_section = "whatever" }} because that will echo "whatever" and I don't want that.

我知道我可以做<?php $old_section = "whatever"; ?>，但这并不优雅.

I understand that I can do <?php $old_section = "whatever"; ?>, but that's not elegant.

在Blade模板中是否有更好，更优雅的方法?

Is there a better, elegant way to do that in a Blade template?

推荐答案

不建议在视图中进行操作，因此没有刀片标记.如果您确实想在刀片视图中执行此操作，则可以在编写时打开一个php标签，也可以注册一个新的刀片标签.只是一个例子:

It is discouraged to do in a view so there is no blade tag for it.If you do want to do this in your blade view, you can either just open a php tag as you wrote it or register a new blade tag. Just an example:

<?php
/**
 * <code>
 * {? $old_section = "whatever" ?}
 * </code>
 */
Blade::extend(function($value) {
    return preg_replace('/\{\?(.+)\?\}/', '<?php ${1} ?>', $value);
});
