我目前正在使用初学者网站： https://github.com/andrewelkins/Laravel-4-Bootstrap-Starter-Site
我将博客文章中的任何html转换为文本。例如，tag hi标签（应该在标签周围有括号）在div中转换为hi。我希望它只在像div这样的标签中输出hi 这是控制器

先谢谢你的帮助！

这里有两个解决方案：
HTML::decode()对其进行解码即可。因此，对于编码的帖子内容，您可以在视图HTML::decode($post->content)中书写。答案 1 :(得分：1)
这是因为你正在使用的视图中的输出正在通过刀片花括号{{{ }}}运行htmlentities，意思是;
<div>hi </div>
转换为
<<div>hi </div>
要防止这种情况并在帖子中允许html，请将{{{ }}}更改为{{ }}。
