blade.php方法将结果输出到表单 [英] blade.php method outputting it's result to the form
问题描述
我目前正在使用Laravel 4.2框架和Twitter引导程序设计一个网站.我已经设置了master.blade.php文件，该文件在每个页面的顶部都显示一个导航栏.
I am currently designing a website using the Laravel 4.2 framework and twitter bootstrap. I have set up my master.blade.php file which presents a navbar at the top of every page.
基本上，如果用户已登录，我希望显示的导航栏与未登录的用户具有不同的选项.因此，当用户登录时，请设置$_SESSION变量.
Basically if the user is logged in I want to display a navbar with different options than if a user is not logged in. Therefore when a user logs in I set the $_SESSION variable.
但是，当我在master.blade.php文件中使用{{session_start();}}时，会将1输出到我的网站.该如何解决?
However, when I use {{session_start();}} in my master.blade.php file, 1 is outputted to my website. How to fix this?

推荐答案
{{function()}}将转换为PHP echo，执行函数并显示返回值.
{{ function() }} will be translated to PHP echo, function is executed and return value printed.
在Laravel中，您不需要使用session_start()，因为Laravel具有内置的会话管理机制.
In Laravel you do not need to use session_start() as Laravel has builtin session management mechanism.
如果要使用其他菜单选项，则可以检查用户是否已登录并使用@if
If you want different menu options then you can check if user is logged in and use @if
@if(Auth::check())
link to Logout
@else
link to login
@endif
