how to echo strings and variable in laravel 5.1 blade
提问by Sajjad
I am using this code inside my PHPfile:
我在我的PHP文件中使用此代码：
university.blade.php
{{ url( $universities->universityName.'/students') }}" >
The problem is that displays just http://localhost:8000/students, not the value of variable. So what is the solution?
问题是只显示http://localhost:8000/students，而不是变量的值。那么解决方案是什么？

Probably $universities->universityNameis empty
大概$universities->universityName是空的
Lets assume your controller looks like this:
假设您的控制器如下所示：
<?php namespace App\Http\Controllers
use App\University; // I assume this is your model
class UniversityController extends Controller{
public function index()
{
$universities = Univeristy::all();
return view('universities', compact('universities'));
}
}
Then later in your universities.blade.php
然后在你的 universities.blade.php
<a href="{!! url("{$univerisity->universityName}/students") !!}">Students</a>
or you can check if $universities->universityNameis empty, if it doesn't print the URL means its empty.
或者你可以检查是否$universities->universityName为空，如果它不打印 URL 意味着它是空的。
@if(!$universities || !$universities->universityName)
<a href="{!! url("{$univerisity->universityName}/students") !!}">Students</a>
@endif

As it seems you're passing some parameter in the url.
看来您正在 url 中传递一些参数。
I assume that you want to print those parameter in your view
我假设您想在视图中打印这些参数
Here i wrote an example route, controller with view for your understanding.
在这里，我写了一个示例路线，带有视图的控制器以供您理解。
Step 1 :Write a route method
第 1 步：编写路由方法
Route::get('get/{id}', 'publicController@get');
Step 2 :Write a function inside your controller
第 2 步：在控制器中编写一个函数
public function get($id)
{
return view('get')->with('id', $id);
}
Now you're returning the parameter that you passed to the view
现在您要返回传递给视图的参数
Step 3 :Show in your View
第 3 步：在您的视图中显示
Inside your view you can simply echo it using
在您的视图中，您可以简单地使用
{{ $id }}
So If you have this in your url
所以如果你的网址中有这个
http://localhost/yourproject/get/14
http://localhost/yourproject/get/14
Then it will print 14
然后它会打印 14
Hope this helps you
希望这对你有帮助
