passing data from controller to blade view laravel
提问by Ileana Profeanu
I am trying to send parameters through a href to a page from an events list to an event page.
我正在尝试通过 href 将参数发送到从事件列表到事件页面的页面。
My route is
我的路线是
Route::get('eventpage', 'EventController@index')->name('eventpage');
And my event Controller is
我的事件控制器是
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class EventController extends Controller
{
public function index(Request $request)
{
$id = $request->query('id');
$event = DB::table('events')->where('id',$id)->get();
$pics = DB::table('pictures')->where('event_id',$id)->get();
$n = count($pics); // the number of pictures for a particular event
return view('pages.eventPage');
}
}
}
The trouble is that for the first variable I try to use, $n, it gives me an error, "Undefined variable: n "
麻烦的是，对于我尝试使用的第一个变量 $n，它给了我一个错误，“未定义的变量：n”
My blade code is as follows
我的刀片代码如下
@for($i = 1; $i < $n; $i++)
<li data-target="#carousel-example-generic" data-slide-to="{{ $i }}"></li>
@endfor
What am I doing wrong?
我究竟做错了什么？

You can pass your data to your view like that:
您可以像这样将数据传递给您的视图：
public function index(Request $request)
{
....
return view('pages.eventPage', compact('id', 'event', 'n'));
}
