如何訪問視圖中的Laravel類？

Question

如果我在控制器，這條線會做到這一點。

use App\UBBUserSetting, App\UBBSetting;

---

但我在視圖中

我想包括在我看來，我的課（.blade.php）

我不能

use App\UBBUserSetting, App\UBBSetting; 


    $ubb_user_settings = UBBUserSetting::where('cpe_mac','=',$cpe_mac)->get(); 
    $ubb_settings = UBBSetting::where('cpe_mac','=',$cpe_mac)->first(); 
    if($ubb_settings != null){ 
     $jump_bandwidth = $ubb_settings->jump_bandwidth; 
     $paid = $ubb_settings->price_per_jump; 
    } 

    $option2 = 0; 

    if($ubb_user_settings != null){ 
     $option1_selected = []; 
     $option2_selected = []; 

     $lines = count($ubb_user_settings); 

     foreach ($ubb_user_settings as $i => $ubb_user_setting) { 
      if($ubb_user_setting->option == 1){ 
       $option1_selected[$i]['d'] = $ubb_user_setting->created_at->format('d'); 
       $option1_selected[$i]['threshold'] = (int)$ubb_user_setting->volume_current_limit; 

      }else{ 

       $option2++; 
       $option2_selected[$i]['d'] = $ubb_user_setting->created_at->format('d'); 
       $option2_selected[$i]['threshold'] = (int)$ubb_user_setting->volume_current_limit; 
       $option2_selected[$i]['next_threshold'] = $threshold + ($jump_bandwidth * $option2); 

      } 
     } 

    }

一個如何去和這樣做？

任何提示？

Answer 1

如果你想使用刀片意見任何PHP代碼，使用<?php ?>標籤，你可以使用完整的命名空間：

<?php 
    .... 
    $ubb_user_settings = \App\UBBUserSetting::where('cpe_mac','=',$cpe_mac)->get(); 
    .... 
?> 

但它是一個可怕的做法，從視圖運行查詢。你應該真的學習MVC模式。

Answer 2

這應該是你的代碼：

$ubb_user_settings = \App\UBBUserSetting::where('cpe_mac','=',$cpe_mac)->get(); 
$ubb_settings = \App\UBBSetting::where('cpe_mac','=',$cpe_mac)->first(); 
if($ubb_settings != null){ 
    $jump_bandwidth = $ubb_settings->jump_bandwidth; 
    $paid = $ubb_settings->price_per_jump; 
} 

$option2 = 0; 

if($ubb_user_settings != null){ 
    $option1_selected = []; 
    $option2_selected = []; 

    $lines = count($ubb_user_settings); 

    foreach ($ubb_user_settings as $i => $ubb_user_setting) { 
     if($ubb_user_setting->option == 1){ 
      $option1_selected[$i]['d'] = $ubb_user_setting->created_at->format('d'); 
      $option1_selected[$i]['threshold'] = (int)$ubb_user_setting->volume_current_limit; 

     }else{ 

      $option2++; 
      $option2_selected[$i]['d'] = $ubb_user_setting->created_at->format('d'); 
      $option2_selected[$i]['threshold'] = (int)$ubb_user_setting->volume_current_limit; 
      $option2_selected[$i]['next_threshold'] = $threshold + ($jump_bandwidth * $option2); 

     } 
    } 

} 

您可以設置命名空間中的類之前，所以這將是App\UBBUserSetting的::where()之前。由於您處於刀片視圖中，而不是類中，因此應該在類之前使用名稱空間。

希望這個作品！

做獨立：

use App\UBBUserSetting; 
use App\UBBSetting;
