Question

我有一个控制器（PromoCode_Controller），它是Page_Controller的扩展。当我触发动作时，我希望页面重定向回到它来自的页面。我目前已设置$this->redirectBack()，但它没有开始......

我在'config.yml'文件中定义了Page_Controller：

Page_Controller:
  extensions:
    - PromoCode_Controller

控制器看起来像这样：

<?php

class PromoCode_Controller extends Extension {
    private static $allowed_actions = array(
        'DisplayCodes',
        'DeleteCode'
    );

    public function DisplayCodes() {
        //Display users promo codes
        $arrayList = ArrayList::create();
        $codes = PromoCode::get()->filter(array(
            "OwnerID" => Member::currentUserID(),
        ));

        foreach($codes as $code) {
            $arrayList->push($code);
        }
        return $arrayList;

    }

    public function DeleteCode() {
        $codeID = $this->owner->request->param("ID");
        //if($codeID && $code = PromoCode::get()->byID($codeID)) {
        //  $code->delete();
        //}
        echo $codeID;
        $this->redirectBack();
        return $this;
    }

}

我的模板中有一个链接，用于删除数据库中的代码。当我单击该链接时，它会在空白页面上打印$ codeID变量，但它不会触发重定向。

有人可以帮助指出我出错的地方吗？

所以我偶然偶然发现了这个问题。这是完整的代码：

- (NSString*)defaultRouter {

    SCDynamicStoreRef ds = SCDynamicStoreCreate(kCFAllocatorDefault, CFSTR("myApplication"), NULL, NULL);
    CFDictionaryRef dr6 = SCDynamicStoreCopyValue(ds, CFSTR("State:/Network/Global/IPv6"));
    CFDictionaryRef dr4 = SCDynamicStoreCopyValue(ds, CFSTR("State:/Network/Global/IPv4"));
    if(dr6)
      {
        CFStringRef router = CFDictionaryGetValue(dr6, CFSTR("PrimaryInterface"));
        NSString *routerString = [NSString stringWithString:(__bridge NSString *)router];
        self.primaryInterface=routerString;
           return self.primaryInterface;
                CFRelease(dr6);

      }
    else if(dr4)
      {

        CFStringRef router = CFDictionaryGetValue(dr4, CFSTR("PrimaryInterface"));
        NSString *routerString = [NSString stringWithString:(__bridge NSString *)router];
        NSLog(@"%@", routerString);
        self.primaryInterface=routerString;
           return self.primaryInterface;
                CFRelease(dr4);
      }
    CFRelease(ds);
    return 0;

  }
