不显示错误页面

Question

我想弄清楚为什么当一个userID和/或registrationKey没有放入URL中时，它不显示404错误页面。应该发生什么情况是激活控制器被加载时，它应该查看userID和registrationKey是否在URL中，如果不是，则转到错误页面。

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class Activate extends CI_Controller { 

public function __construct() 
{ 
    parent::__construct(); 
    $this->load->model('users/usersmodel'); 
} 

public function index($userID = NULL, $registrationKey = NULL) 
{ 
    //Config Defaults Start 
    $msgBoxMsgs = array();//msgType = dl, info, warn, note, msg 
    $cssPageAddons = '';//If you have extra CSS for this view append it here 
    $jsPageAddons = '';//If you have extra JS for this view append it here 
    $metaAddons = '';//Sometimes there is a need for additional Meta Data such in the case of Facebook addon's 
    $siteTitle = '';//alter only if you need something other than the default for this view. 
    //Config Defaults Start 


    //examples of how to use the message box system (css not included). 
    //$msgBoxMsgs[] = array('msgType' => 'dl', 'theMsg' => 'This is a Blank Message Box...');

    if(!is_numeric($userID) || !preg_match('/^[A-Za-z0-9]+$/', $registrationKey)) 
    { 
     show_404(); 
    } 
    else 
    { 
     $registrationDetails = $this->usersmodel->getRegistrationDetails($userID); 
     if (!is_null($registrationDetails)) 
     { 
      $regKeyDate = $registrationDetails->registrationKeyDate; 

      if ($this->usersmodel->activateUser($userID, $registrationKey)) 
      { 
       $message = 'User was activated successfully! You may now login!';     
      } 
      else

       $message = 'User was not activated successfully! Please try again with the right credentials!';

    //If msgBoxMsgs array has anything in it, if so displays it in view, else does nothing.  
    if(count($msgBoxMsgs) !== 0) 
    { 
     $msgBoxes = $this->msgboxes->buildMsgBoxesOutput(array('display' => 'show', 'msgs' =>$msgBoxMsgs)); 
    } 
    else 
    {

    } 

    if($siteTitle == '') 
    { 
     $siteTitle = $this->metatags->SiteTitle(); //reads 
    } 

    //Double checks if any default variables have been changed, End.

} 

}

任何想法？

我认为代码看起来很好，但是您可能需要对自己的问题进行一些解决。如果你不通过你的URI传递参数，并且show_404（）函数没有被调用，那么你需要看看这些变量包含什么。由于userID不是数字或registrationKey不仅仅是字母数字。如果你在他们之前var_dump声明，并且不通过你的URI参数，会发生什么？
