我的SQL函數返回未定義的函數錯誤

Question

我試圖顯示基於以下條件廣告打電話：

• 主動廣告= 6，運行showActiveAdvert()功能
• 主動廣告= 6，運行getActDefault()功能
• 主動廣告= 0，運行getDefaultBanner()功能

現在的問題是，當我運行這個功能事情是這樣的，它返回Fatal error: Call to undefined function getDefaultBanner() in /home1/xxxxxxx/public_html/skin/widgets/myAdServer.php on line 47。我試圖嵌套最後一個功能getDefaultBanner()，但它不顯示任何內容。

我該如何糾正？

這裏的功能是：

function showActiveAdverts() { 
    $status = 1; 
    //Build final queries. 
    $query = mysql_query("SELECT * FROM fpf_adverts WHERE 
     status = '".mysql_real_escape_string($status)."' 
     ORDER BY rand() LIMIT 6 ") or die(mysql_error()); 

     $count = mysql_num_rows($query); $row = mysql_fetch_assoc($query); 

     if ($count >= 1) { 
      do { 
       $list[] = $row['id']; 
      } while ($row = mysql_fetch_assoc($query)); 
      return $list; 
     } else { 
      return FALSE; 
     } 
    } 

    function getActDefault() { 
     $status1 = 1; 
     $status2 = 6; 
     //Query DB for both active and default adverts 
     $query = mysql_query("(SELECT * FROM fpf_adverts WHERE status = '".mysql_real_escape_string($status1). 
      "' ORDER BY rand()) UNION ALL (SELECT e.*FROM fpf_adverts e JOIN fpf_adverts ee ON e.status + 6 > ee.status WHERE e.status = '".mysql_real_escape_string($status2). 
      "') LIMIT 6 ") or die(mysql_error()); 

     $count = mysql_num_rows($query); 
     $row = mysql_fetch_assoc($query); 

     if ($count >= 1) { 
      do { 
       $list[] = $row['id']; 
      } while ($row = mysql_fetch_assoc($query)); 
      return $list; 
     } else { 
      return FALSE; 
     } 
    } 

    function getDefaultBannner() { 
     $status = 6; 
     $query = mysql_query("SELECT e.* FROM fpf_adverts e JOIN fpf_adverts ee ON e.id + 6 > ee.id WHERE e.status = 
      '".mysql_real_escape_string($status)."' 
      LIMIT 6 ") or die(mysql_error()); 

      $count = mysql_num_rows($query); $row = mysql_fetch_assoc($query); 

      if ($count >= 1) { 
       do { 
        $list[] = $row['id']; 
       } while ($row = mysql_fetch_assoc($query)); 
       return $list; 
      } else { 
       return FALSE; 
      } 
     } 

，這裏是我使用的遍歷，以便它可以在前臺顯示的功能：

<?php 
$showBoard_arr = showActiveAdverts(); 
//Defining this before the first function, in case no results. 
$countBoard = 0; 
$advertTop .= '<div class="adSlot">'; 
$advertBottom .= '<div class="adSlot">'; 

if ($showBoard_arr) { 
    foreach ($showBoard_arr as $key => $showBoard) { //Get information from my DB 
     $countBoard += 1; 
     $advertId  = getAdLocation($showBoard, 'id'); 
     $advertTitle = getAdLocation($showBoard, 'title'); 
     $advertImg  = refineProfileImage(getAdLocation($showBoard, 'img_url')); 
     $advertUrl  = $site_path . "clicks/" . $board_slug . "/" . $advertId;

     $countBoard = 0; 
     $advertTop  = '<div class="adSlot">'; 
     $advertBottom = '<div class="adSlot">'; //Empty the first function adverts. 
     $showBoard_arr = getActDefault(); //Get the adverts from this function.

      $countBoard += 1;

      } 
     } 
    } 
} 
//So if we are here there are 2 options: 1) First or second function done. 
//2) No results so we need the third function to be called. 
if ($countBoard == 0) { //If there are no results at all. 
    $showBoard_arr = getDefaultBanner(); //Get adverts from this other function. 
    //Repeating foreach statement. 
    foreach ($showBoard_arr as $key => $showBoard) { //Get information from my DB 
     $countBoard += 1; 
     $advertId  = getAdLocation($showBoard, 'id');

     } 
    } 
} 

//Now we are done, for x, y or z, the adverts are loaded. So we show them. 
$advertTop .= '</div>'; 
$advertBottom .= '</div>'; 

echo $advertTop;
