遷移兩段代碼，錯誤mysql_fetch_array（）期望參數1成爲資源

我已經遷移了一些代碼，一切正常，直到我在教程中遇到這段代碼。因爲我有一個自定義模板，所以html和php代碼與原始模板有點不同，現在我完全迷失了。遷移兩段代碼，錯誤mysql_fetch_array（）期望參數1成爲資源

這是原來的代碼，它應與一個此碼下方取代：

<table cellspacing="0" cellpadding="0" border="0" class="product"> 
    <tr> 
     <td width="103" height="104"><script language="javascript"><!-- 
document.write('<?php echo ' 
<a href="javascript:popupWindow(\\\'' . 
tep_href_link(FILENAME_POPUP_IMAGE, 'pID=' . 
$product_info['products_id']) . '\\\')">' 
. tep_image(DIR_WS_IMAGES . 
$product_info['products_image'], addslashes(
$product_info['products_name']), 
SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT, 'hspace="0" vspace="0"') . '</a>'; ?>'); 
//--></script> 
<noscript> 
<?php echo '<a href="' . tep_href_link(DIR_WS_IMAGES . 
$product_info['products_image']) . '" target="_blank">' . 
tep_image(DIR_WS_IMAGES . 
$product_info['products_image'], 
$product_info['products_name'], 
SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT, 'hspace="0" vspace="0"') . '</a>'; ?> 
</noscript></td> 
     <td width="344" height="104"><br> 
      <br style="line-height:5px"><?php echo stripslashes(
$product_info['products_description']); ?> 
<br style="line-height:1px;"><br style="line-height:5px;"> 
     </td> 
    </tr> 
    <tr> 
     <td width="447" height="1" colspan="2"> 
<img src="images/3_line.gif" alt="" border="0"><br></td> 
    </tr> 
    <tr> 
     <td height="38"> 
      <br style="line-height:12px"><script language="javascript"><!-- 
document.write('<?php echo ' 
<div style=" text-align:center; width:90%;"> 
<a href="javascript:popupWindow(\\\'' 
. tep_href_link(FILENAME_POPUP_IMAGE, 'pID=' . 
$product_info['products_id']) . '\\\')">' 
. TEXT_CLICK_TO_ENLARGE . '</a></div><br style="line-height:2px;">'; ?>'); 
//--></script> 
<noscript> 
<?php echo '<div style=" text-align:center; width:90%;"> 
<a href="' . tep_href_link(DIR_WS_IMAGES . 
$product_info['products_image']) . '" target="_blank"> 
<br style="line-height:7px">' . TEXT_CLICK_TO_ENLARGE . '</a> 
</div> 
<br style="line-height:2px;">'; ?> 
</noscript> 

     </td> 
     <td style=" vertical-align:middle; padding-left:20px;"><strong> 
<?=$products_price?></strong><br></td> 
    </tr> 
</table>

這是我與原來的（一個以上此代碼）來替換代碼：

這是它產生在我的網站錯誤：

Warning: mysql_fetch_array() expects parameter 1 to be resource, null given in.. 
includes/functions/database.php on line 99

這是行99

function tep_db_fetch_array($db_query) { 
    return mysql_fetch_array($db_query, MYSQL_ASSOC); 
    }

任何幫助將是巨大的，原諒我的代碼的格式，我試圖使它儘可能好的，但有些回聲線是長。

你能告訴我們圍繞99行的代碼嗎？我的意思是在該行之前有更多行。 '$ db_query'是如何設置的。 – codaddict 2010-10-13 14:35:08

感謝您的回覆，我編輯了我的問題。 fyi，圖像效果（fancybox）正在運行，它不會做的事情就是從數據庫中提取有關產品的信息 – Chris 2010-10-13 14:44:57

「tep_db_fetch_array」在哪裏被調用？ – codaddict 2010-10-13 14:56:51

由於錯誤信息，你傳遞到tep_db_fetch_array()的$ db_query顯然是不正確設置。某處它被取消，被覆蓋，被稱爲超出範圍，或者你在某個參數中有一個錯字。

它被嚴重覆蓋。謝謝大家 – Chris 2010-10-13 17:41:18
