致命错误：在第 105 行调用 /webshop/index.php 中未定义的函数 tep_db_fetch_assoc()

Question

有人给我写了一段代码，但是在实现该代码片段后，出现了标题中的错误。

这是片段：

似乎tep_db_fetch_assoc() 被定义为$row，这是真的吗？为什么我会收到此错误？

// Start auto fetch category image from product
if($categories['categories_image'] == "") {
$categories_img_query = tep_db_query("select products_image from " . TABLE_PRODUCTS . " p, products_to_categories pc WHERE p.products_id = pc.products_id AND pc.categories_id = '{$categories['categories_id']}' AND p.products_image IS NOT NULL order by p.products_id ASC");

while ($row = tep_db_fetch_assoc($categories_img_query)) { 
  if ($row['products_image'] <> 'noimage.jpg' 
     or !isset($categories['categories_image']) 
  ) { 
     $categories['categories_image'] = $row['products_image']; 
  } 
} 
else {
 $categories_img_parent_query = tep_db_query("select categories_id from categories WHERE parent_id = '{$categories['categories_id']}'");

 while($categories_img_parent = tep_db_fetch_array($categories_img_parent_query)) {
   $categories_img_query = tep_db_query("select products_image from " . TABLE_PRODUCTS . " p, products_to_categories pc WHERE p.products_id = pc.products_id AND pc.categories_id = '{$categories_img_parent['categories_id']}' AND p.products_image IS NOT NULL order by p.products_id ASC");
   while ($row = tep_db_fetch_assoc($categories_img_query)) { 
  if ($row['products_image'] <> 'noimage.jpg' 
     or !isset($categories['categories_image']) 
  ) { 
     $categories['categories_image'] = $row['products_image']; 
  } 
} 
 }
}
}
// End auto fetch category image from product

Answer 1

tep_db_fetch_assoc 不存在。您可能缺少定义该函数的文件，或者函数名称不正确。尝试使用 tep_db_fetch_array 来查看它是否返回一个像 tep_db_fetch_assoc 应该返回的关联数组。

Answer 2

我不认为tep_db_fetch_assoc是php的函数，它是一个自定义函数。 确保您包含包含该函数的库/类/文件。
