我有来自OSCommerce的代码段，如
while ( $product_array = tep_db_fetch_array($this->products_sql)) {
// do some stuff
}
除了要求提供更多信息之外，有关代码之前的完整功能如下所示。
function get_next_product() {
global $Count, $shoppingCart;
if ($Count && ($this->Products >= $Count)) {
return NULL;
}
$product = NULL;
while ($product_array = tep_db_fetch_array($this->products_sql)) {
$GLOBALS['exporter_module']->checkUsedMemory();
$GLOBALS['shoppingCart']->processProductData($product_array);
foreach ($this->values as $valueName => $valuesArr) {
$product_array[$valueName] = $valuesArr[$product_array['products_id']];
}
$product = $product_array;
$product_array['id'] = $product_array['products_id'];
$product['id'] = $product_array['products_id'];
$product['quantity'] = $product_array['products_quantity'];
// get special price
$special_price = $this->getSpecial($product_array);
if (null !== $special_price['price']) {
$product['price'] = $special_price['price'];
$_product['is_special'] = 1;
} else {
$product['price'] = $product_array['products_price'];
$product['is_special'] = 0;
// Include in Base Price, When Priced by Attributes.
if (isset($product['products_priced_by_attribute'])
&& $product['products_priced_by_attribute'] == 1
&& $product['products_price'] == 0
&& $product['products_price_sorter'] != 0) {
$product['price'] = $product['products_price_sorter'];
$product_array['products_price'] = $product['products_price_sorter'];
}
}
}
根据找到的信息on the zen cart wiki我将Zen Cart改为
while (!$product_array->EOF) {
// do some stuff
$product_array->MoveNext();
}
现在得到致命错误：在数组上调用成员函数MoveNext（） $ this-＆gt; products_sql是在同一文件中其他位置找到的函数的内容。然而，即使这不是真正的SQL查询。
function get_products()
{
$this->products_sql = $this->select_products($this->options['categories'], $this->options['language'], $this->options['quantities'], $this->options['withzero'], $this->options['stockout'], $this->options['sub']);
}
我认为如果你知道原始代码中包含的$ this-＆gt; products_sql是多少就会有所帮助，所以var_dump如下所示。

答案 0 :(得分：0)
我假设$this->products_sql是一个真正的SELECT字符串，对吗？ （如果没有，请发布更多上下文。）假设如此，您的代码应为：
$this->products_sql = "SELECT bla bla bla";
$product_array = $db->Execute($this->products_sql);
while (!$product_array->EOF) {
// do some stuff
// product_array fields are $product_array->fields['field1'], etc.
$product_array->MoveNext();
}
