非常感谢有人帮助解决问题。顺便说一句，我在 Magento 我有这种方法，它基本上需要两组数据并用它们创建一个 sql 语句。

private function _getInsertSql($data, $itemData)
{

    $sql = 'insert into orders_headers (';
    $keys = array_keys($data);
    $sql .= implode(', ', $keys);
    $sql .= ') values (';
    foreach($data as $value) {
        $type = $value['type'];
        $vv = $value['value']; 
        if ($type == 'number') {
            $sql .= $vv;
        } else {
            $sql .= $this->_db->quote($vv);
        }
        $sql .= ',';
    }
    $sql = substr($sql, 0, strlen($sql)-1);
    $sql .= ');';

    $first = 0;
    $sql .= 'insert into orders_lines (';
    foreach($itemData as $data) {
        if ($first <= 0) {
            $keys = array_keys($data);
            $sql .= implode(', ', $keys);
            $sql .= ') values (';
        } else {
            $sql .= '('; 
        }
        foreach($data as $value) {
            $type = $value['type'];
            $vv = $value['value']; 
            if ($type == 'number') {
                $sql .= $vv;
            } else {
                $sql .= $this->_db->quote($vv);
            }
            $sql .= ',';
        }
        $sql = substr($sql, 0, strlen($sql)-1);
        $sql .= '),';
        $first++;
    }

    $sql = substr($sql, 0, strlen($sql)-1);

    $sql .= ';';
    Mage::log("START" .$sql . "END", NULL, 'sql.log');
    return $sql;
}

正如您在最后看到的那样，我正在注销 .sql，但奇怪的是它两次生成了相同的查询。因此在数据库中插入同一行两次。

我一辈子都看不到它循环到顶部并再次创建查询的位置。

输出的sql是：

有人可以提供帮助吗？

谢谢

【问题讨论】：

你能发布 $sql 的最终值是多少吗？
我已将其添加到最初的问题中

【解决方案1】：

我认为 foreach 并没有给你两次查询，而是你的方法被调用了两次。代码中的 log 方法位于 foreach 循环之外，并且日志文件本身包含 2 个条目（包含在 START 和 END 中）。最好找出你在哪里调用该方法并在那里调试。

【解决方案2】：

经过一番挖掘，我发现 afterordersaved 事件被调用了两次。

我相信是由 customer_save_observer_executed 为了解决这个问题，我刚刚完成了以下操作：-

if(Mage::register('customer_save_observer_executed')) {
return;
}
Mage::log('afterOrderSavedObserver call', NULL, 'method_calls.log');                
$model = Mage::getModel('ordersintegration/export');
$model->afterOrderSavedXm1($order);
Mage::register('customer_save_observer_executed', true);

现在可以了
