我在我的销售点模块上添加了一个删除按钮。在我点击删除时在购买标签中，它不会从数据库中删除我的条目。每当我点击删除按钮时，我需要帮助从数据库中删除购买条目。< / p>

答案 0 :(得分：0)
感谢所有人的注意力。我已经按照以下方式完成了这项工作
if ($tablename == "stock_entries") {
$difference = $db->queryUniqueValue("SELECT quantity FROM stock_entries WHERE id=$id");
$sid = $db->queryUniqueValue("SELECT stock_id FROM stock_entries WHERE id=$id");
$id = $db->queryUniqueValue("SELECT id FROM stock_entries WHERE salesid='$sid'");
$name = $db->queryUniqueValue("SELECT stock_name FROM stock_entries WHERE id=$id");
$result = $db->query("SELECT * FROM stock_entries where id > $id");
while ($line2 = $db->fetchNextObject($result)) {
$osd = $line2->opening_stock - $difference;
$csd = $line2->closing_stock - $difference;
$cid = $line2->id;
$db->execute("UPDATE stock_entries SET opening_stock=" . $osd . ",closing_stock=" . $csd . " WHERE id=$cid");
}
//echo "purchase $name";
$total = $db->queryUniqueValue("SELECT quantity FROM stock_avail WHERE name='$name'");
$total = $total - $difference;
$db->execute("UPDATE stock_avail SET quantity=$total WHERE name='$name'");
$db->execute("DELETE FROM $tablename WHERE id=$id");
$db->execute("DELETE FROM $tablename WHERE id=$id");
}
