$order_details="INSERT INTO .....";
mysql_query($order_details);
$o_id_detail[]=mysql_insert_id();
}

$prev_id=implode(',',$o_id_detail);
$last_id=explode(',',$prev_id);
foreach($last_id as $last)
{
    $last;
    foreach($addon_price as $a_p=>$p)
    { 
        echo $a_p;
        foreach($p as $m)
        {

            $addon_id= $m['id'];
            echo $m['addon_name'];
            echo $m['deposit'];
            echo $m['ppd'];
            echo $m['pp_eight'];
            echo $m['pp_six'];

            $addon_total = $m['deposit']+$m['ppd']+$m['pp_eight']+$m['pp_six'];
            echo $addon_total;

            $addon_detail="INSERT INTO tbl_orderdetail_addon 
                                (OrderID,addOns_id,addOns_price) 
                            VALUES ('$last','$addon_id','$addon_total')";
            if(!empty($addon_id)){
                mysql_query($addon_detail)or die(mysql_error());
            }
        }     
   }   
}
}

现在，我得到（$ last）多次插入foreach循环（foreach（$ addon_price as $ a_p =＆gt; $ p））。如果特定addon_item的（$ last）id已经存在，如何限制（$ last）id表单再次插入任何行？

编辑部分：

$o_id_detail=mysql_insert_id();

    foreach($addon_price as $a_p=>$p)
               { 
                echo $a_p;
                   foreach($p as $m)
                   {

                       $addon_id= $m['id'];
                       echo $m['addon_name'];
                       echo $m['deposit'];
                       echo $m['ppd'];
                       echo $m['pp_eight'];
                       echo $m['pp_six'];
                  $addon_total=$m['deposit']+$m['ppd']+$m['pp_eight']+$m['pp_six'];
                   echo $addon_total;




$addon_detail="INSERT INTO tbl_orderdetail_addon (OrderID,addOns_id,addOns_price) VALUES ('$o_id_detail','$addon_id','$addon_total')";
if(!empty($addon_id))
                {
                mysql_query($addon_detail)or die(mysql_error());


              }
            }     
         }   
}

Answer 1

在(OrderID, addOns_id)上向表格添加唯一的综合索引。然后使用

$addon_detail="INSERT IGNORE INTO tbl_orderdetail_addon 
                    (OrderID,addOns_id,addOns_price) 
                VALUES ('$last','$addon_id','$addon_total')";

IGNORE选项意味着如果有重复的密钥，它将默默跳过插入尝试。

为所有记录插入相同的id，并重复与foreach循环一样多次
