上传2张图片并从数据库中检索第一个ID

Question

I uploaded 2 images into the database and want to retrieve from the database by id... I dont know how to retrieve for the first ID. I can retrieve the second ID using :

$lastid = mysql_insert_id();


//declare where the image is from
$before = $row['image']; //want to retrieve first id
$after = $row['image']; //this can be get by the $lastid

///updated my codes

I declared like this :

  $lastid = mysql_insert_id();
    $pic = mysql_query("SELECT * FROM images WHERE id='$lastid'");
    $row = mysql_fetch_assoc($pic);

    //declare where the image is from
    $before = $row['image'];
    $after = $row['image'];

when I output the image, i got 2 last id
