ช่วยด้วยค่ะ insert max id +1 id เป็น 1 ตลอดค่ะ ช่วยดูโค๊ดให้ทีนะค่ะ

$q1 = "SELECT MAX(q_item) as maxq FROM question WHERE q_department = $em_dep";
			$res = mysql_query($q1);
			$row = mysql_fetch_array($res);
			
			$max_id = $row['maxq'];
			
			$max_id_plus = $max_id + 1;

			 $strSQL = "INSERT INTO question(em_id,q_department,q_category,q_quest,q_ans,q_status,q_item) ";
			 $strSQL .="VALUES ('$em_id','$em_dep','2','".$_POST['q_quest'.$i]."','".$_POST['q_ans'.$i]."','1',$max_id_plus) ";
			 $objQuery = mysql_query($strSQL,$conn) or die(mysql_error());
			
			

$total_mark=0;
foreach($_POST['choice'] as $key=>$value){

$sql1 = " select * from question where q_item = $key and q_ans = '$value' ";
$rs1 = mysql_query($sql1) or die(mysql_error());

$total_mark += mysql_num_rows($rs1); 

$total_mark=0;

echo $sql,"<br />\n";
$rs1 = mysql_query($sql1) or die(mysql_error());

$total_mark += mysql_num_rows($rs1); // เกิดเจอมากกว่า 1 เรคคอร์ดทำจะยังไงครับ มันต้องบวกมากกว่า 1 แน่ๆ
// ใช้ ++$total_mark; ดีกว่า
