【问题描述】：
我需要将动态文本框值插入到同一 id 的数据库表中，现在我可以只在不同的用户 id 上插入值。
当我尝试将动态文本框值插入 id 1 上的数据库表中时，动态文本框值将变为不同的 id，如 2、3、4 等。并且也成为 id 1 的零字段值。@ 987654321@
这是我的 html 和 javascript 代码：
文件名：index.php
<!DOCTYPE html>

这是我插入数据库的 php 代码
<?php
$username="root";
$password="sha12345";
$hostname="localhost";
$dbhandle = mysql_connect($hostname,$username,$password) or die("Could not connect to database");
$select = mysql_select_db("sha", $dbhandle);
if(isset($_POST['save']))
{
$personname = $_POST['first_name1'];
$fathername = $_POST['first_name2'];
$mothernname = $_POST['first_name3'];
mysql_query("INSERT INTO sha(Name_person,Name_father,Name_mother) VALUES ('$personname','$fathername','$mothernname')");
if(!empty($_POST["save"])) {
$itemCount = count($_POST["name1"]);
$itemValues=0;
$query = "INSERT INTO sha (no_members,name_members,age_members,relation_members,occupation_members) VALUES ";
$queryValue = "";
for($i=0;$i<$itemCount;$i++) {
if(!empty($_POST["name1"][$i]) || !empty($_POST["name2"][$i]) || !empty($_POST["name3"][$i]) || !empty($_POST["name4"][$i]) || !empty($_POST["name5"][$i])) {
$itemValues++;
if($queryValue!="") {
$queryValue .= ",";
}
$queryValue .= "('" . $_POST["name1"][$i] . "', '" . $_POST["name2"][$i] . "', '" . $_POST["name3"][$i] . "', '" . $_POST["name4"][$i] . "', '" . $_POST["name5"][$i] . "')";
}
}
$sql = $query.$queryValue;
if($itemValues!=0) {
$result = mysql_query($sql);
if(!empty($result)) $message = "Added Successfully.";
}
}
}
mysql_close();
?>
