我是PHP的新手。我正在处理一个表格，其中包含一个表格，其中包含两个文本框和一个组合框。我使用JavaScript生成表行，同样删除它。 我还引用了一个博客来生成行。现在我被困在如何将生成的文本框中的值保存到MySQL数据库中。谁能帮我吗？这将是一个巨大的帮助。
这是我的代码：
<?php
session_start();
if (!isset($_SESSION["username"])) {
header("Location: unauthorize_access.php");
}
if(isset($_POST['submit']))
{
$length = count($_POST['testparameters']);
for($i=0; $i< $length; $i++){
$TestParameters=$_POST['testparameters'][$i];
if(!empty($TestParameters)){
$InsertQuery = "INSERT INTO color(name) VALUES('$TestParameters')";
$result=mysql_query($InsertQuery) or die(mysql_error());
}
}
if(!$InsertQuery)
{
die('Could not enter data:' . mysql_error());
}
}
?>

答案 0 :(得分：-1)
如果我错了，请纠正我。 我没有看到任何打开mysql数据库连接的代码。
见这个例子。
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
// Create database
if (mysql_query("CREATE DATABASE my_db",$con))
{
echo "Database created";
} else {
echo "Error creating database: " . mysql_error();
}
?>
在使用 mysql_query 插入记录之前，请确保您打开了如上所述的mysql数据库连接。
