I am new to PHP. I am working on a form which has a table with thee columns that is two textboxes and and one combo box. I used JavaScript for generating the table rows and the same to delete it. I also referred one of your blogs for generating the rows. Now I am stuck on how to save the values from the the generated textbox to the MySQL database. Can anyone help me out? It would be a huge favor.

Here is my code:

<?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());
            }
    }
?>

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。

请参阅此示例。

<?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。
