my mysql.php page:

<?php
$dbhandle = mysql_connect("localhost", "root", "", "client");

if (!$dbhandle) {
    die("Connection failed: " . mysql_connect_error());

Answer 1

Use mysql_select_db :

$dbhandle = mysql_connect("localhost", "root", "");

if (!$dbhandle) {
    die("Connection failed: " . mysql_connect_error());
}
mysql_select_db('my_database_name', $dbhandle);
....

The best option here change to mysqli_* functions , and create a specific user for your table, with some grants:

$dbhandle = mysqli_connect("localhost", "client_db_user", "client_db_password", "client");
...

After you get connected to the database, change your mysql_query into variable to make it easier to identify.

$query = mysql_query("your query");

 if ($query) { echo "Insertion success"; } else { echo "Failed"; echo mysql_error(); }; 

And also add var_dump($_POST); to identify which variable did you send from the previous file.
