Uploading To 2 Separate Sql Databases On Different Servers

Recommended Posts

Hi:  I am trying to figure out a way to send data to multiple SQL databases on two separate servers, and I did come across a couple of scripts that I have modified to my scripts, but I still can't get this to work with the mysql_connect.php.  Any ideas how to have multiple database connections on one script?  Thanks in advance.  Here are the scripts I'm using from Larry's book... 

---------------------------------------------------------------------------------------------------------

<?php # Script 12.8 - add_file.php
// This page allows users to upload files to the server.

// Set the page title and include the HTML header.
$page_title = 'Upload a File';
include ('./includes/header.html');
if(!isset($_SESSION['user_id'])){
        session_unset();
        session_destroy();
        header("Location:../login.php");
        exit;
        }

$counter = 1; // Number of files to allow for.

if (isset($_POST['submitted'])) { // Handle the form.

    require_once ('./mysql_connect.php'); // Connect to the database.

    
    for ($i = 0; $i < $counter; $i++) { // Handle each uploaded file.
    
        // Create index names to refer to the proper upload and candidate information.
                
        $firstname = 'firstname' . $i;
        $lastname = 'lastname' . $i;
        $email = 'email' . $i;
        $citizenship = 'citizenship' . $i;
        $location = 'location' . $i;
        $filename = 'upload' . $i;


    
        // Check for a file.
        
                    // Check for a first name (not required).
            if (!empty($_POST[$firstname])) {
                $f = "'" . escape_data($_POST[$firstname]) . "'";
            } else {
                $f = 'NULL';
            }

        
            // Check for a last name (not required).
            if (!empty($_POST[$lastname])) {
                $l = "'" . escape_data($_POST[$lastname]) . "'";
            } else {
                $l = 'NULL';
            }

            if (!empty($_POST[$email])) {
                $e = "'" . escape_data($_POST[$email]) . "'";
            } else {
                $e = 'NULL';
            }
            
                    // Check for a citizenship (not required).
            if (!empty($_POST[$citizenship])) {
                $c = "'" . escape_data($_POST[$citizenship]) . "'";
            } else {

            $result = mysql_query ($query);

                // Return the upload_id from the database.
                $upload_id = mysql_insert_id();

One of the simplest ways to do this is to initilize two database connection variables in your mysql.php script. When you perform queries on the second database, use the new variable instead.

<?php # mysqli.php

$dbc = mysli_connect( ... ); // You know the drill.

$other = mysqli_connect( ... ); // The details for the new connection

Inside your scripts, you can now use both $dbc and $other

require "mysql.php"; // Require connection script

$query = "SELECT * from someTable";
$result = mysqli_query($dbc, $query); // Using the "standard" connection

$query = "SELECT * from someOtherTable";
$result = mysqli_query($other, $query); // Using the "other" connection

Keep in mind that the mysql functions are deprecated. You should switch to mysqli. Most functions are almost identical, though.
