Using Postgres and PHP3 Authentication from a Web application
Login to remove this ad.
//
// This little PHP script shows you how to connect to a Postgres
// database via a browser with User/Password database
// authentication using PHP3 authenticate function.
//
// 1) You have to modify the $PGDATA/pg_hba.conf file:
// local all trust
// -> trusting all connection for everyone on local machine
// host all 127.0.0.1 255.255.255.255 password passwd
// -> using password like file (passwd made using pg_passwd tool
// to create user password account) to authenticate users
// from everywhere
// 2) Just use the pg_Connect (or pg_pConnect) function with the
// connection string as follows.
//
<?PHP
//
// Authentication function - see previous archives for comments
//
function authenticate() {
Header("WWW-authenticate: basic realm=\"Intranet MBDS\"");
Header("HTTP/1.0 401 Unauthorized");
$title="Login invalide";
?>
In order to proceed you will need a valid username/password.
<?
exit;
}
//
// Postgres Connection
//
function connect($user,$passwd) {
// You simply have to change the following variables to match
// your site configuration
// HOSTNAME = name of your postgres base host
// DBNAME = name of your postgres base
$conn = pg_Connect("host=HOSTNAME dbname=DBNAME port=5432
user=$user password=$passwd");
// Db connection problem
if (!$conn) {
echo "Database connection error.\n";
exit;
}
// SQL order
$query_parent="SELECT * FROM xxxx WHERE xxxx";
$result = pg_Exec($conn,$query_parent);
if (!$result) {
echo "SQL order problem.\n";
exit;
}
// ...
// End of SQL statment
pg_FreeResult($result);
pg_Close($conn);
}
//
// Main part of your PHP script
//
if (!isset($PHP_AUTH_USER)) {
authenticate();
}
else {
connect($PHP_AUTH_USER,$PHP_AUTH_PW);
}
?>
