Subject: Self-calling script problem.
I have a script that asks a user to login using an ID and
password, it then
displays a login menu based on the users access type.
This script works on another machine, but I have attempted to
set up PHP on
two new machines and keep getting the same problem.
The script runs but when the user types in their data and clicks the
continue button the parameters being input into the script do
change but it
looks like it is being ignored.
e.g
Calling the page for the first time works:
http://160.221.21.129/timelog/index.php
Self-calling with the additional user_id
parameter set results
in the login screen being shown again!
http://160.221.21.129/timelog/?user_id=99999
This should now show the users menu options. (As on the other system!)
If I don't put in a user Id and password the screen is
updated to reflect
this, I don't understand this as again this is calling itself
to perform
this change.
My script is included below, any help would be much appreciated:
<?php
// (Re-)Start the session handler
session_start();
include ( $to_root.'scripts_php/common.php' );
if ( isset ($_GET['LOGOUT']) ) {
$_SESSION = array();
header ('Location: http://'.$thiswebsite);
}
// Get the task_id, if supplied
$task_id = trim ($_REQUEST['task_id']);
$errormsg = '';
// Login requested?
if ( $_POST['login'] == 'Click To Login' ) {
$username = trim ($_POST['username']);
$f_username = fixquotes ($username); // fixed for
SQL statements
$passwd = trim ($_POST['passwd']);
// $f_passwd = fixquotes (md5 ($passwd)); // fixed for SQL
statements
$f_passwd = fixquotes ($passwd); // fixed for SQL
statements
// Error check the form data
if ( strlen ($username) == 0 ) {
$errormsg .= 'You must supply a
username in the form
<em>Lastname Firstname</em>.<br />';
}
if ( strlen ($passwd) == 0 ) {
$errormsg .= 'You must supply a
password.<br />';
}
$allok = ( strlen ($errormsg) > 0 ) ? false : true;

";

accessing the database.<br />';
}
elseif ( mysql_num_rows ($rs) != 1 ) {

and/or password
