Different user different content

[sheenandola]

Hello. Is it possible to use java script to direct users to different page depending on their username login and password? And if so, what is the script?

The website i am creating is for a conference my school is hosting. What I want to do is give the username and password for each delegation to use; once they log in, they will be directed to a page which contains information pertaining only to their delegation.

Right now, this is the script I have, but it only directs to one page, which is "user1.php". I want to be able to direct user2 to user2.php, user3 to user3.php and so on.

<?php
$usernames = array("user1", "user2", "user3", "superman");
$passwords = array("pass1", "pass2", "password3", "supermans password");
$page = "user1.php"

for($i=0;$i<count($usernames);$i++){
$logindata[$usernames[$i]]=$passwords[$i];
}
if($logindata[$_POST["username"]]==$_POST["password"]){
session_start();
$_SESSION["username"]=$_POST["username"];
header('Location: '.$page);
exit;
}else{
header('Location: login.php?wrong=1');
exit;
}
?>

Any help would be greatly appreciated. Thanks!

Maybe

header('Location: '.$page);

becomes

header('Location: '.$_POST["username"].'php');

Welcome to the forum.

ps This seems more like PHP than JavaScript !

I agree, Javascript is not what's needed here. I'd approach this a little differently; it's not a "different page" per se, it's different content based on the user. Also this page can be bookmarked, emailed, it offers no protection against that which is the whole point of a log in.

The "standard" way to go about it is to store the info in a database:

id¦delegation_id¦password¦content
123¦3456¦abcdef¦this is the content for delegation 1
124¦5656¦ghijkl¦this is the content for delegation 2 ....

You'd do the login validation and get the content, and if the login validates, display only content for that user.

header("content-type:text/html\n\n"); 
// mysql connect, get $row data based on input 
if( 
 ($_POST["userid"]==$row["delegation_id"]]) and 
 $_POST["password"]==$row["password"]]) 
 ) { 
 session_start(); 
 echo $row['content']; 
} 
else {  
echo "Login failed"; 
// add form here so they can try again 
} 

If you don't use a database, you can store the delegation data in files and create an array associating files with users:

<?php 
$users = array( 
 "user1" => "pass1", 
 "user2" = > "pass2", 
 "user3" => "pass3" 
); 
$files = array( 
 "user1" => "file1.txt", 
 "user2" = > "file2.txt", 
 "user3" => "file3.txt" 
); 
// a single multidimensional array here would work too 

header("content-type:text/html\n\n"); 
if ( 
 // Make sure "user1, user2..." is in the array 
 (array_key_exists($users[$_POST["username"]],$users)) and 
 ($_POST["password"] == $users[$_POST["username"]]) 
 ) { 
 session_start(); 
 $_SESSION["username"]=$_POST["username"]; 
 $content = file_get_contents($files[$_POST["username"]]); 
 echo $content; 
 exit; 
} 
else{ 
 $form=' 
 <p>Login failed, try again</p> 
 <form><!-- put login form here --></form> 
 '; 
 echo $form; 
 exit; 
} 
?> 

There are more details, such as cleansing input, etc. . . . but this would work and to maintain it you would only have to add entries to the database or modify the arrays, which could be pared off into a config file or something.
