New to php, Help about page passwod

[princeo]

iam new to php and i believe its a great tool in doing this, I have a username and a password on my home page.

what i want to do is have a predefined username and password to direct to a particular page. i dont want to get db involved in this. in other words i want to password a particular page from every body except the people i want them to have the username and password.

 

can anyone give an understandable tutorial in achieving this? i will so much appreciate it.

somthing like this?

if($_GET['password'] == '1password') {
$_SESSION['loggedin'] == true;
$_SESSION['password'] == '1';
header('Location: http://yoursite.com/1link.php');
}else if($_GET['password'] == '2password') {
$_SESSION['loggedin'] == true;
$_SESSION['password'] == '2';
header('Location: http://yoursite.com/2link.php');
}

Thanks for the code, but u never mentioned which page to insert the code and what i should modify in the code. remember i told u iam new to php. i would most appreciate if u take out ur valuable time and teach me as a novice. thanks

you could have a page like loginp.php

with the code

<?php
session_start();
if($_GET['password'] == '1password') {
$_SESSION['loggedin'] == true;
$_SESSION['password'] == '1';
header('Location: http://yoursite.com/1link.php');
}else if($_GET['password'] == '2password') {
$_SESSION['loggedin'] == true;
$_SESSION['password'] == '2';
header('Location: http://yoursite.com/2link.php');
}else
header('Location: htttp://yousite.com');
}
?>

I modified the code and placed it into the body of a page i named information.php, this is the code

 

<?php

session_start();

if($_GET['password'] == '1password') {

$_SESSION['loggedin'] == zane;

$_SESSION['password'] == 'zane';

header('Location: http://zanedesignsltd.com/information.php');

}else if($_GET['password'] == '2password') {

$_SESSION['loggedin'] == zane;

$_SESSION['password'] == 'zane';

header('Location: http://zanedesignsltd.com/information.php');

}else

header('Location: htttp://zanedesignsltd');

}

?>

 

when i log in it displays this following message, pls i still need your help

 

 

Parse error: syntax error, unexpected '}' in /home/zanedesi/public_html/information.php on line 21

1. Strings need to be quoted

  $_SESSION['loggedin'] = 'zane';

2. To set values use a single equals sign, to test values use double

3. Your missing a { after the else

4. Your url had htttp and didnt have .com

5. By the sounds of it its in the middle of the page by the error line you said, your going to get header() errors, so put this at the top of the file.

 

<?php
session_start();
if($_GET['password'] == '1password') {
$_SESSION['loggedin'] = 'zane';
$_SESSION['password'] = 'zane';
header('Location: http://zanedesignsltd.com/information.php');
}else if($_GET['password'] == '2password') {
$_SESSION['loggedin'] = 'zane';
$_SESSION['password'] = 'zane';
header('Location: http://zanedesignsltd.com/information.php');
}else {
header('Location: http://zanedesignsltd.com');
}
?>

it actually went to the page specified but it displayed with the following information, what do i do again? please explain to me as a novice.

 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/zanedesi/public_html/information.php:9) in /home/zanedesi/public_html/information.php on line 10

[ReDucTor]

the code must be at the VERY top of the page.

[princeo]

iam using dreamweaver, where exactly should i put the code?

[princeo]

It keep on showing these two errors.

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/zanedesi/public_html/information.php:3) in /home/zanedesi/public_html/information.php on line 4

 

Warning: Cannot modify header information - headers already sent by (output started at /home/zanedesi/public_html/information.php:3) in /home/zanedesi/public_html/information.php on line 14

 

 

this is what is on line 4

session_start();

 

then line 14

header('Location: http://zanedesignsltd.com');

 

iam sorry bothering you, i desperately need to solve this issue urgently.

Just a tip: Don't use dreamweaver - you need to learn what the code is doing and if it's doing it for you you won't understand.

 

What is on lines 1-3?

[princeo]

the code must be at the VERY top of the page.

 

I have been very happy with your supports but this thing is still giving a hell of headache, check out my last post and help me out please.

[nathanmaxsonadil]

What is on lines 1-3?

[princeo]

This is actually what shows up

 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/zanedesi/public_html/information.php:2) in /home/zanedesi/public_html/information.php on line 3

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/zanedesi/public_html/information.php:2) in /home/zanedesi/public_html/information.php on line 3

 

Warning: Cannot modify header information - headers already sent by (output started at /home/zanedesi/public_html/information.php:2) in /home/zanedesi/public_html/information.php on line 13

 

This the code according to how it appears in dreamweaver

 

1.  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

2.  <?php

3.  session_start();

4.  if($_GET['password'] == '1password') {

5.  $_SESSION['loggedin'] = 'zane';

6.  $_SESSION['password'] = 'zane';

7.  header('Location: http://zanedesignsltd.com/information.php');

8.  }else if($_GET['password'] == '2password') {

9.  $_SESSION['loggedin'] = 'zane';

10. $_SESSION['password'] = 'zane';

11. header('Location: http://zanedesignsltd.com/information.php');

12. }else {

13. header('Location: http://zanedesignsltd.com');

14. }

the problem is that you have this 1.  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  on top
