i was doing a test to see if i could do some sort of login thing on my website, i cant get it to display my name variable...

here are my troubled scripts with url of moopher.php?name=yabberyabber
Code: PHP - Show / hide line numbering

<?php
if (isset($_Get['name'])){
echo $_GET['name'];
}
else
echo "account"
?>
// and:
<?php
if (isset($_Get['name'])){
echo "<a href=\"logout.php\">logout</a>";
}
else
echo "<a href=\"welcom.php\">login</a>";
?>

my problem is that when i ttest it out (logging in from a separate page using PHP of course) instead if displaying yabberyabber, it displays account... and the link doesn't change to logout...

Hello, first in the page where you will get the veriables, use a ting like that for the links :

Code: PHP - Show / hide line numbering

http://www.website.com/infos.php?day=27&mount=07&year=2003&title=Informations

And for the page will receive te veriable, use a ting like that :

Code: PHP - Show / hide line numbering

<p>Your fisrt name is <?php echo $_GET['name']; ?> , and your last name <?php echo $_GET['lastname']; ?>.</p>

Edit : I think you have miss to put the signe ; after your $_Get. Try this :

Code: PHP - Show / hide line numbering

<?php
if (isset($_Get['name'];)){
echo $_GET['name'];
}
else
echo "account"
?>
// and:
<?php
if (isset($_Get['name'];)){
echo "<a href=\"logout.php\">logout</a>";
}
else
echo "<a href=\"welcom.php\">login</a>";
?>

I'm not sure about the last ting.

See you next time.

$_GET must always be in upper case

thanks speedking, but i have a new problem now. i decided to use cookies (with the tizag tutoreal...) but the tutoreal didn't explain very well... and i cant get my script to pick up the cookie (web developer tool bar doesn't say it was even made...) so here is my new troubled code:(using the basic code from the protecting website from intruders tutoreal...)
Code: PHP - Show / hide line numbering

$user_name = $_POST['user_name']; //i know theres no problem with this line because
setcookie('name', $user_name); //the tutoreal i used said if you don't set expiration, it will die when you close browser window...

but heres also the code for picking up the variable:
Code: PHP - Show / hide line numbering

if(isset($_COOKIE['user_name'])){
echo $_COOKIE['user_name'];
}

srry if i missed something redundant and/or obvious... ohh yea, and the example on Tizag doesn't work...
thanks in advance

ok so i just figured out that it is creating cookies, but they are only working for the file that created it... and the cookie wont stay for my 'home page'fixed it! i just had to have them in the same folder... (i wish Tizag would have told me that in their tutoreal...)

sorry for unearthing and adding yet another question to this topic but...

is there a way to made cookies last forever? i finally got the hang of them and i was trying to make the member zone (from the php tutoreal example) so that it would automatically log in when i went there (and no its still on my hard drive...)

You cannot set a cookie forever, but you can make it last, hum, let's say 50 years

Code: PHP - Show / hide line numbering

<?php
setcookie('my cookie', 'its value', time() + 3600*24*365.25*50);

Or 10 years
Code: PHP - Show / hide line numbering

<?php
setcookie('my cookie', 'its value', time() + 3600*24*365.25*10);

or 100
Code: PHP - Show / hide line numbering

<?php
setcookie('my cookie', 'its value', time() + 3600*24*365.25*100);

etc...

Won't go further than 2036 though (that's the maximum the 32-bits unix counter can handle).

...unless your server has a 64x processor and that your version of php handles it (php6?)

sorry for again unearthing and adding yet another question to this topic but...

does NP use sessions or cookies for account login stuff? i have a good source and understand both of them, but which one is most standard (i hate being off standard). and how does NP keep account info secure so you cannot hack into others accounts? is it simply hashing (md5();) user name and password then checking with the database on each page load? or is it something more. is that kind of info even safe to share with people (is security of accounts that important if its not really anything dealing with money?).

next time i have a question on php should i start a new topic or just keep adding on this for a while?

yabberyabber: when you log in on NP, it compares your password's sha1 hash with the one stocked in the database. If you can log in, it will place a variable in the session data (like for example $_SESSION['logged_in']), which will be used to make the website remember you are logged in.

so $_SESSION['logged_in'] is just a bool value? and then when they leave it just says "session destroy"

Trust nobody, do it yourself !

$_SESSION may contain chars like : "A b c d, 0 1 2 3 4 ... , TRUE / FALSE". (If not, It works for me xD)

I don't know if it's solved but $_SESSION is a way easier than $_COOKIE (for me) .
Code: PHP

<?php
if(isset($_SESSION['Member']))
{
 echo("You are logged");
}
else
{
 echo("You are not logged");
}
?>

Create a form which will create a member access (just a simple):
Code: PHP

<?php
if(isset($_POST['member_name']))
{
 $_SESSION['Member'] = $_POST['member_name'];
}
?>

After, go to the page where the first code was placed. If the sessions work correctly, you should see : You are logged.
However, if the session doesn't work, it should return you : You are not logged

After, you can create a page which will destroy all session vars :
Code: PHP

<?php
if(isset($_SESSION))
{
 // erase all sessions. I think you may specify which one you want to destroy. Refer to the manual
 session_destroy();
 header("Location: index.php");
}
else
{
 header("Location: index.php");
}
?>

If you still get the "You are logged" message, it means that the session_destroy() doesn't work (for any reason).
