Sessions for one variable?

imnsi

Ok I am going to be making a membership database (in all of my hopes) and I need to check things against my database using only one variable, an email. But I want to be able to always look up this variable from any of the pages (once they login.) what is the best way to do this. Do I need sessions, can I post it into a frame and then get it from there somehow?

Whats the best way to handle passing one variable thru multiple frames/pages/scripts?

Besting meaning easiest and somewhat secure. 🙂

Also, how do I just link so like..

if (checkpw == password) {

//link to correct

} else {

//link to incorrect

};

by link i mean directly open a certain page

There are generally 2 ways of doing what you want: Cookies or Sessions.

I have used sessions more than cookies because they are easier. I am unsure which method is more secure though.

Also, how do I just link so like..

if (checkpw == password) {

//link to correct

} else {

//link to incorrect

};

by link i mean directly open a certain page

//login.php
session_start();
if ($checkpw==$password){
    $_SESSION['user_email']=$user_email;
    session_write_close();//may not be neccesary 
    header ("Referesh: 0; url=secretpage.php");
    die();//in case something goes wrong.
}

else{
    header ("Referesh: 0; url=incorrectpage.php");
    die();//in case something goes wrong.
}


//secret.php
session_start();

if(!isset($_SESSION['user_email'])){//if the sesssion isn't set
    header ("Referesh: 0; url=login.php");
    die();   

}
else{
//do the secret stuff
}

I get a problem at....

Fatal error: Call to unsupported or undefined function session_start() in /u/htdocs/nibode/SQL/members/login.php on line 35

would using MySQL have anything to do with it?
