[Resolved] submited variable to be available to all pages

Fking

i have a form field i want when the value there is entered and submited it to be available to all pages till the user close the browser.
What's the best way to do that?

Im thinking cookies would be the best thing if not the only thing... but sorry i dont know anything about cookies or how to use them 🙁

i would advise you to use sessions.

heres a little example.

Page1.htm (your form)

<html>
<body>
<form action="page2.php" method="post">
<input type="text" name="newvar" size="30">
<input type="submit" value="submit" name="submit">
</form>
</body>
</html>

Page2.php (creates the sessions)

<?php
session_start(); // you MUST call this before ANYTHING else! otherwise you will get errors

if (!empty($_POST['submit'])) {
	$_SESSION['varname'] = $_POST['newvar']; // set session variable to whatever was inputted
}
else {
	Header('Location: Page1.htm');
}
?>

Any other php page
to simply call back your input just place this wherever you want it outputted

<?php
echo $_SESSION['varname'];
?>

hth, Jon

thanks!
exactly what i need

Fking

after many unsucessful attemps to build this for my needs
i decided to create 3 sample pages exactly with the code you provided to see if it doesn't work cause of my mistake or cause of something with the server
page1.htm is the same code
to page2.php below your code i added link which leads to page3.php
where the only code is
<?php
echo $_SESSION['varname'];
?>

and it does not output it...

what may be the reason?

p.s. as i know if it can't create a cookie it adds a sessionid to the url
well i don't have cookie neither SID string added to the url....

tuf-web_co_uk

sorry i forgot to inform you that you must also place

<?php
session_start();
?>

on any page you wish to call session variables

Fking

ok the code of 3rd page now is

<?
session_start();
echo $SESSION['varname'];
?>

but still does not output it....

the support of the hosting says it's nothing to do with their configs......

Fking

and still doesn't set cookie or SID string to the urls...

Fking

i tested it aslo with clean IE6, opera and firefox
it adds a SID string to the url, but only the first time when i try and still does not output the variable on the 3rd page

i'm totally confused.....

Fking

i made it
thanks!
