Sending a value with 'onClick'

[essjay_d12]

I want to send a php variable (the current URL) to a new .php file without doing it through a form/hidden field - but i need a button - so i though I could do it somehow with 'onClick'? Is this possible and how?

 

cheers

cookie or sessions would work

[vbnullchar]

you should have an idea

 

<?php
if(!$c_employee->isLogged()) {
	/* encrypt query string */
	$url=base64_encode($config['site_root'].'?'.$_SERVER['QUERY_STRING']);
	header("Location: index.php?url=".$url);
	exit();
}

?>

or just send it via get...

<a href="location.php?variable=string">text</a>

 

then

echo $_GET[variable];

all true i thought he wanted it visible to the page..

should of read twice! lol

I am now trying to do it with sessions - the page I am sending it to is a pop up window yet it doesnt seem to echo out the session when I know it has set correctly in the previous page. here is my code

 

first page

session_start;
function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
	$pageURL .= "://";
	if ($_SERVER["SERVER_PORT"] != "80") {
		 $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
	} else {
  		$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
	}
	return $pageURL;
}
$_SESSION['URL'] = curPageURL();
echo $_SESSION['URL'];
echo "<input type=\"button\" name=\"web_data\" value=\"Web Page ...\" ".
             "onclick=\"return window.open('http://localhost/page2.php', 'web_data', 'menubar=1,location=1,directories=1,toolbar=1,scrollbars,resizable,width=800,height=600');\" />\n";

the Correct URL and button appears

 

Page 2

session_start;
echo $_SESSION['URL'];
echo " Hello";

 

But only hello appears!!!

 

Anybody explain?

 

cheers

try

<?php
session_start();
?>

instead of

<?php
session_start;
?>

[essjay_d12]

still doesnt display it

[essjay_d12]

There are many other pages conflicting with this file, which may be doing a session_destroy - i cant view them to find out, is there another way (instead of sessions) how would I do the same thing using the function but possibly with cookies etc or any other ways?

4 ways of transfering data page to page... get, post, sessions, cookies... if sessions are scratched, the next one that you prolly want to use for that is either get(use once(ish)), or cookies(use many times)...
