Hi all, I have a problem with setting a session variable in a php script and then retrieving it in a template. It seems easy, and maybe it is, but I've struggled for several hours... In my pagelayout.tpl I've included the following code :
<p>My variable : {ezhttp('myvar','session')}</p>
<form method="post" action="/updateSession.php"> <input id="module_result_uri" type="hidden" name="module_result_uri" value="{$module_result.uri}" />
....
</form> The file updateSession.php looks like :
<?php
$redirect_uri = $_POST['module_result_uri'];
include_once( "lib/ezutils/classes/ezhttptool.php" );
$http =& eZHTTPTool::instance();
$http -> setSessionVariable('myvar','value'); header("location:$redirect_uri");
//print($http->sessionVariable('myvar'));print("<br/>");
//print($http->sessionId());
?> The principle is that when the form is submitted, the php script sets some session variables (normally with submitted values) and then the original page is displayed and session-saved variables should be available for later operations. The problem is that when the original page is displayed again, the line {ezhttp('myvar','session')} does not display any value. I'm not sure I have well understood how Exponential sessions work (is there a configuration to do to access session variables in a template?), but finding information about it is rather hard...
Any help or advice is really really welcome !
Thanks.
Emmanuel
