Can this be done successfully?

I've started with a php page which parses a template file. Inside that template I call another php page within the frame src tag.

eg.

<FRAMESET cols="20%">
<FRAMESET rows="180, 200">
<frame src="callLocations.php">
</frameset>

The callLocations.php in turn calls another template which would in turn display the contents for that frame.

This ends up not working as it should. Am I missing something? Any help would be most appreciated.

Hi,

Post the template code (just lines in cause)
and the callLocations.php (just lines in cause)

No enoug informations for the moment...

At the moment it's pretty bare; just testing to see if it works or not.

index.php

require_once("Smarty.class.php");
$smarty = new Smarty;
$smarty->display("index.tpl");

index.tpl

<FRAMESET cols="20%">
<FRAMESET rows="180, 200">
<frame src="callLocations.php">
</frameset>

callLocations.php

require_once("Smarty.class.php");
$smarty = new Smarty;
$smarty->display("temp.tpl");

temp.tpl

testing this out

Those are all the files.

If I understood your installation, the Smarty class not works like this.
You have to build your own class using the Smarty original one to configure with your environment.
You have to create several directories but take a look to PDF documentation for installation (examples included) at http://smarty.php.net/manual/en/installing.smarty.extended.php

Note : The HTML content should include bold text like behind :
<html>
<head>
</head>
<frameset cols = "25%,25%,*">
<frame src ="venus.htm">
<frame src ="sun.htm">
<frame src ="mercur.htm">
</frameset>
</html>

The installation of Smarty is fine. If I do not use frames, everything works great.

The problem occurs when I try to use a template instead of a straight up html file in the frame src tag.

My logic is thus. Once the template that includes the frame information is parsed, i need to show another frame with the data in it. The data that goes in this frame is dynamically generated thus I can't call a .html file. I must call a template file, but the only way to do this is to create another php file and call the template from there.

Perhaps I'm going about this the wrong way?

cage. your logic is correct. Your frame points to a php file that instantiates the template: should work! What exactly is wrong with the output?

Your <frameset> code is broken...( or at least missing some <frame>s), so it might not look like you expect (or the browser you are using may refuse to render it.)

Also, head Sri_Lumpa's advice on building valid html Smile

Hrm

I get the following error when I try to access the page:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:

It doesn't say what headers are returned.

Btw, I do normally write valid xhtml code, just being lazy atm. Smile

yipes.

I assume that when you browse to http://yoursite/callLocations.php directly, you don't get errors? callLocations.php is in the same path as your frameset.php, yes?

Argh! Boots, you have pointed out that I'm an idiot atm. I just noticed that my .php file was in my templates directory. Sad

I think I need a little more caffeine to wake me up this morning.

Thanks for the troubleshooting. Laughing

For information, the following code should works fine Laughing

:
(in fact, I didn't try it in this state because I have no access to any web server)

index.php source
<?php
require_once(".\\MySmartyClass.php");
session_start();

if(!isset($_SESSION["foo"])){
session_register("foo");
$_SESSION["foo"] = new MySmartyClass();
}
$_SESSION["foo"]->assign("sessionName", session_name());
$_SESSION["foo"]->assign("sessionID", session_id());

$cacheID = "index".session_id();
$_SESSION["foo"]->display("index.tpl", $cacheID);
?>

constants.conf
<?php
// The following repertories must have been created !!!
define("MYSITE_BASE_DIR" , "C:\\Inetpub\\wwwroot\\MySite\\");
define("SMARTY_BASE_DIR", "C:\\php\\Smarty\\");
define("MYSITE_TEMPLATE_DIR", MYSITE_BASE_DIR."templates");
define("MYSITE_COMPILE_DIR" , MYSITE_BASE_DIR."templates_c");
define("MYSITE_CONFIG_DIR" , MYSITE_BASE_DIR."configs");
define("MYSITE_CACHE_DIR" , MYSITE_BASE_DIR."cache");
?>

MySmartyClass.php source
<?php
include_once(".\\configs\\constants.conf");
require_once(SMARTY_BASE_DIR.'Smarty.class.php');
class MySmartyClass extends Smarty {
function MySmartyClass(){
$this->Smarty();
// Smarty using directories
$this->template_dir = MYSITE_TEMPLATE_DIR;
$this->compile_dir = MYSITE_COMPILE_DIR;
$this->config_dir = MYSITE_CONFIG_DIR;
$this->cache_dir = MYSITE_CACHE_DIR;
// Smarty configuration
$this->caching = TRUE;
$this->debugging = FALSE;
}
}
?>

index.tpl source
{* Smarty *}
<HTML>
<HEAD>
<TITLE>My HomePage</TITLE>
</HEAD>
<BODY>
<TABLE CLASS="MyFrames">
<TR>
<TD>
<IFRAME NAME="Frame1" SRC="frame1.php?{$sessionName}={$sessionID}">
</IFRAME>
</TD>
<TR>
<TD>
<IFRAME NAME="Frame2" SRC="frame2.php?{$sessionName}={$sessionID}>
</IFRAME>
</TD>
</TR>
</TABLE>
</BODY>
</HTML>

frame1.php source
<?php
include_once("MySmartyClass.php");
session_start();
if(!isset($_SESSION["foo"])){
// Direct access to frame is forbidden
// Manage error...
}
$cacheID = "frame1".session_id();
$_SESSION["foo"]->display("frame1.tpl", $cacheID);
?>

frame1.tpl source
<HTML>
<HEAD>
</HEAD>
<BODY>
Current user is identified by the following sessionID : {$sessionID}
<BODY>
</HTML>

Idem for frame2 files than for frame1 files

Sorry, it was a little long, but I'm at work Wink

Thanks for the detailed response Sri_Lumpa.

I was able to get these frames working and now ran into another little problem. Hopefully this will make some sense.

eg. this is pseudo code for the most part

index.php

smarty->assign("title","title");
smarty->display("frameset.tpl");

frameset.tpl

<frame name="left" src="callLocations.php">

callLocations.php

smarty-display("Locations.tpl");

Locations.tpl

{$title}

Now the problem is that I cannot pass the data from the original (index.php) to the Locations.tpl file. Since the Locations template is not called directly from the index.php the variables are not passed.

My question is: Can this be done?

I want to use frames but you must jump through a couple of hoops to get them displaying properly because of the use of templates.

Sri_Lumpa · Posted: Fri Apr 25, 2003 1:53 pm Post subject:

That's the aim of passing session ID to frames files.
PHP files (which call frame templates) retrieve the Smarty object registered in the user session (add session parameters to URL make the session_start() function recognize session data) and so, to the templates...
