PHP function works in php5 but not live in php4 - PEAR

Bullit

Hi there
I am new to php - but getting on well with it.
My script below works when I test locally - but not when I go live.

I have a function to fill a dropdown box with data from a database.
I pass a connection and a PEAR .tpl file object to the function.
The function uses the two and adds the necessary dropdown details for output.
It all works locally.

It will not work this way when it goes live.

As a test I stripped out the functions and put their code in-line where they were required.
This worked. It suggests to me that I cant pass a template object to a function and get the result I need in the live setting.
My host uses: PHP Version 4.3.11

I use PHP Version 5.0.4 locally.
Is php 5 letting me away with something it shouldn't?

How can I make this work for my live environment?

Any Help much appreciated.

Thanks
Bullit

<?php
.
.
.

function filldropdownbox($connection, $template){
//sql to get the headings to fill

		$template->setCurrentBlock("USERENTRY");
		//for each result build an option value and row pairing
		while ($deptrow = mysql_fetch_array($SQLresult)) 
			{
			$optionvalue = $deptrow["dept_id"];
			$optionrow = $deptrow["deptname"];
			$template->setCurrentBlock("DEPTINPUT");
			$template->setVariable("OPTIONVALUE",$optionvalue);
			$template->setVariable("OPTIONROW",$optionrow);
			$template->parseCurrentBlock();
			} //endwhile
			$template->parseCurrentBlock();
	}//end func loaddeptdropdown

//connect to server

//select database

$template = new HTML_Template_ITX("./templates");
$template->loadTemplatefile("enterusers.tpl", true, true);

//call the function
loaddeptdropdown($connection, $template);

//call more dropdown box filling functions
//then finally
$template->show();

does your host have pear installed? it is seperate from php.

Installer

It looks to me like HTML_Template_ITX is written for PHP5 with no backward compatability. Do you have error reporting turned on for the live server?

Bullit

I am pretty sure PEAR is installed. The page shows.
And phpinfo() gives ".:/usr/local/lib/php:/usr/local/lib/php/PEAR"
In the results

Installer: how do I turn error reporting on? I see the errors when my php code is bad / or a type-o.

My suspicion to the problem is that I am not passing the template correctly, or need to return a template value.. is that not the case?
I am passing $template to the function and then altering template locally in the function and php5 is letting me away with it but 4 is not?

Also as mentioned --- when I strip the functions and just put them in as in-line code the script works fully.
It must be something to do with the way I am calling the function

Anymore input - very very welcome
Thanks guys

put this at the top of your script;

error_reporting(E_ALL);

Bullit

I put that in. No errors came up.

What I'm doing wrong is defo something to do with paramater passing, var scope or the order im building my template in - but I can't spot it

Bullit

figured it out

needed an ampersand &

function filldropdownbox($connection, &$template)

funny that php5 was lettin me away with it

Thanks for all help folks

Edit: Never mind.

Now that I've found the docs for the right class, I can see that it is (or should be) campatible.

If you're getting error messages, you must have error reporting on, but you can make sure by putting this at the top of the script:

ini_set('error_reporting', E_ALL);
ini_set('display_errors', 1);

Try that and see if you get any informative messages.
