Hi,

I am writing a simple template engine for my site, to make changes to layout and styling easier.

 

At present, it's basically just an object-oriented find-and-replace script ie. replace {PAGE_TITLE} with the title of the page.

 

I am stuck at the point of looping variables/database rows. How would one pass an array to the template, or make the template loop over multiple database rows, to output news items or menu items etc.

 

I have looked into template engines already out there like Smarty, but I would like something fast and simple, as my site isn't very large yet, and I want to keep load times as low as I can (I will be writing a caching system once the engine is completed).

 

Thanks for any help,

 

Rob

I would suggest

 

http://ets.sourceforge.net/

 

1 file, very easy and very simple.

 

Smarty is overly complex for most people. With the above once you have the file built to call the template it is simply

 

printt('template.tpl', $etsobject);

 

Building your own template system is a lot of work, especially with the looping portion and conditional system. I would highly suggest looking into the above. I use it on some of my code and it has yet to fail me on being speedy etc.

Well, this is more of a fun project than anything, I want to be able to maintain my own code, and know exactly how everything works. I much prefer running my own code, but if this becomes a huge project, then I will consider using ETS.

 

If anyone knows a way to have a preg_replace() or similar function loop over a string for a given array (ie. in a foreach or something?), then I would be extremely grateful.

 

Thanks for the reply,

 

Rob

The whole thing is that once you start trying to impliment loops and conditionals within templates, your simple template engine is no longer simple.

 

Ive never bothered with templates or template engines. IMO, PHP is a template engine.

Well, maybe this will help you out. I created my own "Template system" a few years back, with the same attitude as yours. At any rate it does loops, but probably not as efficiently as it could be. Hope this will help you out trying to figure out what you need for the loopage part:

 

<?php
//Template Script v1.1
/*
These are the functions that make the script work
Do not edit these any type of editing may make it not work right.

Hope it helps.

My only other idea for this would be to cheat, and have the PHP construct the loop into a variable, and then pass that to the template so all it would need to do it display the contents.

 

ie.

<?php
$menu = '';
while ($row = mysql_fetch_array($sql))
{
  $menu .="<a href='".$row['href']."'>".$row['title']."</a><br />";
}
?>

 

But that's not very neat at all, and I can't figure out any other way to solve the problem, is there an elegant solution that is simpler, or would my template system have to become very complicated to handle such functions.

 

Thanks for all the help,

 

Rob

 

P.S. I will have a good look through that code, frost110, thanks for posting it!

Well, I finished it today  ;D

 

I don't know how clear or "proper" my code it, but it's my first attempt at a neat, object-oriented project, so here's the main template code:

 

<?php

class template
{

var $page;
var $template_path = "templates/";

var $vars;
var $tpl_data;
var $cur_loop;

/*
/* Constructor
*/
function template($template)
{
	// Check if template file exists
	if (file_exists($this->template_path . $template))
	{
		// Load contents into $this->page
		if (!$this->page = file_get_contents($this->template_path . $template))
		{
			die ("Error loading template");
		}
	}
	else
	{
		die("Could not find template file");
	}
}

function assign_var($varname, $varval)
{
	$this->vars[$varname] = $varval;
	return true;
}

function assign_vars($vararray)
{
	foreach ($vararray as $key => $val)
	{
		$this->vars[$key] = $val;
	}

	return true;
}

function assign_block_vars($blockname, $vararray)
{		
	// Add a new iteration to this block with the variable assignments we were given.
	$this->tpl_data[$blockname][] = $vararray;
}

function loops()
{
	foreach($this->tpl_data as $loop => $vararray)
	{
		$this->cur_loop = $this->tpl_data[$loop];
		$this->page = preg_replace_callback('^<!--\s?LOOP\s('.$loop.')\s?-->(.+)<!--\s?END\sLOOP\s?-->^si', array('template', 'loop_callback'), $this->page);
	}
}

function loop_callback($matches)
{
	$result = '';
	foreach ($this->cur_loop as $vararray)
	{
		foreach ($vararray as $key => $val)
		{
			$result .= str_replace("{".$key."}", $val, $matches[2]);
		}
	}
	return $result;
}

function compile()
{
	$this->loops();
	foreach ($this->vars as $key => $val)
	{
		$this->page = str_replace("{".$key."}", $val, $this->page);
	}
}

function output() {
	$this->compile();
	print $this->page;
}
}
?>

 

It would be great if you had any tips or warnings about things that I may have done wrong, I need to make sure the code is OK before putting it into production :)

 

Thanks for the help,

 

Rob
