PHP Template System Class

[Hitch]

Hey,

So, i made this Class a while ago, for a project, then decided to post it on my blog, and now, here.

It's the sort of system PhpBB uses.
You can use .html/.tpl files etc, and use the {tags}

You can use variables for "replacement" too.
Check out the class, then i will explain how to use it.

// Feel free to use this code in your own scripts.

class Tpl
{
	var $file;	

	function file($user_file)
	{
		if(file_exists($user_file))
		{
			$this->file = file_get_contents("" . $user_file . "");
		}
		else
		{
			die ("Sorry, the following file, " . $user_file . " could not be found.");
		}
	}

	function replacement($tags = array())
	{
		if(count($tags) == 0)
		{
			die ("No tags defined for Template Tag replacement.");
		}
		else
		{
			foreach($tags AS $tag => $replace)
			{
				$this->file = str_replace("{" . $tag . "}", $replace, $this->file);
			}
		}
	}
	
	function display()
	{
		echo $this->file;
	}
}

$tpl = new tpl;

?>

This is how to use it.

<?php

require "tpl_class.php";

$tpl->file("template_design.html");

$tpl->replacement(array(
	"sitename" => "Dream It",
	"slogan" => "The Technology Blog",
	"footer" => "Copyright to Adrian at Dreamit.co.uk"
));

$tpl->display();

?>

Ok, and a example of your .tpl/.html file would be...

<h2>Welcome to {sitename}</h2>
{slogan}
<hr>
Hello, this would be some content.
<hr>
{footer}

When i said variables earlier, you could use them like this. (Lets get the Sitename from the MySql DB, the sort of thing to use in a CMS)
Also, lets say we want to use a specific "theme/template", which the template name/path is stored in the DB.

<?php

require "tpl_class.php";

$get_settings = mysql_query("SELECT * FROM `settings`") or die ("Cannot get settings.");
$setting = mysql_fetch_array($get_settings);

$tpl->file("templates/" . $setting['style'] . "/header.tpl");

$var = "This var could also be used in the Replacement.";

$tpl->replacement(array(
	"sitename" => $setting['sitename'],
	"slogan" => "The Technology Blog",
	"footer" => "Copyright to Adrian at " . $setting['sitename'] . ""
));

$tpl->display();

?>

Last example, lets say you have the function in your CMS/Site, to enable/disable the CMS.
Like vBulletin...
Right, lets say, our "Disabled Page" is called offline.tpl

You could use...

<?php

require "tpl_class.php";

$get_settings = mysql_query("SELECT * FROM `settings`") or die ("Cannot get settings.");
$setting = mysql_fetch_array($get_settings);

if($setting['online'] == 0)
{
	$tpl->file("templates/" . $setting['style'] . "/offline.tpl");
} else if ($setting['online'] == 1)
{
	$tpl->file("templates/" . $setting['style'] . "/index.tpl");
}

$tpl->replacement(array(
	"sitename" => $setting['sitename'],
	"slogan" => "The Technology Blog",
	"footer" => "Copyright to Adrian at " . $setting['sitename'] . ""
));

$tpl->display();

?>

You can use sortable tables and such, and still display them via this Class.

Hope you find it useful. :tu:
Rep' is appreciated.

Nice simple class, rep++

 

[beaver6813]

Taken some of the techniques from your script

while($allowed_to_give_rep==0){
echo "Waiting to be allowed to give Hitch rep";
sleep(60);
check_allowed();
}
$Rep++;

Sam, Lol.

Ah, thanks, a nice and simple template class.
The smarty one made by the php people really confuses me :S

btw, if I wanted to include the files, header.tpl, body.tpl and footer.tpl, would I have to have multiple instances of $tpl->file("file"); ?
