Smarty

[Ragnarok]

Hi guys!
I just started to learn about smarty and i have a question.
I need implement a system where designer can write in template something like this:

<a href="$BASE_URL">Home</a>
Hello dear user!
You are watching article {$MyTag-ArticleTitle} on the {$FULL_URL} posted by {$MyTag-Author}

And user could see the title of current article on the page. So i need to assign the $ArticleTitle variable.
How can i do it? I mean i need to write a plugin that will check all the varibles in the template and if the first word of variable is "MyTag", value provided by me should be assigned to this variable. I can't just do it from controller, because there can a lot of tpl's or controllers, so i need the one place for code.
And the second this function should know current url to i can get currentarticle by url www.cms.local/articles.php?article="hello_world"

Thank you!

sounds like you are making this way too complicated.

I don't quite understand what you are trying to do, but maybe you could just have a separate variable called mytag? If that's not the solution, you really need to rethink how you are doing this.

<?php
/*
* Smarty plugin
* -------------------------------------------------------------
* File: function.tag.php
* Type: function
* Name: tag
* Purpose: assign a value to a template variable
* -------------------------------------------------------------
*/
function smarty_function_tag($tag, &$smarty)
{
$url = $_SERVER['REQUEST_URI'];
$res = "123";
if (is_array($res)) $smarty->assign("t", $res);
else return $res;
}
?>

and then in template
{tag t="ex-categoryAlias-title"}
