I'm a beginner at smarty and having difficulty working out a standard method to include frames and message boxes into my pages.

Here is the code I have and how I want it to function. I've been trying different methods for the last three days and ending nowhere:

index.php

Code:
$smarty->display('mypage.tpl')
;
mypage.tpl
Code:

{extends 'main_frame.tpl'}

{block 'title'}This is an example{/block}

{block 'body'}
  <p>This page is built with smarty</p>

  {extends 'message_box.tpl'}
  {block 'body'}
    <h1>Smarty is fun</h1>
  {/block}

{/block}

main_frame.tpl

Code:
<html>
  <head>
    <title>{block 'title'}{/block}{/title}
  </head>
  <body>{block 'body'}{/block}</body>
</html>

message_box.tpl
Code:

<div style='boarder: thin solid #f0f0f0;'>
  {block 'body'}{/block}
</div>

The rendered code should be something like this:
Code:

<html>
  <head>
    <title>This is an example{/title}
  </head>
  <body>
    <p>This page is built with smarty</p>
    <div style='boarder: thin solid #f0f0f0;'>
      <h1>Smarty is fun</h1>
    </div>
  </body>
</html>

1. No, you can not randomly disperse {extends} through the template. Only one is allowed, but you may list a chain of templates in PHP code. They will be extend'ing each other in order, effectively resulting in one template, again.
See https://www.smarty.net/docs/en/resources.extends.tpl

2. In extending template, only top-level elements allowed are {extends} {block}'s and comments.
No clear text, nothing else is allowed.

3. Another point is that you confuse formatting and content.

Thus, your solution is:

index.smarty:
Code:
<html>
  <head>
    <title>{block 'title'}Default title{/block}</title>
  </head>
  <body>{block 'body'}{block 'content'}No content.{/block}{/block}</body>
</html>


message_box.smarty:
Code:
{block 'body'}<div style='boarder: thin solid #f0f0f0;'>
  {block 'content'}Message without content.{/block}
</div>{/block}


my_message.smarty:
Code:
{extends 'message_box.smarty'}

{block 'title'}This is an example{/block}

{block 'body'}
  <p>This page is built with smarty</p>

  {block 'content'}{child}{/block}

{/block}

AnrDaemon,

Thank you for participating. I understand the work of extends but I was looking for a method to call templete into a template.

My example was very simple. The actual code is more decorative. The message box has title body and footer sections.
Sometime it will be used to only print a message while other times it may contain inputs and buttons

So to expand my example

Message box may looks like

Code:

<div class=messagebox>
<div class=header>
<h1>{block title} title {/block} </h1>
</div>
<div class=body>
{block body} {/block}
</div>
<div class footer>
{block footer} {/block}
</div>
</div>


Basically I want to include template message box to the page at specific position. It will be unreliable to do so with {function}.
Any clue how to approach it?

So, use {include}, not {extends}.

If I use include I cannot change the blocks of the included file (I tried)

Of course.

Again, you can extend only one template.

You can try using "extends:..." as a source of a template you extend (can't test ATM), but again, it will be a single resulting template you extend with your one.

Think again, and use right tools for what you want to achieve.

That isn't the solution I hopped for.

I wanted a method where I can {include} template and change its {block}
