separation templates - business logic

[helmut2509]

Hello,
I am just programming a pw application with
user forms and a lot of data processing (getting
data from webservice, sending to webservice etc..).

Now I don't like to mess up the Html in the templates
with business logic, I want I neat separation of
concerns.
Are there any *best practices* how to handle this
with processwire?

Look through these links:

Go with Smarty there's a module for Smarty it's what i use if you are familiar with Twig, ASP Master Pages and all it's similar let me post some codes

[qtguru]

This is the main layout where other sub templates will be injected into

plain.tpl

<div class="header-container" id="header-container">

<!-- Site navigation -->
  {include '../elements/nav.tpl'}

  <!-- The title of the site -->


</div>

      <div class="wrapper">
        <div class="page-content">
          <div class="post">

  <header class="post-header">
    <h1 class="post-title">{$page->title}</h1>
    <p class="post-meta">{$page->published|date_format:"%A, %e %B %Y"}</p>
  </header>

  <!-- Beginning Twitter sharing Large button -->
  <a class="twitter-share-button" href="https://twitter.com/share"
  data-related="twitterdev"
  data-size="large"
  data-count="horizontal">
  Tweet
  </a>
  <!-- End of Twitter sharing button -->

  <article class="post-content">
    {block name="content"}{/block}

  </article>

  <hr>

Notice the block name "content" assuming a visitor navigates to my about page here is the file for the about view

about.tpl

 

{extends '../layout/plain.tpl'}

{block name="content"}
    
                          
                           {$page->body}
                           
                       
{/block}

See how clean and easy it is

@Sephiroth What about caching and performance? Does Smarty module respect template cache settings or it has an own caching system? 

[qtguru]

Yes it does there's a setting for caching and lifetime, I think it's using Smarty Caching only gives you an interface around it, here is the module
