== Felder mit Templates rendern ==
ProcessWire rendert Felder mit einem Template wenn es in /site/templates/fields/ liegt und richtig benannt ist.

Beispiel

/site/templates/fields/body.php

<syntaxhighlight lang="php">
<div class='bodycopy'>
  <?= $value ?>
</div>
</syntaxhighlight>

Ausgabe z.B. mit:

<syntaxhighlight lang="php">
echo $page->render('body');
echo $page->render->body;
echo $page->_body_; // Nützlicher Shortcut wenn man mehrere Felder mit Template ausgeben möchte.
</syntaxhighlight>

Es stehen folgende Variablen zur Verfügung:
    $value - The value that needs to be rendered
    $page - The page that $value lives on
    $field - The field representing $value (of class Field) if you want it
