Functional FIPSPHP for Drupal Designers and Themers
www.hicktech.com@emmajanedotnet
About this talk● There are a lot of theme snippets available in the Theme Guide. There
is not, however, a lot of information about PHP which is the language that makes up these snippets. If you're tired of copying, pasting and praying and are ready to understand some of the magic behind those snippets, this session is for you!
● In this session you will learn how to manipulate and master:
● The very, very basics of PHP and the popular theming engine PHPtemplate
● Variables and tpl.php template files
● Arrays and objects and other crowbarworthy data containers.
● The really scary looking stuff that's in the mysterious file template.php
● Examples will be pulled from the Drupal.org Theme Guide as well as the wildly successful book on theming, Front End Drupal (coauthored by Emma Jane and Konstantin Kaefer).
Stick around, I've got copies to give away.

How to create themes
1.Download an existing theme.
2.Look for variables and functions.
3.Alter the placement of the “printed” things.
4.Save and upload the theme files.
5.Clear the theme registry (Drupal admin).
6.Enjoy your new theme.

Zomg what are those variables?
● Look at /modules/system/page.tpl.php
OR● http://api.drupal.org/api/drupal/modules
systempage.tpl.php/6

What's an “if”?
if ($logo) {
<?php print ?>
}
Fancy data structures: arrays + objectsGrouping and sorting your data
Fancy data structures: arrays
Multiple values stored in one array
Multiple “drawers” of sorted content

“Advanced” PHP
● Never be afraid to try something.● Always back up your files first.● Take a LOT of notes.● Be bold! And be brave!
template.php: what's up with that?
● Preparing variables that weren't assembled by Drupal and its modules.
● Altering the contents of variables that were prepared by Drupal and its modules.
● Special theming functions to do fun things like 'edit this block' links and random images.
● Read the Zen base theme documentation and template.php file.
Using template.php
Collect the content from Drupal using modules and run it through the
default theme functions provided by Drupal.
Create new Create new information to feed information to feed
to your themeto your theme
Print the variables in your template

PHP Snippetfrom: http://drupal.org/node/21401
<?php if ($submitted) { ?><span class="submitted"><?php if ($node>type == 'blog') { print 'Posted ' . format_date($node>created, 'custom', "F jS, Y") . ' by ' . theme('username', $node); } else { print 'By ' . theme('username', $node) . ' <br /> ' . format_date($node>created, 'custom', "F jS, Y") ; } ?></span><?php } ?>
Summarizing PHP for Designers
● PHP is a linear “programming” language, just like a dance.
● PHP stores information in variables.● Sometimes variables hold lots of information
in special variables called “arrays.”● Drupal has lots of magic variables that are
loaded with content. Check out: http://drupal.org/themeguide
