Hello to all! :-)
Today i surprised myself thinking about how to use the HUGE themes
base of WordPress blog platform in our beloved drupal.
It's not trivial if u straight convert the CSS and you edit a bit the
usual page.tpl.php, block.tpl.php and so, but it's not what i have in
mind. My idea is to have the exactly same look of a wordpress site/
theme only replacing WP-API function calls (so that would be very
easy to make a wrapper or a wp- engine around phptemplate?).
It means that, since i strickly won't change style.css that the html
output of various pages MUST be exactly the same
A WP layout is more or less a reduced version of a drupal one
(limited to two to three regions). For those unfamiliar with WP,
newest themes already use the widget paradigm that is very similar to
But since the layout possibilities of WP are slighty limited,
designers very often still hardcode something in theme pages (usually
categories list, recent posts and 'meta' items). That's held the problem
(remember my needs: 1. same XHTML code 2. CSS unchangable 3. no need
to make custom php blocks after installation)
1. I would edit box.tpl.php to provide the same html of a WP's
widget, since it is a standard API output. I would override some
themeable functions for the content (ie. theme_item_list) accordingly.
2. Because of the WP-theme engine realy limited, VERY VERY often WP
designers hardcodes something in the page, usually "meta"
informations, categories listing and recent blog posts. You can
imagine that these hardcoded menus could have infinite HTML code.
This means i cannot use a block model again (I already used it to
make the "frame" of widgets).
Even because i want a smooth migration, i decided (for now) to
hardcode too and i coded a bounce of phptemplate_wpsomething() in my
template.php page to keep my .tpl.php pages clear.
*** THE PROBLEM ***
My template.php is full of overridden functions that are not part of
For example. To have a recent blog posts (very common in many WP
themes) i had to override the blog module's hook function blog_block
because it makes a call to node_title_list() (NOT themeable). And
node_title_list() makes a call to theme_item_list that i ALREADY
overriden to make code for the widget-blocks!
So since node_title_list is not themeable (and it wouldn't be wise to
override even if it was) i had to copy-paste the entire hook function
in template.php just to make the code for node_title_list inline and,
finally, be able to change the call from theme_item_list to
1. It breaks the presentation layer
2. It is a stupid mess
3. It is very annoying if u have to override lot of functions (WP API
is limited but not so limited!)
Since I would like to think about an automatic way to convert themes
from WP format to Drupal's, I prefer to resolve this issue before
proceding. Any idea? :)
PS sorry if my following questions will be stupid or full of grammar
errors. I'm a newbie in development and my english is not so great :/
