After using Drupal's template.php file to preprocess html and add unique classes to various html elements, I because very dependent on page specific css classes. While building a Ruby on Rails app, I thought it would be nice to at least add in a page-specific body class. Here's a quick snippet you can use:

<% page = request.request_uri.gsub(/^(\/)?/, '') page = page.gsub(/\//, '-') %> ">

This will:

Content migration is a pain, particularly when you are charged with copying content from an old html site into a new framework. Often times, old content comes with the baggage of inline css styling, which wreaks havoc on your pretty new site design. Here's a handful of helpful regexs that I use to strip out undeed inline styling, while still preserving the html element structure.

To strip out span tags: <span[^>]+> Follow up to strip out the close tags:

Strip out inline styling: style="[^"]+"

I once had the misfortune of developing a Joomla site with three separate templates, each of which contained four separate color schemes. The color scheme needed to be selected based on the content's section and/or category.

This PHP script will cycle through various methods for determining category id, section id, or content id. It also includes an array for manually setting the stylesheet by id.

If you'd like to apply a rule only at certain URL paths, add this php condition:

<?php $url = drupal_get_path_alias($_GET['q']); $needle = array( 'search_pages', // 'another-url', ); foreach ($needle as $url_needle){ if (strstr($url, $url_needle)){ return TRUE; } } return FALSE; ?>

UPDATE

Looks like this module may also be helpful:
Path Rules

I often us the Rules module to redirect a user to the login page when they try to access protect content. Unfortunately, Rules' "page redirect" action doesn't preserve the destination parament, i.e., the node that the user was trying to view. Adding a small bit of php code to the redirect url fixes this issue:

To: user/login ? <?php destination=node/[node:nid] ?>

Goal: create link that goes to a new page and opens a specific accordion drawer.

Using the Views Accordion module in combination with a little custom code accomplished this. Here's a step by step guide.

Create your view

-add this header with input filter "php code":

If you'd like to make a menu item open in a lightbox, you can use the Lightbox2 module in tandem with the Menu Attributes module module to achieve a variety of effects.

Download and enable the Menu Attributes module.

This will let you add a rel attribute to any menu item. Add "lightframe" or one of the following rel values (as appropriate):

Often times, you may want to customize the appearance of a views field, or perhaps add a bit of logic to the output. You can customize the display of any field in Views by utilizing the Views Customfield module.

Here's an example of how to breakdown a basic cck fieldfield into its constituent parts.
