Browser FAIL: "Unsupported form of compression" related to PHP notice

One of my sites had a funny error complaining about an "unsupported form of compression" shortly after installing a new module. The browser would return a white screen of death with an error message (Safari and Firefox).

Content Encoding Error
The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Showcase a User's Comments with Views and Menu Tabs

By now, you should know and love the Tracker module that comes with core. It has its strengths, but many weaknesses. For one, you can't separate out posts from comments, or sort the list in interesting ways. Views can help you make exactly the list you want, and place it in a tab on the user's profile exactly like the "Track" tab.

For this example, you'll be adding a list of comments. Creating the view is simple enough:

  1. Clone the default view comments_recent, and call it comments_by_user
  2. On the Page display, add a Relationship for Comment:User

Adding photos to an event page with Views Attach

There are often 17 ways to do any particular action with Drupal - here is #18 on the list of "How do I display related content on this node's page?" You'll be using the Views Attach module and a nodereference field.

In this example, you want to relate a photo to an event. Inside the photo's content type, create a nodereference field that is able to reference the event content type. When a user is adding a new photo, she will be able to choose the related event if applicable.

Deciding Which is the Best Module to Use

There's a lot of times when you're building a site and trying to figure out the best way to do something. It doesn't matter if you're a newbie or a rockstar, if you're not familiar with a particular type of funcationality, you're going to need to do some homework to figure out the best solution.

One handy way of figuring out the best solution is by gathering up all the possible modules and comparing them. Unfortunately, this can be quick time-consuming. Luckily, there's an entire Drupal group devoted to exactly this!

Theming Submit Buttons

Need an fast way to theme a submit button on your site? Using one hook_form_alter() function and some simple CSS, it's fairly easy to do.

The method below actually keeps the text of the button as text and not part of the image (this allows you to reuse the button image for multiple buttons), but you can just as easily set the #value attribute to '' to get rid of the text.

You'll use hook_form_alter() to simply add a CSS class to the button you want to theme and to modify the text of the button.

Keep Local Database and Filesystem Settings in a Site-specific settings.php

A common development practice is to keep a local web server running on your laptop, or a development/staging server. A feature of Drupal designed for multisite installations can actually help you out in this situation.

Different servers often mean different databases, database users, and passwords. Sometimes, you may also need to point to a different files/ directory or tmp/ directory, especially if you are moving between Windows to Linux, or a local machine to a server.

Rounded Corners for All (Except IE)

Getting quick and easy control of rounded corners is a bit of a holy grail for theme developers and CSS jockeys. In order to do rounded corners correctly and have them appear consistent across a wide range of browsers often entails several additional HTML elements (usually DIVs) and several hours of CSS head-banging.

An easy way to get around this, providing you're willing to give up rounded corners in IE (a big "if", I know) is to utilize a couple of browser-specific CSS properties. Both Firefox and Safari utilize the "border-radius" CSS properties. For example:


Using Context Module to Set Body Classes

The Context module is a great way to get a site's unwieldy block configuration page under control. It allows you to display individual blocks only when a certain "context" is available.

For example, a context may be set when a particular view is displayed. When that happens, you can use the Context module to display certain blocks alongside the view. If you find yourself writing block visibility code over-and-over again, the context module will save you time and headaches.
