What Is a Theme Engine Drupal CSS Styling

Wed, 22 Feb 2012 09:15:10 GMT

A theme engine is a collection of scripts and files that serve to interpret the programming language used and process the commands contained therein. As data is drawn from the database and from outside sources if any , the theme engine plugs the data into a predetermined format for display. There are several popular theme engines, each of which is designed to interpret different templating languages. Drupal is distributed with the PHPTemplate engine. PHPTemplate is popular for a variety of...

If you ask anyone who has used Drupal for a while what the killer module is, the answer will likely be Views, Panels, or the Content Construction Kit CCK . Views is usually mentioned first, and it's the module that many users say they can't live without.

Two Contrasting Examples Create Drupal Themes

Sun, 12 Feb 2012 18:01:51 GMT

As you can probably see, PHPTemplate presents a number of options that can be used to support the creation of themes. You can almost literally do as much or as little as you like. A look at the range of techniques used by the themes in the market shows a wide variety of approaches to theming. Some themes, like the Gagarin theme we installed in Chapter 2, take a very elemental approach and implement only the bare minimum. Other themes, like the default theme Garland, are more complex, and...

Bayesian Filter DrupalCommunities

Sat, 11 Feb 2012 14:12:43 GMT

The Bayesian filter learns to detect spam by being shown content that has been identified as spam by the site administrator. The best way to describe this method is to quote Jeremy Andrews, the author of the Spam module. The Bayesian filter does statistical analysis on spam content, learning from spam and non-spam that it sees to determine the likelihood that new content is or is not spam. The filter starts out knowing nothing, and has to be trained every time it makes a mistake. This is done...

A pager looks like this lt lt previous 1,2,3,4,5,6,7 next gt gt . Visitors use the pager to navigate through all of the items. Views automatically creates and displays the appropriate pager based on the number of items that are in the complete list. By default, the Views module renders lists using a pager with 10 items per...

We need to inject the punchline into the node loading process so it's available to other modules and the theme layer. For that you use hook_load . This hook is called just after the core node object has been built, and is only called for the current node type being loaded. If the node type is joke, then joke_load is called.

PHP XTemplate was once the default theme engine in Drupal but has fallen by the wayside as development of the application slowed. For many users, XTemplate was a popular system. It separates the HTML from the PHP and makes it easy for designers to work with themes. Also, as it is written in PHP and can handle either PHP4 or PHP5, it tends to perform well with Drupal. Unfortunately, at this stage, it seems unlikely to be making a comeback in the near future, and those of you who previously...
