Drupal 6

Here is a function that you can pass an imagecache preset name and a drupal image file path to and it will try to build a derivative image from the preset name and return to you the path to the derived image:

Here is how to bulk delete a big chunk of nodes for a particular content type in Drupal. This code snippet was taken from here and modified to set a limit so php won't run out of memory and then it tells you how many nodes are still left for that content type. This is easiest to run inside the Devel's module PHP block.

To theme the exposed filter form on a view in Drupal:

Export Database to File

So today I wanted to learn how to export a Drupal database to a file quickly. Back in the day I would've logged in through cPanel and navigated to PHPMyAdmin, then manually select an export of the database and have to choose where to save the file. Not to mention all the previous steps listed would need to be preceeded by a Drupal cache flush (I don't like the cache inside a database backup). Typically this would've taken me about 5 minutes to complete, well my friends, no longer is that the case.

Drupal 7

I found this solid example for Drupal 7.

Drupal 6

Put this PHP code inside your module, e.g. sites/all/modules/my_module/my_module.module

Drupal 7

$header = array();
$header[] = array("data" => "Column Header Title 1");

$row[] = "Row Column 2 Data";

$rows = array();
$rows[] = $row;

$html = theme('table', array('header' => $header, 'rows' => $rows));

Drupal 6

So the other day I needed to detect when someone clicks on the background image of my drupal zen sub theme. Here is how I did it using jquery:
