PHP/Drupal

The article here (http://icant.co.uk/ie6-amelie/) describes its mission as '[It] is time to get rid of Internet Explorer 6 by making it uncomfortable for the end users and blaming something else. To this end we take an IE filter that was made to confuse users — the MotionBlur filter — and apply it randomly to the document.'

I thought this was awesome, so I turned it into a Drupal module that you can enable on your site to lead IE6 users down the long, slow rabbit hole of complete insanity.

Find it here, and enjoy! Your IE6 users definitely won't... and that's the point! http://drupal.org/project/amelie

Miss Katherine Lynch mentioned her desire to host the logs from the Drupal accessibility channel for the a11y peeps and I couldn't pass the opportunity to do something (albeit little) for the community!

So, they're located here: http://log.therealcha0s.net/drupal-accessibility.log

Enjoi!

If you've ever done any UI coding in Drupal with some elements that need to be arranged in a given order, then this snippet is for you!

Drupal provides us the function element_sort, which sorts an array's elements based on their '#weight' elements. This is fine, but unfortunately '#element' is a Drupal idiom, and even within Drupal we find places where we'd rather sort by 'weight' than by '#weight'.

So we have a problem that fits a well-defined pattern, but is too clunky to solve by writing a million functions for each element (what if you want to sort by '#list_order'?)

What do we do? Generate functions at run-time and cache them, of course!

function array_comp_sort_by($element) {
  static $cache = array();
  
  if (array_key_exists($element, $cache)) return $cache[$element];
  
  $element = "'" . $element . "'";
  return $cache[$element] = create_function('$l, $r', '
    $lw = (is_array($l) && isset($l[' . $element . '])) ? $l[' . $element . '] : 0;
    $rw = (is_array($r) && isset($r[' . $element . '])) ? $r[' . $element . '] : 0;
    
    if ($lw == $rw) return 0;
    
    return $lw < $rw ? -1 : 1;
  ');
}

Hope this saves you not only the minute it takes to write a new function every time, but the mental anguish of knowing there's a pattern there, but having to settle and copy-paste the sort function. ^^

An example of this in use:

    /** Sort them by weight. */
    uasort($modifiers, array_comp_sort_by('weight'));
