Command line Drupal install and update script for multi-site hosting

Maintaining a Drupal site, or a collection of sites is much easier if everything is kept completely separate--Drupal core, contributed modules, and the site itself.
This is even more important if multiple sites are hosted on the same server. Drupal's own multi-site support can be a nightmare to maintain, believe me! (e.g. when you want to upgrade modules or core).
A must simpler and easily supported configuration is to keep everything separate and to use symbolic links to tie it all together. For example, I keep:

Installing Compass on Drupal server

Installing the theme is the easy bit. What is much harder is setting up automatic SCSS recompilation.

  • The README.txt file suggests using a full-blown installation of node.js just to manage this.
  • A much more lightweight solution is to use compass

updating webform from 2.x to 3.x

Theming CCK fields in Drupal 7

Drupal node display can be overridden using a template file of the form:

  • node--content_name.tpl.php

The simplest way of displaying fields is to use the render() function

The render array is documented here: drupal.org/node/930760

  • Individual field values can be found in one of:
    • render($content['field_name'] fully rendered value
    • $content['field_name']['#items']['0']['safe_value'] will include paragraph markup
    • $content['field_name']['#items']['0']['value'] raw
    • $content['field_na

Drupal 6 to 7 upgrades

The Select builder adds a LOT of overhead. You should not use it unless you need one of the things it offers: Dynamic query structure, hook_query_alter, certain db-unportable features that don’t have a simpler version (random ordering, for instance), etc.
For the run of the mill SQL query, db_query() is several times faster than db_select(). If you need a limit query, db_query_range() is still there.

The "Support" module on Drupal

Some notes on configuring the module

  • Follow the online instructions, but also
    • set the support content type not to be on the front page
    • set the from email address to be do-not-reply@mydomain
    • Default sort: State/ascending
    • Secondary sort: Last update/descending
    • Modify the new and updated ticket email to be something like this:

Deleting large numbers of comments from Drupal

  • You can easily delete all comments with:
DELETE FROM comments;
  • The problem comes when there are good and bad comments, and you only want to get the bad comments. -The cleanest way is to delete all the rogue users first. That will set the UID on their comments to 0, so you can delete all their comments by running:
DELETE FROM comments WHERE uid=0;
