A blog about web development and Drupal.
Although not typical, it is an occasional necessity to store sensitive data in a website in such a way that it is reasonably well protected from prying eyes. On a recent project, we needed to implement a method for content editors to encrypt some parts of the nodes' content.
Views is an essential part of any Drupal site. It is very versatile and allows non-developers to set up all kinds of listings of their content. However, no matter how versatile it is, you will always find a scenario that is not feasible to set up on its user interface. But if you are a developer, you have even more ways of manipulating views. Making one field conditional on another field One not so uncommon scenario is where you would like to make the display of one field conditional on some other field. Let's suppose you have a listing of recent content. The listing shows the content type,…
When setting up content types on a more involved site, a developer could easily end up with having an enormous list of fields in one single content type. When this happens, I tend to pause for a second, and think through whether there is any way to consolidate that list. Chances are, I find a field or two whose values either depend on other fields or can be generated without user input. These are the exact scenarios where the Computed Field module can be a great choice. Computed Fields lets you define an algorithm to calculate the value of a certain field, freeing the end user from having to…
Although the CCK3 module had never seen a full release, it was still worth upgrading Drupal 6 sites from CCK2 to CCK3, because the latter added a very compelling tool to CCK's arsenal: Multigroups. This feature allowed users to group several fields together, and enter multiple values into that set of fields as a whole by repeating the field group whenever a new value is added. For instance, let's suppose your node has an event multigroup containing date and location data. If you were to add a new value to this multigroup, a new set of date and location fields would appear, and you could enter…
