Tips and Tricks for Improved Drupal Security

Drupal is one of the most popular free and open source web application frameworks. Drupal is almost infinitely extensible through not only various theme possibilities but also the vast library of modules or add-ons. However, this great extensibility is also a point of weakness should insecure or vulnerable code be used in either themes or community contributed modules that can result in compromise. The following guide on best practices for Drupal covers main areas of attention in regards to security for any Drupal web administrator.

Intercepting mouse events on an iPad

In the last post we saw how we could easily work with mouse events on an iPad. Touchscreen devices like the iPad do not have a cursor, so the user cannot exactly move the mouse over an HTML element triggering a ‘mouseover’ event. One of the readers requested on how we could use a different interaction pattern on an iPad for a ‘mouseover’ event than on a desktop browser. For example in the following web page code the image-container class is attached to images div which displays a preview link overlay on mouseover.

Making ‘mouseover’ event work on an iPad

Because of the way Safari on iOS creates events to emulate a mouse, some of your web page elements may not behave as expected on iOS. In particular, some elements that only use mouseover handlers need to be changed because iOS doesn’t recognize them as clickable elements, such as the div below. As the image-container div is not clickable in iOS, the corresponding mouseover event is not fired.

Efficiently Replicating RETS data to MySQL

A recent project of mine entailed replicating a RETS database on a local MySQL database server. The client had a new real-estate mobile search app in development and wanted to have a local copy of the RETS database for search queries instead of a remote RETS server. This approach has several advantages:

  • Response times for accessing your local database are significantly faster than connecting to a remote RETS server for each request.
  • RETS servers requires that you query using certain combination of fields and also limits the number of fields you can search on. Using a local database would allow you to search on any field with any combination.
  • RETS servers also limit the time of day you’re allowed to access the RETS server and also restricts how much queries you can run per hour. You may also be limited to the number of records you can retrieve per query from a RETS server while a local database wouldn’t have that limit.
