Drupal: How to add another recipient in personal user contact form

Drupal's core contact module comes with the feature that allows users to have their own personal contact forms. We were asked to provide a way so that User 1 would receive a copy of any message exchanged between users via the forms. Our first thought was to use Rules, but it seemed that creating an event for contact form submission was the long way to go. The solution was quite simple: Using hook_mail_alter.

Reset drupal statistics - The Read counter

Here is a quick and easy way to reset the drupal statistics stored in the database with a couple of SQL queries. You can reset the Total counters with:


UPDATE `node_counter` set `totalcount` = 0;

And the day counters with:


UPDATE `node_counter` set `daycount` = 0;

Translate <Any> in Views Exposed Filter

While trying to translate the <Any> string in Views, locale returned the error "unsupported HTML".

A quick workaround is to switch from <Any> to -Any-; There is an option available under the Views Tools tab just for that.

The string "-Any-" is translatable, so from this point on it is easy to search for the string "-Any-" in locale search. If it is not found, you would probably need to check that you typed Any in the search form (case sensitive!).

Once found, it is easy to enter the required translation.

Draw circle overlay in all points in gmap from Radius in a CCK field | Dynamic gmap Macro in Views

Lately I needed to add a circle in every marker in a gmap provided by Views. So in order to achieve this, I filled in the Macro textarea of the Style:Gmap settings of the View with the following code. But first, I added the field that contains the Radius value and excluded it from Display, to make the value available in the view result set. This value was in miles, so I made the conversion from km as well.
