Drupal 7

As compared to Drupal 6, using Drupal 7 you can no longer rely on $() as the jQuery function because it’s simply not recognized. It should be taken into account in order to ensure that there are no conflicts between JavaScript libraries that are possibly used on a site.

Some php generated content, for example, a view or some variable, is often to be inserted in the middle of the node or block.

Transferring configurations of one working site copy to another often can present difficulties. Particularly, date formats are not always correctly transferred with module features.

Oftentimes, possibility of exporting significant amounts of data into CSV file format should be provided.

During deployment there is often the need to create/edit/delete fields. Here are some examples below how this can be done with the help of code.
