Thêm 1 block region vào theme trong Drupal 7

In this tutorial, I will walk through the steps for adding a region to Drupal's Bartik theme. There are a couple ways you can do this.

1. Modify the Bartik theme directly. Of course, this is not the suggested practice. In the Drupal community, we don't modify Drupal's core unless we are applying a patch.
2. Copy the Bartik theme to the /sites/all/themes directory, rename the theme, and modify it to include the region you desire.

There is a third option, which includes turning Bartik into a base theme and then creating a sub-theme, but that conversation is outside the scope of this tutorial.

In this tutorial, we will make a copy of Bartik and modify it.

Step 1. Copy the Bartik theme

Step 2. Modify the bartik.info file

Step 3. Add the region to the page template.

Step 4. Upload mybartik to your site

Step 5. Enable your theme and see the new region

Summary

The example above is simple, yes, but it conveys the steps needed to add a region to an existing theme. You can follow this process for any Drupal 7 theme. However, if you choose to copy and then modify an existing theme and that theme is updated, those updates will not automatically post to your version of the theme. If you choose to simple modify the theme so that updates can be applied, then you will likely loose the modifications you made.

At the start of this tutorial, I mentioned the base/sub-theme strategy. This strategy leaves the chosen theme in tact except for a minor modification to the .info file, allowing you to easily update the theme and not loose the changes you have made because the changes are stored in a sub-theme.
