How can I delete all nodes of a given content type in Drupal?

If deleting nodes of content is the requirement on your Drupal website, I will help you to accomplish the job. By usin the web interface, you can delete up to 50 entries at once. If deletion of a larger amount of entries is the requirement, you can check the Bulk Delete Module.

The Bulk Delete Module uses the Batch API to accomplish the deletion job to bypass time out or memory issues when deleting a huge number of nodes with a single call to node_delete_multiple().

The Bulk Delete Module deletes any nodes of a certain node-type using the Batch API. The most important thing to note in this module is that nodes once deleted will never be recovered. Means, they will be permanently deleted. So, be careful while opting this module. 

Before moving to deleting nodes, we must familiarize ourselves with Drupal, its use and disadvantages you are likely to encounter while deleting nodes. The procedure to delete nodes is more or less the same with version, though some recent version feature Drupal delete all content function, which is not going to make any difference here.

What is Drupal?


Drupal is an open-source, free web CMF (content management framework) written using PHP but distributed freely under the General Public License, also called the GNU. 

Drupal is a back-end framework, currently being used by not less than 2.3% websites in the world. It is used by websites of all sorts - blogs, corporate, government agencies, freelancers, and also amateur programmers.

The drupal community is also equally big and there are enough contributors to keep the project going for several years from now. From data collected till December last year, Drupal's community was believed to have a whopping 1.39 million members.

Out of the million contributors, 117,000 were believed to be those who were actively contributing, with modules as many as 44,000 in number (customization functionality is available with every module). There are over 2800 free themes to change the way your Drupal looks.

About Drupal Nodes Delete Functionality


Contents on a website created using Drupal is stored not as contents but as "nodes". In other words, whatever contents you upload at one time is one node. If you load 7 pages at once, then there will be 7 nodes for each page. In simple terms, any individual content uploaded is a node. Nodes can comprise of blog content, poll, forum topic, etc.

Greater the number of nodes, the more flexible is the web platform. Thus, creating several such nodes help website have more flexibility, allowing you to add new features without undergoing troubles.

A node module is used to manage these nodes. Using this module, you can -

- List, sort, manage site contents.
- Set how all posts will be displayed by default.
- Configure the "content types" and create new ones.

By now, we have learnt about Drupal and how you can add or delete Drupal nodes. It is about time we learnt some of its benefits and demerits.

Flexibility


One of the compelling things with Drupal is that it is able to create and manage a wide variety of content, which might include videos, polls, blogs, and even statistics. Because of this, Drupal enables an extremely flexible design that helps you create website rich in not only content but also performance.

Scripts run in Drupal has capabilities of design elements editing, making it easy to create complicated web pages as easily as simple web pages. It also allows you to adjust and modify & implement endless possibilities into your site.

Scalability


Another major benefit of using Drupal is that it's extremely scalable. You can grow the number of your web pages without changing anything underlying the website. It is because of this reason that Drupal accommodates content growth so well. It can also be scaled between period where there is little traffic to periods where there is enormous traffic on the website.

Disadvantage

There are not many downsides with Drupal, provided you are using it correctly and for the right purpose.

- It has advanced interface, with Professional construction that make Drupal difficult to learn. The interface is not at all intuitive.
- High system requirements. Before turning towards Drupal, you must be prepared to pay expensive hosting fees.
- High-quality designs are lacking in free access modules. Most users are engaged in self-development designs for their projects, leading to dearth of quality topics for the site design.
- The modules are difficult to update and program. Web developers who previously dealt with easy and simple CMS will have difficulty coping up with commands in Drupal.
