By default in drupal if we click on any taxonomy term, it will execute the taxonomy/term/% menu. We can change this default taxonomy/term/% menu path to a custom menu path. In one of my project I had a requirement to execute a custom function for my vocabulary in stead of executing the taxonomy/term/% menu and I had found a solution for this. The following are the steps to be done.

The following is the shell script that will shutdown all computers in the network. This script will be really help full for system administrators who need not want to check all systems, whether all the systems in the office has been shutdown properly when the employees leave the office. The script will check all the active ips in the network and write the those ips to a file. It also login to each system and execute the shutdown command. The things that are to be done before running the script is to 'Make sure your public-key has been added in the authorized_keys file in .ssh folder of root'. This allows the script to login to each system by the method of public-key authentication rather than prompting for password. And also the 'StrictHostKeyChecking no' will avoid all prompts during ssh.

As you know that it is not easy to check manually the broken links in a website. Suppose if the site contains thousands of web pages and the pages keeps on getting added or deleted at the same time. In this situation it is impossible to manually test the broken links in a site. So in this case you need a tool to do this job. 'Xenu's Link Sleuth' free application helps you to check all links on web pages for errors. The application will shows which links are broken and which are active. So here I am explaining how to test broken links in a website by this application.

Suppose your drupal projects contains products to sell. And you can use coupon code while purchasing products. For using coupon code in your druapl site, Ubercart Coupon code module may be installed. Please check the below cases which contains the test cases of checking coupon code functionality.

Suppose you have to take the print out of a web page while working in a project.Some times the whole content in the page will not be printed as the contents at the end of the margin are cut off or the images are not displayed properly. Alignment issues and padding issues may also appear in print pages.So the user should be careful while taking the print out of a web page.

Suppose your Drupal project handles products which can be purchased through online and you are using Ubercart 'taxes' module to handle tax rates which are applicable to your product. Also Admin has the permission to add tax rates and conditions. And a registered user can buy the product. Here I am going to explain some of the test cases which you have to execute while testing this functionality. The cases you have to test are:

Use case lists the steps involved in the interaction between the actor and the system. Here actor refers to the users who are interacting with the system. The main objective of the use case is to co-ordinate the functional requirement, user roles and basic flow of actions into a single document. Like SRS, 'use case' template is prepared at the beginning of the SDLC. The use cases are often prepared by the Business Analysts. The main difference between use case and test case is that, use case focuses on the requirement of the site (business requirement) while test cases include different scenarios (positive and negative) for ensuring the correctness of the application. Use case can be used as a reference for writing test cases, for getting a basic work flow of the site. Since use cases focuses on the customer requirement, the document plays an important role in ensuring the quality of the product. Here is a use case template, you can refer while preparing Use cases for your projects.

In this article I will be explaining a task I did for one of our sites in Drupal6. In this site, for every content type say event the users manually entered year along with the title in title field. So my task was to remove the year from title and save it in a seperate cck field.

Have you ever seen your face? Not in a mirror, but with your own eyes? You may have seen other parts of your body, but never your face. When you think about it, there are so many things that are not humanly possible. That is why we need machines. Simply put, technology should aid in human development. But as any other thing, if technology is misused, it becomes a curse. The collective effort of mankind may never be able to find ideal solutions to technological challenges, as done by a state ­of­ the art A.I Quantum computer. This sets the stage for Artificial intelligence.

In order to identify what to write on in this edition of the newsletter, I interacted with some people in Zyxware. The suggestions, at first glance, appeared varied. But the more I think about it, the more I feel that there is a common thread running through them. The common thread is that of the future of Zyxware as an organisation, its vision and how it plans to get there. I am putting together a response here which are broad answers to the questions. More specificity would require me to take up more space which I am afraid will not be possible in the newsletter. But I would be happy to engage in the comments section.

Webform is a helpful module that enables you to submit information such as contact forms, surveys etc. It is easy to configure webform in a drupal site. Now, what about displaying a webform inside a colorbox? Although it is easy to install colorbox module and write custom code to display webform, we also have to effectively handle form submission and validation errors. However, there is an easy way in drupal7 to display a webform inside a colorbox.
