Responsive sites and adaptive sites are the same in the sense that they both change appearance based on the browser environment they are being viewed on. One of the major challenges in creating a web design is how to create one that has lasting value, at least for a planned period of time. It is more likely that a first time visitor/customer may not be familiar with your products or services. There are other possibilities that your visitor is in a real hurry, or they’re on an iPad, at a coffee shop. Or maybe they’re on some device for which a website hasn’t been planned yet.

Moving to Drupal 8 deserves careful consideration in the technical front,especially when it comes to migrating from an almost stable platform like Drupal 7. Having said that, considering the advantages of Drupal 8, it will likely be the best solution for your business.

For a client who owns an active Drupal 6 website, Drupal 8 promises a whole lot of opportunities. Although we know that Drupal 6 can cater to everything that is needed to create a platform that fits our requirement, Drupal 8 offers the extra edge which allows us to build something faster and more stable. And this is the key for any modernized platform. In this respect, it is likely that Drupal 8 provides a much easier transition to a great working site. Advantages for Webmasters:

As we all know, the official support from Drupal.org for Drupal 6 is going to cease and the security updates will no longer be available. However, there is no reason to get upset; in fact, there is nothing in the code that will cause Drupal 6 site to stop functioning after February 24th, 2016. If you choose to keep running the code, it will run as long as your hosting company allows to do so. Then, why would anybody want their website to be migrated to Drupal 8 ? The answer is quite simple, nobody wants to stay behind. It's actually a step forward.

Before we discuss on how to to join multiple database tables using db_select in Drupal 7, let me tell you that we can add as many joins as we want and most methods such as, 'fields', 'conditions', joins etc. can be called multiple times. However, one thing may be worth mentioning is that the call to join() needs to be separate. It should not be "chained", meaning that one should use this,

In order to add a new theme template file (.tpl.php file), we need to implement hook_theme() in our Drupal 7 module. A theme template need to be specified in the hook_theme() function. They produce HTML and renders Drupal render array elements to the screen.

In Drupal 7, when we do customizations we would want the custom module to create content in the form of a render array. We know that a page callback should return a render array which allows the custom module to handle the content as long as possible in the page generation process. Sometimes, wrapping two render array elements together could be an easy way out while dealing with render array manipulations. Here is how we can achieve that.

Drupal offers a variety of ways to implement solutions when it comes to custom theming and it has been abused often due to the very same reason. Choosing the right way is what Drupal developers find tricky. If it is not done right, it is quite likely that you 'Awesome Drupal Website' would turn into a code-monster soon. This can even make maintenance difficult. Hope this 'tiny bit of' information could help you through it.

In Drupal 7, a theme function is a PHP function that is used to wrap the output variables with HTML. For adding a theme function in our custom Drupal 7 module, we need to implement hook_theme(). A theme function is prefixed with 'theme_'. However, they can't override existing theme functions. Such functions are invoked using theme() rather than being directly called. Also, they are faster compared to the template (.tpl) file implementations.

The purpose of implementing hook_theme either in a custom module or theme is to register it's theme implementations which specify how a particular render array is to be rendered as HTML.
