WYSIWYG (a.k.a HTML Editor) has become a De facto for quickly formatting and publishing contents from dynamic site like Drupal. This is certainly a time saver and prevents from getting hands dirty with HTML.
In this connection, CKEditor has been a pioneer and around in use and development cycle for a decade (first release was on March 2003, in the name FCKeditor).
Simplenews is one of the solid Newsletter management modules for Drupal. It allows a Drupal site to have multiple newsletters at once, nodes can be sent out as newsletter to multiple recipients on a single cron run. It plays well with HTML emails as well with Editors like WYSIWYG, Drupal mail system and other contrib modules like Mime Mail. Besides these, it allows to have specific sender name and email address per newsletter.
Drupal 7 uses InnoDB as default MySQL engine for all tables in database. Innodb is a better option for processing large volume of data. It gives good support for ACID property, however there are some cases where the InnoDB falls short of ones expectation. Some common examples includes count queries, memory use of Innodb,etc., see here to know more.
It is apparent that we modify any form in drupal by implementing hook_form_alter(). But there are cases when even the hook_form_alter() cannot offer a solution in altering the form fields. I recently faced such a situation, when I was trying to empty the labels in the password & confirm password fields in the user registeration form in Drupal 7.
No Drupal Developer needs introduction about Drush. The power and features of Drush has made the job easier for many developers. Drush by default has a list of commands that we can make use of, the entire list can be seen here. But apart from that, the Drush does has the feature to allow custom commands.
Creating Vertical tabs in Drupal 7 forms is an easy task, but to accommodate the design needs we at times have to use different style. For instance, horizontal tab might be needed. The same makes more sense for shopping cart check out like pages. And here the need for looking solutions outside the Drupal core arises as horizontal tabs are not readily available in core.
It is no surprise that production sites at times may work differently from dev / stage due to various factors. And in such circumstances, there is a need to login as real site user to be able to reproduce the issue. Of course it is not easy to fix a bug unless it is really reproduced by developer.
In one of my recent works, I found a simple trick using Drush to get access to real user account without distrubing his/her account credentials like login name, email, password, or similar.
Downloading PDF from a site has almost become a fashion to share some contents related to the site. This information can be a e-book, certificate, catalog, letter and the guess goes on. But one of my recent projects had the feature of allowing user(only authorized users) to download a certificate.
