When Mike Bell approached me several months ago and said we should do a Drupal camp in the north west I was completely on board with the idea. So for the past few months I have been working with Mike and a group of people from the North West Drupal User Group (NWDUG) to create such an event. The result was DrupalCampNW2012, which was held from Friday 23rd to Sunday 25th November. The venue was the new University of Salford campus buildings in MediaCityUK.
I recently saw an implementation of a Twitter wall that used node.js to run searches on Twitter and post the results on a webpage. I had been wanting to create something using ReactPHP so I thought this was a good opportunity to have a go. ReactPHP, if you haven't heard of it, is an event-driven, non-blocking I/O that is essentially the PHP equivalent of node.js. The major difference is that ReactPHP is written in pure PHP with no extra components, whereas node.js is a collection of different programs, interfaces and languages.
I spent what seemed like an eternity today trying to figure out something in a form I was creating on a Drupal site. I was building a multi step form with previous and next buttons, both of which were submit elements like this.
Adding an alias to your system is a good way of saving time when remembering complex commands. You can reduce a command down to a quick two letter command that is easy to remember.
The alias command can be used to assign an alias on the fly. You can create an alias to 'ls -lah' by typing in the following into the command line.
alias ll="ls -lah"
Now, when you type 'll' you will actually run the command 'ls -la'.
Running a simple syntax check over your files is a good way to save time. This can be when testing code but best practice is to not to even commit code that contains syntax errors.
You can syntax check a single file using the -l (lowercase L) flag with the PHP executable like this.
Following on from the PHP script to print happy birthday I wanted do the same in a bash script. I don't really use bash for much more than stringing together commands so I had to figure out how to do loops and if statements using the simple bash syntax. I also wanted to pass the name of the person as an argument, rather than hard code it into the script. This is what I came up with.
