Pragmatism in the real world
Now that Zend Framework 1.7 has been released, I thought I'd take a look at the built in file upload element, Zend_Form_Element_File, and see how it can be used. This is how to use it in its most basic form. I decided to use the same set of form elements as before in order to make things easy. Let's start with the form: The form We extend Zend_Form and store it in the application/forms folder… continue reading.
PHPNW 08 took place last Saturday, and even though I wasn't too well, I had a great time. I thought my talk went okay, and judging from the feedback, at least some people learnt something from it which is good. I hope that the tongue-in-cheek references to my book were taken in the light-hearted manner intended. The conference seemed well-attended and the organisation was top-notch. Jeremy, Jenny, Emma, Lorna and everyone else involved did a… continue reading.
Following on from the discussion on Zend Framework Action Helpers, let's talk about hooks within them. Hooks are a feature of action helpers that allow you to automatically run code at certain points in the dispatch cycle. Specifically, there are two hook functions available for action helpers: preDispatch(): runs before the action function is called postDispatch(): runs after the action function has completed These allow you to ensure that some functionality is always run for… continue reading.
When you have some functionality that needs to be shared across multiple controllers, one method is to use action helpers. Action helpers are very powerful and contain hooks to automatically run when you need them too, but you can ignore all that if you don't need it. The first thing you need to do is decide where to put them. The latest default project structure document recommends using a sub folder from your controllers directory.… continue reading.
A question came up on the phpwomen channel today about how to find the path to php executable for use in cron scripts. The answer that came back very quickly to use which or whereis. It turns out that the server in question is a shared host with a control panel for access to cron and ftp to upload your files. A test proved that shell_exec() wasn't going to work too. After discussing it for… continue reading.
From one conference to another one. On the 22nd November 2008, the PHPNW08 conference in Manchester takes place and I'm speaking! My talk is entitled "First steps with Zend Framework" and it will cover an introduction to ZF and then walk through building an MVC application using the Zend Framework. There are lots of interesting talks scheduled so far. They look aimed at a wide and I want to see every one. If you are… continue reading.
I'm now back from ZendCon which was the most intense conference I've ever been too. I arrived late Saturday evening and after dropping off the stuff at my hotel, I walked the mile or so to the conference hotel to meet up with some #phpc people. I didn't stay in the Hyatt as it was too expensive for me. The walk took a little longer than I expected as I kept walking the wrong way,… continue reading.
To uninstall MySQL and completely remove it (including all databases) from your Mac do the following: Use mysqldump to backup your databases to text files! Stop the database server sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* edit /etc/hostconfig and remove the line MYSQLCOM=-YES- rm -rf ~/Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /private/var/db/receipts/*mysql* The last three lines are particularly important as otherwise,… continue reading.
There's a new UK PHP conference coming in November. PHPNW08 will take place on 22nd November 2008 which is a Saturday so there's no excuses not to go! To select the talks that will be presented, a Call for Papers has been announced with a deadline of 21st September 2008. From my reading of the website, this is a developer-centric conference and so if you have something to say about current PHP technologies and development… continue reading.
I'm kind of neglecting this blog at the moment. Sorry. I was away last week and I'm head down into editing Zend Framework in Action. It's amazing how many details the technical proof reader and our copy editor have found. The book is going to be so much better as a result. I need to go through each suggestion though and ensure that the meaning hasn't changed and to implement the suggested technical changes. When… continue reading.
