I’ve recently started building a new web app and have decided to build it in Symfony (and hopefully ultimately Vue for the front-end), as a way of learning what looks like a really cool framework. I’d had an introduction to Symfony through work, then did some online courses, including a load of the excellent SymfonyCasts, […]

KnockoutJS: multiple jquery actions in one binding handler
5th August, 2016 - Posted by david
A general rule I follow when using KnockoutJS is that there should be no DOM manipulation in the viewModel. The viewModel should be completely independent of any markup, while any changes to the DOM (via jQuery or otherwise) should be handled in the binding handler. This makes your viewModels much more portable and testable. As […]
Autocomplete with KnockoutJS
3rd February, 2016 - Posted by david
Recently I started a new job at a company that is looking to transition away from a customised, unstructured, jQuery module set up to use KnockoutJS and RequireJS for it’s modules. This approach was chosen because the core platform is based on Magento and the forthcoming Megento 2 uses KnockoutJS heavily throughout it’s frontend templates. […]
Deeplink to a sub-page within a Facebook iframe app
24th May, 2015 - Posted by david
Facebook have long had the ability for developers to write custom apps and embed them as tabs in people’s or company’s Facebook profile pages. What I’m talking about here is when you write your own HTML app and host it at e.g. https://fb.mysite.com, which is then embedded into profile pages via an iframe. These apps […]
How to call some Pixastic functions
21st February, 2015 - Posted by david
I was doing a bit of work with Canvas recently, manipulating images in the browser and writing the results out to files. I was looking for a package that could do various effects on the images, such as sharpen, blur etc. and came across the Pixastic package used in similar applications. However, unfortunately, the website […]
Homepage takeover with existing skyscraper ads
14th February, 2015 - Posted by david
UPDATE: Originally I was using Javascript to position the 2 banner divs along the main content, but have since figured out how to do this with just CSS alone. I’ve left the article as it was for posterity; there should be enough here to still figure out what you need to do! Anyways, to achieve […]
Opening hours done right, in PHP and MySQL
7th February, 2015 - Posted by david
I often see different ways of storing and displaying opening hours for various businesses when browsing the web. Some seem to simply store them as an unstructured blob of plaintext and spit that back to the user. Others will store the exact times for each day and display all 7 days on 7 separate rows. […]
Backbone JS Models and Collections in same file with RequireJS
31st January, 2015 - Posted by david
In BackboneJS, classes/objects are called Models and groups of these models go into Collections. Using RequireJS, you define something and return that something for use in other files. In many BackboneJS examples, I’ve seen say a Person Model and a Person Collection stored in separate files, with each one being imported separately to the script […]
Extending Google Maps class with RequireJS and Underscore
24th January, 2015 - Posted by david
I’ve been working alot with RequireJS lately and love the whole modular JS movement, where blocks of code are safely contained within separate functions, that can be loaded in when necessary, without worrying about variable/function name clashes. Generally each module is stored in it’s own file but you can combine several modules into one giant […]
Memcache variable breakdown
30th April, 2014 - Posted by david
At work we use memcache as our local variable cache and the excellent memcache.php from Harun Yayli to give us a simple way of viewing what’s in the cache. One use case we came up with that was missing from the original memcached.php script was a way to group similar variables and see how much […]
