This will just be a small article and quite a specific one. We’ll be looking at how to verify an input to guarantee it is a valid 8 figure grid reference. This will be checking against the UK Ordnance Survey standard, so two letters followed by four easting numbers and four northing numbers. e.g. AA11112222 It is important to remove any spaces from the string before submitting. This can be achieved through a small JS function and a .replace function. … Continued
If you’re used to writing your own PHP applications, you will no doubt be used to having to deal with exceptions being thrown at awkward moments. Resulting in a ugly 500 error being shown to the user and no extra direct from them to take. Luckily we can choose our own way of handling these exceptions, showing a better message or logging the error more efficiently. In an ideal world, we wouldn’t need these as everything would work perfectly, all … Continued
The contents of this article has been replaced by a PHP Composer package, hope you find it useful. View on Github This article is specifically about directly uploading files to S3 using the AWS Signature Version 4, which is mandatory for new S3 regions, like Frankfurt (EU). It will also become required on other regions at some point as Amazon migrate over, so it’s recommended to use this method where ever possible. For more info, you can read about … Continued
With a PHP project we have just started, we decided to begin development with the Laravel 5 framework – even before it’s been released. The framework is due to be released this month (Jan 2015) and instead of starting with Laravel 4 and attempting to migrate upwards, it seems natural to begin with the newest version even though it’s features might change slightly pre-release. Being comfortable developing with both PHP and Laravel 4, some of the changes with version 5 … Continued
Web components, sometimes mixed up with the Shadow DOM, are now available in Firefox v29+ under this flag – but they won’t be available to the average end-user. How to Enable: In your address bar, go to: about:config Search for the property: dom.webcomponents.enabled and mark it as true. If your already on a development page, remember to reload it.

Over the Christmas period I had a play around with getting PHP to run code asynchronously (not as easy as it sounds). When you have code, like API calls, which take anywhere near to a second to complete it drastically adds to the loading times of your pages. One easy solution for web apps is to only call the back-end PHP using AJAX. This means the page doesn’t hang and reload, things can happen concurrently and quickly. This solution isn’t … Continued
In the early days of PHP, if you wanted to store passwords you had to do a lot of the work yourself – this left many systems vunerable, as it was only half implemented or done badly. Since then, however, the team behind developing PHP has been hard at work making the whole process much easier (thus increasing overall security).
While working on a project recently, a dynamically loaded section was needed. It was used in a transition between step one and two in the user’s journey, after an API call had been made. The user was allowed to go back to step one at any time, resulting in a new API call – which was to be expected – but the call to get the HTML for step two was also made again. The same HTML which had just … Continued
First there was Oceanic, then Waves and now it’s Sandcastle. Designed by a Turtle now has a new look after another year of active development. (Hopefully the name and images can remind us of the sunny times). The New Design The new design supports an edgy-look, sharp edges and bright colours and hopefully brings what’s important most (the content) to life. Technically Front-end development for this theme used Grunt and Bower for the first time to help manage third-party CSS … Continued
If you’ve worked with any large file in PHP you will probably have come across a large block of include statements at the top of it. Includes allow one file to include many other files and are used a lot in OOP. A large amount of includes at the top your code poses two major annoyances: firstly they’re taking up valuable space which could otherwise be used for more important things; secondly because of their explicit nature, they get left … Continued
Flexbox & History One of the best ways to achieve a row of boxes which match in their heights is with an up-and-coming feature called flexbox. This is particularly important when presenting dynamic content, if you’re using pre-selected, static content then often the best approach to take is just to add a min-height within the CSS for the columns. As soon as the content extends a min-height however they will escape and have differing heights.
Most of us will know how HTML forms work: inputs contained within the form send data to a url, by either a GET or POST request. This will result in the server being able to access this data on the other end. The way to do this usually goes something like this:
