  1. Helpful tools and websites for designers and developers

    Leave a Comment

    So what do I use? Here goes…

    The Web Design Forum

    Get helpful advice from a solid community, a mixture of seniors and juniors. Post up whatever problems you’re having and you’ll get a helpful response. Also a good way to network with other developers and designers, and networking can be hugely beneficial.


    CSS Tricks

    Infamous CSS and HTML blog run by guru Chris Coyier. Coyier is one of the most well known authorities in the area, so he’s a very important person to be following.



    Tutorialzine is run by the immensely talented and respected developer Martin Angelov, and covers a wide range of topics. His tutorials are occasional but always of the absolute highest quality, and he helps instil excellent coding practise.


    Paul Irish

    Paul is another important person to follow. Irish works for Google on the Chrome developer relations team, and a lot of his posts are insights into features of the browser. He is also a jQuery team member, developed the HTML5 Boilerplate, and is a curator of HTML Rocks as well as the Creator of HTML5 Please – both of which you should have bookmarked.


    Lea Verou

    Lea Verou is a front-end developer whizz from Greece. She is an influential member of the industry, and she speaks at many conferences and events on issues regarding primarily CSS and HTML, highlighting modern techniques. She is also an advocate of Polyfills, as am I. Check out her projects page, there are dozens of useful tools that can help your projects.



    There’s a lot more, I’ll be adding to this over time.

  2. What were American Airlines thinking?

    Leave a Comment

    American Airlines, the troubled American airline currently in chapter 11 bankruptcy, recently refreshed its branding. Along with the branding refresh comes a brand spanking new website which reflects the new logo and colours. Initial impressions are positive.

    Well, now this is nice. It is extremely clean and de-cluttered and it feels very fresh. I love the use of big images as well as the design focusing on the flight search. I also find the tabbed forms an elegant method of dealing with multiple forms without clutter. Overall, this is a very good web design, and I suspect their conversion rates will sky rocket as a result. This is a design that leaves a last, positive impression.

    Then we move on to the booking page, and sadly we’re greeted with this.

    What clearly has happened here is the website has been re-designed around the existing booking system and forms. What this means is that on the booking page, you have the old form, with its old styles, surrounded by the header and footer of the new website. That the home page precedes the booking page also does the site no favours, it suddenly feels jammed together. Notable issues:

    • Submit and Clear form buttons are a usability problem. Whilst red is often a good choice for a call to action, in a web form I would argue it more likely symbolises clearing or resetting the form. The tiny size of the buttons also makes them difficult to identify and locate.
    • Far too many shades of blue. When your branding uses a specific colour, you should try not to deviate from this too much in your web designs. Using the same shade of blue throughout produces a more coherent design that matches your branding, which helps reinforce it.
    • In this day and age with tablet and mobile browsing usage on the up, as well as larger desktop screens, form fields need to be bigger than default. At this size, they are small and difficult to use and the text inside is small and hard to read.
    • Separate drop downs for date fields. This is quite common, but with many options available for date pickers it seems a strange choice, and makes the form much slower to fill in. Providing a visual representation of dates as a calendar makes it much easier for users.

    The booking form is generally pretty ugly, dated looking and not particularly user friendly. It seems strange that AA undertook such a massive re-branding exercise yet completely neglected to change the most important element of their website. It may just be a case that the form is still to be replaced, which begs the question, why didn’t AA wait until the form was re-designed before renewing the rest of the website?

    When you explore the site further, it soon becomes apparent this isn’t just an issue with the booking page. Visiting other pages also brings about this issue of a clash between the header and footer of the new website and branding, and the content of the old website, still styled how it was before. The end result is a website that is a mash up of an old website and a new website, which seems remarkable, as well as being confusing, lacking cohesion and difficult to use.

    No company of the size of AA should release an unfinished website, and old and new websites should almost never be mashed together in this manner.

  3. Using PHP to fix database irregularities

    Leave a Comment

    We often have to use databases in our projects, and sometimes these databases have been sourced from elsewhere. The problem we often find is that these databases can be incomplete,  missing information, or not formatted how we want.

    Let’s say for example that you’re pulling strings out of a database, but some of them are missing a word that for some reason or another, is critical to our application. There are ways to comb through databases to fix these issues, but if for some reason you can’t get that working, you can always use PHP.

    You can use either stripos or strpos to check for missing words from a string. The difference is stripos is non case sensitive, whereas strpos is case sensitive. Simply replace “word” above with the word you are looking for. The script will then check the first value of the string for the presence of the word, and if it is missing it adds it in. If you need to check a different value in your string just change the parameter. For example, to check the second value, use [1] instead of [0].

  4. Use WordPress get_template_directory function in external JavaScript

    1 Comment

    Here’s a useful snippet. If you develop for WordPress, you’ve probably found you either have to hard code URLs in your external JavaScript…or put the JavaScript in line. Neither of these is ideal because the first won’t work when the theme is installed on a different URL, and the second will make your header look bloated and possibly slow your site down. It’s just not good practice to have JavaScript in line.

    But there is a way, and it’s very simple. First, you need to declare a JavaScript variable in your Head.

    Make sure this is before your external JavaScript. Now, where you need to echo that function in your script, you simply echo the variable instead. E.g:

    If you ever find yourself needing to use other WordPress theme functions in your Javascript, there’s no reason you couldn’t use the same principle with other functions.

  5. New Website

    I have just updated my website with a new design. I hope you like it! It is, as expected, fully responsive, so by all means do enjoy visiting on your mobile or tablet.

  6. Elliptical Rounded Corners CSS3 Browser Support

    Leave a Comment

    So you want rounded corners, but you don’t want them perfectly round. Seeing perfectly rounded corners everywhere looks almost as rigid as plain ole’ square boxes can. But if you didn’t know already, you will now – you can do elliptical rounding in CSS. You simply specify two values, the horizontal radius and the vertical radius.

    Unfortunately, each browser engine decided on different ways of interpreting these values, leading to some seriously bloated code, which is probably why you haven’t seen much about it. The good news is the code has got simpler, and updates to Firefox, Chrome and IE means the latest versions of these browsers (and IE9) don’t need vendor prefixes and use the same standardized syntax.

    Old Code

    Short-hand old code (FF)

    Argh. What a mess! But now we can settle with just the following.

    New Code (Chrome, FF, IE9+)

    As I say though, this is with the latest versions of these browsers so if you’re concerned about users stuck on old versions of FF and Chrome you may want the prefixes anyway. And of course as you’d expect, there’s no IE8 or below support. I also can’t get my copy of Opera working so if you’re bothered about Opera support you’ll have to test that for yourself! Here’s the Codepen: http://codepen.io/anon/pen/hyErL

  7. MailChimp API cURL

    Leave a Comment

    Please note, this article assumes you have a basic understanding of PHP.

    If you’re looking to integrate MailChimp subscription into an existing web form you’ve written yourself in HTML and PHP, hopefully this will help. Firstly, make sure you have a list setup in MailChimp for addresses to be added to. Also make sure when you set up the list, you add the relevant “Merge” tags you need. Examples include first name, last name, address etc.

    We’re going to use the cURL method, which I find is the easiest. We’re essentially using cURL to send the information we want to MailChimps servers.


    1. In your Mailchimp account, sign up for an API key and note it down.
    2. Go into your list settings, at the bottom is a unique ID. Note it down too.


    In this example, I’m assuming your form script has something like this going on:



    In other words, assuming the information validates, we’re then displaying a page that confirms the submission. We ideally only want to fire off our MailChimp request after we have sent the form, so we’re going to place the MailChimp code inside our success statement.

    The code above also checks a check box we have in our form that allows the person submitting the form to choose whether they subscribe or not. So they only get added if they want to be. The id of the checkbox in this example is “Subscription” but yours may be different, so change it as appropriate.

    If you are asking for peoples names in one field, rather than separate first/last name fields, use PHP’s explode function to split the name, you can also write it to exclude middle names etc.

    Replace the API-KEY and LIST-ID with your relevant information. You’ll also need to setup your MERGE tags. In this example, I have two tags for “FNAME” and “LNAME”. If you have the same tags you can leave the code, but if you have different tags or need to add more, what you need to do first is add them to the array at the top. When you have done that, you can add them to the URL.

    Place that in the URL (after the other Merge tags). Then you reference your array after the URL, using:

    That should basically be it. It took me a lot of trial and error to get this all right, as I’m not a PHP developer, but if you use this code it should be fairly straightforward for you to setup.

  8. Expanding Excerpts the non-Ajax way

    Leave a Comment

    A lot of blogs have this feature whereby posts are listed as Excerpts, the full post can then be dynamically loaded by the user. If your full post is still only text and small images, then I feel AJAX is overkill as loading this content on page load is not likely to slow the site down significantly, and whilst AJAX is great, it can be annoying for the user to have to wait for the content to be fetched and loaded.

  9. Pass multiple values from one option through the WordPress Settings API

    Leave a Comment

    What happens if you want to pass multiple values through the WordPress settings API with the user only making one selection? Just because the user selects a single option, it doesn’t always mean you only want to pass one value. For example, when adding Google Fonts to my WordPress dashboard plugin, I encountered a problem. For fonts comprising two words, Open Sans being an example, the font name would be passed with a + sign between the two words in the URL. So for the font to load, the value needed to be Open+Sans.

    But of course, the font-family name is without the +, and you can’t change the font-family name when using Google Fonts. Essentially, I needed the user to be able to choose “Open Sans”, but two values be passed – Open Sans and Open+Sans.

    So how do you do this? If you know PHP you’ll already know how more than likely, and it basically involves the explode command. First, put both values in your Option value field, separated by a comma, or whatever delimeter you prefer. Because you’ll want the selected option to be displayed, make sure you amend your IF statement to include the whole array.

    Second, when you pull through your Option value, you’ll then need to separate the values so you can use them separately – this is where explode comes in handy.

    We can then pass the variables separately, using $url[0] and $url[1].

    The numbers represent which value in the array you want to pass. If you need to use large arrays, this is fine, just change the numbers to reflect the values you want. For example, if you have six values in your array, and you only want the fourth, use [4].
