Closer To The Ideal

Some fellow posted a commerical notice to the comp.lang.php newsgroup. For a mere $79 per developer, you can get a PHP framework that does all the same stuff as the free, open-source PHP frameworks. And it has all the same problems, too. In an old post on the Category4 weblog I was ranting about the problems that stem from generating HTML from inside of PHP code. When a PHP framework generates HTML and CSS from inside the PHP code, then programmers end up working on problems that designers could solve much faster. Consider this problem, which the PHP Developers Kit offers as an example of all the wonderful things you can do if you use their $79 framework:

The workhorse of PHP Kit is the container class . It is a box containing other objects, like text, links, paragraphs and even other containers. It is under CSS control so you may create a container using several dozen options, like background color, border style, border color, font size and font color.

Note: the containers above displayed correctly in Microsoft IE when displayed inline (left to right). However, Mozilla Firefox version 1.5.0.4 displayed them left to right but with no width or height except for the width of their borders. When displayed as block (one above the other), Mozilla displayed their size correctly. The display property (inline or block) is not suppose to effect an element’s assigned width and height.

So, um, you really should be able to control these containers from your code, but when you run into a problem, such as different browsers interpreting your CSS differently, you (the programmer) are stuck solving it. The designer, who specializes in CSS, can not solve your CSS problem for you, because they don’t know how to edit the PHP code that generates the CSS. Ideally, all CSS issues should be the domain of your designers, not your programmers, but when all the CSS is controlled by PHP code, then solving this problem is shifted from the designers to the programmers. This leads to workflow problems - in too many web design shops the programmers have too much work to do and the designers too little, and frameworks such as this are to blame. This is bad economics - to the extent that your programmers are paid more than your designers you should be trying to shift work from programmers to designers.

Concentrating all of the important design work into the hands of the programmers is also bad for morale - I’ve worked in shops where the designers had no work to do because they were waiting for the programmers to finish a bit of PHP/CSS template code. It is demeaning and embarrassing for the designers to have no work. I’ve seen them try to make busy work for themselves and they always look a little embarrassed and ashamed. A well-run web design shop will strive to avoid this.

Designers are focused on communicating with other humans, programmers are focused on communicating with machines. One’s users and clients suffer when the actual power to design is taken away from designers and given (even accidentally) to programmers. It is a rare programmer whose insight into user behavior matches that of a highly skilled designer. An intuitive sense of the user experience is the most important skill that a good designer brings to their work. If all the real design power is in the hands of the programmers, one’s websites and web software are likely to be less intuitive than what might have otherwise been achieved. By contrast, a framework that maximizes the power of the designers is a framework that maximizes the chances of a great user experience being achieved.

Again, let me repeat (as I said in that previous post), frameworks like this (I mean the one I’m criticizing) are fine for the individual freelancer who does all their own programming and design work. But these frameworks are harmful to web design firms that work on large sites and who, therefore, need programmers and designers to work together. As soon as you have a division of labor, you need a framework that facillitates workflow, rather than blocks it.

The last time I wrote on this issue (back when I still worked at Category4) a fellow named Matt responded:

While I generally agree on your view of no html in your php, I think there are exceptions. It’s really about choosing what for when and where. For example, form elements being generated by code is acceptable to me. Even as a designer, I would think that looking at a page with a few php/template tags would be better than a page with lots of html; it’s still code. Less control, but as long as the code is doing what you want then there is no worry. And you could always either override/extend the classes generating the code or hack it…. I think that my point is that one could continue to mull over what to use and prematurely optimize resources to the point of getting nothing done.

I’ll say again, if an individual is doing both the programming and the designing, then putting HTML into the PHP might speed things up for them, but as soon as the jobs of programmer and designer are split, then anything that robs designers of their power is likely to lead to work-flow problems. And those cost money, time, morale and sometimes management focus. They also limit the ability of the designers to achieve a great user experience. Matt suggests that form code can be generated by PHP code, but if you do that, you will very likely get cookie-cutter forms. Forms are the single most important area for designers to innovate a great user experience, but the ability of designers to innovate is wiped out if the HTML is generated by PHP code.

As to “you could always either override/extend the classes generating the code or hack it”, only a programmer can do this. Designers can’t do this on their own. If the designers need this done, then they need to wait on the programmer to do it. And then, once again, you end up with a work-flow problem that damages the productivity of the firm. Either the firm’s profits will be reduced or the costs must be past along to the client, driving up what they must pay for the project.

As to “one could continue to mull over what to use and prematurely optimize resources to the point of getting nothing done”, I’m sorry I haven’t stressed this, but the opinions I’m expressing have grown up on me slowly over the last 5 years. In 2002 I started work on a PHP/MySql content management system and I made every mistake that I’m now critical of. Back then, I wrote functions to simplify my forms, such as:

textInput(”author”);

All the HTML was in the function. It’s exactly what I’m now critical of. So what I’m expressing in this post isn’t premature optimization. It’s way-overdue optimization. I’m looking back at the mistakes I’ve made over the last 5 years and I’m trying to express what I’ve learned so others might now avoid making the same mistakes I’ve made.
