Hi folks,
this is just a little tip for those of you who dislike their xhtml to end up as tag soup and still prefer to send out Html 4.01 strict. Here is how to make all helper functions in Cake 1.2 output Html 4.01 compliant markup instead of xhtml:
{
/**
* This is the constructor for our AppHelper class that we use to make all helper output html 4.01
* compatible markup.
*
* @return AppHelper
*/
function __construct()
{
// Loop through all tags in this helper
foreach ($this->tags as $tag => $html)
{
// Replace all xhtml style tag closings with html 4.01 strict compatible ones
$this->tags[$tag] = r('/>', '>', $html);
}
}
}
If you wonder why somebody would prefer the good old html over the all-so-hyped xhtml, read a little bit about it here.

Nate Klaiber: Excellent idea. I'll talk with nate (abele) and see what he thinks about this ; ).
doesn't this seem extremely inefficient/expensive to go through all the tags on a page and strip out these slashes?
jared: Sure. Would it make you feel better if I'd use a lambda-style (create_function) function and use array_walk? *g*. No honestly, this is something that should be in the core imho and maybe it will be at some point. For now I see this as a pragmatic work-around and not the most efficient or beautiful solution to the problem. Hope that's ok ; ).
It's not all the tags on the page, it's all the tags generated by helpers.
It would seem much more effective to add your own tags (without the closing slashes in this case). See this ticket:
https://trac.cakephp.org/ticket/2081
You can find the default tags in /cake/libs/view/helpers/html.php at the top. Copy that into a new file named tags.php and put it in your /app/config directory. I just tried this out myself and it seems to work quite well.
I also changed the doctype in my layout by calling:
$html->docType('html4-strict')
which completes the changeover to HTML 4.01 strict.
Well, I'm lazy, I like to keep things DRY and I don't really care about the 2ms spent on this one way or the other. The only 'proper' way to handle this is by having native support for it in the framework (= your docType change also changes tags). Other then that everything is a hack and this one is the least painful to implement and maintain so it's my favourite : ).
thanks really

I pretty much built the same thing this afternoon (See my recent post on CakePHP). One of the things I wished you could change was the output of markup based on the proper doctype that you could select. I use HTML4 strict for my pages, and I didn't want to manually have to change the core or add new tags and a new helper.
Nice job :)
