[FLOW3-general] Feature in TagBuilder

[Adrian Föder]

Hi list,

I of course like the current implementation of the TagBuilder very much; 
I ever liked to built something like that on my own.
I would like to come up with an improvement that I think makes sense; 
it's about the "addAttribute" thing.

Currently, the attributes are "just" an array with attribute names as 
keys and their values as... values.
In HTML, sometimes it comes to "collections" inside attributes, I think 
especially about "class" and "style". Multiple class names resp. style 
directives are allowed inside a class/style attribute.
This circumstance is also taken into account when it comes to the W3C 
element selector "[att~=val]" 
http://www.w3.org/TR/css3-selectors/#attribute-selectors

My thought now is, that it would be nice to make attributes configurable 
to hold collections, with a per-attribute definable separator (that 
would be [space] on "class", and [;] on "style".

So if you

->addAttribute('class', 'btn')

and there's already an attribute "class" present, and it's configured to 
hold collections, that value is appended to the existing value.

same goes to ->removeAttribute; in this case there has some RegEx magic 
to be happen in the background.


To avoid problems and make verbs less ambiguous, we could introduce

->setAttribute()

, which definately overrides any present values.


"What do you think"?


Best,

Adrian
