Here I discuss the creation of a view helper for modifying HTML tags, and more specifically body tags. The created view helper allows functionality similar to the head*/inlineScript view helpers already in the standard Zend Framework view helpers, but allows the programmatic modification of tag attributes. Definitely check out the demo page and the code on github.
The standard Zend Framework view helpers are a great set of tools for streamlining mundane view tasks and allowing for the modification/addition of scripts and header blocks (generally held in the layout) from within the view without applying ugly hacks (i.e. the head*/inlineScript view helpers).
Upon occasion I have found need to make modifications to the <body> tag, for example adding an onload, class, or style attribute etc. I also required to be able to perform this from within other view helpers. Take this following contrived example…
On website X, certain pages include standard dojo forms. These dojo forms are held within view helpers for convenience. Generally it has been decided not to include the dojo CSS classes in the body tag and only add them when necessary. There maybe several view helpers on the page that need to add their own attributes to the body tag. (I said it was contrived)
The code is available in my GIT repository @ github and the demo page.
