[TYPO3-mvc] viewhelper for first char register

[Claus Due]

Hi Johannes,

It's fairly simple. You can use any value as the "string" argument - in your case I guess {hotel.name}.

You can place the ViewHelper anywhere, but I suggest the root of the "ViewHelpers" directory (since this is not a widget). You would use this by:

1) In the template, register the namespace for your ViewHelpers, fx {namespace hotel=Tx_Hotel_ViewHelpers}
2) Use <hotel:initialLetter string="{hotel.name}" /> in each iteration of your <f:for> - it will only render anything if the {hotel.name} starts with a different letter than the last time the <hotel:initialLetter> was used. Should be exactly what you need.

There's no such thing ;) ask away!

Cheers,
Claus
