[TYPO3-english] Check with Typoscript if Templavoila "Link field" is set

Hi Søren,

Ok, I see.
It is still possible, but a bit more tricky.
You could still insert a lib into that field, but the trickiest problem is that 
you cannot access the TV field in your normal TS template, so you'll have to 
insert some TS inside the TV DS (data structure).

First, you change the readonlinelink-field into a link field.

Then you open the DS and find the part for this field.
There you add the typoscript part:

			<TypoScript><![CDATA[
	10 = TEXT
	10.value = {$readonlinelinktext.da}
	10.typolink {
	     parameter.data = getIndpEnv:TYPO3_REQUEST_URL
	     parameter.override.field = field_readonlinelink
	     title = {$readonlinelinktext.da}
	}
                     ]]></TypoScript>


Next, you need to use the trick described here [1] to access your constants 
inside a TV DS. (It's horendous, sorry) But of course you can also give your 
editors a sense of flexibility by changing the constant into another TV field. 
Then you can use field = field_readonlinelinktext

The only thing you have to take care of is that such changes in the DS get lost 
when you click 'modify DS/TO' (the button for which TV always warns you) and 
save. But of course you can always find back your changes in history and redo them.

It may have been more elegant if you could do this trick in the normal TS 
templates, but that doesn't work unless you would find a way around this:

"The scope of the TV fields are kind of tricky, the fields are not available 
from within your normal TStemplate, actually they are only available from the 
same level (ie. you can not access fields within a section from a field outside 
of the section) within the TVDS."

See [2] for more info

Anyway, I hope you get hang of it and get it to work.
Time to go to sleep.

Cheers,
Loek
