[TYPO3] help needed - captions splits??

Hit the RETURN key to fast.

And you will notice that split is a stdWrap function and not just a boolean
switch.
Take a look at this
http://typo3.org/documentation/document-library/references/doc_core_tsref/current/view/5/6/
to find out how it works.
The parameter returnKey has been implemented in T3 4.0 and is not yet
documented in TSref.
This enables the split function to get the information which part of the
splitted content should be used from another source.
In this case it's a register containing the current image number.

Here's the complete code of CSS styled content which is related to captions
and splitting them into smaller chunks:

caption {
    1 = TEXT
    1 {
        field = imagecaption
        required = 1
        parseFunc =< lib.parseFunc
        br = 1
        fontTag = <p class="csc-caption">|</p>
        wrapAlign.field = imagecaption_position
        split.token.char = 10
        split.token.if.isPositive = {$styles.content.imgtext.imageTextSplit}
+ {$styles.content.imgtext.captionSplit}
        split.returnKey.data = register : IMAGE_NUM
    }
}
captionSplit = {$styles.content.imgtext.captionSplit}
imageTextSplit = {$styles.content.imgtext.imageTextSplit}

You can remove the constants if you like so it will be always activated and
the code looks like this:

tt_content.image.20 {
###.... blah, blah, some other TS stuff ...
caption {
    1 = TEXT
    1 {
        field = imagecaption
        required = 1
        parseFunc =< lib.parseFunc
        br = 1
        fontTag = <p class="csc-caption">|</p>
        wrapAlign.field = imagecaption_position
        split.token.char = 10
        split.returnKey.data = register : IMAGE_NUM
    }
}
captionSplit = 1
imageTextSplit = 1
###.... blah, blah, some other TS stuff ...
}

This has to be part of

tt_content.image.20
AND
tt_content.textpic.20

and this means you have to copy the whole setup after changing it if you are
not using CSS-styled-content original TS setup.
In the original setup there is a reference operator that will copy changes
to tt_content.image.20 automatically.

tt_content.textpic {
###.... blah, blah, some other TS stuff ...
   20 =< tt_content.image.20
###.... blah, blah, some other TS stuff ...
}

If this is not the case with your template you will have to implement it to
make sure that caption split is activated for both: "Images" and "Text with
images".
This will work with TYPO3 4.0X only, since the register: IMAGE_NUM was not
available in earlier versions.
