[TYPO3-english] Typoscript stdWrap if COA element not empty

[Stefan Reichelt]

Hello Arun,

although I have to agree with Bernd that you really should move the
wrapping into the same piece of code (you typoscript object would be
best imho).

But if you really really really reeeeally can't do that, here is a
possible solution (untested):

--
lib.contactbox = COA
lib.contactbox {
    10 < plugin.tx_myext_pi1

    # If empty, load a register and add a variable into it
    10.stdWrap.ifEmpty.cObject = LOAD_REGISTER
    10.stdWrap.ifEmpty.cObject.tx_myext_pi1_isEmpty = 1

    20 < styles.content.get
    20.select.where = colPos = 3

    # Only use wrap if register variable is not set
    stdWrap.wrap = |</div>
    stdWrap.wrap.if.isNull.data = register:tx_myext_pi1_isEmpty

    # Restore register to before last LOAD_REGISTER use
    99 = RESTORE_REGISTER
}

--

Instead of ifEmpty you could also try ifBlank. See which works better.

Instead of isNull you could also try isFalse. I don't know how
stdWrap.if handles register variables that do not exist. Please write
back which of them works. :)


Kind regards
Stefan
