[TYPO3-english] question on TSref manual

[François Suter]

Hi Tom,

It means that the whole object (i.e. "stuff") will be handled only if 
the header field is not empty.

The "if" construct is rather awkward to use. The basics are that if it 
returns true, the object it applies to is rendered. Otherwise it returns 
empty.

Now "if" can evaluate a variety of conditions, one being simply whether 
some value is true or not. In this case the value being evaluated is the 
"header" field of the content element and the test will return false is 
the header field is empty.

I hope this helps you a bit. Understanding the TypoScript "if" is not 
easy at first. The reference is there:

http://typo3.org/documentation/document-library/core-documentation/doc_core_tsref/4.7.0/view/1/5/#id553579

but you'll definitely need to work yourself through several examples 
before you feel confident about it. It's rather counter-intuitive. Don't 
lose faith ;-)

Cheers
