OK, so here's another thing that I thought I knew, but apparently I had remembered my results wrong.

 

Say you want to find something in a list of items like this:

$value = 'apple';
$multiValue = 'orange¶apple¶banana'

It was my recollection that you could use this statement: 

If ( $value = $multiValue ; 1 ; 0 )

to determine if the value 'apple' existed somewhere in the field or multi-value string/list.  That doesn't appear to work, even if the value being checked for is the first value in the list.  I would have sworn (I must swear a lot) that I had done this before.  But apparently not, because it doesn't work.

 

Instead I have resorted to using position(): 

If ( Position ( $multiValue ; $value ; 1 ; 1 ) > 0 ; 1 ; 0 )

Any other techniques for checking the existence of a value in a list?  Something that is faster?

 

Thanks,

C

Try:

not IsEmpty ( FilterValues ( $Value ; $multiValues ) )

Position() can give false positives because it can match partial words.
