if-PREFIX-pos
Summary
- [if-PREFIX-pos N] column value is true [else] column value is false [/else] [/if-PREFIX-pos]
Description
This loop sub-tag looks up the value of the array element
associated with the looping tag's current row.
Each loop iteration returns an array of columns,
set in searches with
mv_return_fields.
If the value of the Nth column
(numbered from zero) evaluates true (non-blank and non-zero)
then the IF text will be returned.
If it evaluates false then the text in the optional
[else] block will be returned.
You can reverse the IF text and ELSE text by using the "!" (not) operator,
as follows:
[if-PREFIX-pos !N]
IF (not found) text
[else]
ELSE (found) text
[/else]
[/if-PREFIX-pos]
|
You can test the column for a specific value,
using any of the Interchange test operators,
as follows:
[if-PREFIX-pos N =~ /kevin|walsh/]
Yay!
[else]
Bah!
[/else]
[/if-PREFIX-pos]
