Hi Lori,
In your loop where you are pushing onto @loop_data, you'd want to add an
additional variable to your hashref that will indicate whether or not is
drillable. So inside your loop, you might do something like this:
for (some_loop_condition) {
if (row_is_drillable) {
push @loop_data, {id => $this,
rowname => $that,
drillable => 1}
} else {
push @loop_data, {id => $this,
rowname => $that,
drillable => 0}
}
}
$tmpl->param(LOOP_DATA => [EMAIL PROTECTED]);
Then inside your template:
<TMPL_LOOP NAME=LOOP_DATA>
ID: <TMPL_VAR NAME=ID><br>
Name: <TMPL_VAR NAME=ROWNAME><br>
Drillable?: <TMPL_IF NAME=DRILLABLE>Yes<TMPL_ELSE>No</TMPL_IF>
</TMPL_LOOP>
Basically, you can use TMPL_IF on any variable in your loop. Although, if a
drillable row requires a URL or some other bit of information, you can get away
without an explicit drillable variable and use the presence or absence of the
URL to indicate if the row is drillable.
Remember what true and false are in perl and that will help you. False is 0
(the numeric value), "0" (a string containing the number 0), undef (undefined)
or a empty string ('' or ""). Anything else is true. And that's how
HTML::Tempalte works, as well, when dealing with TMPL_IF.
Clear as mud, right? :) Hope this helps.
Good luck!
