Re: HTML::Template if key of hash matches value of hash.

The trick is to add some more logic to your perl code:

my $has_approved_records = 0;
my $reqs;
while (my $row = $sth->fetchrow_arrayref) {
    $has_approved_records 1 = if $row->{status} eq 'Approved';
    push @$reqs, $row;
}
...
$template->param(REQS => $reqs, HAS_APPROVED_RECORDS => $has_approved_
+records);

And in the template

<TMPL_IF HAS_APPROVED_RECORDS>
    <span class="hotspot" onmouseover="tooltip.show('<strong>Approved 
+Vacation Requests</strong><br /><TMPL_VAR DATE>');" onmouseout="toolt
+ip.hide();">
</TMPL_IF>

While not exactly what I was looking for (my fault for lacking clarity in my post), your reply was very helpful. Thank you. I will be sure to post my code when I figure it out. I figured a break was what was needed to solve this issue.

Just wanted to post my code as an update on how I did this in case anyone is ever interested in the same thing: The trick was in my SQL statement...

my $sth = $dbh->prepare(
            " 
               select t.id,t.user,t.email,t.status,t.date,t.req_date, 
               ( SELECT 
                GROUP_CONCAT( (case when status = 'Approved' then user
+ end) separator ', ') 
                FROM requests s WHERE s.date = t.date) 
                AS approved 
                FROM requests t 
                WHERE status = 'Pending'
                AND req_email = '$email'
                AND date >= '$date'
                ORDER BY employee,date
            "
        );
        $sth->execute();
        my $reqs;
        push @{$reqs}, $_ while $_ = $sth->fetchrow_hashref();

        my $template = HTML::Template->new( filename => 'approve.html'
+ );
        $template->param(
            REQS     => $reqs,
        );
        print $template->output();

And here's my template code:

<TMPL_IF REQS>
    <form>
        <table class=approve>
            <tr>
                <th class=approve>Approve</th>
                <th class=approve>Decline</th>
                <th class=approve>Date</th>
                <th class=approve>Employee</th>
                <th class=approve>Status</th>
                <th class=approve>Request Date</th>
            </tr>
            <TMPL_LOOP NAME=REQS>
                <tr class=approve>
                    <td class=approve><input type=radio name=apid<TMPL
+_VAR NAME=ID> value=Approved></td>
                    <td class=approve><input type=radio name=apid<TMPL

                    <td class=approve>
                        <TMPL_IF NAME=APPROVED>
                            <span class="hotspot" onmouseover="tooltip

                        <TMPL_IF NAME=APPROVED>
                            </span>
                            <script type="text/javascript" language="j

                        </TMPL_IF>

                    <td class=approve><TMPL_VAR NAME=USER></td>
                    <td class=approve><TMPL_VAR NAME=STATUS></td>
                    <td class=approve><TMPL_VAR NAME=REQ_DATE></td>
                    <input type=hidden value=<TMPL_VAR EMAIL> name=emp

                    <input type=hidden value=<TMPL_VAR DATE> name=date

                </tr>
            </TMPL_LOOP>
            <tr class=approve>
                <th class=approve colspan=6>
                    <input type=submit value="Approve / Decline">

                </th>
            </tr>
        </table>
    </form>
<TMPL_ELSE>
<br /><b>There are no pending requests!</b><br />
