Monday Monks,
Why isn't my hash passed to TT for processing? When I run this, I get one iteration of the template html and with no values inserted.
In the script (snippet):
use DBI;
use Template;
#get users list from database
$sql = "SELECT user_id, ufname, ulname FROM users";
$sth = $dbh->prepare($sql) or die("Could not prepare!" . $dbh->errstr)
+;
$sth->execute() or die("Could not execute!" . $dbh->errstr);
# build data structure
while (($user_id, $ufname, $ulname) = $sth->fetchrow_array()) {
$data{$user_id} = {
ufname => $ufname,
ulname => $ulname
}
}
$sth->finish;
#prep variables for TT
$vars = {
data => %data,
today => $today
};
$template_file = "./template/my_file.htm";
#process file
$template->process($template_file, $vars);
and in the template
Call list for [% today %]
<p>
[% FOREACH user IN data %]
Be sure to call [% user.ulname %], [% user.ufname %]
[% END %]
I suspect there's something wrong with the way I'm passing the data hash?
Thanks.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
