DBI, HTML::Template and loops

Hello Monks,

I am new to perl, and I have been taking pieces and parts from other scripts I have found in an effort to try and get comfortable with perl. I am trying to query a database and display the information that I get on a webpage using HTML::Template.

Here is what I am using to get the data:

my $sth = $dbh->prepare( "SELECT alpha FROM main WHERE alpha LIKE '%$s
+earch_ip %'" );
$sth->execute();
my ($complete_match) = $sth->fetchrow_array;
[download]

That gets my information out of the database, but how do I get that into HTML::Template? I have tried this:

$template->param(cm => $complete_match);
print $CGI->header( );
print $CGI->title("returned data!");
print $template->output;
[download]

That gives me the follwoing error:

HTML::Template::param() : attempt to set parameter 'cm' with a scalar - parameter is not a TMPL_VAR! at /var/www/asd/www.pl line 60

If someone could point me in the right direction, it would be much appreciated.

Thank you very much.

Your template must include `<tmpl_var cm> ...` [download] also take a look at placeholders for you SQL statements and at the `die_on_bad_params` option for HTML::Template Boris	[reply] [d/l]

Yes, for placeholders see: Create Better Perl and SQL with Placeholders The Phrasebook Design Pattern Google search results for: placeholders sql perl HTH. Walking the road to enlightenment... I found a penguin and a camel on the way..... Fancy a yourname@perl.me.uk? Just ask!!!	[reply]

`$complete_match` must be a ref to a AoH (array of hashes) for a `<tmpl_loop>` Consider: `my $complete_match = $sth->fetchall_arrayref({}); $template->param(someloop=>$complete_match); HTML: <tmpl_loop someloop> <tmpl_var column1><tmpl_var column 2> etc... </tmpl_loop>` [download] Update: That error can also be caused by naming your form element the same name as your tmpl_loop name. They have to be different. —Brad "The important work of moving the world forward does not wait to be done by perfect men." George Eliot	[reply] [d/l] [select]
