[htmltmpl] New to this - conditional problem i think

[Thomas N. <th...@te...>]

Hi all

I'm new to html-template and fairly new to perl too.

Anyway I have managed to set up a html form that inputs certain values 
to a perlscript which in turn queries an mysql database and then 
outputs the results using html:template and it works very nicely with 
one exception. If i enter a value in the form that is not in the 
database i receive an error. Since i use

push @{$rows}, $_ while $_ = $sth->fetchrow_hashref();

i figured..hey this is a hash so i can use

if (exists $rows{$fornamn}) etc .. but alas no. apparently push gets an 
array and not a hash if I now get it correctly.

Anyway, i was thinking, maybe i can set a conditional in the template 
so that depending on the value of a row i can output different html 
code. What i need is to alert the uses that his or her query resulted 
in no hits. I tried searching in the list but i'm not quite sure what 
to search for. I would very much appreciate it if someone could help me 
in the right direction.

Thanks
