I am new to the HTML::Template module, as you will see:<br>
<br>
I have successfully generated the <tmpl_loop> using an array
which contains a hash reference.<br>
<br>
However, in the html page I want to be able to loop through my hash
without knowing the names of the keys.<br>
What is the best way to do this?<br>
<br>
eg. in my cgi script I have:<br>
<br>
<i>my %price_hash = (<br>
"key1" => "val1", <br>
"key2" => "val2", <br>
"key3" => "val3", <br>
"key89" => "val89"<br>
);<br>
<br>
push (@price_array, \%price_hash);<br>
$param->{"price_loop"} = \@price_array;</i><br>
<br>
So that in the html page I can use:<br>
<i><tmpl_loop name="price_loop"><br>
</i><i>....</i><br>
<i></tmpl_loop><br>
<br>
</i>I know I can use <i><br>
<tmpl_var name="key89"><br>
</i>in the loop, but to output "val89" that relies on me knowing that
key89 exists, and its name..<i><br>
<br>
</i><b>How can I just loop through the hash printing out the keys and
values, without knowing the keys?</b><i><br>
<br>
