James,
This works for me [% ${"field$i"} %] as in:
[% i = 1 %]
[% WHILE i <= max %]
<input type="text" name="field[% i %]" size="24" value="[% ${"field$i"}
%]"> [% i = i + 1 %] [% END %]

[% WHILE i <= max %]
<input type="text" name="field[% i %]" size="24" value="[% "field$i"
%]"> [% i = i + 1 %] [% END %]
Using this snippet of code, I am looping through a list of fields 1
through max. This works great when the field key I am looking for
actually exists.
If I happen upon a field that isn't in the hash then it just prints out
"fieldn".
Here is a sample of output with a hash that might be passed in:
{
field1 => 'foo',
field2 => 'bar',
max => 3,
}
<input type="text" name="field1" size="24" value="foo"> <input
type="text" name="field2" size="24" value="bar"> <input type="text"
name="field3" size="24" value="field3">
The last input is what I am trying to avoid. I'd like the value to be
blank.
