[htmltmpl] Generating dynamically named tags

[Dan H. <dan...@re...>]

Hi All

I'm writing a template for use with CGI:Application::Plugin::ValidateRM.
C::A::P::VRM expects every field that requires validation to have a =
matching
field  with an "err_" prefix (i.e  err_field_name).

My field names are dynamic, e.g.

<tmpl_loop name=3Dapplication_parameters>
<input type=3D"Text" name=3D"<tmpl_var name=3Dfield_name>" =
value=3D"<tmpl_var
name=3Dfield_value>
</tmpl_loop>

but I can't figure out the best way to specify the error field. =
Obviously=20

<tmpl_var name=3Derr_<tmpl_var name=3Dparameter>>=20

doesn't work

Any ideas appreciated

Thanks

Dan

Generate it in the Perl script instead, in an H::T var named
"err_field_name". In the template just place:
<tmpl_var name=3Derr_field_name>

Thanks for your reply. I'm not clear how it works. If I have a field called
"max_rows", then the parsed template will be

<input type="Text" name="max_rows"> value="5> err_max_rows

What should happen is that <tmpl_var err_max_rows> will be empty when the
template is displayed if there is no error, and will have the error message
if there is an error. This isn't done by me - it's done by
CGI:Application::Plugin::ValidateRM, DFV and HTML::FillInForm.

Thanks
