I have several templates that require an ID variable to be passed to
them. When the templates load, they run a query "WHERE (COUNTY_NO =
'#ID#')" -- ID is a CGI variable.
I'm trying to account for users that will try to load these templates
without the ID, but I can't make either IsDefined or ParameterExists
work for me. If the user attempts to load without the proper ID, I'd
like to redirect them to another page where I let them select the county
and type of information they want.
I've tried every permutation I can find, but I can't get it to work. I'd
simply like to:
1) Load the page and check for cgi variable
2) If variable exists, process the page
3) If not, redirect user to another page?
Any suggestions?
Also, I understand I'm not doing this very efficiently. Rather than
having different templates for particular types of information, I should
be using the same template and creating the HTML using some sort of
"method". However, I haven't yet come across an explanation of how to do
this (e.g., the way Allaire presents everything with an ID
&Method="..."). Could anyone direct me to a resource for a description?
TIA,
