Hi, Justin.
Thanks very much for the reponse.
Yeah, this is a SUPER simplified form of my question, so please don't
expect it to make sense. Heh.
Basically, I have a php file with dozens of functions in it. I want ONE of
them to get called when a link is clicked.
Currently, I achieve this with the use of HTML forms. My form generates a
list of options. And the user has to select an option, then click the
SUBMIT button.
But I want to make it a one-step process, whereby the user only needs to
click on the option.
Of course, you can't achieve this in a form with JavaScript, but the
JavaScript code won't let me execute a server-side php function
(obviously).
And I don't want to just shoot the link off to another page (even though
that's what it was designed to do). I want to call a very specific
function.
Tricky, I know. :(
