Interesting. This gives me some ideas. I'm also happy to know I wasn't
too far off :-
Thanks,

RE: [PHP] How would you write this?
Hi...
the easiest way I have found to do exactly what your looking for is to use a
pear package called html_quickform. I found it easy to use and it saves me
hours and hours of work too. If your interested go to
www.pear.php.net/html_quickform and have a look.

The following code works but I'm a little new to PHP and I'd like to
know if there are better ways to achive the same thing.
In the below form example, if the user supplies one or more fields but
not all that are required, the form is redisplayed but fields that were
supplied are prepopulated and the ones that are required but are missing
are highlighted in red.
Can anyone recommend a better technique or elighten me about features of

Re: [PHP] How would you write this?
I personally would use javascript to evaluate the form and highlight the
fields onsubmit.
However as a backup I'd do the evaluating in php and add an error label under
the field.
echo td;
if ($noPass) echo color='red';
echo Password/td;
if ($noPass) echo td color='red'You must supply a password/td;
Something along those lines.
