Re: [mv] [if explicit][condition] troubles

******    message to minivend-users from Jonathan <jrs@abhost.net>     ******

I've managed to get minivend to do what I want it to do with the userdb
but for some reason the checkout page is being displayed instead of the
mv_nextpage.  If anyone can show me what I can do so that the
mv_nextpage gets displayed instead of the ord/checkout I'd be thankful.

(ideally what I'd like to do is have the mv_nextpage set to the current
page that the user is viewing... but for now I'll be happy with
mv_nextpage being the root of my minivend site.)

I haven't figured out why any of the test examples below don't work but
I've been able to do this instead:

[set name="logged_in" interpolate=1][perl interpolate=1]
  my $username = '[value mv_username]';
  if ($username eq 'guest' || $username eq '') { return 0; }
  else { return 1; }
[/perl][/set]

[if scratch logged_in]
[include pages/special/logout.html]
[else]
[include pages/special/login.html]
[/else]
[/if]

key parts of the login.html look like:

<form action="[process-target]" method="post">
<input type="hidden" name="mv_click" value="Login">
<input type="hidden" name="mv_doit" value="return">
<input type="hidden" name="mv_nextpage" value="/">
<input type="text" name="mv_username" value="">
<input type="password" name="mv_password" value="">
<input type="submit" value="Log in"></font></td>
</form>

key parts of the logout.html look like:

<form action="[process-target]" method="post">
<input type="hidden" name="mv_click" value="Login">
<input type="hidden" name="mv_doit"  value="return">
<input type="hidden" name="mv_nextpage" value="/">
<input type="hidden" name="mv_username" value="guest">
<input type="hidden" name="mv_password" value="no_password">
<input type="hidden" name="mv_verify" value="no_password">
<input type="hidden" name="mv_cookie_password" value="1">
</form>

any help would be welcome.

thanks a lot.
