Plugins - how toi print out content, and stop "1" showing at bottom of page?

Hi,

I'm trying to write something that works with:

gforum.cgi?action=guestbook

Now, this works fine:

Code:
sub main { 
# ----------------------------------------------------------------------------- 
# This subroutine will be called whenever the hook 'main' is run.  You 
# should call GT::Plugins->action(STOP) if you don't want the regular 
# 'main' code to run, otherwise the code will continue as normal. 
# 
    my (@args) = @_; 

# Do something useful here 
    if ($IN->param('action') eq "guestbook") { 

      use GForum::Template; 

      my $do = $IN->param('do'); 
      if (!$do) {  
         print $IN->header(); 
         print GForum::Template->parse_print('error.html',  { error => "FOO" } ); 
         exit; 
      }  
      GT::Plugins->action(STOP); 
    } 


    return @args; 
}

(the error.html bit is just to test the GForum::Template parsing bits :))

However, at the bottom of the page it shows:

Quote:

I've attached a screenshot.

I've also tried:

Code:
sub main { 
# ----------------------------------------------------------------------------- 
# This subroutine will be called whenever the hook 'main' is run.  You 
# should call GT::Plugins->action(STOP) if you don't want the regular 
# 'main' code to run, otherwise the code will continue as normal. 
# 
    my (@args) = @_; 

# Do something useful here 
    if ($IN->param('action') eq "guestbook") { 

      use GForum::Template; 

      my $do = $IN->param('do'); 
      if (!$do) {  
         print $IN->header(); 
         return GForum::Template->parse_print('error.html',  { error => "FOO" } ); 
      }  
      GT::Plugins->action(STOP); 
    } 


    return @args; 
}

..but that prints out error.html, and then shows the normal page Pirate

Whats the correct way for printing out in GForum? I remember doing some stuff with PMManager back in 2004 - but all I can see in there, is stuff like:

return GForum::Template->parse_print('pmmanager_folder_page_sent.html', { pm_list => \@pms, %$vars } );

..and somehow, that seems to work right - so I'm not sure what I'm doing wrong :(

TIA for any suggestions .. in the mean time, I'll keep playing here =)

Cheers

Hi,

Anyone? GT?

This works fine: (Shows without a 1);

Code:
sub main { 
# ----------------------------------------------------------------------------- 
# This subroutine will be called whenever the hook 'main' is run.  You 
# should call GT::Plugins->action(STOP) if you don't want the regular 
# 'main' code to run, otherwise the code will continue as normal. 
# 
    my (@args) = @_; 

# Do something useful here 
    use GForum::Template; 

    my $do = $IN->param('func'); 
    if ($do eq "view") { 
         view_guestbook();   
    } else { 
         print $IN->header(); 
         return ('error.html',  { error => "Invalid function called" } ); 
         exit; 
    } 

    return @args; 
}

.. yet if (for example) in view_guestbook(), I have this:

Code:
sub view_guestbook { 

         print $IN->header(); 
         return ('error.html',  { error => "Invalid function called" } ); 
         exit; 

}

..I get this error:

Quote:

Software error:

GT::Template::Parser (4871): Unable to locate template file 'Plugins::GForum::Guestbook' in '/var/home/linkssql/ultradev.com/cgi-bin/forum/admin/templates/default/../common' or any inheritance directories at GT::Template::_compile_template line 677.

For help, please send mail to the webmaster ([no address given]), giving this error message and the time and date of the error.

Can someone **PLEASE** shed some light on this - its really beginning to get on my nerves, as this plugin is almost ready to release - but cos of this silly "1" showing up, its still faulty Pirate

TIA

As a programmer I'm surprised you don't know the reason for a "1" showing at the bottom of your page.

I would guess the reason for two pages displaying is that you have:

GT::Plugins->action(STOP);

....in the wrong place (i.e. AFTER you have already returned instead of before, so it never gets called).

As for the "1", it's probably because you are printing a print.....

print GForum::Template->parse_print('error.html', { error => "FOO" } );

Try:

GForum::Template->parse_print('error.html', { error => "FOO" } );

Normally, it means it getting a "return" of TRUE (i.e the 1) .. but I didn't think that was the case in this.

Ya, that was a silly one =) Its not needed anyway, as the way this plugin uses "actions", so its not actually calling a plugin hook , which is why that function call would normally be use Smile

print GForum::Template->parse_print('error.html', { error => "FOO" } );

OMG - you're a star!!!! Works a charm. I can't believe it was so simple.

I tried so many different ways (print, return GT::Template, return 'template', {vars}, and more) - and all it needed was the print taken out.

Thanks again - thats really made my day Smile

(not sure why GT couldn't have given some advise too :/)
