Howto: make each user's signature only appear once per page

jamesinc

This is quite a simple change for the Signatures plugin:

Find the _DrawSignature function.

The last statement in the function should be:

echo $Display;

Add two lines above that:

// Ensure sig only renders once for each user
unset($UserSignatures[$SourceUserID]);
$Sender->SetData('Plugin-Signatures-UserSignatures', $UserSignatures);

This will unset the user's signature from the signature cache after the first time it is rendered on the page.

Hope someone finds it useful!

@jamesinc, I did almost the exact same thing for my community.

Nice!

Hi @jamesinc. Please, give more detailes. Should we add:

        // Ensure sig only renders once for each user
        unset($UserSignatures[$SourceUserID]);
          $Sender->SetData('Plugin-Signatures-UserSignatures', $UserSignatures);
    echo $Display;

Right? In what file? In what place?

Thanks in advance!

Hi @mirX, sorry for the lateness of my reply!

This is what my plugins/Signatures/class.signatures.plugin.php looks like, starting at line 283:

         // Ensure sig only renders once for each user
         unset($UserSignatures[$SourceUserID]);
         $Sender->SetData('Plugin-Signatures-UserSignatures', $UserSignatures);

         echo $Display;

In case there is any ambiguity, I have zipped the version of Signatures I am currently using in production (1.1.5)

I have updated this for 1.5.6

In class.signatures.plugin.php, find the following (line 346):

if (!is_null($RequestUserID)) 
   return GetValue($RequestUserID, $Signatures, $Default);

And replace it with:

if (!is_null($RequestUserID)) {
   $Sig = GetValue($RequestUserID, $Signatures, $Default);
   unset($Signatures[$RequestUserID]);

   return $Sig;
}

Another way of doing it is to only show the signature when you hover over the post, with a little bit of jquery.

Thanks @jamesinc for assistance!

Your amendment to version 1.5.6 works fine!

Thanks @x00 for good idea. What do you think is it possible to show the signature along with small Sharethis buttons when you hover over the post?
