Signature Image System

Signature Image System v1.0

Firstly if you use profile pictures on your forum, this hack isn't for you. Basicly this hack uses the user profile picture option in vB3 to upload an image for users to use in there signature on your site only.

This has been tested on vB3 Gamma, but should work on the RC's too.

Upload signature.php to your forums directory and make the following changes:

in includes/functions_showthread.php find:

PHP Code:

$post['signature'] = parse_bbcode($post['signature'], 'nonforum', $vboptions['allowsmilies']); 


Add after:

PHP Code:

                // EDIT ########################################################################
                // replace sig img code
                if ($vboptions['profilepicenabled'] AND ($checkperms['genericpermissions'] & CANPROFILEPIC)) {
                    $post['signature'] = preg_replace('/\[signatureimage\]/i', fetch_signature_url($post['userid']), $post['signature']);
                } 


In profile.php find:

PHP Code:

$previewmessage = parse_bbcode2($signature, $vboptions['allowhtml'], $vboptions['allowbbimagecode'], $vboptions['allowsmilies'], $vboptions['allowbbcode']); 


Add after:

PHP Code:

        // EDIT ########################################################################
        // do sig image
        if ($vboptions['profilepicenabled'] AND ($permissions['genericpermissions'] & CANPROFILEPIC)) {
            $previewmessage = preg_replace('/\[signatureimage\]/i', fetch_signature_url($bbuserinfo['userid']), $previewmessage);
        } 


In member.php find:

PHP Code:

$userinfo['signature'] = parse_bbcode($userinfo['signature'], 0, 0); 


Add after:

PHP Code:

$previewmessage = preg_replace('/\[signatureimage\]/i', fetch_signature_url($userinfo['userid']), $previewmessage); 


In includes/functions.php add the end somewhere above the comment (note the comment varies for everyone:

PHP Code:

/*======================================================================*\
|| ####################################################################
|| # Downloaded: 03:57, Fri Dec 5th 2003
|| # CVS: $RCSfile: functions.php,v $ - $Revision: 1.901 $
|| ####################################################################
\*======================================================================*/
?> 


Add:

PHP Code:

function fetch_signature_url($userid) {

                global $_SERVER;

    return '<img src="signature.php?userid='.$userid.'&amp;sig='.(TIMENOW + 30).'&amp;req='.md5('http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']).'" border="0" />';
} 


In the MEMBERINFO template find:

<if condition="$show['profilepic']">

Replace with:

<if condition="$show['profilepic'] AND $never_show_this">

Now you will need to visit the edit profile picture page in the User CP (profile.php?do=editprofilepic) and edit the phrases in the phrase manager to suit your needs. Searching for the text is easy so I'm not going to list all the phrases.

Now users can use [signatureimage] in there signature where they want the uploaded image to appear. Note you'll need to edit the usergroups permissions for Profile Pictures in the Usergroup Manager, where you can specify image size and file size restrictions.

no one tired this on vb3 gold as yet

is hard to believe vb3 does`nt have a decent sig uploader already built into it

[lasto]

Dont work on Gold

I also get the red X when i use the [signatureimage] in me sig box

[msimplay]

i would try it but i like the idea of profile pictures

[lasto]

just re-tried this on another copy of vb3 gold and im still getting the red x where the sig should be

Whats the URL for the image? Note that the URL changes every request and that your browser must send the HTTP_REFERER variable and the referrer in the URL must match this and that it must be within ~60 of the URL being generated.

If you comment out lines 43-46 in signature.php and the image shows then thats the problem.

Works flawlessly for me on both 3.0.0 Gamma and 3.0.0.

[lasto]

still red x even if i comment out the lines in signature php

not sure why cause all i do is load the pic up using the profile page link - i can see it but it dont appear in my posts.

/forums/signature.php?userid=1&sig=1081439840&req=afe5abd7 e1bbc945ccb8c852b528df1c

Exactly the same problem as lasto :

/image.php?u=1&type=profile&dateline=1081789262
/signature.php?userid=1&sig=1081789909&req=a7274137 a1de6ef2e61114224ea68c0e

Still have the red X... what to do ?

Nice hack... when it works ! Thanks anyway.

i've created a .txt for this hack that includes the phrase edits (there's 6 of them) and a USERCP_SHELL edit as well (to move the signature image link up to just under the signature edit link).

hope it helps some ppl.

as for me, i'm on 3.0.1, and i get the dreaded redX with this. i do feel, however, that it's a great hack for ppl not interested in profile pics. hopefully someone will be able to correct the redX problem for those of us currently experiancing it.

additionally, if somehow the [signatureimage] could be auto added to the signature, so that it was a one step deal (i.e. you upload a sig image, it's placed in your signature automatically) that would be awesome.

hope this one gets ironed out!

Try removing the following if block from signature.php:

PHP Code:

// check the request is from a valid referer, if not send a 404 header
if (TIMENOW > $_REQUEST['sig'] || ($_REQUEST['sig'] > (TIMENOW + 30)) || $_REQUEST['req'] !== md5($_SERVER['HTTP_REFERER'])) {
    header('HTTP/1.1 404 Not Found');
    exit;
} 


Thats the part that checks if the image is allowed to be shown or not. Note that this will enable hotlinking etc unless you add other measures to protect against it.

I still commented this part but always get the redX...
