OK, here's a little update for people using later versions of vBulletin such as myself [I'm using 2.2.5].
Firstly the following code found in step one [as shown below]...
if ($wordwrap!=0) {
$threadinfo[title]=dowordwrap($threadinfo[title]);
}
eval("dooutput(\"".gettemplate("sendtofriend")."\");");
...is different, and actually looks like this...
if ($wordwrap!=0) {
$threadinfo[title]=dowordwrap($threadinfo[title]);
}
eval("dooutput(\"".gettemplate("sendtofriend")."\");");
...and you need to replace it with this...
if ($wordwrap!=0) {
$foruminfo[title]=dowordwrap($foruminfo[title]);
}
eval("dooutput(\"".gettemplate("sendtofriendforum")."\");");
You'll also have to use this template rather than the one FireFly posted or you'll have extra HTML showing at the top of the page. So insert this into a new template called sendtofriendforum...
{htmldoctype}
<html>
<head><title>$bbtitle :: Send Page to a Friend</title>
$headinclude
</head>
<body>
$header
<form action="sendtofriendforum.php" method="post">
<input type="hidden" name="s" value="$session[sessionhash]"><input type="hidden" name="forumid" value="$forumid">
<table cellpadding="{tableouterborderwidth}" cellspacing="0" border="0" bgcolor="{tablebordercolor}" {tableouterextra} width="{contenttablewidth}" align="center"><tr><td>
<table cellpadding="4" cellspacing="{tableinnerborderwidth}" border="0" {tableinnerextra} width="100%">
<tr>
<td bgcolor="{tableheadbgcolor}" colspan="2"><normalfont color="{tableheadtextcolor}" class="thtcolor"><b>Send This Page To A Friend</b></normalfont></td>
</tr>
$logincode
<tr>
<td bgcolor="{secondaltcolor}"><normalfont><b>Send To (Person's Name):</b></normalfont></td>
<td bgcolor="{secondaltcolor}"><normalfont><input type="text" class="bginput" name="sendtoname" size="25" maxlength="75"></normalfont></td>
</tr>
<tr>
<td bgcolor="{firstaltcolor}"><normalfont><b>Send To (Email Address):</b></normalfont></td>
<td bgcolor="{firstaltcolor}"><normalfont><input type="text" class="bginput" name="sendtoemail" size="25" maxlength="100"></normalfont></td>
</tr>
<tr>
<td bgcolor="{secondaltcolor}"><normalfont><b>Subject:</b></normalfont></td>
<td bgcolor="{secondaltcolor}"><normalfont><input type="text" class="bginput" name="emailsubject" value="$threadinfo[title]" size="25" maxlength="100"></normalfont></td>
</tr>
<tr>
<td bgcolor="{firstaltcolor}" valign="top"><normalfont><b>Message:</b></normalfont></td>
<td bgcolor="{firstaltcolor}"><textarea name="emailmessage" rows="10" cols="50">I thought you might be interested in reading this web page:
$bburl/forumdisplay.php?forumid=$forumid&referrerid=$bbuserinfo[userid]
From,
$bbuserinfo[username]
</textarea></td>
</tr>
</table>
</td></tr></table>
<br>
<table cellpadding="2" cellspacing="0" border="0" width="{contenttablewidth}" {tableinvisibleextra} align="center">
<tr>
<td align="center"><normalfont>
<input type="submit" class="bginput" name="submit" value="Send Email Now!" accesskey="s">
<input type="hidden" name="threadid" value="$threadid">
<input type="hidden" name="action" value="sendfriend">
</normalfont></td>
</tr>
</table>
</form>
$footer
</body>
</html>
...and finally, an extra step; edit your existing template called redirect_sentemail and replace it with the following - this changes the word Thread to Page, so it applies to threads and forums, and is also slightly more explanatory.
We have sent your email to $sendtoname. You will now be returned to the page that you sent to your friend.
Hope this might have helped some of you, and thanks again to FireFly for the hack! :)
