Although there is option in every module that would let you choose who can post a comment. But what if you want anonymous users to post comments as well. There isn't any option (at least I couldn't find any) that will prevent anonymous users from spamming. So this hack will prevent spam if a url\link is found in anonymous users' post.
As always recommended while playing with hacks, make sure you backup the file you will be editing. In this case its: XOOPS_ROOT_DIR\Include\comment_post.php
Note: I have tested it only on Xoops 2.0.16
Start...
1) Open XOOPS_ROOT_DIR\Include\comment_post.php
2) Look for the following on line 138
Original Code
break;
case "post":
$doimage = 1;
$comment_handler =& xoops_gethandler('comment');
$add_userpost = false;
$call_approvefunc = false;
$call_updatefunc = false;
3) Change it to ...
break;
case "post":
//myhack - Prevent Anonymous User Spam
//if a URLLINK is found in link, then dont let annonymous user post.
$myhack_comment = $_POST['com_text'];
$myhack_title = $_POST['com_title'];
//checking if poster is anonymous
if (!is_object($xoopsUser)) {
if (preg_match("/http/",$myhack_comment) || preg_match("/www/",$myhack_comment) || preg_match("/href/",$myhack_comment) || preg_match("/http/",$myhack_title) || preg_match("/www/",$myhack_title)) {
echo "Dont Spam Bitch!!!!!";
exit();
}
else {
}
}
//end of myhack
$doimage = 1;
$comment_handler =& xoops_gethandler('comment');
$add_userpost = false;
$call_approvefunc = false;
$call_updatefunc = false;
