Need help with plugin to allow only one thread in selected forums

[mark-in-dallas]

I am trying to make a plugin to prevent users from posting more than one thread in selected forums.  This should be pretty simple, but I'm not a very experienced programmer, and just can't seem get it right.  I think I'm pretty close, but just not quite there.

Any help would be appreciated.  Here's what I have:

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99

<?php if(!defined("IN_MYBB")) { die("Direct initialization of this file is not allowed.<br /><br />Please make sure IN_MYBB is defined."); } $plugins->add_hook("newthread_do_newthread_end", "limitthreadsinforums_addthread"); function limitthreadsinforums_info() { return array( "name" => "Limit to one thread in selected Forums", "description" => "Limits users from posting more than one thread in selected forums!", "website" => "http://websitesdallas.com", "author" => "mark-in-dallas", "authorsite" => "http://websitesdallas.com", "version" => "1.0", "guid" => "", "compatibility" => "1*", ); } function limitthreadsinforums_activate() { global $db; $limitthreadsinforums_group = array( "name" => "limitonethreadinforums", "title" => "Limit to one thread post in specified forums", "description" => "Limits users from posting more than one thread in specified forums", "disporder" => "2", "isdefault" => "no", ); $db->insert_query("settinggroups", $limitthreadsinforums_group); $gid = $db->insert_id(); $new_setting = array( 'name' => 'limitthreadsinforums', 'title' => 'Limit users to posting only one thread in specified forums. Separate FIDs with commas', 'description' => 'Forums to limit', 'optionscode' => 'text', 'value' => '', 'disporder' => '1', 'gid' => intval($gid) ); $db->insert_query('settings', $new_setting); rebuildsettings(); } function limitthreadsinforums_deactivate() { global $db; $db->query("DELETE FROM ".TABLE_PREFIX."settings WHERE name='limitthreadsinforums'"); $db->delete_query("settinggroups","name='limitonethreadinforum'"); rebuildsettings(); } function limitthreadsinforums_addthread() { global $new_thread, $mybb, $db, $fid; if (empty($new_thread['fid'])) return; if (empty($mybb->settings['fid'])) return; $limit = explode(",", $mybb->settings['fid']); $forum = $new_thread['fid']; if (in_array($forum,$limit)) $query = $db->simple_select("threads", "uid"); $uid = explode(",", $db->threads['uid']); $forum = $new_thread['fid']; if (in_array($forum,$uid)) { exit("You cannot post more than one thread in this forum"); } elseif (empty($new_thread['uid'])) return; } ?>
