這兒用到的一些變數, 在前文中有所描述, 請勿直接依照本文的內容修改, 而沒有依照前文的某些部份做修改, 否則... 那段程式碼可能會有問題.

首先, 修改 lang_main.php , 把之前所加上的那兩段語言定義修改一下, 原本為:

$lang['ANTISPAM_Check'] = '在註冊時請選擇此欄位';
$lang['ANTISPAM_Check_Error'] = '[在註冊時請選擇此欄位] 這個欄位未選擇';

改成:

$lang['ANTISPAM_Check'] = '請選擇此欄位';
$lang['ANTISPAM_Check_Error'] = '[請選擇此欄位] 這個欄位未選擇';

讓原本給註冊專用的訊息也能在這兒使用.

修改 posting_body.tpl, 找到下頭的字串:

		<td class="row2"><span class="genmed"><input type="text" class="post" tabindex="1" name="username" size="25" maxlength="25" value="{USERNAME}" /></span></td> 

改成:

		<td class="row2"><span class="genmed"><input type="text" class="post" tabindex="1" name="username" size="25" maxlength="25" value="{USERNAME}" />
<!-- add by twu2 20060919 begin -->
<input type="checkbox" name="check_{HCODE}" />{L_ANTISPAM_CHECK}
<!-- add by twu2 20060919 end -->
</span></td>

修改 posting.php, 找到下頭的字串:

 	'HCODE' => md5($userdata['username'] . $userdata['user_regdate']),
 	'HCODENAME' => md5($userdata['username'] . $hcode_date . ANTISPAM),
 	'DATE' => $hcode_date, 

在後頭加上一段, 變成:

 	'HCODE' => md5($userdata['username'] . $userdata['user_regdate']),
 	'HCODENAME' => md5($userdata['username'] . $hcode_date . ANTISPAM),
	'DATE' => $hcode_date,
	'L_ANTISPAM_CHECK' => $lang['ANTISPAM_Check'], 

找到下頭的字串:

 			if (!isset($hcode) || empty($hcode) || $hcode != $hcode_old) {
 				//debug_writelog("antispam for ".$userdata['user_id'].", ".$userdata['username']);
 				message_die(GENERAL_MESSAGE, $lang['ANTISPAM_Error']);
 			} 

在後頭加上一段, 變成:

 			if (!isset($hcode) || empty($hcode) || $hcode != $hcode_old) {
 				//debug_writelog("antispam for ".$userdata['user_id'].", ".$userdata['username']);
 				message_die(GENERAL_MESSAGE, $lang['ANTISPAM_Error']);
 			}

			if (($username != '' || $userdata['user_id'] == ANONYMOUS) &&
                	    !isset($HTTP_POST_VARS['check_'.$hcode]) ) {
				//debug_writelog("antispam 1 for ".$userdata['user_id'].", ".$username);
				$error_msg = $lang['ANTISPAM_Check_Error'];
			}
			else 

這樣子就可以在訪客發文時, 檢查是否有點選那個非一般 PHPBB 使用的欄位, 來避免那些專對 PHPBB 所寫的 bot 使用訪客的身份來發文了.

如果有使用 QuickReply 的模組, 還要修改下頭的檔案.

修改 viewtopic_body.tpl, 找到下面的字串:

      <span class='genmed'><input type='text' class='post' tabindex='1' name='username' size='25' maxlength='25' value='' /></span><br /> 

改成:

      <span class='genmed'><input type='text' class='post' tabindex='1' name='username' size='25' maxlength='25' value='' />
<!-- add by twu2 20060419 begin -->
<input type="checkbox" name="check_{HCODE}" />{L_ANTISPAM_CHECK}
<!-- add by twu2 20060419 end -->
</span><br /> 

修改 viewtopic.php, 找到下頭的字串:

         'HCODE' => md5($userdata['username'] . $userdata['user_regdate']),
         'HCODENAME' => md5($userdata['username'] . $hcode_date . ANTISPAM),
         'DATE' => $hcode_date, 

在後頭加上一段, 變成:

         'HCODE' => md5($userdata['username'] . $userdata['user_regdate']),
         'HCODENAME' => md5($userdata['username'] . $hcode_date . ANTISPAM),
         'DATE' => $hcode_date,
         'L_ANTISPAM_CHECK' => $lang['ANTISPAM_Check'], 

這樣子就可以了.
