# End就是回覆文章的時候，因為 Hide subject field on reply 外掛把主題名稱的輸入欄位給隱藏起來，
而強制使用主題類型外掛的 Java scipt 找不到 document.post.subject.value ，於是會跳出瀏覽器的錯誤碼。
沒辦法，我只好把強制使用主題類型外掛給拆掉，結果開始有網友發表主題的時候不加上主題類型.... Orz
後來想到一個解決方法，就是把強制使用主題類型改寫入 functions_post.php 內，
這樣只有網友在發表主題($mode == 'newtopic')的時候，系統才會去檢查有沒有加上主題類型。
如果是回覆文章的時候，系統不會去檢查有沒有加上主題類型，也就不會和 Hide subject field on reply 外掛相衝了。
我試過這樣修改：
代碼: 選擇全部
開啟 functions_post.php ，搜尋：
// Check message
上面加入：
if ($mode == 'newtopic' && $subject != '[')
{
$error_msg .= (!empty($error_msg)) ? '<br />' . $lang['Empty_subject_type'] : $lang['Empty_subject_type'];\r
}
開啟 lang_main.php ，加入：
$lang['Empty_subject_type'] = '發表主題必須選擇主題類型';如果有人知道要怎麼樣把強制使用主題類型改寫到 functions_post.php 內，煩請指教一下，謝謝。
