我創建了一個喜歡和不喜歡按鈕，但是當我點擊喜歡它喜歡我所有的帖子，這裏是我的代碼：按鈕喜歡一個崗位居然喜歡的所有帖子
$sql_posts = mysql_query("SELECT * FROM post WHERE mem_id='$id' ORDER BY post_date DESC LIMIT 30");
while($row = mysql_fetch_array($sql_posts)){
$postid = $row["id"];
$poster_id = $row["mem_id"];
$post_body = $row["post_body"];
$notokinarray = array("fucker", "ass", "shit", "fuck", "fucking", "damn", "asshole", "cunt", "damnit");
$okinarray = array("******", "***", "****", "****", "*******", "****", "*******", "****", "******");
$post_body = str_replace($notokinarray, $okinarray, $post_body);
$post_body = ($activeLinkObject -> makeActiveLink($post_body));
$post_date = $row["post_date"];
$convertedTime = ($myObject -> convert_datetime($post_date));
$whenPost = ($myObject -> makeAgo($convertedTime));
$device = $row["device"];
$postlikes = $row["likes"];
$postlikers = $row["likers"];
$postdislikes = $row["dislikes"];
$postdislikers = $row["dislikers"];
像功能（這是那裏的問題似乎是）

不錯的bug，通過哪來的方式 – marcio
'$ postid'得到第二片段設置？ –
$ postid被宣佈更遠，那個代碼我實際上忘記了，感謝評論 –
