我這裏加入了particles-js的粒子特效，效果以下（用table作這個有bug，之後仍是不用table+form了）html
是有動態效果的，很炫酷，因爲動態圖可能有bug，這裏我上傳的.pngmysql

聊天室（留言分爲了三類，建議，反饋，投訴，三類分別有對應的php後臺處理）dom
注：因爲是後面才加的分類，因此對沒有修改之前直接提交的form表單post
先是判斷是否登陸:
1 <?php 2 if (!$_SESSION['uid']) 3 { 4 die('<script>alert("未登陸，請登陸");window.location.href = "sign_in.php";</script>'); 5 } 6 ?>
