我已经构建了非常简单的消息传递系统,但是我有一点问题。 当向表中插入新消息时,我将该消息与发送它的用户名相关联,并且当发送消息的用户删除该消息时,该消息也将从接收者中删除。
我希望只从发件人中删除邮件。我更新表并在执行实际删除之前将消息首先设置为deleted = 'yes'
。有人能暗示我一个想法吗?
表格结构
id,from_user,to_user,subject,message,deleted,sent,date
$delete =$mysqli prepare("update messages set deleted = 'yes' where from_user = ? and id = ? ");
$delete->bind_param('ss', $username->username, $id);
foreach ($_POST['id'] as $id) {
$delete->execute();
实际删除...
$stmt = $mysqli->prepare("DELETE FROM messages where from_user = ? and id = ? or to_user = ? and id = ?");
$stmt->bind_param('ssss', $username->username, $id, $username->username, $id);
foreach ($_POST['id'] as $id) {
$stmt->execute();
答案 0 :(得分:0)
简单的想法:p
需要的表格:
id,content,lastmodified_time
id,UserId,MessageId,DeliveryType,Deleted
即:
<强>消息:强>
1,Test Message,2013-10-31 00:00:00
<强> MessageUser 强>
1,11999,1,'外向',0
2,12585,1,'传入',1
