我想顯示一些變量和形式像收件箱類型的消息與「回聲」。「回聲」未顯示在php
問題是回顯不顯示，不知道如何修復它。
當我點擊主題標題上的主題字段應顯示「回聲」，但它沒有。
貝婁是代碼：
<?php
if(isset($_GET['msg_id'])){
$get_id = $_GET['msg_id'];
$sel_message = "select * from messages where msg_id='$get_id'";
$run_message = mysqli_query($con, $sel_message);
$row_message = mysqli_fetch_array($run_message);
$msg_subject = $row_message['msg_sub'];
$msg_topic = $row_message['msg_topic'];
$reply_content = $row_message['reply'];
//updating the unread message to read
$update_unread = "update messages set status='read' where msg_id='$get_id'";
$run_unread = mysqli_query($con, $update_unread);
echo "
<center><br />
<hr>
<h2>$msg_subject</h2><br/>
<p><b>Message:</b>$msg_topic</p><br />
<p><b>My reply:</b>$reply_content</p><br/>
<form action='' method='post'>
<textarea cols='60' rows='10' name='reply'></textarea><br /><br />
<input type='submit' name='msg_reply' value='Reply to this' />
</form>
</center>
";
}
if(isset($_POST['msg_reply'])){
$user_reply = $_POST['reply'];
if($reply_content!='no_reply'){
echo "<h2 align='center'>This message was already replied!</h2>";
exit();
} else {
$update_msg = "update messages set reply='$user_reply' where msg_id='$get_id'";
$run_update = mysqli_query($con, $update_msg);
echo "<h2 align='center'>Message was replied!</h2>";
}
}
}
?>
貝婁是從my_messages.php的所有代碼。我決定把它放在這裏所有的代碼，以避免任何有關缺少代碼信息的問題。也許會有助於獲得錯誤。
問題出在代碼結束時，當我點擊我的收件箱，並且當我點擊發件人主題時郵件沒有顯示。該窗體不顯示回顯功能。

你是說你的回聲沒有顯示任何東西？ – Erick
是的！什麼也沒有 –
我認爲這只是你的代碼的一部分？因爲否則它是非常合乎邏輯的，它不會起作用。 – icecub
