Question

有人可以帮我解决我在我的个人资料中有用户消息，它只显示最后一条消息，我将如何显示该用户的所有消息。

以下是我已经拥有的代码：

<?php 
    $message_list = mysql_query("SELECT * FROM `messages`");
    while($get_message = mysql_fetch_array($message_list)) {
        $message_subject = $get_message['subject'];
        $message_body    = $get_message['body'];
        $message_from    = $get_message['from_user'];
        $message_date    = $get_message['date'];
        $message_to      = $get_message['to_user'];
        }
        if($message_to === $user_data['username']) {


                echo 
                '
                <center>
                <table border="2" bordercolor="" style="background-color:" width="85%" cellpadding="3" cellspacing="3">
                        <tr>
                            <td width="15%"><center>From</center></td>
                            <td width="20%"><center>Date / Time</center></td>
                            <td><center>Message</center></td>
                            <td width="15%"><center>Reply</center></td>
                            <td width="7%"><center>Delete</center></td>
                        </tr>
                </table>
                </center>';
                echo 
                '
                <center>
                <table border="1" bordercolor="" style="background-color:" width="85%" height="35px" cellpadding="3" cellspacing="3">
                        <tr>
                            <td width="15%"><center>'. $message_from .'</center></td>
                            <td width="20%"><center>'. $message_date .'</center></td>
                            <td><center><br>'. $message_body .'<br></center><br></td>
                            <td width="15%"><center>Reply</center></td>
                            <td width="7%"><center><form><input type="checkbox" name="delete"></form></center></td>
                        </tr>
                </table>
                </center>';
        } else {
            echo '<center>you have no messages</center>';
        }
    ?>

所有显示的内容都是最后输入的消息。

问题是你早点结束循环，试试这个代码而不是你的代码

    <?php 
        $message_list = mysql_query("SELECT * FROM `messages`");
        while($get_message = mysql_fetch_array($message_list)) {
            $message_subject = $get_message['subject'];
            $message_body    = $get_message['body'];
            $message_from    = $get_message['from_user'];
            $message_date    = $get_message['date'];
            $message_to      = $get_message['to_user'];

            if($message_to === $user_data['username']) {


                    echo 
                    '
                    <center>
                    <table border="2" bordercolor="" style="background-color:" width="85%" cellpadding="3" cellspacing="3">
                            <tr>
                                <td width="15%"><center>From</center></td>
                                <td width="20%"><center>Date / Time</center></td>
                                <td><center>Message</center></td>
                                <td width="15%"><center>Reply</center></td>
                                <td width="7%"><center>Delete</center></td>
                            </tr>
                    </table>
                    </center>';
                    echo 
                    '
                    <center>
                    <table border="1" bordercolor="" style="background-color:" width="85%" height="35px" cellpadding="3" cellspacing="3">
                            <tr>
                                <td width="15%"><center>'. $message_from .'</center></td>
                                <td width="20%"><center>'. $message_date .'</center></td>
                                <td><center><br>'. $message_body .'<br></center><br></td>
                                <td width="15%"><center>Reply</center></td>
                                <td width="7%"><center><form><input type="checkbox" name="delete"></form></center></td>
                            </tr>
                    </table>
                    </center>';
            } else {
                echo '<center>you have no messages</center>';
            }
}
        ?>

只需要移动一个支架就可以了！

<?php 
$message_list = mysql_query("SELECT * FROM `messages`");
while($get_message = mysql_fetch_array($message_list)) {
    $message_subject = $get_message['subject'];
    $message_body    = $get_message['body'];
    $message_from    = $get_message['from_user'];
    $message_date    = $get_message['date'];
    $message_to      = $get_message['to_user'];
    //DELETED BRACKET HERE
    if($message_to === $user_data['username']) {


            echo 
            '
            <center>
            <table border="2" bordercolor="" style="background-color:" width="85%" cellpadding="3" cellspacing="3">
                    <tr>
                        <td width="15%"><center>From</center></td>
                        <td width="20%"><center>Date / Time</center></td>
                        <td><center>Message</center></td>
                        <td width="15%"><center>Reply</center></td>
                        <td width="7%"><center>Delete</center></td>
                    </tr>
            </table>
            </center>';
            echo 
            '
            <center>
            <table border="1" bordercolor="" style="background-color:" width="85%" height="35px" cellpadding="3" cellspacing="3">
                    <tr>
                        <td width="15%"><center>'. $message_from .'</center></td>
                        <td width="20%"><center>'. $message_date .'</center></td>
                        <td><center><br>'. $message_body .'<br></center><br></td>
                        <td width="15%"><center>Reply</center></td>
                        <td width="7%"><center><form><input type="checkbox" name="delete"></form></center></td>
                    </tr>
            </table>
            </center>';
    } else {
        echo '<center>you have no messages</center>';
    }

 } //PUT IT HERE
?>

但正如警告一样，这将输出＆＃34;你没有消息＆＃34;每次系统中都有消息，即使它不是用户！我只是将您的查询更改为包含基于用户数据的WHERE子句

    $username = $user_data['username'];
    $message_list = mysql_query("SELECT * FROM `messages` WHERE `to_user` = '$username'");

为什么只显示输入的最后一条消息
