Question

任何人都可以向我解释为什么我会收到重复邮件而不是邮件吗？如何更改我的代码，以便在我键入注释并按“注释”按钮时，它只显示一条消息而不是重复消息！当我有一个评论框时，它不显示重复的评论，但如果我有多个评论，那么它开始重复！

COMMENT.INC.PHP

include 'cdbh.inc.php';
function setComments($con) 
{
    if (isset($_POST['commentSubmit'])) {
        $uid = mysqli_real_escape_string($con,$_POST['uid']);
        $date = mysqli_real_escape_string($con,$_POST['date']);
        $message =  mysqli_real_escape_string($con,$_POST['message']);

        $sql = "INSERT INTO comments (uid, date, message) VALUES ('$uid','$date','$message')";
        $result = mysqli_query($con,$sql);
    }
}

function getComments($con)
{
    $sql = "SELECT * FROM comments";
    $result = mysqli_query($con,$sql);
    while ($row=mysqli_fetch_assoc($result)) {
        echo $row['uid'];
        echo ":"; 
        echo $row['message']."<br><br>";
    }
}

    date_default_timezone_set('America/Los_Angeles');  
    include 'comment.inc.php';
    include("connection.php");
?>

            $result=mysqli_query($connection,$sql);
            while ($row=mysqli_fetch_array($result)) {
        ?>
        <img src="images/<?php echo $row['images_name'] ?>" width="200px" height="200px">
        <?php
            echo "<form method ='POST' action ='".setComments($con)."'>
                    <input type ='hidden' name ='uid' value='unknown'>
                    <input type ='hidden' name ='date' value='".date('Y-m-d H:i:s')."'>
                    <textarea name='message'></textarea>
                    <button type ='submit' name='commentSubmit'>Comment</button>
                </form>";
            }
            getComments($con);
        ?>
    </body>
</html>

也许您正在提交所有表单而不是一个表格。检查你的数据库，以了解img来自每条消息。如果你有其他代码，比如javascript，你应该发布它。
