网页上看不到编辑按钮。不知道为什么？工作，我只添加[$ eventid]部分。删除它，它仍然无法正常工作。尝试使用其他浏览器但仍无法正常工作。

    <div class="current events">
        <h1>Your Current Events:</h1>
        <?php

        $sql = "SELECT * FROM events WHERE userid='{$_SESSION['u_id']}';";
        $result = mysqli_query($conn, $sql);
        if (mysqli_num_rows($result) > 0){
            while ($row = mysqli_fetch_assoc($result)){
                echo "<b>Event name: </b>";
                echo " ";
                echo $row['eventname'];
                echo " ";
                echo "<b>Event Venue: </b>";
                echo " ";
                echo $row['venue'];
                echo " ";
                echo "<b>Event Date: </b>";
                echo " ";
                echo $row['date'];
                echo "<p></p>";


                "

            }

Answer 1

您忘了echo表单内容。因为它在php中你必须echo

 echo "
                    <form class='edit-btn' method='POST' action='editevent.php'>
                        <input type='hidden' name='eventname' value='" .$row['eventname']. "'>
                        <input type='hidden' name='venue' value='" .$row['venue']. "'>
                        <input type='hidden' name='date' value='" .$row['date']. "'>
                        <input type='hidden' name='name' value='" .$row['name']. "'>
                        <input type='hidden' name='eventid' value='" .$row['eventid']. "'>

                        <button>Edit</button>

                    </form>


                ";

首先，在用双引号声明表单之前，包括“echo”。对于按钮的情况，您可以尝试使用输入。喜欢，。希望它能奏效。
