Question

我有一个表格，其中有一个“编辑”和“删除”按钮，问题是我正在使用模式，一旦在其中一行上单击“编辑”按钮，模式就不会出现，而只会出现在表格的第一行我的桌子...我的代码中缺少什么？

这是我的编辑模式代码

  <!-- Modal for Edit button for News -->
<div class="modal fade" id="EDITnews<?php echo $news_id;?>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">

                <div class="modal-body">
                <div class="container-fluid">

您需要遍历结果：

                        <?php
                            $conn = mysqli_connect('localhost', 'root', '', 'testdb');
                            $sql = mysqli_query($conn,"SELECT * FROM news WHERE news_id = '$news_id' ");
                            while($sqrow = mysqli_fetch_assoc($sql)){
$news_id = $sqrow["$news_id"];
                        ?>

        <div class="modal fade" id="EDITnews<?php echo $news_id;?>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
            <div class="modal-dialog">
                    <div class="modal-content">
                        <div class="modal-header">
                            <h4 class="modal-title" id="myModalLabel">News</h4>
                        </div>
                        <div class="modal-body">
                        <div class="container-fluid">
                        <form method="POST" action="#" enctype="multipart/form-data">

                             <label><b>News Description:</b></label>
                             <input class="form-control" type="text" value="<?php echo $sqrow['news']; ?>" name="news" required>
                             <label><b>Date:</b></label>
                                      <input class="form-control" type="date" value="<?php echo $sqrow['news_date']; ?>" name="newsDate" required>
                             <label><b>Time:</b></label>
                                      <input class="form-control" type="time" value="<?php echo $sqrow['news_time']; ?>" name="newsTime" required><br> 
                                      <button type="submit" name="addEvent" class="btn btn-primary"><i class="fa fa-save"></i> Save Changes</button>
                        </form>                   
                        </div>
                    </div>
                </div>
            </div>
        </div>

    <?php  
    }
    ?>

我在使用php进行模态时遇到麻烦
