我在使用这段代码时遇到了错误。我是 Bootstrap 和使用模态的新手。我过去常常为我所有的“花式”表格运行子表格，但现在我正在转向模态。这是我获取模态的代码:

<button class="btn btn-primary" data-toggle="modal" data-target="#newmemberModal">Add new Member</button>

<br />
<br />

<?php
    $result = mysql_query("SELECT * FROM `players` ORDER BY `players`.`user` ASC") 
        or die(mysql_error());  

    echo " <div class='table-responsive'><table class='table'>";
    echo "<tr><th>Username</th> <th>Rank</th> <th>Position</th> <th>DoP</th> <th>Tag</th> <th>AiT</th> <th>Service Stripes</th> <th>Notes</th> <th></th> <th></th><th></th></tr>";
    while($row = mysql_fetch_array( $result )) {

        echo "<tr>";
        echo '<td>' . $row['user'] . '</td>';
        echo '<td>' . $row['rank'] . '</td>';
        echo '<td>' . $row['position'] . '</td>';
        echo '<td>' . $row['date'] . '</td>';
        echo '<td>' . $row['tag'] . '</td>';
        echo '<td>' . $row['ait'] . '</td>';
        echo '<td>' . $row['ss'] . '</td>';
        echo '<td>' . $row['notes'] . '</td>';
        echo '<td><button class="btn btn-default" data-toggle="modal" data-target="#editModal">Edit</button></td>';
        echo '<td><a href="classes/forms/delete.php?id=' . $row['id'] . '">Delete</a></td>';
        echo '<td><a href="javascript:void(0);" NAME="My Window Name" title=" My title here " onClick=window.open("dd.php?id=' . $row['id'] . '","Ratting","width=350,height=550,0,status=0,");>DD</a><BR /><a href="javascript:void(0);" NAME="My Window Name" title=" My title here " onClick=window.open("hd.php?id=' . $row['id'] . '","Ratting","width=350,height=550,0,status=0,");>HD</a></td>';
        echo "</tr>"; 
    } 
    echo "</table> </div>";

?>

这是我的 edit.php:

问题是我一直收到“错误!”模态框中的消息，而不是其他任何内容。我试图做的目标是让它从存储在我的数据库中的 ID 中提取数据。我认为问题确实在于当我点击用户编辑时它没有获取 ID。坦率地说，我不知道如何通过模式编辑 ID。帮助将不胜感激。谢谢

奖励:我无法在同一页面上打开两个模式。如果我在同一页面上有两个，它们都不会显示:

<!--Modals-->

        </div>
    </div>
</div>

最佳答案

您的编辑按钮没有将 ID 传递给 edit.php，这就是未激活模态的原因。您需要在打开编辑模式之前而不是在加载它时填充编辑模式的内容。使用 include 将加载编辑页面而不向其传递 ID。

重写您的编辑按钮以包含 ID

<button class="btn btn-primary" data-toggle="modal" 
data-target="#editModal" data-formid="<?php echo $id; ?>">
    Edit <?php echo $id; ?>
</button>

打开模式时加载编辑表单的JS

//jQuery function for loading data 
$("#editModal").on('show.bs.modal', function(event){
    var button = $(event.relatedTarget);
    //bootstrap way of retrieving data-* attributes
    //data-formid in this case
    var id = button.data('formid');
    $.get(yourSiteUrl+'/classes/forms/edit.php?id='+id, 
    function(data) {
        $("#editModal .modal-title").html(data);
        //Resize the modal to the size of the loaded form.
        $("#editModal").modal("handleUpdate");
    });
});
