Question

我今天早些时候问a question，简而言之，用户点击页面上的按钮时会出现一个弹出模式，它应该获得一个PHP变量值。

由于单击弹出模式btn时没有GET或POST请求，这意味着我无法使用上面两个选项获取变量值

尝试了以下内容：

`<a id="myid" data-id="<?php echo $userID ?>">link</a>
<script>
  $('#myid').data("id");
</script>`

现在我在javascript变量中有PHP $userID值。这引出了我的问题，检索$userID变量并将其插入php变量的最有效方法是什么。

其他信息

我found this question关于SO，但它并不适用于我。

                 $src = $teacher['userID'];

Answer 1

首先，从id="myId"移除<a></a>。 ID必须是唯一的。使用课程。

<强> First_Page.php

<?php
$teacherClass = new TeacherSearch();
$teachers = $teacherClass->showAllTeachers();
if (is_array($teachers)) {
  foreach ($teachers as $teacher) {
    $src = $teacher['userID'];
    ?>
    <div class="teacher-info">
      <p class="teacherLabel">
        NAME:<?php echo $teacher['name']; ?>
      </p>
      <p class="teacherLabel">
        HEADLINE:
        <?php echo $teacher['headline'];?>
      </p>
      <p class="teacherLabel">
        LOCATION: <?phpecho $teacher['location'];?>
      </p>
      <!--BUTTON GOES HERE-->
      <a class="openModal" data-id="<?php echo $teacher['userID'] ?>" data-toggle="modal" href="#myModal">
        Hire <?php echo $teacher['name']; ?>
      </a>
    </div>
  <?php }
}?>

在</body>代码结束前将代码放在页脚中。

<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">

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

<强> JS

<script>
  $('.openModal').click(function(){
      var id = $(this).attr('data-id');
      $.ajax({url:"modal_ajax.php?id="+id,cache:false,success:function(result){
          $(".modal-content").html(result);
      }});
  });
</script>

创建新文件 modal_ajax.php 。

[注意：请记住，此页面名称modal_ajax.php也用于脚本标记。如果您打算更改此页面的名称，请在脚本标记中更改页面名称。两者都是相关的。]

<div class="modal-header">
  <button type="button" class="close" data-dismiss="modal">&times;</button>
  <h4 id="modalTitle" class="modal-title"></h4>
</div>
<div class="modal-body">
  <?php echo "ID: ".$_GET['id'];?>
</div>
<div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
