通过 POST PHP 再发送一个值

Question

这是我的第一篇文章，欢迎！

我正在为我的项目中的一个问题而苦苦挣扎。正如您在我的屏幕截图中看到的那样，我从数据库中获取的名称很少，并显示在主菜单中。单击“模态”按钮后，引导程序中的模态以 php 形式显示。用户可以输入一个 4 位数的密码，下一步是将此密码与数据库记录匹配。但是 2 个用户可以拥有相同的 pin，所以我不仅需要将 pin 与数据库进行比较，还需要比较名称。我不知道如何通过帖子发送“名称”值。这是我的代码和屏幕截图：

index.php:

  <?php 
 $data = $worker->select_workers();
$worker->show_workers($data);
$worker->show_modal();

worker.php：

<?php 
require_once('db.php');
class Worker extends db {

protected $select_workers;
    public function select_workers(){

                return $this->select_workers = $this->query('SELECT * FROM worker')->fetchAll();
    }

    public function show_workers($data){
        foreach ($data as $users) {
    echo '<p id="p_name">'.$users['name'].'</p><a id="button_modal" href="/?name='.$users['name'].'" type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
  Modal
</a><br>';

}
}
    public function show_modal(){
echo '<!-- Button trigger modal -->


<!-- Modal -->
<form action="test.php" id="submit_ajax" method="post">
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="modal_title" name="name"></h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <input id="hidden_name" type="text" value="" name="name" />
Hasło:<input type="text" name="password"><br>



      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button  type="submit" class="btn btn-primary">Przerwa/powrót</button>
        </form>
      </div>
    </div>
  </div>
</div>';
    }

我相信这个解决方案真的很简单，但像往常一样 - 我浪费了太多时间来处理那些不起作用的复杂事情。对不起我的英语，这不是我的母语:) 谢谢

Answer 1

把值放在这里<input id="hidden_name" type="text" value="<?= $name ?>" name="name" />，但是如果你从db中获取数据，使用ids而不是names不是更好吗？

Answer 2

不干净的解决方案。让每个工人都成为模态。

<?php 
require_once('db.php');
class Worker extends db {

protected $select_workers;
    public function select_workers(){

                return $this->select_workers = $this->query('SELECT * FROM worker')->fetchAll();
    }

    public function show_workers($data){
        $i=0;
        foreach ($data as $users) {
        $i++;
    echo '<p id="p_name">'.$users['name'].'</p><a id="button_modal" href="/?name='.$users['name'].'" type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal'.$i.'">
  Modal
</a><br>
<!-- Button trigger modal -->


<!-- Modal -->
<form action="test.php" id="submit_ajax" method="post">
<div class="modal fade" id="exampleModal'.$i.'" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="modal_title" name="name"></h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <input id="hidden_name" type="text" value="'.$users['name'].'" name="name" />
Hasło:<input type="text" name="password"><br>



      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button  type="submit" class="btn btn-primary">Przerwa/powrót</button>
        </form>
      </div>
    </div>
  </div>
</div>';
    }
