php - 将当前 $row 值传递给 Bootstrap Modal

Question

桌子：

<table class="table table-bordered">
        <thead>
            <tr>
                <th>Works At</th>
                <th>First Name</th>
                <th>Middle Initial</th>
                <th>Last Name</th>
                <th>Start Date</th>
                <th>SSN#</th>
                <th>Modify</th>
            </tr>
        </thead>
        <?php
            $query = "SELECT * FROM employees";

            $stmt = $db->prepare($query);
            $stmt->execute();

            foreach ($stmt as $row): ?>
                <tr>
                    <td><?php echo $row['rest_id_employees']; ?></td>
                    <td><?php echo $row['fname']; ?></td>
                    <td><?php echo $row['minit']; ?></td>
                    <td><?php echo $row['lname']; ?></td>
                    <td><?php echo $row['start_date']; ?></td>
                    <td><?php echo $row['ssn']; ?></td>
                    <td style="text-align: center">
                        <div class="btn-toolbar">
                            <div class="btn-group">
                                <a class="btn btn-danger" href="<?php echo $_SERVER['PHP_SELF'].'?ssn='.urlencode($row['ssn']); ?>#delModal" data-toggle="modal"><i class="icon-trash icon-white"></i> Delete</a>
                                <a class="btn btn-warning" href="#editModal"><i class="icon-wrench icon-white"></i> Edit</a>
                            </div>
                        </div>
                    </td>
                </tr>
        <?php endforeach; ?>
    </table>

我的目标是将 $row['ssn'] 的值传递给我的#delModal。我认为问题在于：

<a class="btn btn-danger" href="<?php echo $_SERVER['PHP_SELF'].'?ssn='.urlencode($row['ssn']); ?>#delModal" data-toggle="modal"><i class="icon-trash icon-white"></i> Delete</a>

据我了解，使用上述语法，我应该能够$_GET['ssn']在 Bootstrap Modal 中使用来提取值，但是当我var_dump($ssn)只NULL打印值时。

这是模态：

<div class="modal hide" id="delModal" aria-hidden="true">
        <div class="modal-header">
            <h3 style="color: red">WARNING</h3>
        </div>
        <div class="modal-body">
            <?php
                $ssn = $_GET['ssn'];
                var_dump($ssn);
            ?>
            <h4>You are about to delete --- from your Employee database.</h4>
            <p>An employee cannot be recoverd once they have been deleted. They can be added to the system again, but
                all data about the employee will be lost if you delete them. Are you sure you mean to delete this
                employee from the database?</p>
        </div>
        <div class="modal-footer">
            <button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button>
            <a class="btn btn-danger" href="deleteemployee.php?ssn=<?php echo urlencode($ssn); ?>"><i class="icon-trash icon-white"></i> Delete</a>
        </div>
    </div>

此实现的总体目的是使用 Modal 作为一种通过提示用户警告来避免意外删除员工的方法。我不能只$row在 Modal 中使用，因为它每次都会拉出最后一行，而且我确信有比我在这里尝试做的更好的方法来实现我想要做的事情，但我不是确定那是什么。

您好，我遇到了与您使用的相同的问题和几乎相同的代码。但是我稍后可以通过将我的参数值作为 href id 传递来解决该问题。

我有一个名为 READ 的按钮，用于打开我的模型窗口。这是我的按钮的 HTML 代码。

<a button type="button" href="#<?php echo''.$u_id.'';?>" data-toggle="modal" class="btn btn-primary"> READ  </a>

在上面的代码中，您可以看到我使用了消息的 id（列名和主键）作为 href id！

这是我的模型窗口代码

<div class="modal" id="<?php echo''.$u_id.'';?>">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
          <h4 class="modal-title">Create public Event</h4>
      </div>
      <div class="modal-body">

    <?php echo '.$u_id.';?>
    </div>
  </div>
</div>

因此，一旦我将 id（参数）传递给模态，我就可以使用简单的 sql 查询获取其他值。

因此，对于您的代码，我建议您将主键列值（例如：id）作为按钮 href id 和 div id 传递。

最好的方法是使用 Jquery Ajax 调用，如下所示： - 1. 创建一个获取参数（或更多）的函数。2.用于处理Ajax post方法。3. 并在模态 div 中返回打印 HTML 数据。4.调用该函数以及模态按钮“onClick”事件......

我面临着一个类似的情况。我的解决方案是：

private function pri_show_weekcontent($p_sCourse){ 

for($iWeekcounter=1;$iWeekcounter<=10;$iWeekcounter++){ 
// Fetch the nesseray data from the database       
    $aCellContent = $this->fetchAssignmentscontents($p_sCourse,$iWeekcounter);
// Create an unique ID for the modal, in my case course+weeknumber
    echo("<div id='".$p_sCourse.$iWeekcounter."' class='modal fade' role='dialog'>");
// Build the modal
    echo("<div class='modal-dialog'>");
        echo("<div class='modal-content'>");
          echo("<div class='modal-header'>");
            echo("<button type='button' class='close' data-dismiss='modal'>&times;</button>");
            echo("<h4 class='modal-title'>Toelichting opdracht</h4>");
          echo("</div>");
          echo("<div class='modal-body'>");
// show the content from the database
            echo("<p>".$aCellContent[0][6]."</p>");
          echo("</div>");
          echo("<div class='modal-footer'>");
            echo("<button type='button' class='btn btn-default' data-dismiss='modal'>Close</button>");
          echo("</div>");
        echo("</div>");
      echo("</div>");
    echo("</div>");

    if(!empty($aCellContent)){
        if($_SESSION['verifiedUser']=='true'){echo("<td align='center' width='8%' bgcolor='white'><a href='editassignment.php?rn=".$aCellContent[0][0]."'><span title='".$aCellContent[0][6]."'>".$aCellContent[0][5]."</span></a></td>"); }
// call the unique ID model with a click.           
        else{echo("<td align='center' width='8%' bgcolor='white'><a data-toggle='modal' data-target='#".$p_sCourse.$iWeekcounter."'>".$aCellContent[0][5]."</a></td>");}
    }else{
        if($_SESSION['verifiedUser']=='true'){echo("<td align='center' width='8%' bgcolor='lightgreen'><a href='addassignment2.php?cn=".$_SESSION['sClassname']."&oo=".$p_sCourse."&pn=".$_SESSION['iPeriodNumber']."&wn=".$iWeekcounter."'>Geen huiswerk</a></td>");}
        else{echo("<td align='center' width='8%'>&nbsp;</td>");}
    }        
}

}

而不是传递值作为 get 直接在模型中回显您的值，并获得两者都在同一个文件中的优势。

像这样调用你的模型

<a class="btn btn-danger" href="#delModal" data-toggle="modal"><i class="icon-trash icon-white"></i> Delete</a>

在模型中尝试这样

<div class="modal hide" id="delModal" aria-hidden="true">
    <div class="modal-header">
        <h3 style="color: red">WARNING</h3>
    </div>
    <div class="modal-body">
            <?php echo $row['ssn']; ?>
        <h4>You are about to delete --- from your Employee database.</h4>
        <p>An employee cannot be recovered once they have been deleted. They can be added to the system again, but
            all data about the employee will be lost if you delete them. Are you sure you mean to delete this
            employee from the database?</p>
    </div>
    <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button>
        <a class="btn btn-danger" href="deleteemployee.php?ssn=<?php echo urlencode($ssn); ?>"><i class="icon-trash icon-white"></i> Delete</a>
    </div>
  </div>

希望这可以帮助。
