Question

我正在使用foreach写下我的PDO结果中的所有元素（我在DB上提出了一个问题，它返回了一些data --> lot of data）。我把所有这些都写到了表格中（基本上它看起来像管理界面，如果你需要想象它，当你在CMS中管理并希望看到所有帖子或文章时，它就是这样）。

问题是当我想从该表中选择一行时（例如：我想选择文章New age of cellphones，这是在41行）并打开这篇文章（会有一些选项）如编辑，删除等）它选择FIRST元素（首先写成article -> lowest ID）。你能救我一下吗？

foreach($resultedArticle as $data){
    $short_content = substr($data["Content"], 0, 30);
    $short_description = substr($data["Description"], 0, 30);
    echo "                      
        <tr>
            <td>". $data['ID'] ."</td>
            <td>". $data['Name'] ."</td>
            <td>". strip_tags($short_description) ."...</td>
            <td>". strip_tags($short_content) ."...</td>
            <td>". $data['Type']. "</td>
            <td>". $data['Created'] ." </td>
            <td>". $data['Modified'] ."</td>
            <td>". $data['Status'] . "</td>
            <td> <a href='#modal1' class='modal-trigger' title='Zobrazit detaily zápisu'><i class='material-icons'>fullscreen</i></a></td>
            <td> <a href='#modal_edit' title='Editovat zápis'><i class='material-icons'>mode_edit</i></a></td>
            <td> <a href='../../core.php?action=deleteArticle&ID=". $data['ID'] ."' title='Smazat zápis'><i class='material-icons'>clear</i></a></td>
        </tr>
        <div id='modal_edit' class='modal modal-fixed-footer'>

编辑：您可以注意到我在同一个foreach中创建模态窗口（窗体）也没有问题吗？

请尝试使用此代码我已将ID添加到每个模态中基本上这不是使用模态的正确方法，而不是你可以在循环外只创建一个模型并用jQuery或javascript填充所有数据，现在它将起作用

foreach($resultedArticle as $data){

    $modal_id = "#modal_edit_$data['ID']";         

    $short_content = substr($data["Content"], 0, 30);
    $short_description = substr($data["Description"], 0, 30);
    echo "                      
        <tr>
            <td>". $data['ID'] ."</td>
            <td>". $data['Name'] ."</td>
            <td>". strip_tags($short_description) ."...</td>
            <td>". strip_tags($short_content) ."...</td>
            <td>". $data['Type']. "</td>
            <td>". $data['Created'] ." </td>
            <td>". $data['Modified'] ."</td>
            <td>". $data['Status'] . "</td>
            <td> <a href='#modal1' class='modal-trigger' title='Zobrazit detaily zápisu'><i class='material-icons'>fullscreen</i></a></td>
