如何使用复选框（PHP）从动态表中选择一行并插入这些行以发送邮件功能

嗨，我有一个页面，显示我表格的所有内容。除了表中的每一行，我还有一列包含复选框。当用户通过勾选复选框并按下submit按钮选择一行或多行时，我只希望这些行出现在下一页（material.php）的表格中。我知道它基本上是一个select语句。但我不知道如何处理这个问题。有人能帮忙吗？谢谢

<td><input type='checkbox' name='material[]' value='material[<?php echo $id;?>]' /></td>

尝试以下内容：
为了安全起见，使用准备好的声明：

<table>
        <?php
        foreach ($_POST['material'] as $item) {  // loop your post array
            $query = "SELECT col1,col2,col3,col4 FROM model_material WHERE id = 
             ?";   // prepare a query
            $stmt = $db_con->prepare($query);
            if ($stmt) {
               $stmt->bind_param("i",$item);  // bind the integer id ($item)
               $stmt->execute();    // fire it
               $stmt->bind_result($col1,$col2,$col3,$col4);  // bind the selected rows to each variable
               $stmt->store_result();   //incase of large results prevents memory error
                while ($stmt->fetch()) {   // loop your results like $result fetch assoc
                   echo "<td>".$col1."</td>";   // display data
                   echo "<td>".$col2."</td>";
                   echo "<td>".$col3."</td>";
                }
               $stmt->close();   // close statement
            }
          }
           $db_con->close();  // close database
        ?>
    </table>
