Question

我有一个由question_id，问题和选项组成的数据库。我将在其中显示问题和选项。当用户单击提交时，我要存储他们单击的选项和question_id。我能够存储他们单击的选项，但想知道如何存储question_id。

$user_email = $_SESSION['email'];
$query1="SELECT * FROM votes WHERE user_email='$user_email'";
$query2="SELECT * FROM poll_question WHERE status='1'";
$fetch2 = mysqli_query($con,$query2);

            while( $row2 = mysqli_fetch_array($fetch2))
            {
             ?>
              <form method="post" class="poll_form">
                <h3><?echo $row2['question']?>?</h3>

                     });
                $.post("poll_vote.php",$('.poll_form').serialize(),

                           window.setTimeout(function () {
                                location.href ="<?php echo SITE_URL; ?>poll.php";
                            }, 100);
                      }
                      else{

                          $("#result").html(data);
                      }
                     }
                  );
             //to reset form data
        }); 
    });
    <? } ?>
    </script>

</html>

使用下面的函数，我将poll_option发送给其他保留插入操作的位置。现在，我也要发送question_id

Answer 1

在表单中创建隐藏的输入文件

<input type="hidden" name="question_id" value="<?php echo $row2['question_id']; ?>">

Answer 2

Create a hidden input field in your form.

<input type="hidden" id="question_id" name="question_id" value="<?= $row2['question_id'] ?>">

PHP solution:
In this case your question_id will be included in the POST.
You can then access it by calling $_POST['question_id'].

Jquery solution:
In Jquery you can also access it by:

$("#question_id").val();

单击提交时如何将ID从一页发送到另一页？
