问题描述
我有一个名为new.php的php文件。在其中，我将一些数据存储在三个变量中。
I have a php file named new.php.In it,I've stored some data in three variables.
$sdate = "";
$stime = "";
$seats = "";
点击按钮时
When clicked on a button as
<pre lang="HTML"><pre><button onclick="location.href = 'http://localhost/My%20Project/booking.html';" id="myButton" class="float-left submit-button" >Proceed</button>在这个php页面上，我被重定向到一个名为booking.php的新php页面。（实际上，一个html表单已经嵌入到这个php文件中。这是重定向的原因。）
我想要做的就是，当点击上面的按钮时，三个变量也应传递给booking.php文件。
是否可以这样做？
如果是这样，我该怎么办？
我尝试过：
on this php page,I'm redirected to a new php page named booking.php.(Actually,an html form has been embeded to this php file.It's the reason for redirection.)
All I want to do is,when clicked the above button,the three variables should be passed to the booking.php file too.
Is it possible to do so?
If so,how can I do it?
