Question

我有一个分段标记，根据用户点击page1.php中的包的内容来更新其值。即没有选择，部分标签中没有任何内容，用户现在选择包1作为包标签，因为包1.但是当我使用php POST它并检查它是否设置它是不是有一个原因是什么？

我希望设置POST_['foodchoice']，以便我可以在page2.php中有一个部分，我可以在其中总结用户选择的包。

有点像购物车功能，但没有数据库，数量选择等。请告知原因。感谢

page1.php中

<script type ="text/javascript">


function changemyButton() 
{
  var elem = document.getElementById("button3");
  if (elem.value == "Un-Select Package") 
    elem.value = "Select This Package";
  else if( elem.value == "Package Selected!" ) {
      elem.value = "Select This Package";
       elem.style.background = "#003e7e";
       document.getElementById("selection").innerHTML = '';

  } else {
    elem.value = "Package Selected!";
    elem.style.background = "green";
    document.getElementById("selection").innerHTML = '1x The Share Collection';
  }



}
</script>

<h1 id="logo">      Breakfast Menu Options          </h1></section> 

<hr>

</br>
 <center>


<form action="homePage.php" method="post" onsubmit="">
<center>

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js">             </script>
 <div class= "breakfast">
<u><h2>The Share Collection</h2></u>
</br>
<img src= "\images\Breakfast\breakfast1.jpg" class="funky">
 </br>
 </br>
 <dl>
 <dd>Mini jar of housemade granola: vanilla yoghurt, fresh fruit (v) (6)</dd>
 <dd>Goat cheese, cherry tomato &amp; basil, mushroom tart (v) (8)</dd>


<dd>Mini slider jamon serrano, fig jam, rocket, brie &amp; black pepper (8) </dd>
 <dd>Chef's mini sweet muffin (v) (8)</dd>
 <dd>Bowl of strawberries &amp; grapes (v) (1)</dd>
 </dl>
 </br>
 <input type='button' value='Select This Package' id='button3' onclick="changemyButton()">
<hr>
   <section id="myform">    
    <h1 id="logo">Total Ordered</h1></section>
<hr>
</br>
<section id ="selection" name="foodchoice"></section>



<br>
<br>
<br>
<br>



<input type="button" id="button4" value="Submit Your Selection" name="submit" onclick="window.location='homePage.php';" >
</div>



    </center>
    </form>


    </div>
    </div>

第2.pp页

<?php 

session_start();
error_reporting( E_ALL & ~E_NOTICE );


if (!isset($_SESSION['time'])) {

header("Location: openingPage.php");

exit();

}

if (isset($_POST['foodchoice'])) 
{
   echo "yay!";
}

  if (!isset($_POST['foodchoice']))

  {

echo "nay!";

  }


?>

然后在我的html体内，我会：

<div id ="packageselected">

<?php  echo $_POST['foodchoice'];   ?>

</div>

为什么我的部分标签不会发布到我的其他页面？
