php - php如何将数据从一个类替换到另一个类

Question

嗨，我有一个结帐页面，用户可以在他们的帐户中存储多个地址。在结帐页面上，它将显示主要地址。我希望能够允许用户从地址列表中进行选择，并更改主要地址所在位置的信息。我怎样才能做到这一点？

//SHOW PRIMARY ADDRESS FROM DB set by user

// $myid is users id from DB

<?php

$primaryaddsql = "SELECT * FROM cust_address WHERE cust_ID = '$myid' AND primary_add = '1'";
$primaryadd = mysqli_query($conn,$primaryaddsql); 
$mainaddress = mysqli_fetch_assoc($primaryadd)

echo'
<div class="mainAdd" >
<p class="thisadd">'.$mainaddress['address_1'].'</p>
<p class="thisadd">'.$mainaddress['address_2'].'</p>
<p class="thisadd">'.$mainaddress['city'].'</p>
<p class="thisadd">'.$mainaddress['country'].'</p>
<p class="thisadd">'.$mainaddress['post_code'].'</p>';  
 ?>


//SHOW ALL ADDRESSES FROM DB FOR USER TO CHOOSE FROM

 <?php
 $myaddsql = "SELECT * FROM cust_address WHERE cust_ID = '$myid' AND primary_add != '1' ";
 $myaddresults = mysqli_query($conn,$myaddsql);
while($myrow = mysqli_fetch_assoc($myaddresults)){
echo '

                            <div class="myleft" data-id="'.$myrow['address_ID'].'">
                             <p class="thisadd" >'.$myrow['address_1'].'</p>
                             <p class="thisadd">'.$myrow['address_2'].'</p>
                             <p class="thisadd">'.$myrow['city'].'</p>
                             <p class="thisadd">'.$myrow['country'].'</p>
                             <p class="thisadd">'.$myrow['post_code'].'</p>
                         </div>

                         ';
                }              
            ?>
