Php send multiple parameters to another page

Question

I have a create itinerary project. All the available destination is listed on my right panel and can be selected by button click. After the user select the desire destination/s it will be displayed on my right panel in the same page, in that part all is working great. I have also successfully pass the selected destination value into the url using session but when I am about to display it on another page what I'm getting is the only last value of selected destination. Can anyone know any solution or work around? Any help would be very much appreciated. Thank you in advance!

Below is the screenshot of my project and codes for your reference.

This is my right panel view where user can select a destination/s.

This is my codes for selecting a destination/s.

<?php
session_start();
if(!empty($_SESSION['destinationID'])){
        $destinationID = $_SESSION['destinationID'];
    }        
$dropdown_destination = $_GET['dropdown_destination']?:null;
$dropdown_tourdate = $_GET['dropdown_tourdate']?:null;
require_once("dbcontroller.php");
$db_handle = new DBController();
if(!empty($_GET["action"])) {
switch($_GET["action"]) {
  case "add":
    if(!empty($_POST["quantity"])) {
      $productByCode = $db_handle->runQuery("SELECT * FROM tourist_spot WHERE TOURIST_SPOT_ID='" . $_GET["code"] . "'");
      $itemArray = array($productByCode[0]["TOURIST_SPOT_ID"]=>array('TOURIST_SPOT'=>$productByCode[0]["TOURIST_SPOT"], 
        'code'=>$productByCode[0]["TOURIST_SPOT_ID"], 
        'quantity'=>$_POST["quantity"], 
        'PRICE_PER_LOC'=>$productByCode[0]["PRICE_PER_LOC"]));

      if(!empty($_SESSION["cart_item"])) {
        if(in_array($productByCode[0]["TOURIST_SPOT_ID"],array_keys($_SESSION["cart_item"]))) {
          foreach($_SESSION["cart_item"] as $k => $v) {
              if($productByCode[0]["TOURIST_SPOT_ID"] == $k) {
                if(empty($_SESSION["cart_item"][$k]["quantity"])) {
                  $_SESSION["cart_item"][$k]["quantity"] = 0;
                }
                $_SESSION["cart_item"][$k]["quantity"] += $_POST["quantity"];
              }
          }
        } else {
          $_SESSION["cart_item"] = array_merge($_SESSION["cart_item"],$itemArray);
        }
      } else {
        $_SESSION["cart_item"] = $itemArray;
      }
    }
  break;
  case "remove":
    if(!empty($_SESSION["cart_item"])) {
      foreach($_SESSION["cart_item"] as $k => $v) {
          if($_GET["TOURIST_SPOT_ID"] == $k)
            unset($_SESSION["cart_item"][$k]);        
          if(empty($_SESSION["cart_item"]))
            unset($_SESSION["cart_item"]);
      }
    }
  break;
  case "empty":
    unset($_SESSION["cart_item"]);
  break;  
}
}
?>

If user click add the selected destination will be displayed on the left panel.

This is my code on how I display the selected destination to left panel and passing the parameters to URL.

<div class="ui teal segment">
          <?php
          if(isset($_SESSION["cart_item"])){
          $total_quantity = 0;
          ?>
           <div class="">
            <?php   
              foreach ($_SESSION["cart_item"] as $item){
            ?>
            <div class="ui clearing segment iti-details">
             <div class="ui left floated header">
                <h2 class="ui header">
              <img class=" large image" src="resources/images/bg6.jpg">
              <div class="content">

                <div class=""><?php echo $item["TOURIST_SPOT"]; ?>
                </div>
              </div>
            </h2>
              </div>
              <div class="ui right floated header">
                <i class="ellipsis vertical icon iti-mini"></i>
              </div>
            </div>
            <div class="ui divider"></div>
            <?php
              $total_quantity += $item["quantity"];
              ?>
              <form action ="checkprice.php">
                  <input type = "text" name = "destinationID" value = "<?php echo $item["code"];?>">
                  <?php
            }
            ?>
           </div>
            <?php
            } else {
            ?>
            <div class="no-records">Your Tour Destination is Empty</div>
            <?php 
            }
            ?>       
          </div>

And this is my URL from another page. In this view the selected destination/s is displayed in URL but not in page.

PHP overwrites GET parameters of the same name, unless you use [] in the name to create an array - ?foo[]=value1&foo[]=value2&… — 04FS

U can use explode() to help u out.

$url_array =  explode('/', $_SERVER['REQUEST_URI']) ;
$url = end($url_array);

just assign it to a value then explode to an array of objects, the string u get u can use directly in a query.

As soon as that php page is requested by user u can grab the url as string. You could grab it on previous with params added to next.

Can you please elaborate? I mean, how I'm going to handle the page button clicked without page refresh? Thank you

You don't, php does. When user clicks say on www.example.com/home? and you have him select destinations etc. then when he goes to next page you could grab those items when opening new via session or use request uri from the server then explode into array. The uri grabs whatever is in top without www.example.com/home?etchere here is a link about globals php.net/manual/en/reserved.variables.globals.php

parse_str() function can be used to get URI parameters at once. More details can be found on this link. Also, above parameters can also directly assign to variables with following code.

<?php extract(parse_str($_GET)); ?>

with this you can directly check the get parameter and print its value.

For an example, if url will is http://www.example.com/test?param1=hi&param2=hello

you can directly print the value of param1 with following code.

<?php echo $param1; ?>
