Session cart advice.

Hello All,

 

Iam creating a shopping cart and basing the session content iam adding a add / remove to the product.

 

First question is that a good away of doing it? 

 

Second would be Iam throwing a error if the $_session doesn't exist for both the session and the 'array_key_exists' Would best way to solve this be by wrapping it iin a if if($_SESSION["cart_products"]) {the code below} else {out put add button}

  $out = "
  <div class='row'>
    <form method='post' action='http://localhost/cart/'>
    <div class='medium-4 columns'>
      {$room->title}  {$room->id}
    </div>
    <div class='medium-4 columns'>
      £{$room_cost_pp} p/p x {$room->room_spaces} guests = £{$room_cost}
    </div>
    <div class='medium-2 columns'>
  <input type='hidden' name='cabin_id' value='{$room->id}' />
  <input type='hidden' name='cabin_name' value='{$room->title}'/>
  <input type='hidden' name='cabin_cost' value='{$room_cost}'/>
  <input type='hidden' name='return_url' value='{$current_url}' />";

 $search_array = $_SESSION["cart_products"];
if (array_key_exists($room->id, $search_array)) {
        $out.="<input type='hidden' name='remove_code[]'' value='{$room->id}' />
        <button type='submit' class='alert button'>Remove Cabin</button>";
  }else {
        $out.="<input type='hidden' name='type' value='add' />
        <button type='submit' class='success button'>Add Cabin</button>";
      }

Cheers

use isset() to (directly) test if the item is in the cart or not -

if(isset($_SESSION["cart_products"][$room->id])) {

Iam using the follow but cant seem to get it to work. If i remove the isset() it works but throws a error once the session has be destroyed.

<?php if(isset($_SESSION["cruise_id"]) == $page->id) {

}else{
  $_SESSION = "";
  session_destroy() ;
}?>

Scrap that Ive just looked into isset() and realised that its would only return true/false. So I went with the following that ok to use?

<?php 
if(isset($_SESSION["cruise_id"])) {
  if($_SESSION["cruise_id"] != $page->id) {
  $_SESSION = "";
  session_destroy() ;
}
} ?>
