Hello i am creating a simple web app, that users can log in and purchase food stuffs. i have used a tutorial i got online link to tutorial
to implement the ordering aspect of this web app,
now i have implemented a user syatem so that users have to sign in to make an order.
my problem is i noticed that the same cart information is shown to multiple users when logged in, which is wrong. every user should have their own different cart information based on what they might have added up.
so i am asking how can i tie cart information to logged in users or each users.
this is my code snippet
product.php
<head>
<script>
function showEditBox(editobj,id) {
$('#frmAdd').hide();
$(editobj).prop('disabled','true');

$("#message_" + id + " .message-content").html(editMarkUp);
}
function cancelEdit(message,id) {
$("#message_" + id + " .message-content").html(message);
$('#frmAdd').show();
}
function cartAction(action,product_code) {
var queryString = "";
if(action != "") {
switch(action) {
case "add":
queryString = 'action='+action+'&code='+ product_code+'&quantity='+$("#qty_"+product_code).val();
break;
case "remove":
queryString = 'action='+action+'&code='+ product_code;

i have tried to change the $_SESSION["cart_item"] to something that would always change $_SESSION["MM_Username"], my thinking was that it would probably create the cart variable name based on who was logged in, but that approach didnt seem to go well,
can some one please help here
I'm learning how can i use ajax, jquery and php to update a cart. I found this code and i'm trying to adapt it, but without success. The problem is that i can't add any item to the cart and after a search on google still don't understand where is the problem.
<script>
$(document).ready(function(){
$(".form-item").submit(function(e){
var form_data = $(this).serialize();
var button_content = $(this).find('button[type=submit]');
button_content.html('Adding...'); //Loading button text
$.ajax({ //make ajax request to cart_process.php
url: "../../cart_process.php",
type: "POST",
dataType:"json", //expect json value from server
data: form_data
}).done(function(data){ //on Ajax success
$("#cart-info").html(data.items); //total items in cart-info element
button_content.html('Add to Cart'); //reset button text to original text
alert("Item added to Cart!"); //alert user
if($(".shopping-cart-box").css("display") == "block"){ //if cart box is still visible
$(".cart-box").trigger( "click" ); //trigger click to update the cart box.
}
})
e.preventDefault();
});
//Show Items in Cart
$( ".cart-box").click(function(e) { //when user clicks on cart box
e.preventDefault();
$(".shopping-cart-box").fadeIn(); //display cart box
$("#shopping-cart-results").html('<img src="images/ajax-loader.gif">'); //show loading image
$("#shopping-cart-results" ).load( "../../cart_process.php", {"load_cart":"1"}); //Make ajax request using jQuery Load() & update results
});
//Close Cart
$( ".close-shopping-cart-box").click(function(e){ //user click on cart box close link
e.preventDefault();
$(".shopping-cart-box").fadeOut(); //close cart-box
});
//Remove items from cart
$("#shopping-cart-results").on('click', 'a.remove-item', function(e) {
e.preventDefault();
var pcode = $(this).attr("data-code"); //get product code
$(this).parent().fadeOut(); //remove item element from box
$.getJSON( "../../cart_process.php", {"remove_code":pcode} , function(data){ //get Item count from Server
$("#cart-info").html(data.items); //update Item count in cart- info

Moving forward from our discussion in the comments, I will be posting a functional behavior of the code with a sample data from database since you wanted it to be dynamic.
As this was for learning purpose I've had used prepared statements with some msql_. (both in different files) Please note that msql_
is deprecated and I urge not to use it.
Before starting, I assume you have all the required files downloaded and saved in the correct path and used either method (filesystem/storing directly to database) for the images, I have however used the filesystem behavior. Now, there are three tables used from the database:
1) category table with columns as follow:
cat_id
cat_name
2) item table which has the columns as follow:
item_id
item_name
item_quantity
item_size
cat_id (FK from category table)
item_color
3) products_list table with following columns:
id (AI, PK)
product_name
product_desc
product_code
product_image
item_id (FK from item table)
product_price
product_discount
Now, Starting with the very first page.

Now comes the part when you click on "Check-out" in your add-to-cart box. It takes you to another page (the last one in our case) where you can see all the products that you have bought.

I have run and checked all the processing before posting this here, So it should help you understand the exact behavior and the way to move along.

I am stuck on integrating paypal payment gateway on codeigniter
I am using the current library
https://github.com/romaldyminaya/ci_paypal
As the library contains only static values of the items , but i need to get the items that are coming from my cart, how can i get them to the $this->paypal->add('T-shirt',2.99,6);
my controller function:
public function do_purchase(){
$config['business'] = 'babar.seller#gmail.com';
$config['cpp_header_image'] = ''; //Image header url [750 pixels wide by 90 pixels high]
$config['return'] = 'http://localhost/final-project/index.php/mysite/modify_payment';
$config['cancel_return'] = 'http://final-project/mysite/canceled.php';
$config['notify_url'] = 'process_payment.php'; //IPN Post
$config['production'] = FALSE; //Its false by default and will use sandbox
$config["invoice"] = random_string('numeric',8); //The invoice id
$this->load->library('paypal',$config);
#$this->paypal->add(<name>,<price>,<quantity>[Default 1],<code>[Optional]);
$this->paypal->add('T-shirt',2.99,6); //First item
$this->paypal->add('Pants',40); //Second item
$this->paypal->add('Blowse',10,10,'B-199-26'); //Third item with code
$this->paypal->pay(); //Proccess the payment
}
public function modify_payment(){
$received_data = print_r($this->input->post(),TRUE);
echo "<pre>".$received_data."<pre>";
$this->load->view('mysite/modify_payment',$received_data);
}
public function cart()
{
$cart = $this->cart->contents();
//print_r($cart);
//die;
//$data['user_id']=$this->mainmodel->get_user_i($user_id);
$this->load->view('mysite/cart');
$this->load->view('mysite/include/footer');
}
cart view :
<?php $i = 1; ?>
<?php foreach ($this->cart->contents() as $items): ?>
<?php echo form_hidden($i.'[rowid]', $items['rowid']); ?>
<tr>
<td> <input name="qty[<?php echo $items['rowid'];?>]" id="qty" type="text" value="<?php echo $items['qty']?>" class="input" />
</td>
<td>
<?php echo $items['name']; ?>
<?php if ($this->cart->has_options($items['rowid']) == TRUE): ?>
<p>
<?php foreach ($this->cart->product_options($items['rowid']) as $option_name => $option_value): ?>
<strong><?php echo $option_name; ?>:</strong> <?php echo $option_value; ?><br />
<?php endforeach; ?>
</p>
<?php endif; ?>
function add($item_name = '',$item_amount = NULL,$item_qty = NULL,$item_number = NULL){
$this->config['item_name_'.$this->item] = $item_name;
$this->config['amount_'.$this->item] = $item_amount;
$this->config['quantity_'.$this->item] = $item_qty;
$this->config['item_number_'.$this->item] = $item_number;
$this->item++;
}
What i did is had a paypal library class that handled the addition and just simply hard coded inn some products

Hi the page is not showing any errors. but the first product fetched from the database is not added to the cart.except the first one all are adding
I am trying to make a simple MSSQL and PHP shopping cart for my website. The page index.php correctly retrieves the products from my MSSQL products table and displays them. For each product displayed there is an Add to Cart button. The button should use $_SESSION to store the added product into the shopping cart via the cart_update.php page. The products added to the shopping cart should be displayed at the bottom of the index.php page. Currently, when the Add to Cart button is hit, no products are added to the shopping cart. I am unsure why this is happening.
Here is my index.php page code:
<?php
session_start();
include_once("config.php");
?>

<head>
<meta charset="utf-8">

$current_url = base64_encode("http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
$query = "SELECT * FROM products ORDER BY id ASC";
$results = mssql_query($query, $mysqli);
if ($results) {
//output results from database
while($obj = mssql_fetch_object($results))
{
echo '<div class="product">';
echo '<form method="post" action="cart_update.php">';
echo '<div class="product-thumb"><img src="images/'.$obj->product_img_name.'"></div>';

Thank you for any help. All help is greatly appreciated.
To add products to the shopping cart I had to change the query in the cart_update.php page where
$query = "SELECT product_name,price FROM products WHERE product_code='$product_code LIMIT 1'";
to
$query = "SELECT TOP 1 product_name,price FROM products WHERE product_code='$product_code'";
This is because LIMIT does not work in SQL Server, and the equivalent is TOP.
