PHP - Multiple Add-to-cart Buttons

Hello,

I got my hands in a php tutorial about creating a custom cart using only php. The thing is that, the code is working like that:
1. you see the items in the items.php page
2. you click on an item to open it in a new page and see full description
3. the add button is in the specific item's page and that's how the code works. Grabs the URL' s id variable and then get's processed.

What I want:
1. To modify the code a little bit in order to have the add button into the into my items.php page so I skip the view full description link (I just don't like it as a requirement to add something to cart)

But somewhere on my way there I got lost... Here are the codes (as they work in original script):
For adding an item:
Code: [Select]
if (isset($_POST['pid'])) {
    $pid = $_POST['pid'];
   $wasFound = false;
   $i = 0;
   // If the cart session variable is not set or cart array is empty
   if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) {
       // RUN IF THE CART IS EMPTY OR NOT SET
      $_SESSION["cart_array"] = array(0 => array("item_id" => $pid, "quantity" => 1));
    } else {
      // RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
      foreach ($_SESSION["cart_array"] as $each_item) {
            $i++;
            while (list($key, $value) = each($each_item)) {
              if ($key == "item_id" && $value == $pid) {
                 // That item is in cart already so let's adjust its quantity using array_splice()
                  array_splice($_SESSION["cart_array"], $i-1, 1, array(array("item_id" => $pid, "quantity" => $each_item['quantity'] + 1)));
                  $wasFound = true;
              } // close if condition
            } // close while loop
          } // close foreach loop
         if ($wasFound == false) {
            array_push($_SESSION["cart_array"], array("item_id" => $pid, "quantity" => 1));
          }
   }
   header("location: ../p_cart.php");
    exit();
}The check URL variable & the Add Button (both at the same page) the link of "View All Details" looks like this in order for this to work: <a href="specitem.php?id=1"> so it grubs the URL' s id and executes the code (something that I don't want) I want to take the id from my item form.
Code: [Select]
<?php 
// Check to see the URL variable is set and that it exists in the database
if (isset($_GET['id'])) {
// Connect to the MySQL database  
    include "storescripts/connect_to_mysql.php"; 
$id = preg_replace('#[^0-9]#i', '', $_GET['id']); 
// Use this var to check to see if this ID exists, if yes then get the product 
// details, if no then exit this script and give message why
$sql = mysql_query("SELECT * FROM products WHERE id='$id' LIMIT 1");
$productCount = mysql_num_rows($sql); // count the output amount
    if ($productCount > 0) {
// get all the product details
while($row = mysql_fetch_array($sql)){ 
 $product_name = $row["product_name"];
 $price = $row["price"];
 $details = $row["details"];
 $category = $row["category"];
 $subcategory = $row["subcategory"];
 $date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
         }
 
} else {
echo "That item does not exist.";
    exit();
}

} else {
echo "Data to render this page is missing.";
exit();
} Code: [Select]
<form id="form1" name="form1" method="post" action="cart.php">
        <input type="hidden" name="pid" id="pid" value="<?php echo $id; ?>" />
        <input type="submit" name="button" id="button" value="Add to Shopping Cart" />
       </form>

Hello everyone

I have coded a php cart for my website. I coded one myself instead of using a big box because it is a membership based sites where users use credits to order not cash.

I have a 'Sizes' table with (size_id and size_name) and a 'Sizes_List' table with (size_id and product_id) which stores the size options of each product. It is displayed fine on the product page.

Anyhoo. It works great.. there aren't any actual errors in the code but I am having trouble with 3 things..

1. displaying the product size [i grab it in $_POST and add it to the cart_array) but it doesn't show up.
2. If I add another product, but a different size, to the cart it just changes the quantity of the product but doesn't add a new line.
3. I need to put items on "hold" for a certain amount of time (e.g. if you add a pair of True Religions in size 32 to your cart they are no longer available to anybody for 20 minutes and if you don't checkout they are back in the store).

For the purpose of this question I have removed the need to be logged in for 1 product page and the cart.

http://www.theskinnyminnie.com/user/rent/product.php?id=4/ <<product
http://www.theskinnyminnie.com/user/mybox.php <<cart

Here is the code it POST the values to the cart (if user adds to cart)

Code: [Select]
<div id="addproduct"><form id="form1" name="form1" method="post" action="../mybox.php">
            <div id ="size">Size:
      <select name="size">
      <?php echo $the_sizes;?>
    </select></div>
                <input type="hidden" name="pid" id="pid" value="<?php echo $id; ?>" />
                <input type="submit" name="button" id="button" value="Add to Box" />
              </form></div>
Here is the code for the cart

ok im making a shooping cart how do i make it so it remembers that items people add to the cart

Hello.

I want to implement a simple shopping cart with sessions but without using DB,
despite the fact that I have a DB consisting of Car-Shop-Customer.

Is the only way using arrays?

Hello all, so I'm in sort of a pickle here. I've been using a php tutorial on Youtube and I got to a point where i have to add products to cart using a users IP address. So far I've got no error pop up or anything. The scripts I've typed out in my functions.php are working well no error. But when I get to adding products using the website, the page only blinks , no items are added to the cart database and even the script alert which I'd set to echo doesn't display. Can  you find a way to help me out of this?  Below is my code...

 

 function getRealIpUser(){
    
    switch(true){
            
            case(!empty($_SERVER['HTTP_X_REAL_IP'])) : return $_SERVER['HTTP_X_REAL_IP'];
            case(!empty($_SERVER['HTTP_CLIENT_IP'])) : return $_SERVER['HTTP_CLIENT_IP'];
            case(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) : return $_SERVER['HTTP_X_FORWARDED_FOR'];
            
            default : return $_SERVER['REMOTE_ADDR'];
            
    }
    
}


  function add_cart(){

    global $db;

    if (isset($_GET['add_cart'])) {
      
      $ip_add =getRealIpUser();

      $p_id = $_GET['add_cart'];

      $product_qty = $_POST['product_qty'];

      $product_size = $_POST['product_size'];

      $check_product = "SELECT * FROM cart WHERE ip_add='$ip_add' AND p_id='$p_id'";

      $run_check = mysqli_query($db,$check_product);

      if (mysqli_num_rows($run_check)>0) {

       echo "<script>alert('This product has already added in cart')</script>";
       echo "<script>window.open('details.php?pro_id=$p_id','_self')</script>";
         
       } else {
        $query = "INSERT INTO cart (p_id,ip_add,qty,size) VALUES ('$p_id','$ip_add','$product_qty','$product_size')";

        $run_query = mysqli_query($db,$query);

         echo "<script>window.open('details.php?pro_id=$p_id','_self')</script>";
       }
    }
  }

I am using php 7 , Apache,  MySQL.... Any help will be much appreciated.
 

 

Hi everyone,

I am building a shopping cart for a group of friends' website. It is a pay-per-view workout website. Basically, they want to let people find workout videos and pay on a per-day basis (1 day, 3 days, 7 days and depending on the video pricing will be different). I have set them up everything except I am having some difficulty with the shopping cart. I took the basics of the shopping cart script from a tutorial I found online and then modified it. The only problem is that most shopping carts send an action and a product id through the URL and into the session for the shopping cart. Well, I need to also send a price id variable so that the cart will know which price to use. This is because they want to offer pricing on a per-day basis. How would I modify the cart.php page to accomplish this? I have tried, but cannot get the entire thing to work. All help is appreciated. Below is my code:
Code: [Select]
<?php
// if no session is set, initiate one
if (!isset($_SESSION))
{
session_start();
}

// see if the customer is logged in
//if (!isset($_SESSION['customer_id']))
//{
//header("location:login.php");
//}

// connect to the database
require_once('connect.php');

// select the database
mysql_select_db($database, $connect);

// get the video information
if (isset($_GET['video_id'])) {
$video_id = $_GET['video_id'];
} else {
$video_id = 1;
}
// get the action
if (isset($_GET['action'])) {
$action = $_GET['action'];
} else {
$action = "empty";
}
// get the video pricing information
if (isset($_GET['price_id'])) {
$price_id = $_GET['price_id'];
} else {
$price_id = "";
}

// do the following code based on the action
switch($action) {
// if the action is add then add the product id to the cart session array
case "add":
if (isset($_SESSION['cart'][$video_id])) {
$_SESSION['cart'][$video_id]++;
} else {
$_SESSION['cart'][$video_id] = 1;
}
break;
// if the action is remove then remove the product id from the cart session array
case "remove":
if (isset($_SESSION['cart'][$video_id])) {
$_SESSION['cart'][$video_id]--;
if ($_SESSION['cart'][$video_id]==0) {
unset($_SESSION['cart']);
}
}
break;
// if the action is empty then remove the cart session array completely
case "empty":
unset($_SESSION['cart']);
break;
}
?>

I have elaborated two plans but I don't know is those a good ideas in terms of bringing more store in to the website and have them comfortable by the way the website hold business with their stores owners.

1- I was thinking of collecting all the money of transactions into a single paypal account and then try to pay them weekly or in a monthly basis.
(I am not sure about this first option because I don't know whether the store owners will be thinking to much into it at the time of making a decision to register and to sell their products in the website. I guess they might think whether the website administrator will delivery the money every week, or if the website administrators are going to steal them etc. So this option I don't know if with some changes can be implemented.

2- The second option was to let each store administer each transaction with their credit/debit machine they have at the store and make the transaction right there and then on a monthly or weekly basis the website administrator charge them for the amount of transaction done during that time period in the website.


3- Third option is create a paypal account for each store and at the moment of the transaction to transfer the money to each store account and have the website paypal account deduct its percentage from the transaction and have the store owner paypal account deduct its part.

For healthy business purpose and website grow in terms of acquiring more stores into the website which of those three options would be the best option to choose or if there is another idea even better for business grow and comfortability among stores owner that you guys might have in mind share it.

Is selecting an option relevant to the grow of the website or it is?

HI,    Im trying to adapt a shopping cart script for an alternative use, on my local host XXMP scrip code works fine, but when i upload to my host I have problems,   Im making a Role-play page to assist with npc encounters, where you can add npc's to the encounter (Shopping Cart) see http://rptoolkit.com/encounter/ which is active and working   The issue is when I go to remove 1 of the 4 people from the encounter (Cart) it will remove all and duplicate the first entry on 2 lines, where this doesn't happen on my localhost.   Hope you can help shed some light as I'm confused why it will work on 1 but not the other maybe has to do with my PHP Versions.   Thanks. ----------------------------------------------------   Script code is below for the remove link button on the index page  

echo '<td><span> <a href="include/encounter_update.php?removep='.$cart_itm["code"].'&return_url='.$current_url.'"><img src="images/icon_delete.gif" alt="Delete"></a> </span></td>';

Hi,
I'm hoping someone can lead me in the right direction here. I'm creating a simple shopping cart that I will later pass on to Paypal for payment but my problem is, it won't add the items to my shopping cart when I click add to cart.

My products are on different pages and I'm not sure if that is going to matter.

When I click "add to cart" nothing gets added and it says my cart is empty. I have two tables with the following columns:

1. products:
        productId
        productName
        productDesc
        productPrice
        link (for dynamically creating the page links on the main product page)

2. productscents
       scentId
       scentName
       scentDesc


Here is the add code that is in my first products page (Elite Hand Cream):

Code: [Select]
<?php 


if(isset($_GET['action']) && $_GET['action'] == "add") {
$id = intval($_GET['id']);
$desc=intval($_GET['desc']);

if (isset($_SESSION['cart'][$id])) {
$_SESSION['cart'][$id]['quantity']++; 
}
else {
$sql3 = "SELECT * FROM products WHERE productId=[$id]";
$sql4= "SELECT * FROM productscents WHERE scentId=[$desc]";
$query3 = mysql_query($sql3);
$query4 = mysql_query($sql4);
if(mysql_num_rows($query3) != 0) {
$row3 = mysql_fetch_array($query3);
$row4 = mysql_fetch_array($query4);
$_SESSION['cart'][$row3['productId']] = array("quantity" => 1, "price" => $row3['productPrice'], "desc" => $row4['scentId']);
} 
}
}


?>

Here is code I have for the $_SESSION:
Code: [Select]
<?php 
if(isset($_SESSION['cart'])) {
$sql5= "SELECT * FROM products,productscents WHERE productId IN (";
foreach($_SESSION['cart'] as $id => $value) {
$sql5 .= $id . ",";
}
$sql5 = substr($sql,0,-1) . ") ORDER BY productId, scentId ASC";
$query = mysql_query($sql5);
if(!empty($query)) {
while($row = mysql_fetch_assoc($query)) {
?>
<?php echo $row['productName'];?><?php $_SESSION['cart'][$row['productId']]['quantity'];?>
<?php 
}  } else {
echo "You need to add an item to your cart";}
}



Here is the code that I have for the "add to cart" and "view cart":

Code: [Select]
<a href=#&action=add&id=<?php echo $prodId;?>&desc=<?php echo $scent_id[$y];?>>Add to Cart</a><br><a href="cart.php">View Cart</a>



This grabs the correct product Id and scent Id which I want and no errors are being displayed on the page.

I'm not sure where to begin with this. LOL. I'm new to PHP and I used a tutorial to help with the code.

Any help would be greatly appreciated.

I have a form which gets filled in with values from a session array. This form also has just one update button. If I have 3 items in my cart and I want to update just one of the items how would I pass the id of that product to my cart class? The problem I'm having is the id of the last product in the cart is passed so the update never works unless its the last item thats being updated. If I was to wrap each item in a form with an add update button it will work the way I want it to work but I really dont want to add extra buttons. Is there anyway to to wrap all the items in one form and get just the input values of the item whos quantity is being changed.
Here is the cart form:
Code: [Select]
<form action="index.php?view=update_cart" method="post" >
    <table id="items">
        <thead>
            <tr>
                <th>Item</th>
                <th>Item Price</th>
                <th>Qty</th>
                <th>Subtotal</th>
<!--                <th>Edit</th>-->
            </tr>
        </thead>
        <tbody>
            <?php foreach($cart->Cart() as $item):?>
                 <!--<form action="index.php?view=update_cart" method="post" >-->
                <input type="hidden" id="prodId" name="prodId" value="<?php echo $item['Id']; ?>" />
            <tr>
                <td><?php echo $item['Product']; ?></td>
                <td><?php echo '$'.$item['Price']; ?></td>
                <td><input type="text" size="2" name="qty" maxlength="2" value="<?php echo $item['Quantity']; ?>" onsubmit="this.value"/></td>
                <td><?php echo '$'.number_format($item['Price']*$item['Quantity'],2); ?></td>
                <!--td><input type="submit" name="update" value="Update" /></td-->
            </tr>
            <!--</form>-->
            <?php endforeach; ?>
        </tbody>
    </table>
    <p><input type="submit" name="update" value="Update" /></p>
</form>
When I debug my code and hover over the $_POST['prodId'] i will see the id of the last product. Any help will be appricated thanks.

Hey all not been on here for a few years, been out of work.  i am back and throwing ,myself straight into the deep end.

Is it hard to integrate a shopping cart into a website.  Any good example snippets of code to look at?  I have a little search but someone always seems to know a better one.  Why are almost all tutorials these days you have to pay for (times are getting hard ).

I have followed a shopping cart tutorial from this website.

http://v3.thewatchmakerproject.com/journal/276/

1. When you refresh the page it adds another item to the cart.

2. I would like to add an image of the products from a folder and the link of the images in the database.

Can some one please help. Urgently!

Thanks.
