PHP - Advice Using Google Checkout

I could use some suggestion on how to model the Checkout Process for my e-commerce site.

As I see it, when a person "checks out" there are 5 steps...

1.) Create an Account/Log-In
2.) Enter Addresses
3.) Choose Shipping Options
4.) Enter Payment Details
5.) Review & Place Order

I'm trying to avoid having gigantic "God classes" and struggling to figure out how to abstract things in good OOP terms.

My Head First: Design Patterns book talked about the "State Pattern" and I'm wondering if that might be a good approach?   

Maybe each of the 5 steps above could be a "state" in the Checkout Process?

What do you think?

Hey guys!

I need your help with some issues.
Firstly, I have an own website with a database filled with products, and also a template page(template.php) for each product. Problem is that I don't know how to generate each product from the database in the template.php file using their id from the database. How can I do this?

Second problem, I got an own checkout and I don't know how to redirect the customer to a "thank you for buying" page after clicking "Finish Order". It sends the customer to a white page where it says: "Thanks for buying!".

Third and last thing, do you guys know where can I find a php checkout template to follow?

Thanks in advance for your answers!
Cheers!

Hi all,

I am looking to integrate Paypal Express checkout on my site and have been working with the API today.

I have got the code working in a static state with predefined payment amounts but I am having trouble making this dynamic.

When you first submit a request to set up an express checkout you send the payment amount along with it. The paypal server then makes the checkout and the user is redirected to the paypal site to login and authenticate. From here they click to be redirected back to my site where I have a pay button which when clicked submits the final request to confirm the payment.

I am sure there must be a simple solution to this because so many people use paypal already but when you submit the final confirmation request, you have to send the payment amount again, but because the page redirects onto the paypal page inbetween, I can't use a session variable to store the amount. How have other people overcome this?

Thanks

Hi, I have set up a simple shopping cart with a coupon code function.

I am having an issue with the Update basket and Checkout buttons, when you click update basket it loads the /checkout/ page but then redirects back to the /cart/ after a couple of seconds when it should just load a new page saying 'Shopping basket successfully updated' - also, when you click the proceed to checkout button it does the same, loads the /checkout/ page (which is correct) but then redirects back to /cart/.

Here is the php code I have setup:

// View Shopping Basket

if (!isset($_GET['action']) || $_GET['action'] == 'products') {
// Check if the shopping basket is empty

if ($cart->get_num_products(session_id()) <= 0) {
output('Your shopping basket contains no products!');
} else {
if (!isset($_POST['submit'])) {
$tpl->set('body', $body->fetch('index.tpl.php'));
} else {
$cart->update_contents(session_id());
output('Shopping basket successfully updated!');
redirect('/cart/', 2);
}
}
}

// Add Product to Cart

if (isset($_GET['action']) && $_GET['action'] == 'add_product') {
$product_id = isset($_GET['product_id']) && is_numeric($_GET['product_id']) ? (int) $_GET['product_id'] : 0;
$cart->add_product(session_id(), $product_id, 1);

output('Product successfully added! Please wait while we redirect you to your shopping basket.');
redirect('/cart/', 2);
}

if (isset($_SESSION['coupon_code'])){
unset($_SESSION['coupon_code']);
}

if (isset($_POST['go']) && $_POST['go'] != ''){
$_SESSION['coupon_code'] = $_POST['coupon_code']; 
header("location:/checkout/");
}

Here is the HTML for the form:

Code: [Select]
<h1>My Basket</h1>
<form method="post" action="/cart/">
<input type="hidden" name="submit" value="Update" />
    <input type="hidden" name="go" value="true" />
<table class="tableGrid">
<tr>
<th width="10%"><strong>Remove:</strong></th>
<th width="60%"><strong>Product Name:</strong></th>
<th width="10%"><strong>Price:</strong></th>
<th width="10%"><strong>Qty:</strong></th>
<th width="10%"><strong>Total:</strong></th>
</tr>
<?php foreach ($GLOBALS['cart']->get_contents(session_id()) as $product) { ?>
<tr>
<td align="center" width="10%"><input type="checkbox" name="delete<?php echo $product['cart_id']; ?>" value="yes" /></td>
<td width="60%"><a href="<?php echo get_url('/products/', $product['category_id'], $product['product_id'], $product['product_name']); ?>"><?php echo $product['product_name']; ?></a> <span class="important">* <?php echo $product['stock'] >= $product['quantity'] ? 'Available' : 'Not Enough In Stock'; ?></span></td>
<td width="10%" align="center"><?php echo get_price($product['price']); ?></td>
<td width="10%" align="center"><input type="text" name="quantity<?php echo $product['cart_id']; ?>" value="<?php echo $product['quantity']; ?>" maxlength="10" style="width: 30px;" /></td>
<td width="10%" align="center"><?php echo get_price($product['price'] * $product['quantity']); ?></td>
</tr>
<?php } ?>
</table><br />
        <div class="main_box" style="height: 26px;">
        <div style="float: right;">Subtotal: <strong><?php echo get_price($GLOBALS['cart']->get_cart_total(session_id())); ?></strong></div>
<div style="float: left;">
<label><strong>If you have a promotion voucher code please enter it he </strong></label>
<input type="text" name="coupon_code" id="coupon_code" value="" />
</div>
        </div><br />
<div align="center"><input type="image" src="<?php echo '/' . $config['image_path']; ?>button_cart_update.gif" border="0" alt="Update Shopping Basket" /> <a href="/shop-11/"><img src="<?php echo '/' . $config['image_path']; ?>button_continue.gif" border="0" alt="Continue Shopping" /></a> <input type="image" name="checkout" src="<?php echo '/' . $config['image_path']; ?>button_checkout.gif" border="0" alt="Proceed to Checkout" /></div>
</form>
If anybody can spot whats wrong I would really appreciate it. - It is probably something so simple but I am finding ti quite frustrating.

Thanks,

Paul

Hi,

I'm building a webshop and im stuck at the checkout.

I'm using this Shopping Cart class http://www.webforcecart.com/manual.html
The cart is stored as an object in $_SESSION[cart].

This method
Code: [Select]
print_r($cart->get_contents());would get this as output:
Array ( => Array ( [id] => 7 [qty] => 1 [price] => 11.00 [info] => Test [subtotal] => 11 ) [1] => Array ( [id] => 6 [qty] => 2 [price] => 19.00 [info] => White 0 [subtotal] => 38 ) )


In the table Order I would like to store
order-id
customer-id
total products
total quantity
total price
date

In the table Orderrow I would like to sto
order-id,
product-id,
product-name,
quantity,
price,
subtotal

I know i can get the order-id with the function mysql_insert_id() but how can i store each product in the array with their info in the table Orderrow?
Or is there a better way to do this? please advice me, thank you.

Dear forum,
my name is Dominic from germany.

I`m always trying hard, but after 5 hours I really need some help in php coding.

My problem deals with my checkout page for woocommerce.

At the moment, my legal terms are above the total-order-table where u can find the booked product, order-subtotal, order-total and tex-total.

But I need to display the legal terms under my total-order table. I need the terms directly above the "Buy now" button.

Do you guys know which file to modify ? I tried everything. Nothing worked for me.

You will find a picture in this post. There you can see my problem. 

Would be pretty nice if you can give me some information.

Kind regards,
Dominic Lindner

Hello

I use this code to display popup login when user to clicked on a "proceed to checkout" button in the cart page (woocomerce)

<?php
function woocommerce_button_proceed_to_checkout() {
       $checkout_url = WC()->cart->get_checkout_url();
       ?>
       <div <?php echo mf_get_option( 'login_reg_popup' ) ? 'data-toggle="modal" data-target="#login-modal"' : null; ?>>
       <a class="checkout-button button alt wc-forward" href="<?php echo ! mf_get_option( 'login_reg_popup' ) ? wc_get_page_permalink( 'myaccount' ) : '#'; ?>" class="checkout-button button alt wc-forward"><?php _e( 'اقدام به پرداخت', 'woocommerce' ); ?></a>
       <?php
}

 

But after login, I want the user to be redirected to the "checkout" page if it is on the cart page
Otherwise redirect to your current page wherever you are logged in

I found the following code but I couldn't put it in the code above
Thank you for helping me with your kindness

<?php

//redirect to your "current" page
wp_redirect( $_SERVER["HTTP_REFERER"] );


// redirect to the "checkout" page
function wpse_131562_redirect() {
    if (! is_user_logged_in()
        && (is_woocommerce() || is_cart())
    ) {
        // feel free to customize the following line to suit your needs
        wp_redirect(site_url('checkout/'));
        exit;
    }
}
add_action('template_redirect', 'wpse_131562_redirect');

 

Hello. I can use some help in figure out how to implement a "transaction".

I am building an e-commerce site where people buy subscriptions to online content.  When a person subscribes for the first time, the following things need to happen...

1.) Create a Member record

2.) Create a TOS record

3.) Create an Order record

4.) Create an Order Details record

5.) Submit payment details to Card Processor

6.) Receive the response from the Card Processor  (Hopefully a "Pass")

7.) Display an "Order Confirmation" page.

8.) Send out an "Order Confirmation" e-mail to serve as a 2nd receipt.

9.) Send out an "Account Activation" e-mail

My original plan was to wrap all of those 9 steps into a "transaction", so that if any of those steps failed, then the user would get a message during checkout like, "Sorry, your checkout could not be completed.  Please contact Customer Service."

However, I am also wondering if maybe that is too rigid?

What I don't want is a scenario where all of the records are created, but let's say the payment fails because the user is over his/her credit limit, and then I have an issue where a new "Member" has been created, but in essence I have an "orphan" because they cannot go back and try to re-register with another credit card because they are now an existing Member.

Even something as seemingly innocuous, like the "Account Activation" e-mail not being sent, would create havoc.

At  the same time, I don't want things so rigid that it backfires. 

Any thoughts on this?

 

So here's my problem I'm not sure how to approach this:

I have a table with user_items which are stored together separated by commas.
Code: [Select]
13,12,11,9,27,15,16,22,21,23,24,26,29,30,31,32,33
Now, I have a script where the user is in a trade and I want to verify the item they are trying to trade, but is there an alternative other than grabbing all of that users' items and checking that one item with all of the records?

I've tried using
Code: [Select]
SELECT * FROM MYTABLE WHERE user_item_id IN(33)
As an example to see if it will pull the rows with that ID.  It didn't seem to work, am I doing it wrong? if so, forgive me. Any suggestions/help? The main problem is I don't want to have to explode that data and use a foreach to check that one item against all of that users items, as they could have well over 500.

In short i want to use the following code below, when someone selects there option and submits it, it would bring up details from the database on this user from the selected table, can you explain what it would be called doing this so i can look it up, Sorry to be a pain, Cheers.

Code: [Select]
<select name="target2" id="target2">

    <option value=""></option>

  <?php

  $sql = "SELECT player_id, friend_id, name, is_active FROM contacts as c JOIN players as p ON c.friend_id = p.id WHERE c.player_id = $playerID AND is_active = 1 ORDER BY name ASC";

  $que = mysql_query($sql) or die(mysql_error());

  while($list = mysql_fetch_array($que)) {

  ?>

  <option value="<?php echo $list['friend_id'] ?>"><?php echo $list['name'] ?></option>

  <?php } ?>

  </select>

Hi, basically i have data in my database i want to represent as cash, i currently put the dollar sign infront of each echo which is fine, but how would i go about adding , to the php code itself as you cannot do this from the sql database..

for those of you who don't know i am creating a piece of forum software called ASF. Ive done it by myself so far but as it grows i find it harder to write the code and keep organised. my code is a mess and things arent done the way they should be. So if anyone can give me advice or wants to help i could post some of the files for download. Even if you just want to have a look and let me know waht you think.

Thanks
Carl

Hi all,

I am looking as a pet project to develop a review site, with the info stored in a database by id and the information grabbed bet get id and then displayed on a dynamic page, eg review.php?id=1

My question is this, if i throw keywords into the mix for each review, will search engines cache a review like this? Or would I need static pages for google etc to find the info?

Thanks

Hello, can someone please advice me on what scripts I will need to accomplish the following.

I want users to be able to login to their personal page, on there will be items such as pdf files, jpeg files etc, that they will be able to download.

Are there any free scripts out there that can do this, that anyone knows of? I don't mind paying if its a cheapish script for one of you to make for me, but money is a bit tight at the moment so a free script would be my 1st choice...

Thanks for all your help
