PHP - Quantity Drop-down Problem

Hi All

This is not really somthing the paypal developers answer as its general php so thought I would ask on here

Basically, have 3 products with 3 item numbers (101,102,103)

I have set up if, elseif statements to insert into database depending on the item number. This works fine.

However i now want to integrate the quantity. As the purchase will set up a user, i want the inserts to be dependent on the quantity purchased, so if 3 courses are purcased under item number 101 then it sets up 3 user accounts (inserts in to users x3) with the username with an increment of for example test@test.com-1

Can someone pointe me in the correct direction please?

Here is the script(including the mail script at bottom but ignore)

Code: [Select]
$fecha = date("m")."/".date("d")."/".date("Y");
$fecha = date("Y").date("m").date("d");

//check if transaction ID has been processed before
$checkquery = "select txnid from paypal_payment_info where txnid='".$txn_id."'";
$sihay = mysql_query($checkquery) or die("Duplicate txn id check query failed:<br>" . mysql_error() . "<br>" . mysql_errno());
$nm = mysql_num_rows($sihay);

if ($nm == 0){

//execute query
if ($itemno == "101"){

How can i use without quantity [Product Name, Price, total, Action] i tried lot fail again and again. I am learning stage in PHP, any help pls welcome.

Hello this may sound a little confusing. I recently made a fake website using this phpacademy tutorial I found. Anyways it has an quantity stock what I mean by this is
let's I have 3 copies of a video game an a person set they quantity for 2 of the 3 copies and proceed to the checkout through paypal payment successful okay.

My question is: How can I go about sending the quantity stock back to the database to subtract 2 from 3 to be left with 1 copy of the game in the quantity section after a successful purchase?

Hi, could you please help me with an issue? 

I want to hide the price for one product in the WooCommerce emails that I send to the clients Only If the quantity of a product is over 50. For all the other items I want the price to be shown. For example, the order has 2 products, one with 30pcs quantity that displays price, and the other with 120pcs quantity but with a text 'some text' instead of the price.

I modified the email-order-items.php, <?PHP echo $order->get_formatted_line_subtotal($item); ?>  But, It's not working. I'm sure is this line but I don't know how to continue and I'm stuck. 

Thank you so much.

Hi Guys

I have a shopping cart where the quantity refresh keeps defaulting to one (i.e. you change it from one to ten and the page refreshes and defaults back to one). This is the automatic refresh, not clicking a button.

We have lots of other carts using almost the exact same code and they work fine. I can swap over the code in the html page for something more basic and it works. I have compared the basket.php files (both in the lib folder and the html folder - we are using smarty templates) with working sites and they are identical.

Here is the basket.html code:

Code: [Select]
<form action="basket.html" method="post" name="update" id="update" >
<table class="basket-table" cellpadding="0" cellspacing="0">
<tr>
<th width="64">Item</th>
<th width="285" class="basket-desc">Item Description</th>
<th width="47">Quantity</th>
<th width="82">Price</th>
<th width="53" class="no-rb">Remove</th>
</tr>
<!--{section name=c loop=$basket.products}-->

<td class="basket-desc"><a href="/category/<!--{$basket.products[c].categoryLink}-->/product/<!--{$basket.products[c].link}-->/<!--{if $basket.products[c].hasSiblings}-->?option=<!--{$basket.products[c].productOptionId}--><!--{/if}-->"><!--{$basket.products[c].prodtitle}-->&nbsp;<!--{if $basket.products[c].hasSiblings}--><!--{$basket.products[c].optiontitle}-->:<!--{$basket.products[c].title}--><!--{/if}--></a></td>

<input type="hidden" name="formAction" value="update"/>
<a href="/checkout.html" class="btn-continue"><img src="/images/btn_continue.gif" alt="continue" title="Continue To Checkout" /></a>
</form>
The other refreshes work (region and coupon).

I think the problem is in the line:

Code: [Select]
<input name="quantity<!--{$smarty.section.c.index}-->" id="<!--{$basket.products[c].prodtitle}-->" value="<!--{$basket.products[c].quantity}-->" maxlength="3" onchange="this.form.submit()" type="text" />
this is the basket.php from the html folder:

Code: [Select]
<?php

require_once('../lib/config.php');
require_once(LIBDIR . "app_top.php");
require_once(LIBDIR . "region.php");


$params = processParams();

$region = new region_collection();

$clist = $region->getRegionList();

Here is a snippet from the basket.php file in the lib folder.I hope I have grabbed the relevant bit (have attached the full file just in case).

Code: [Select]
/**
* adds product to the basket
* @params int $option the product option id
* @params int $quantity the quantity of the products to add
  */
function add($product, $option, $quantity) {

if (!isset($option) || !is_numeric($option)) {

//trigger_error("No options selected");
return false;
}

if (!isset($quantity) || !is_numeric($quantity) || $quantity < 1 ) {

trigger_error("No quantity selected");
return false;
}

if (!isset($product) || !is_numeric($product) || $product < 1) {

trigger_error("No product selected");
return false;
}

/**
* if the session var doesn't already exist recreate it
*/
if (!isset($_SESSION['basket']) || !is_array($_SESSION['basket'])) {

$_SESSION['basket'] = array();
$_SESSION['basketinfo'] = array();
}

sort($_SESSION['basket']);

Any help the community can give would this would be much appreciated.
