Update and Remove Not Working in Shopping Cart

poplarman · February 8, 2013

I've just recently noticed (don't know when it started) that the update and remove links in the shopping cart don't update. I'm using v.2.3.3 at http://www.noahs-arc.org.uk/shop/catalog/shopping_cart.php

The "add to cart" is also not working properly.

Suggest you look at the file /includes/application_top.php and look for switch ($HTTP_GET_VARS['action']) {

as this block of code is what controls all these "actions".

Have you made any changes to the shop in this area?

poplarman · February 8, 2013

I've carried out more testing and it now seems that I'm experiencing delayed updates. If I visit Checkout and return a couple of times the figures seems corrected - weird. Can anyone help?

Hi Bob,

Looks like a fairly new install try replacing your

1: catalog/ includes/classes/shopping_cart.php

2: catalog/shopping_cart.php

and lastly

3: catalog/ includes/application_top.php

with original files one at a time in that order and checking in shop each time to try and localize the BUG :) .

Regards

Joli

Burt quicker than me :thumbsup:

Suggest you look at the file /includes/application_top.php and look for switch ($HTTP_GET_VARS['action']) {

as this block of code is what controls all these "actions".

My code looks like this:

// set the HTTP GET parameters manually if search_engine_friendly_urls is enabled

if (SEARCH_ENGINE_FRIENDLY_URLS == 'true') {

if (strlen(getenv('PATH_INFO')) > 1) {

$GET_array = array();

$PHP_SELF = str_replace(getenv('PATH_INFO'), '', $PHP_SELF);

$vars = explode('/', substr(getenv('PATH_INFO'), 1));

do_magic_quotes_gpc($vars);

for ($i=0, $n=sizeof($vars); $i<$n; $i++) {

if (strpos($vars[$i], '[]')) {

$GET_array[substr($vars[$i], 0, -2)][] = $vars[$i+1];

} else {

$HTTP_GET_VARS[$vars[$i]] = $vars[$i+1];

}

$i++;

}

if (sizeof($GET_array) > 0) {

while (list($key, $value) = each($GET_array)) {

$HTTP_GET_VARS[$key] = $value;

}

this block I think!!

// Shopping cart actions

if (isset($HTTP_GET_VARS['action'])) {

// redirect the customer to a friendly cookie-must-be-enabled page if cookies are disabled

if ($session_started == false) {

tep_redirect(tep_href_link(FILENAME_COOKIE_USAGE));

}

if (DISPLAY_CART == 'true') {

$goto = FILENAME_SHOPPING_CART;

$parameters = array('action', 'cPath', 'products_id', 'pid');

} else {

$goto = basename($PHP_SELF);

if ($HTTP_GET_VARS['action'] == 'buy_now') {

$parameters = array('action', 'pid', 'products_id');

} else {

$parameters = array('action', 'pid');

}

switch ($HTTP_GET_VARS['action']) {

// customer wants to update the product quantity in their shopping cart

case 'update_product' : for ($i=0, $n=sizeof($HTTP_POST_VARS['products_id']); $i<$n; $i++) {

if (in_array($HTTP_POST_VARS['products_id'][$i], (is_array($HTTP_POST_VARS['cart_delete']) ? $HTTP_POST_VARS['cart_delete'] : array()))) {

$cart->remove($HTTP_POST_VARS['products_id'][$i]);

} else {

$attributes = ($HTTP_POST_VARS['id'][$HTTP_POST_VARS['products_id'][$i]]) ? $HTTP_POST_VARS['id'][$HTTP_POST_VARS['products_id'][$i]] : '';

$cart->add_cart($HTTP_POST_VARS['products_id'][$i], $HTTP_POST_VARS['cart_quantity'][$i], $attributes, false);

}

tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));

break;

poplarman · February 8, 2013

Joli - thanks again. I've replaced the modules and get the same results. I'm guessing at the moment that this could be a server-side problem as the Cart does seem to update in 'delayed' mode. I'll try again soon.

♥joli1811 · February 8, 2013

Yes

noticed that as well but have the feeling it is more a file issue rather than server not sure just my opinion.

Joli

poplarman · February 8, 2013

Thanks again. Here's the strange thing. 1) Add an item to Cart; 2) Change Quantity - change doesn't show; 3) Click on Checkout and number of items in Cart (top of screen) has changed. 4) Flip between Cart and Checkout and eventually item qty shows.... any more ideas please?

poplarman · February 8, 2013

@@joli1811 - are these quantities held by Cookie or MySQL at this stage?

♥joli1811 · February 8, 2013

should be in MySQL customers_basket at this stage. you should be able to see in phpmyadmin

poplarman · February 8, 2013

OK - will monitor

poplarman · February 8, 2013

@@joli1811 - Okay, I can confirm that the quantities in the basket are updated immediately to MySQL - so why the delay in updating the view? Cache problem maybe? Just guessing - I don't know the software sufficiently.

♥joli1811 · February 8, 2013

No very unlikely it is file problem I think more broken code.

I do not see as a delay but depends from which page / file you view the shopping basket.

poplarman · February 8, 2013

I do not see as a delay but depends from which page / file you view the shopping basket.

True - but if I continue to flip between Checkout and Cart, the Cart eventually shows correct value.

♥joli1811 · February 8, 2013

so back to checking the files which are responsible for the output.

♥joli1811 · February 8, 2013

Seems to be session/cookie not being carried over the information is in the database just not being outputted on the shopping cart

configure.php possibly check the

define('HTTP_COOKIE_PATH', '/');

define('HTTPS_COOKIE_PATH', '/');.

sometimes

define('HTTP_COOKIE_PATH', 'www.noahs-arc.org.uk');

define('HTTP_COOKIE_PATH', '.noahs-arc.org.uk');

define('HTTP_COOKIE_PATH', 'noahs-arc.org.uk');

Setting depends on server and configure so x 4 possibility's

Running out of ideas here might be a big bug hunt :D

regards

Joli

PS: cache files are in catalog/includes/work check and empty.

poplarman · February 8, 2013

Current values: define('HTTP_COOKIE_PATH', '/shop/catalog/'); define('HTTPS_COOKIE_PATH', '/shop/catalog/');

poplarman · February 9, 2013

Well - overnight it seems to be back to normal. I've made no changes so we won't understand the cause. Thanks for all your efforts though.@@joli1811

Well nice to see working again probably the internet teufel :devil: at work again.

Weird thing... I am having the same problems...it's kinda driving me nuts... php debug mode doesn't produce anything.. and it's adding/removing definitely delayed.. as is the adding itself

From the product page itself - add - shows empty card...

ctrl -f5 et voila!

BTW I installed oscommerce via my hosting company - if I copy and paste a brand new app top file I get alot of warnings (from the download page here).

Help!!

June 4, 2013

I've reinstalled the whole thing - not from the hosters admin panel, but the package from the site, and problem still exists.. so it really seems to be a hosting thing. I've send them an email...
