Stocks by attributes

[kuroi]

When customers place an item in their cart and then view the cart it tells the user that the item is no longer in stock and they must change either the amount or size before checking out.

It would be preferable that the module removes that attribute from the product detail page so that the customer can not add the product to the cart in the first place.

Indeed it would.

When there is only one attribute available it's relatively straightforward to link stock to an attribute on the product page and either display it or suppress it.

With two or more attributes on a product, it gets more difficult as the cart needs some knowledge of the selections being made by the customer. As the mod has its roots back in osCommerce and long before AJAX had been conceived, it wasn't really designed for this. But a few people have done things in this direction. Since Zen Cart 2.0, with attribute stock, is imminent, I have no plans to do further work on this mod, though it being open source, anybody else is welcome to do so.

So I assumed the only real reason to use THIS mod was to track inventory for yourself, not really prevent items that are out of stock from being ordered.

If properly installed, then the option to prevent customers from checking out is a key feature of the attribute stock mod. This can be set by tweaking the settings on the Admin > Configuration > Stock page.

Well I guess mine isn't installed correctly because I set the option to 'false' and it's still letting me checkout Not sure where I could have gone wrong though...

I installed (or believe I did correctly) the 'Stock by Attributes' mod. And things seemed to work. BUT, I wanted to make sure that a person couldn't check out with an unavailable item in their basket. So I made sure the option in the configuration -> stock 'Allow Checkout' was set to FALSE but this didn't do anything as I was able to still checkout.

So my next plan was to try and implement the 'make the specific stock item disappear from the drop down list when the stock for THAT attribute is 0.' And I followed directions and believe I pieced together the code as well as possible, but since nothing has changed, I have to assume that I messed up somewhere.

Since I have gone back and forth and from 'fix' to 'fix' I have no clue where I may or may not have made a mistake. Sooooo....I figure the best thing to do is reverse the entire process but since I've never reversed anything else, I have no idea the proper way to do this.

Can anyone help???????????????????????????

OK now I'm truly perplexed. After going through the various files I thought I figured out that the header_php.php file in the 'checkout shipping' folder had somehow not been updated with your mod. So I then added it and things worked! It wouldn't allow me to checkout if there was an out of stock item in my cart. However...when all items in my basket were in stock, when I clicked to go to the checkout, the page just returned a completely blank header_php page. So I panicked because now I've really screwed things up so I went back and replaced that file with the original one...but it was still returning the blank page. So I panicked more and deleted the header_php all together and now EVERYTHING works??? This is great except that it makes no sense and I'm worried it's going to cause a problem...any idea why this is happening?

@laurenjj

It is sounding as though key files hadn't over-written your originals and this is why customers were able to checkout even when the attribute stock was at zero. This is far and away the most common installation problem.

I'm afraid that you explanation of the current state of your site cannot be completely accurate, since without the header_php file, the checkout_shipping page simply cannot function, or even exist.

I would suggest a two pronged approach to sort this out.

1. Re-install the attribute stock module and check each file listed in the readme to ensure that the datestamp confirms that it has been updated (no need to re-run the database patches)

2. If you still have a blank page problem, then install the debug utility to track down the specific cause.

I have installed SBA 4-7 and after some difficulty have got it working fine, I thought, until I tried to add another attribute to a product that was not associated with stock quantity.
I am selling skis and I want to add attributes that will add on a cost for choosing to have the bindings mounted. I created an attribute with the check box style and two values and used absolute prices for them. On my products page only the attribute's name shows up - No values and no check boxes. When I look at the preview from the product attributes controller it shows up correctly.
I have a suspicion that SBA may have something to do with this. Any ideas?
I am using the latest version of ZC.

New info on the previous post:
I went into the Products with Attributes Stock console to see what was up there with the product I had tried to add the second set of attributes to and found that the quantity associations I had made to the sizes were gone. When I tried to use the [FONT="Fixedsys"]add quantity for product variant[/FONT] the new attribute (which needs no quantity) was there along with the sizes. When I tried to reestablish a quantity to one of the sizes I got this error message:

att: 17,39|38
Warning: Cannot modify header information - headers already sent by (output started at /home/bootdo5/public_html/shopcart/admin/products_with_attributes_stock.php:193) in /home/bootdo5/public_html/shopcart/admin/includes/functions/general.php on line 21

Once you install this mod is it going to require a quantity for any attribute? How do you handle something like sizes + colors?
I'm not sure where to go from here other than removing the second set of attributes until I get an answer on this.

I created an attribute with the check box style ...Any ideas?

Just a thought: try changing the check box attribute to a drop down, add stock in PWAS, and see what happens.
