Quantity Limits Module Question

[lesliekirk]

This code requires the quanlimits item to be assigned to all pages. It checks for exception errors and updates messaging in the mini-basket or on the basket page to direct the shopper to modify their cart. It removes the option to proceed to checkout. If someone manages to get past these checks, the module will catch them on the OSEL page. The site I did this on is using the Levels theme, so the code will have to be modified accordingly.

Thanks once again for helping to make this module work better. The store I'm working on uses the Minimum Quantities. I may need a little help if I can't rework what you did for the maximums. I'll share what I do - if it works.

[lesliekirk]

I don't believe this gets triggered until OCST is submitted. Not ideal...

OMG - how did I forget about this??? I'm trying to get this module working in another store and I COMPLETELY forgot about this mess. Why can't this module just work like the store owner thought it would (like the EP module did).

Thank you Leanne.!!! LOL the title of your post should have been Quantity Limits Module Answer

That would be great thank you!

I recently implemented this module on a store and thought the customer experience and messaging were dreadful, so I made several modifications to try to improve on it. I'll dig through and find what I did and post it here later today in case it's helpful to anyone.

[lesliekirk]

We're suffering from the Great Eastern Pollination and things are a little fuzzy.

We haven't had the attack of the yellow dust yet but I'm still recovering from the beginning of being turned into the bionic woman with a little bit of titanium inserted into my neck (doing so much better now) so I can relate to being in a fog.

[Ron Frigon]

based on the image from the docs.

This is a screenshot of:

If there are any validation errors it will take the customer back to the basket page with the errors which need to be fixed displayed.

I seem to remember having a support ticket for this but I can't find it.

https://www.miva.com/forums/forum/on...limits-by-miva

There are two places the module validates the min/max:

1. When the customer submits OCST (bill to ship to page)
2. On the AUTH action which is the final action to process the payment

If either of these fail it will redirect the custom back to the Basket page with an error message.

[mstella1]

I was under the impression it was built-in so we could add that on the BASK or OCST page based on the image from the docs.
min-max_checkout.png (2606×1698) (miva.com)

The error message shown is really all I needed to display and I figured since the error message I was hoping to see is in the png attached it would be pretty simple.

[Ron Frigon]

What does this do? QuantityExceptionList_Load_Line( line_id, exceptions var )

That will only display the Products Min/Max settings. You could probably create some template code to disable the checkout options.

Is this what you are referring to not working until you go to the OCST screen?

Referring to this from the docs:

Checkout Validation

Miva validates the quantity limits for the basket during the ORDR action. This is when the Bill To /Ship To fields are submitted (The OCST page). If there are any validation errors it will take the customer back to the basket page with the errors which need to be fixed displayed.

Sorry for not being too "wordy". We're suffering from the Great Eastern Pollination and things are a little fuzzy.

[lesliekirk]

To replace the EP Min/Max module use: https://apps.miva.com/quantity-limits.html

But, this module does not validate on BASK. It validates when OCST is submitted. I don't believe that can be changed.

I'm ready through the docs. They might be a bit misleading if you are finding the module does not work at the BASK level (or perhaps we are needing to work like the EP module)

Important: In order to use one of these functions on any page, the quanlimits item first needs to be assigned to that page. It does not get assigned to any pages by default upon install. Common pages to use it on would be BASK and PROD.

What does this do? QuantityExceptionList_Load_Line( line_id, exceptions var ) https://docs.miva.com/how-to-guides/...mits#functions

Is this what you are referring to not working until you go to the OCST screen?

I don't believe this gets triggered until OCST is submitted. Not ideal...

FYI - the EmporiumPlus Minimum and Maximum Quantity module supposed to work on the BASK screen. See item #2 of the editing requirements https://www.emporiumplus.com/v5/cim_qmin.htm

Ron, have to figured out a way to replace the module's functionality?

(Sorry for all the "words" - trying to make this post searchable)

[Ron Frigon]

I discovered the Min/Max Quantity module either isn't working at the BASK screen

I don't believe this gets triggered until OCST is submitted. Not ideal...

Miva validates the quantity limits for the basket during the ORDR action. This is when the Bill To /Ship To fields are submitted (The OCST page).

[delcorsets]

Also jumping on for the ride.. we have quite a few EP modules as well that I’m finally getting around to replacing…
