This is a simple mod that takes 2 minutes.
All we are doing is pulling the quantity from the database into a data parameter,
Then switching on the add to cart buttons of that value is not zero.

First we pull the quantity value from the database and into a data parameter:
In file:/catalog/controller/product/product.php
Find:

Code: Select all

if ($product_info['quantity'] <= 0) {

Add this line before it:

Code: Select all

$data['stockb'] = $product_info['quantity'];

Save and close the file.

Then we switch the buttons on and off depending on if the value is zero or not with a simple 'if' statement
In file /catalog/view/template/product/product.twig
Find:

Code: Select all

<button type="submit" id="button-cart" class="btn btn-primary btn-lg btn-block">{{ button_cart }}</button>

Add this line before it:

Code: Select all

{% if stockb > 0 %}

Add this line after it:

Code: Select all

{% endif %}

I would have posted it in the OC4 section but it looks like I don't have permissions to post there.
Cheers.
