Change the sold out status from 0 in stock to -1

[PatF]

This may sound a bit bizzarre but I have a reason for this.

In Admin-Config-Stock When Show Sold Out Image instead of add to cart is selected it means that any item with a stock level of 0 or under has the add to cart button disabled.

Would anyone have any idea where I could amend the code so that a stock level of 0 will still allow add to cart and checkout but anything beneath this ie -1,-2 etc would be blocked. ?

Thanks in advance

open includes/functions/functions_general.php

search for:

case ($button_check->fields['products_quantity'] <= 0 and SHOW_PRODUCTS_SOLD_OUT_IMAGE == '1'):

replace by:

case ($button_check->fields['products_quantity'] < 0 and SHOW_PRODUCTS_SOLD_OUT_IMAGE == '1'):
