Qty for Item's Status to Become Out of Stock - Problem with mass upload

Question

I am using a php script which works great with updating stock but when a simple product is 1 or below stock availability isn't changing to "out of stock". I have "Qty for Item's Status to Become Out of Stock" at 2. I have to go into the product and click save then it will change to out of stock.

This there faster way or am i missing something easy? code below

Answer 1

your if statement would override your stock settings.

$isInStock = $newQty > 0 ? 1 : 0;

$stockStatus = $newQty > 0 ? 1 : 0;

so it would only set stock to out o' stock if stock == 0. then as you said you need to go into the admin and save the item to trigger your stock rules.

if you reindex your data base after running this script it could possibly correct your stock issue?

otherwise set you if statement to

$isInStock = $newQty <= 2 ? 0 : 1;

$stockStatus = $newQty <= 2 ? 0 : 1;
