Stock Level for Variants

Okay, so here's the issue. I'm surprised no one has run into this. My client sells hats, but the product could be anything like t-shirts. Each hat style has a color variant.

Well, I want to display if the product is in stock or not ... problem is, the client tracks the products by variant. Is there a way to show if the product is in stock by getting a count of all the variant stock numbers COMBINED?

In theory, if I count stock on individual variant, then the stock_level will always read zero ... if I set it to 1, then even if the client sells out all of variants, the stock level will still read 1 and show that we have that item in stock.

I feel like there's a disconnect between count stock on individual variant and the stock_level for the item as a whole. If you track count stock on individual variant then the stock_level should be auto-calculated as such.

I thought of a hack, in the template looping though all the variants and gathering their individual stock numbers and adding them together, but as far as I can tell, theres no way to do math inside a template.

Even then, if that did work, this would still fail or at least not match:

perch_shop_products([
        'filter' => 'stock_level',
        'match' => 'gte',
        'value' => '1'
    ]);

correct me if I'm wrong on all this ...

so I found a hack for the first issue ... on the actual product page, I do this:

$count = 0;
$vars = perch_shop_product_variants($prod, [
    'skip-template' => true,
    'return-html' => false,
]);

foreach ($vars as $key => $value) {
    $count += $value['stock_level'];
}

PerchSystem::set_var('full_stock', $count);

perch_shop_product($prod, [
    'template' => 'products/list_individual.html',
    'variants' => true,
]);

obviously, passing the newly calculated stock number as a variable and calling it with <perch:shop id="full_stock" type="text" />

but I don't think this will work for a product listing page, where several products are listed and I call them all at once with perch_shop_products ... unless I can pass arrays into the templates as variables ... I guess I could try, but I don't see anything like that in the docs.

On the listing page you'd need to use an each callback function to do the above.

I just want to chip in and say that I've had the same issue, and also agree with the statement; "If you track count stock on individual variant then the stock_level should be auto-calculated as such." The stock_level should also then be disabled I feel.

Would be a nice little update in a future update.
