Buy button on a product detail page

• First argument: entry id or slug (variant sub-entry for options)

• Third: quantity (optional, default 1)

Lowest price on a product detail page

On a detail URL (?collection=products&slug=…), slug resolves to the current entry:

<p>€{commerce_price_from slug products}</p>

Or pass the commerce field directly (variants, custom field slugs):

<p>€{commerce_price_from {'commerce'}}</p>
<p>€{commerce_price_from variant.commerce}</p>

The tag returns a number with a dot decimal (for example 6.50). Add your currency symbol and locale formatting in HTML/CSS.

Variants (sub-collection)

On a product detail page (URL has ?collection=products&slug=…):

{for each entry in 'variants' of 'products'.current ordered by order}
  <div>
    <h3>{title}</h3>
    <a href="{commerce_buy_url slug products 1}">Buy</a>
  </div>
{endfor}

Use the variant’s own slug/id in commerce_buy_url when that row is the sellable unit.
