Set the starting value, maximum value, minimum value, and increment amount for quantity input fields on product pages.
|
|||
|
|
|

|

Add this code to your child theme’s `functions.php` file or via a plugin that allows custom functions to be added, such as the [Code snippets](https://wordpress.org/plugins/code-snippets/) plugin. Avoid adding custom code directly to your parent theme’s `functions.php` file, as this will be wiped entirely when you update the theme.
