// Simple products
add_filter( 'woocommerce_quantity_input_args', 'jk_woocommerce_quantity_input_args', 10, 2 );
function jk_woocommerce_quantity_input_args( $args, $product ) {
    $args['input_value'] 	= 2;	// Starting value
    $args['max_value'] 		= 80; 	// Maximum value
    $args['min_value'] 		= 2;   	// Minimum value
    $args['step'] 		= 2;    // Quantity steps
    return $args;
}

// Variations
add_filter( 'woocommerce_available_variation', 'jk_woocommerce_available_variation' );
function jk_woocommerce_available_variation( $args ) {
	$args['max_qty'] = 80; 		// Maximum value (variations)
    $args['min_qty'] = 2;   	// Minimum value (variations)
    return $args;
}

is there a way to have a default quantity field in the admin, so i can enter a default quantity for each product?

hello there
I have set minimum_quantity as a custom field to each product.
how can i set it to quantity input value?

do this for admin order item qty

// admin set qty input steps
add_filter('woocommerce_quantity_input_step', 'adminApplyArgsStep', 10, 2);

function adminApplyArgsStep($step, $product) {
if(is_admin()) {
$step = 0.01; // Has to be 0.01 to not conflict with step intervals and allow the admin to totally customize the quantity in backend
}
return $step;
}
