Hey.
I need to write a function that would be able to set the minimum quantity of an item to add to the cart, and the step of increasing this quantity.
I wrote it:

// Adding and displaying additional product quantity custom fields
add_action( ‘woocommerce_product_options_pricing’, ‘additional_product_pricing_option_fields’, 50 );
function additional_product_pricing_option_fields() {
$domain = “woocommerce”;
global $post;

echo ‘

‘;

woocommerce_wp_text_input( array(
‘id’ => ‘_input_qty’,
‘label’ => __(“quantity”, $domain ),
‘placeholder’ => ”,
‘description’ => __(“Quantityof items in a package”, $domain ),
‘desc_tip’ => true,
) );

woocommerce_wp_text_input( array(
‘id’ => ‘_step_qty’,
‘label’ => __(“Step”, $domain ),
‘placeholder’ => ”,
‘description’ => __(“Step of packing units when ordering”, $domain ),
‘desc_tip’ => true,
) );

}

// Saving product custom quantity values
add_action( ‘woocommerce_admin_process_product_object’, ‘save_product_custom_meta_data’, 100, 1 );
function save_product_custom_meta_data( $product ){
if ( isset( $_POST[‘_input_qty’] ) )
$product->update_meta_data( ‘_input_qty’, sanitize_text_field($_POST[‘_input_qty’]) );

if ( isset( $_POST[‘_step_qty’] ) )
$product->update_meta_data( ‘_step_qty’, sanitize_text_field($_POST[‘_step_qty’]) );
}

// Set product quantity field by product
add_filter( ‘woocommerce_quantity_input_args’, ‘custom_quantity_input_args’, 10, 2 );
function custom_quantity_input_args( $args, $product ) {
if( $product->get_meta(‘_input_qty’) ){
$args[‘input_value’] = is_cart() ? $args[‘input_value’] : $product->get_meta(‘_input_qty’);
$args[‘min_value’] = $product->get_meta(‘_input_qty’);
}

if( $product->get_meta(‘_step_qty’) ){
$args[‘step’] = $product->get_meta(‘_step_qty’);
}

return $args;
}

But it doesn’t work right.
The item card says 25, but when you click on “add” only 1 item appears in the cart.
However, if I first press “+” or “-” on the quantity selection buttons, and only then add the product to the cart, then 25 will be added.

Hello,

Take our apologies but additional customization is not included in theme support https://themeforest.net/page/item_support_policy
If you need help with additional customization you can submit request to WPKraken team here.

Also, you may try third-party plugins to implement things you need, for example, check if this one suits your needs https://wordpress.org/plugins/woo-min-max-quantity-step-control-single/ , https://wordpress.org/plugins/product-quantity-for-woocommerce/

Regards
