Remove WooCommerce Cart Condition (Minimum Amount of a Product) - php

Question

i'm a bit stuck for this.. i'm trying to remove a condition whenever the user adds a specific product, in this case a box of wines
So when i add a bottle of wine there's a minium amount condition so you have to add 3, but when you add a box the condition must be removed
add_action('woocommerce_after_cart_contents', 'box_special_function', 1, 1);
function box_special_function()
{
// getting cart items
$cart = WC()->cart->get_cart();
$terms = [];
// Getting categories of products in the cart
foreach ($cart as $cart_item_key => $cart_item) {
$product = $cart_item['data'];
$terms[] = get_the_terms( $product->get_id(), 'product_cat' );
}
// Cycling categories to find if there is a box inside of the cart
foreach($terms as $term => $item){
foreach($item as $key){
if($key->name == "BOX"){
// The only thing i did is to remove notices (which doesn't even work .-.)
$notices = WC()->session->get('wc_notices', array());
foreach($notices['error']){
wc_clear_notices();
}
}
}
}
}
I can't even force to checkout so i'm stuck with this.. can somebody clear my mind?

You can update your minimum product add to cart functionality, and remove validation for your specific products like this:
add_filter( 'woocommerce_quantity_input_args', 'custom_woocommerce_quantity_changes', 10, 2 );
function custom_woocommerce_quantity_changes( $args, $product ) {
$product_id = $product->get_id();
$product_title = $product->get_title();
//echo "<pre>"; print_r($product_title); echo "</pre>";
if($product_id == 1002 || $product_title == 'BOX'){
$args['input_value'] = 1;
$args['min_value'] = 1;
$args['max_value'] = 30;
$args['step'] = 1;
}else{
$args['input_value'] = 3; // Start from this value (default = 1)
$args['max_value'] = 30; // Max quantity (default = -1)
$args['min_value'] = 3; // Min quantity (default = 0)
$args['step'] = 1; // Increment/decrement by this value (default = 1)
}
return $args;
}
print your specific product id or product name and use same name or id in your if condition :
if($product_id == 1002 || $product_title == 'BOX')
For rest of product set min, max and input product validation from "else" parts.
