Wordpress. Woocommerce. Action hook BEFORE adding to cart - wordpress

What i need to do:
I want to run some checks on a product before being added to the cart.
More exactly:
I want to compare the product i am about to add to the cart, with the ones already added, to see if there are some conflicts.
An example:
Let's say we have a product named "Both shoes", and a product "left shoe".
A user adds "left shoe" to the cart. Then he adds "both shoes". I want to print an error instead of adding the "both shoes": Sorry, but you can't add both shoes if you've added left shoe to the cart. If you want to buy "both shoes", please first remove "left shoe".
I've looked at class-wc-cart.php and i found an action hook at line 811, but it's too late! It's after the product has been added
"do_action( 'woocommerce_add_to_cart', $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data );"
The add_to_cart method starts at line 705.

How can my "product conflict manager" function be hooked before line 801, without hacking woocommerce?
Thank you!

A bit late, but I think you are looking for add to cart validation, which is filterable. Here's an over simplified version:
function so_validate_add_cart_item( $passed, $product_id, $quantity, $variation_id = '', $variations= '' ) {
// do your validation, if not met switch $passed to false
if ( 1 != 2 ){
$passed = false;
wc_add_notice( __( 'You can not do that', 'textdomain' ), 'error' );
}
return $passed;
}
add_filter( 'woocommerce_add_to_cart_validation', 'so_validate_add_cart_item', 10, 5 );

if 'woocommerce_add_to_cart_validation' filter hook return false, there is redirection, how prevent redirection?

I use following filter hook to prevent add new product to cart if number of items in cart is 2. i.e. prevent add more than two items to cart.
add_filter( 'woocommerce_add_to_cart_validation', 'call_back_fn', 1, 3 );
function call_back_fn( $passed, $product_id, $quantity ) {
if( count(WC()->cart->get_cart()) >= 2 ){
wc_add_notice( __( "cart item limitation", "woocommerce" ), "error" );
$passed = false;
}
return $passed;
}
but when condition is true, when click 'add to cart' in shop page it redirects to that product single page and show notification. How prevent this and show notice in shop page?
Thanks

Change Verbiage on WooCommerce Subscriptions Customer Facing

I'm looking to change the verbiage for the word "Suspend" to the word "Pause" on the customer-facing side of WooCommerce Subscriptions. I have the filter that pulls up the action buttons but I'm unsure of how to pull the specific action of "Suspend" and change it to the word "Pause".
Here is the filter.
apply_filters( 'wcs_view_subscription_actions', $actions, $subscription );
Any help would be much appreciated. If you need more information I'm happy to provide what I can.
You can use the wcs_view_subscription_actions filter hook. this way. check below code. code will go in your active theme functions.php file.
add_filter( 'wcs_view_subscription_actions', 'change_action_buttons_label', 10, 2 );
function change_action_buttons_label( $actions, $subscription ){
if( isset( $actions['suspend'] ) ){
$actions['suspend']['name'] = __( 'Pause', 'woocommerce-subscriptions' );
}
return $actions;
}

Adding a hook to "Place order" button in woocommerce

When the user gets to the checkout, there is a button , the "Place order" button at the bottom of the form. I have been trying to add a hook to this button in woocommerce, but I don't seem to find the correct one, I have tried woocommerce_checkout_place_order... but it doesnt do anything.
function my_function() {
//write function
}
add_action( "woocommerce_order_status_pending", "my_function");
Thanks in advance!
You need this hook woocommerce_review_order_after_submit. It will execute any function you hook to it just after the submit area. with this hook you can add some html on the checkout page after the submit button.
But if you need to call a function after the user have pressed the "Place order" button - use woocommerce_checkout_order_processed. This one will hook you just after the order was created so you can use the freshly generated order details:
add_action( 'woocommerce_checkout_order_processed', 'is_express_delivery', 1, 1 );
function is_express_delivery( $order_id ){
$order = new WC_Order( $order_id );
//something else
}
You may check this site for some more hooks you might use on the checkout page.
## I USED THIS CODE FOR ADDING DELIVERY CHARGES DEPENDING UPON THE CART SUBTOTAL AND SOME POST FIELDS ##
function action_woocommerce_checkout_process($wccs_custom_checkout_field_pro_process )
{
global $woocommerce;
//Add Fuel Surcharge & CAF
function woo_add_cart_fee() {
global $woocommerce;
if ( WC()->cart->cart_contents_total < 1500 &&
$_POST['delivery_type']=='Pick Up') {
$fuel_surchargeandCAF = get_option( 'fuel_surchargeandCAF',
70 );
WC()->cart->add_fee( __('Delivery Charges', 'woocommerce'),
$fuel_surchargeandCAF, TRUE, '');
}
}
add_action( 'woocommerce_cart_calculate_fees', 'woo_add_cart_fee' );
};
add_action( 'woocommerce_checkout_process', 'action_woocommerce_checkout_process', 10,
1 );

Adding extra info to order

I am programmatically adding a product to the cart. Besides this, somehow, I want to store some extra info (an array) to the order. When the client finishes the order, I want to access that info through some WordPress actions. I'll have to do this immediately after adding the product to the cart, because the info may change after that, if the user doesn't finish the order right away. Is there any way I can do it, without putting the database to work?
You should probably use the WooCommerce Cart Item Meta API and the WooCommerce Order Item Meta API.
You use them like this:
// Add to cart item
// This is triggered on add to cart
add_filter('woocommerce_add_cart_item_data', 'my_add_cart_item_data', 10, 2);
function my_add_cart_item_data( $cart_item_meta, $product_id ) {
//Here we can easily filter what values should be added to what products using the $product_id
$cart_item_meta['my_meta_key'] = 'meta value';
return $cart_item_meta;
}
// Add to order item when the cart is converted to an order
// This is triggered when the order is created
add_action('woocommerce_add_order_item_meta', 'my_order_item_meta'), 10, 2);
function my_order_item_meta( $item_id, $values, $cart_item_key ) {
// The value stored in cart above is accessable in $values here
woocommerce_add_order_item_meta( $item_id, 'meta_key', $values['my_meta_key'] );
//Or add what ever you want
$meta_value = 'value';
woocommerce_add_order_item_meta( $item_id, 'meta_key', $meta_value );
}
I hope that helps.

Prevent WooCommerce brand from being sellable

Hi there we have an online store running on WooCommerce and using the WooCommerce brands plugin (http://docs.woothemes.com/document/wc-brands/) but there is one brand that we are allowed show online with price but not allowed to actually sell.
Is there a function I can add for this particular brand to functions.php that will change the add to cart button in category or widget layout to "more info" and link to the product and then on the product page instead of the add to cart section just have a text message saying to call the store.
You can filter WooCommerce's is_purchasable method. Any item that returns false will not be able to be purchased.
function so_26378581_purchasable( $purchasable, $product ){
if ( has_term( 'your-brand', 'product_brand', $product->id ) ){
$purchasable = false;
}
return $purchasable;
}
add_action( 'woocommerce_is_purchasable', 'so_26378581_purchasable', 10, 2 );
This uses conditional logic to test whether the $product in question has the your-brand term in the product_brand taxonomy... via the has_term() function.
By the way, this is not the type of functionality that belongs in functions.php. Your theme should only be concerned with display/appearances. I would recommend that you make this its own plugin, or add to to a site specific snippets plugin.
to me it made no error message, but it did not work, as applied in my test subject and stand continues with two products of different brands.
I put this code:
function so_26378581_purchasable( $purchasable, $product ){
if ( has_term( 'product_brand', 'product_brand', $product->id ) ){
$purchasable = false;
}
return $purchasable;
}
add_action( 'woocommerce_is_purchasable', 'so_26378581_purchasable', 10, 2 );
