notice

I am trying to alter messages displayed when adding an a product to cart and/ or updating the cart by hooking in to the woocommerce_add_message . It's not showing anything at all and I'm wondering why. I've tried echo and I've tried return__( Here's the code: add_filter('woocommerce_add_message', 'change_cart_message', 10); function change_cart_message() { $ncst = WC()->cart->subtotal; if ( is_checkout() ) { echo 'Your new order subtotal is: '.$ncst.'. <a style="color: green;" href="#customer_details">Ready to checkout?</a>'; } elseif ( is_product() ) { echo 'Your new order subtotal is: '.

Is there a way to hide/remove the notice "Product removed. Undo?" on the cart page, when the customer removed the item from the cart? I tried: add_filter( 'woocommerce_cart_item_removed_title', '__return_null' ); but this only hides the title of the product, that has been removed... I couldn't find the right hook of the rest of the line ("removed" and "Undo?") To unset " {item_name} removed. Undo? " notice on cart page, you can trick Woocommerce with the following: add_action( 'template_redirect', 'null_removed_cart_item_message' ); function null_removed_cart_item_message() { // Only on cart

I understand that it is a best practice to have all variables defined and to check for array indexes before evaluating. However, I'm trying to run some tests on new functionalities developed on top of some legacy code which has not been coded this way. Behat fails with this message: Scenario: Add a new resource # features/accounting.feature:6 Given I am user "admin" # FeatureContext::iAmUser() Notice: Undefined index: 13 in classloader.php line 126 When I create a new resource # FeatureContext::iCreateANewResource() Then [...] I will fix these notices eventually, but I need Behat to ignore

I've suppressed notices for quite some time with no problems whatsoever but I am beginning to wonder if I'm doing the right thing. I can't seem to find any logical reason why I shouldn't just suppress them but some other people seem to think that suppressing them using error_reporting is a horrible thing to do, but why? The closest thing to an answer I could find was in this question but that's still far from the answer I'm looking for. Is there some sort of unforeseen downside to hiding all the notices that PHP generates? For example, to include a variable from a POST call back into the form
