You have a store front using woocommerce and you would like have your visiters to clear the cart then redirect to the Shop page or Plans page (for changing subscriptions).

You just need to add an action that will clear cart items in template redirect hook.

In the custom function, check the current page slug & then clear the cart as per our condition.

Use the hook below in your theme’s functions.php or in a custom plugin file.

add_action( 'template_redirect', 'woocommerce_clear_cart_url' );
function woocommerce_clear_cart_url() {
    global $post;
    $slug = $post->post_name;
    if($slug == 'sample-page') {
        global $woocommerce;
        $woocommerce->cart->empty_cart();
    }
}

or if you don’t want to use a hard coded the page slug, this is the way I like.

add_action( 'init', 'woocommerce_clear_cart_url' );
function woocommerce_clear_cart_url() {
    if ( isset( $_GET['clear-cart'] ) ) {
        global $woocommerce;
        $woocommerce->cart->empty_cart();
    }
}

You need to add an action that will clear cart items in template redirect hook.

In the custom function, check the current page slug & then clear the cart as per our condition.

Use the below code snippet in your theme’s functions.php or custom plugin file.

add_action( 'template_redirect', 'woocommerce_clear_cart_url' );
function woocommerce_clear_cart_url() {
    global $post;
    $slug = $post->post_name;
    if($slug == 'sample-page') {
        global $woocommerce;
        $woocommerce->cart->empty_cart();
    }
}

If you don’t like hard coding the page slug, there is also a better method.

add_action( 'init', 'woocommerce_clear_cart_url' );
function woocommerce_clear_cart_url() {
    if ( isset( $_GET['clear-cart'] ) ) {
        global $woocommerce;
        $woocommerce->cart->empty_cart();
    }
}

Add the above code in your theme’s functions.php file.

Then redirect to a page by adding ?clear-cart query string to the end of your URL & that will clear all cart items.

Example:

http://example.com?clear-cart

or

http://example.com/sample-page/?clear-cart

The use of plugins is a great and quick way of getting functions to your site without coding but that brings a lot of risks; like your website going down or even worse slow down a website now these problems can easily be avoided by just writing a line or two of code within your functions.php file.

Recently a new client of mine have a five different plugins to do the following.

add_action( 'woocommerce_after_add_to_cart_button', 'return_policy', 20 );

function return_policy() {
  echo '<p id="rtrn">Free shipping & returns. <a href="shipping-returns/">Learn more...</a></p>';
}

for the few that don’t i place id=”rtrn” in the html to show you how to take full CSS control.

so please look for other ways to provide service to your client or clients.

Quick is now never the way.
