Here is how to replace all instances of a string in WordPress, just add the following code to your theme’s functions.php file:

function replace_text($text) {
	$text = str_replace('look-for-this-string', 'replace-with-this-string', $text);
	$text = str_replace('look-for-that-string', 'replace-with-that-string', $text);
	return $text;
}
add_filter('the_content', 'replace_text');

Clear checkout woocommerce!

Clean the cart when going directly to the <checkout>, perfect when only the purchase of a single product is required by the user.

In functions.php

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