【问题描述】:
我正在尝试从 wc_cart_functions.php 文件中的 woocommerce 按钮中删除一个类。 wc_add_to_cart_message 函数中有一个字符串插入此字符串:
<a href="%s" class="button wc-forward">%s</a> %s
function wc_add_to_cart_message( $products, $show_qty = false ) {
$titles = array();
$count = 0;
if ( ! is_array( $products ) ) {
$products = array( $products );
$show_qty = false;
}
if ( ! $show_qty ) {
$products = array_fill_keys( array_keys( $products ), 1 );
}
foreach ( $products as $product_id => $qty ) {
$titles[] = ( $qty > 1 ? absint( $qty ) . ' × ' : '' ) . sprintf( _x( '“%s”', 'Item name in quotes', 'woocommerce' ), strip_tags( get_the_title( $product_id ) ) );
$count += $qty;
}
$titles = array_filter( $titles );
$added_text = sprintf( _n( '%s has been added to your cart.', '%s have been added to your cart.', $count, 'woocommerce' ), wc_format_list_of_items( $titles ) );
// Output success messages
if ( 'yes' === get_option( 'woocommerce_cart_redirect_after_add' ) ) {
$return_to = apply_filters( 'woocommerce_continue_shopping_redirect', wc_get_raw_referer() ? wp_validate_redirect( wc_get_raw_referer(), false ) : wc_get_page_permalink( 'shop' ) );
$message = sprintf( '<a href="%s" class="button wc-forward">%s</a> %s', esc_url( $return_to ), esc_html__( 'Continue Shopping', 'woocommerce' ), esc_html( $added_text ) );
} else {
$message = sprintf( '<a href="%s" class="button wc-forward">%s</a> %s', esc_url( wc_get_page_permalink( 'cart' ) ), esc_html__( 'View Cart', 'woocommerce' ), esc_html( $added_text ) );
}
wc_add_notice( apply_filters( 'wc_add_to_cart_message', $message, $product_id ) );
}
我试图创建一个过滤器来替换该特定字符串,因为它出现了两次,并且在这两种情况下我都希望删除该类。但这似乎不起作用:
add_filter( 'wc_add_to_cart_message', 'add_to_cart_mod');
function add_to_cart_mod($message) {
$message = str_replace ( '<a href="%s" class="button wc-forward">%s</a> %s' , '<a href="%s" class="button">%s</a> %s', $message );
return $message;
}
按原样设置此过滤器后,我仍然可以看到具有相同未更改类的按钮。有什么想法吗?
