如何在WooCommerce中更改”添加到购物车”（） _WordPress主题

我想使用< ul> < li> 代替< select> < option>
我在function.php中输入此代码, 但不起作用：

function wc_dropdown_variation_attribute_options( $args = array() ) { . . . $html= '< div class="tt-wrapper"> < div class="tt-title-options"> ??????:< /div> < ul id="' . esc_attr( $id ) . '" class="tt-options-swatch options-large ' . esc_attr( $class ) . '" name="' . esc_attr( $name ) . '" data-attribute_name="attribute_' . esc_attr( sanitize_title( $attribute ) ) . '" data-show_option_none="' . ( $show_option_none ? 'yes' : 'no' ) . '"> '; if ( ! empty( $options ) ) { if ( $product & & taxonomy_exists( $attribute ) ) { // Get terms if this is a taxonomy - ordered. We need the names too. $terms = wc_get_product_terms( $product-> get_id(), $attribute, array( 'fields' => 'all', ) ); foreach ( $terms as $term ) { if ( in_array( $term-> slug, $options, true ) ) { $html .= '< li> < a href="http://www.srcmini.com/#" value="' . esc_attr( $term-> slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term-> slug, false ) . '> ' . esc_html( apply_filters( 'woocommerce_variation_option_name', $term-> name, $term, $attribute, $product ) ) . '< /a> < /li> '; } } } else { foreach ( $options as $option ) { // This handles < 2.4.0 bw compatibility where text attributes were not sanitized. $selected = sanitize_title( $args['selected'] ) === $args['selected'] ? selected( $args['selected'], sanitize_title( $option ), false ) : selected( $args['selected'], $option, false ); $html.= '< li> < a href="http://www.srcmini.com/#" value="' . esc_attr( $option ) . '" ' . $selected . '> ' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option, null, $attribute, $product ) ) . '< /a> < /li> '; } } }$html .= '< /ul> < /div> < /div> '; echo apply_filters( 'woocommerce_dropdown_variation_attribute_options_html', $html, $args ); // WPCS: XSS ok. }
