php – 如何在Woocommerce中的“选择一个选项”中更改按钮文本？

if ( ! function_exists( 'wc_dropdown_variation_attribute_options' ) ) {

    /**
     * Output a list of variation attributes for use in the cart forms.
     *
     * @param array $args
     * @since 2.4.0
     */
    function wc_dropdown_variation_attribute_options( $args = array() ) {
        $args = wp_parse_args( $args,array(
            'options'          => false,'attribute'        => false,'product'          => false,'selected'         => false,'name'             => '','id'               => '','class'            => '','show_option_none' => __( 'Choose an option','woocommerce' ),'show_option_color' => __( 'Choose a color','show_option_size' => __( 'Choose a size','woocommerce' )
        ) );

        $options   = $args['options'];
        $product   = $args['product'];
        $attribute = $args['attribute'];
        $name      = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute );
        $id        = $args['id'] ? $args['id'] : sanitize_title( $attribute );
        $class     = $args['class'];

        if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
            $attributes = $product->get_variation_attributes();
            $options    = $attributes[ $attribute ];
        }

        echo '<select id="' . esc_attr( $id ) . '" class="' . esc_attr( $class ) . '" name="' . esc_attr( $name ) . '" data-attribute_name="attribute_' . esc_attr( sanitize_title( $attribute ) ) . '">';

        if ( $args['show_option_none'] ) {
            echo '<option value="">' . esc_html( $args['show_option_none'] ) . '</option>';
        }
        if ( $args['$id_colors'] ) {
            echo '<option value="">' . esc_html( $args['show_option_color'] ) . '</option>';
        }
        if ( $args['$id_sizes'] ) {
            echo '<option value="">' . esc_html( $args['show_option_size'] ) . '</option>';
        }

        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( $product->id,$attribute,array( 'fields' => 'all' ) );

                foreach ( $terms as $term ) {
                    if ( in_array( $term->slug,$options ) ) {
                        echo '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $args['selected'] ),$term->slug,false ) . '>' . apply_filters( 'woocommerce_variation_option_name',$term->name ) . '</option>';
                    }
                }
            } 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 );
                    echo '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name',$option ) ) . '</option>';
                }
            }
        }

        echo '</select>';
    }
}

您可以看到我尝试将show_option_color和show_option_size添加到数组中的位置,然后为它们添加if语句,但它似乎不起作用.我不确定如何引用select元素的id并根据if语句是否是正确的select元素来编写if语句.

这是我试图定位的HTML.

<select id="sizes" class="" name="attribute_sizes" data-attribute_name="attribute_sizes">Want this to say Choose a size</select>

<select id="colors" class="" name="attribute_sizes" data-attribute_name="attribute_sizes">Want this to say Choose a color</select>

variable.php代码行27 – 38：

<?php foreach ( $attributes as $attribute_name => $options ) : ?>
                    <tr>
                        <td class="label"><label for="<?php echo sanitize_title( $attribute_name ); ?>"><?php echo wc_attribute_label( $attribute_name ); ?></label></td>
                        <td class="value">
                            <?php
                                $selected = isset( $_REQUEST[ 'attribute_' . sanitize_title( $attribute_name ) ] ) ? wc_clean( $_REQUEST[ 'attribute_' . sanitize_title( $attribute_name ) ] ) : $product->get_variation_default_attribute( $attribute_name );
                                wc_dropdown_variation_attribute_options( array( 'options' => $options,'attribute' => $attribute_name,'product' => $product,'selected' => $selected ) );
                                echo end( $attribute_keys ) === $attribute_name ? '<a class="reset_variations" href="#">' . __( 'Clear selection','woocommerce' ) . '</a>' : '';
                            ?>
                        </td>
                    </tr>
                <?php endforeach;?>
