将 Woo Commerce 下拉菜单转换为单选按钮

几年后，官方repo中有一个解决方案:http://wordpress.org/plugins/woocommerce-radio-buttons/p>

缺少的部分是插件 dequeue 的 WooCommerce add-to-cart-variation.js 脚本并加载自己的脚本，以便通过更改单选按钮输入来触发正确的事件.

I'm having trouble converting the variation dropdowns into radio buttons a woocommerce enabled site. I've tried the answer found here but I can't seem to make this solution work. I've also tried editing the code in the variable.php file.

So far the most success is the second approach, editing the variable.php code and changing the tags to tags. The problem is the natural jQuery event isn't triggered when the radio buttons are clicked.

If any of you know a simpler way to convert the dropdowns to radios, or simply make the jQuery event fire, it'd be much appreciated.

Relevant code I could get my hands on:

<?php $loop = 0; foreach ( $attributes as $name => $options ) : $loop++; ?>

<tr>

<td class="label"><label for="<?php echo sanitize_title($name); ?>"><?php echo $woocommerce->attribute_label($name); ?></label></td>

<td class="value"><select id="<?php echo esc_attr( sanitize_title($name) ); ?>" name="attribute_<?php echo sanitize_title($name); ?>">

<option value=""><?php echo __('Choose an option', 'woocommerce') ?>&hellip;</option>

<?php 

    if ( is_array( $options ) ) {

        if ( empty( $_POST ) )

            $selected_value = ( isset( $selected_attributes[ sanitize_title( $name ) ] ) ) ? $selected_attributes[ sanitize_title( $name ) ] : '';

        else

            $selected_value = isset( $_POST[ 'attribute_' . sanitize_title( $name ) ] ) ? $_POST[ 'attribute_' . sanitize_title( $name ) ] : '';

        // Get terms if this is a taxonomy - ordered

        if ( taxonomy_exists( sanitize_title( $name ) ) ) {

            $terms = get_terms( sanitize_title($name), array('menu_order' => 'ASC') );

            foreach ( $terms as $term ) {

                if ( ! in_array( $term->slug, $options ) ) continue;

                echo '<option value="' . $term->slug . '" ' . selected( $selected_value, $term->slug ) . '>' . apply_filters( 'woocommerce_variation_option_name', $term->name ) . '</option>';

            }

        } else {

            foreach ( $options as $option )

                echo '<option value="' . $option . '" ' . selected( $selected_value, $option ) . '>' . apply_filters( 'woocommerce_variation_option_name', $option ) . '</option>';

        }

    }

?>

Relevant Javascript. I change the 'select' elements ot 'input:radio' but it still doesn't work.

jQuery(document).ready(function($) {

A few years later and there is a solution in the official repo: http://wordpress.org/plugins/woocommerce-radio-buttons/

The missing piece is that the plugin dequeue's the WooCommerce add-to-cart-variation.js script and loads its own in order to trigger the right events via changes to the radio button inputs.
