在WooCommerce中,我希望在变体下拉菜单中添加其他信息。我很难找到如何做到这一点。
基本上,我现在所拥有的是:
<select id="pa_size" class="" name="attribute_pa_size" data-attribute_name="attribute_pa_size" data-show_option_none="yes">
<option value="">Choose an option</option>
<option value="17-x-22" selected='selected'>17 x 22</option>
<option value="32-x-40" >32 x 40</option>
</select>`
我希望有这个:
<select id="pa_size" class="" name="attribute_pa_size" data-attribute_name="attribute_pa_size" data-show_option_none="yes">
<option value="">Choose an option</option>
<option value="17-x-22" selected='selected'>17 x 22 - 3 in stock</option>
<option value="32-x-40" >32 x 40 - 5 in stock</option>
</select>
在文件wc-template-fonction.php中,我找到了所有下拉菜单都构成的功能,这里是代码
function wc_dropdown_variation_attribute_options( $args = array() ) {
$args = wp_parse_args( apply_filters( 'woocommerce_dropdown_variation_attribute_options_args', $args ), array(
'options' => false,
'attribute' => false,
'product' => false,
'selected' => false,
'name' => '',
'id' => '',
'class' => '',
'show_option_none' => __( 'Choose an option', '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'];
$show_option_none = $args['show_option_none'] ? true : false;
$show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' ); // We'll do our best to hide the placeholder, but we'll need to show something when resetting options.
if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
$attributes = $product->get_variation_attributes();
$options = $attributes[ $attribute ];
}
$html = '<select id="' . esc_attr( $id ) . '" class="' . 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' ) . '">';
$html .= '<option value="">' . esc_html( $show_option_none_text ) . '</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->get_id(), $attribute, array( 'fields' => 'all' ) );
foreach ( $terms as $term ) {
if ( in_array( $term->slug, $options ) ) {
$html .= '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $args['selected'] ), $term->slug, false ) . '>' . esc_html( 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 );
$html .= '<option value="' . esc_attr( $option ) . '" ' . $selected . '>' . esc_html( apply_filters( 'woocommerce_variation_option_name', $option ) ) . '</option>';
}
}
}
$html .= '</select>';
echo apply_filters( 'woocommerce_dropdown_variation_attribute_options_html', $html, $args );
}
我是否可以使用过滤器或动作来实现我想要做的事情。我不认为编辑文件wc-template-function.php是最干净的方法,因为下次我做更新时它会被删除。
@LoicTheAztec确实为我提供了一种方法,但我不知道在哪里放置代码,这似乎不是正确的方法。我发现其他帖子解释了改变&#34;选择一个选项&#34;在下拉菜单中,他们主要使用add_filter()或add_action()函数与自定义函数here。但我不确定如何实现我想要的东西。你能帮助我吗?
我确定我不是唯一一个在WooCommerce上需要这种功能的人。我会继续寻找答案,如果我找到它,我会在这里发布解决方案!

最后我找到了答案!这是怎么做的: 在function.php文件中,我添加了整个wc_dropdown_variation_attribute_options()(上面的代码),然后在if(!empty($ options))中添加一个循环。这里是整个代码:
function wc_dropdown_variation_attribute_options( $args = array() ) {
global $product;
$variations = $product->get_available_variations();
$args = wp_parse_args( apply_filters( 'woocommerce_dropdown_variation_attribute_options_args', $args ), array(
'options' => false,
'attribute' => false,
'product' => false,
'selected' => false,
'name' => '',
'id' => '',
'class' => '',
'show_option_none' => __( 'Choose an option', '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 ];
}
$html = '<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'] ) {
$html .= '<option value="">' . esc_html( $args['show_option_none'] ) . '</option>';
}
if ( ! empty( $options ) ) {
//the loop is right here
foreach ( $options as $option ) {
foreach ($variations as $variation) {
if($variation['attributes'][$name] == $option) {
$stock = esc_html($variation['max_qty']);
//$edition = get_post_meta( get_the_ID(), 'edition', true)
}
}
$stock_text = ' - Edition of '.$stock;
// 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 .= '<option value="' . esc_attr( $option ) . '" ' . $selected . ' class="'.$class.'" '.$disabled.'>' . $option . $stock_text .'</option>';
//}
}
}
$html .= '</select>';
echo apply_filters( 'woocommerce_dropdown_variation_attribute_options_html', $html, $args );
}
感谢您的帮助!
