我想在WooCommerce Products中为每个Store自定义帖子类型创建一个库存级别字段。我已经创建了商店自定义帖子类型，并向其中添加了3个商店。我想在每次有人添加商店时自动添加一个"商店库存级别"字段，以便我可以检查商店级别的库存。
我正试图将自定义字段放在"产品"->"库存"->"存货数量"下。
我试过这个：
$post_type = 'store';
$tax = 'show-topic';
$inv_arg_terms = get_terms(array('orderby' => 'id', 'order' => 'ASC'));
if ($inv_arg_terms) {
$args = array(
'post_type' => $post_type,
'post_status' => 'publish',
'posts_per_page' => - 1,
'orderby' => 'title',
'order' => 'ASC'
); // END $args
$my_query = null;
$my_query = new WP_Query($args);
if ($my_query->have_posts()) {
while ($my_query->have_posts()) : $my_query->the_post();
add_action( 'woocommerce_product_options_inventory_product_data', 'wc_inventory_stock_product_field' );
function wc_inventory_stock_product_field() {
woocommerce_wp_text_input( array( 'id' => 'stock_level_' . the_title(), 'class' => 'short wc_input_stock', 'label' => __( 'Stock Level at ' . the_title(), 'woocommerce' ) . ' (' . get_woocommerce_currency_symbol() . ')' ) );
}
add_action( 'save_post', 'wc_cost_save_product' );
function wc_cost_save_product( $product_id ) {
// stop the quick edit interferring as this will stop it saving properly, when a user uses quick edit feature
if (wp_verify_nonce($_POST['_inline_edit'], 'inlineeditnonce'))
return;
// If this is a auto save do nothing, we only save when update button is clicked
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return;
if ( isset( $_POST['stock_level_' . the_title()] ) ) {
if ( is_numeric( $_POST['stock_level_' . the_title()] ) )
update_post_meta( $product_id, 'stock_level_' . the_title(), $_POST['cost_price'] );
} else delete_post_meta( $product_id, 'stock_level_' . the_title() );
}
endwhile;
} // END if have_posts loop
wp_reset_query();
} // END if $inv_arg_terms
我得到了这个：
致命错误：调用中未定义的函数get_userdata（）…/wp包含/query.php，第4758行
我的想法可能吗？我该怎么做？
谢谢，感谢我能得到的一切帮助。
终于开始工作了。这是代码：
add_action( 'woocommerce_product_options_inventory_product_data', 'wc_stock_product_field' );
add_action( 'woocommerce_process_product_meta', 'wc_stock_save_product' );
function wc_stock_product_field() {
global $woocommerce, $post;
$post_type = 'store';
$args = array(
'post_type' => $post_type,
'post_status' => 'publish',
'posts_per_page' => - 1,
'orderby' => 'id',
'order' => 'ASC',
'caller_get_posts' => 1
); // END $args
$store_query = null;
$store_query = new WP_Query($args);
if ($store_query->have_posts()) {
while ($store_query->have_posts()) : $store_query->the_post();
woocommerce_wp_text_input(
array(
'id' => get_the_id() ,
'class' => 'short wc_input_stock',
'label' => __( 'Stock Level @ ' . get_the_title(), 'woocommerce' ) ) );
endwhile;
} // END if have_posts loop
wp_reset_query();
}
function wc_stock_save_product( $product_id ) {
// stop the quick edit interferring as this will stop it saving properly, when a user uses quick edit feature
if (wp_verify_nonce($_POST['_inline_edit'], 'inlineeditnonce'))
return;
// If this is a auto save do nothing, we only save when update button is clicked
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
return;
$post_type = 'store';
$args = array(
'post_type' => $post_type,
'post_status' => 'publish',
'posts_per_page' => - 1,
'orderby' => 'id',
'order' => 'ASC',
'caller_get_posts' => 1
); // END $args
$store_query = null;
$store_query = new WP_Query($args);
if ($store_query->have_posts()) {
while ($store_query->have_posts()) : $store_query->the_post();
if ( isset( $_POST[get_the_id()] ) ) {
if ( is_numeric( $_POST[get_the_id()] ) )
update_post_meta( $product_id, get_the_id(), $_POST[get_the_id()] );
} else delete_post_meta( $product_id, get_the_id() );
endwhile;
} // END if have_posts loop
wp_reset_query();
}
