我有三个独立的woocommerce片段，每个片段都有一个功能。我试图在一个脚本中将它们组合在一起，但似乎无法返回多个值。
function display_woocommerce_order_count2( $atts, $content = null ) {
$args = shortcode_atts( array(
'status' => 'completed',
), $atts );
$statuses = array_map( 'trim', explode( ',', $args['status'] ) );
$order_count = 0;
foreach ( $statuses as $status ) {
// if we didn't get a wc- prefix, add one
if ( 0 !== strpos( $status, 'wc-' ) ) {
$status = 'wc-' . $status;
}
$order_count += wp_count_posts( 'shop_order' )->$status;
}
ob_start();
return '<span style="color:#fff;text-align:center;font-size:12px">Deals:' .
$order_count;
$user->total;
return ob_get_clean();
}
add_shortcode( 'wc_order_count3', 'display_woocommerce_order_count2' );
function get_instock_products_count(){
global $wpdb;
// The SQL query
$result = $wpdb->get_col( "
SELECT COUNT(p.ID)
FROM {$wpdb->prefix}posts as p
INNER JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
WHERE p.post_type LIKE '%product%'
AND p.post_status LIKE 'publish'
AND pm.meta_key LIKE '_stock_status'
AND pm.meta_value LIKE 'instock'
" );
return '<span style="color:#fff;text-align:center;font-size:12px">Proposals
Left: ' . reset($result);
}
add_shortcode('fp7', 'get_instock_products_count');
function new_proposals2(){
global $wpdb;
// 24 hours ago
$is_24h_ago = date("Y-m-d H:i:s", strtotime(date("Y-m-d H:i:s")." -1day"));
// The SQL query
$result = $wpdb->get_col( "
SELECT COUNT(p.ID)
FROM {$wpdb->prefix}posts as p
WHERE p.post_type LIKE '%product%'
AND p.post_status LIKE 'publish'
AND p.post_date > '$is_24h_ago'
" );
return '<span style="color:#fff;text-align:center;font-size:12px">New

}
add_shortcode( 'new_proposals', 'new_proposals2' );
我尝试组合所有脚本并将函数放在一起，并尝试在3个函数的末尾返回这3个值。但只返回第一个。
或者在每个函数结束时返回值，没有运气。
我的目标是有类似的东西：
建议：采取（x）|新（x）|左右（x）
要将3个短代码合并为一个非常简单，可以这样做：
function order_multi_count( $atts, $content = null ) {
global $wpdb;
$args = shortcode_atts( array(
'status' => 'completed',
), $atts );
## ---- ---- ---- ---- ---- ---- TAKEN ---- ---- ---- ---- ---- ---- ---- ##
$statuses = array_map( 'trim', explode( ',', $args['status'] ) );
$taken = 0;
foreach ( $statuses as $status ) {
// if we didn't get a wc- prefix, add one
if ( 0 !== strpos( $status, 'wc-' ) ) {
$status = 'wc-' . $status;
}
$taken += wp_count_posts( 'shop_order' )->$status;
}
## ---- ---- ---- ---- ---- ---- LEFT ---- ---- ---- ---- ---- ---- ---- ##
// The SQL query
$result = $wpdb->get_col( "
SELECT COUNT(p.ID)
FROM {$wpdb->prefix}posts as p
INNER JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
WHERE p.post_type LIKE '%product%'
AND p.post_status LIKE 'publish'
AND pm.meta_key LIKE '_stock_status'
AND pm.meta_value LIKE 'instock'
" );
$left = reset($result);
## ---- ---- ---- ---- ---- ---- NEW ---- ---- ---- ---- ---- ---- ---- ##
// 24 hours ago
$is_24h_ago = date("Y-m-d H:i:s", strtotime(date("Y-m-d H:i:s")." -1day"));
// The SQL query
$result2 = $wpdb->get_col( "
SELECT COUNT(p.ID)
FROM {$wpdb->prefix}posts as p
WHERE p.post_type LIKE '%product%'
AND p.post_status LIKE 'publish'
AND p.post_date > '$is_24h_ago'
" );
$new = reset($result2);
## ---- ---- ---- ---- ---- RETURNING VALUE ---- ---- ---- ---- ---- ---- ##
$style = 'style="color:#fff;text-align:center;font-size:12px"';
return "<span $style><strong>Proposals:</strong> Taken ($taken) | New ($new) | Left ($left)</span>";
}
add_shortcode( 'order_multi_count', 'order_multi_count' );
这应该工作
用法：[order_multi_count]或[order_multi_count status="processing"]
虽然接受的答案是完全有效的，但这里的代码更具性能和可扩展性。
您的代码的问题是，对于每个页面加载，您将获取和计算相同的非更改数据。
这是一个开销，不会影响几千名访客的网站，但当产品，订单或并发流量超过代码时，将开始成为瓶颈。
在这段代码中，我广泛使用了Transient API（缓存），而不是更新每个页面加载的计数，它将使用缓存计数。最好的部分是，当每个计数中使用的任何数据发生变化时，它会自动更新缓存的计数。
例如，只要订购产品（或订单取消），代码就会更新Taken和Left。
此代码已经过全面测试

您可以在CSS中使用.proposal-stats类来设置输出样式。
