WooCommerce：将 3 个自定义简码合二为一
WooCommerce: Merge 3 custom shortcodes in one
我有三个独立的 woocommerce 片段，每个片段都有一个功能。
我试图将它们组合在一个脚本中，但似乎 return 不能超过一个值。
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 > '$is_24h_ago'
" );
return '<span style="color:#fff;text-align:center;font-size:12px">New
Proposals: ' . reset($result);
}
add_shortcode( 'new_proposals', 'new_proposals2' );
我尝试组合所有脚本并将函数一个接一个地放置，并尝试 return 将这 3 个值放在 3 个函数的末尾。但只有第一个是 returned.
或 return 每个函数末尾的值，运气不好。
我的目标是拥有类似于：
Proposals: Taken(x) | New(x) | Left(x)
将 3 个短代码合并为一个非常简单，可以通过以下方式完成：
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' );
这应该有效
用法： [order_multi_count] 或 [order_multi_count status="processing"]
虽然接受的答案是完全有效的，但这里有一个更高效和可扩展的代码。
您的代码存在的问题是，对于每次页面加载，您都在获取和计算相同的不变数据。
这是一种开销，不会影响几千名访问者的网站，但当产品、订单或并发流量上升时，上述代码将开始成为瓶颈。
在这段代码中，我广泛使用了 Transient API（缓存），而不是在每个页面加载时更新计数，而是使用缓存的计数。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，一旦订购了产品（或取消了订单），代码就会更新 Taken 和 Left。
此代码已完全测试
