使列在Woocommerce的管理产品列表面板中可排序 [英] Make columns sortable in admin products list panel in Woocommerce
问题描述
我在报价中添加了最高价的列.然后，我想对其进行排序.我已经准备好了:
I added the column with the highest value of the offer. And then I would like to make it sortable. I've prepared this:
//asl这将在产品列表中添加额外的列
// asl this will add extra column in the product list
add_filter( 'manage_edit-product_columns', array($this,'show_product_offers_amounts'),15 );
add_action( 'manage_product_posts_custom_column', array($this,'show_product_offers_amount_max'), 10, 2 );
//asl显示列
function show_product_offers_amounts($columns){
$columns['orig_offer_amount'] = 'Amount';
return $columns;
}
//asl将数据添加到列
// asl add the datas to column
function show_product_offers_amount_max( $column, $postid ) {
global $wpdb;
if ( $column == 'orig_offer_amount' ) {
$offers_max = $wpdb->get_var( " select max(meta_value)
from ".$wpdb->postmeta."
where meta_key='orig_offer_amount'
and meta_value!=''
and post_id in(
select p.post_id
from ".$wpdb->postmeta." as p
where p.meta_key='orig_offer_product_id' and
p.meta_value=".$postid.")"
);
if($offers_max > 0){
echo '<mark style="color: #3973aa;font-size: 13px;font-weight: 500;background: 0 0;line-height: 1;">'.$offers_max.'</mark>';
}
else{
echo '<span class="na">–</span>';
}
}
}
//asl将列注册为可排序
// asl register the column as sortable
function price_column_register_sortable( $columns ) {
$columns['orig_offer_amount'] = 'orig_offer_amount';
return $columns;
}
add_filter( 'manage_edit-product_sortable_columns', 'price_column_register_sortable' );
function price_column_orderby( $vars ) {
if ( isset( $vars['orderby'] ) && 'price' == $vars['orderby'] ) {
$offers_max = $wpdb->get_var( " select max(meta_value)
from ".$wpdb->postmeta."
where meta_key='orig_offer_amount'
and meta_value!=''
and post_id in(
select p.post_id
from ".$wpdb->postmeta." as p
where p.meta_key='orig_offer_product_id' and
p.meta_value=".$postid.")"
);
if($offers_max > 0){
$offers_max = $offers_max;
}
else{
$offers_max = 0;;
}
$vars = array_merge( $vars, array(
'meta_key' => 'orig_offer_amount',
'orderby' => $offers_max
) );
}
return $vars;
}
add_filter( 'request', 'price_column_orderby' );
此代码使wordpress将该列识别为可排序的.但这排序不正确.
This code makes that wordpress recognize the column as sortable. But it doesn't sort properly.
有什么主意吗?
根据LoicTheAztec的建议，我准备了以下内容:
Using LoicTheAztec suggestion I prepared something like this:
add_action( 'save_post', 'new_postmeta_to_products' );
function new_postmeta_to_products($post_id){
$post_type = get_post_type($post_id);
if($post_type == 'products') {
global $wpdb;
$maxId = $wpdb->get_var( " select post_id
from ".$wpdb->postmeta."
where meta_key='orig_offer_amount'
and meta_value!=''
and post_id in(
select p.post_id
from ".$wpdb->postmeta." as p
where p.meta_key='orig_offer_product_id' and
p.meta_value=".$post_id.")
order by meta_value desc limit 1"
);
add_post_meta($post_id,'offer_max_id',$maxId);
}
}
但是它不起作用:(也许是因为$ post_id
But it doesn't work :( maybe because $post_id
推荐答案
感谢LoicTheAztec的提示，我已经准备了一些代码段.首先，我创建了产品时添加了新的postmeta:
Thanks to LoicTheAztec's hints I've prepared some snippet. First I've added new postmeta for product, when is created:
add_post_meta($post_id, 'offers_max_id', null);
add_post_meta($post_id, 'offers_max_value', null);
add_post_meta($post_id, 'offers_count', null);
然后，在功能new_offer_form_submit()中的www/wp-content/plugins/offers-for-woocommerce/public/class-offers-for-woocommerce.php中创建要约时，需要几行设置新的postmeta:
Then, a few lines to set the new postmeta when an offer is created in www/wp-content/plugins/offers-for-woocommerce/public/class-offers-for-woocommerce.php in function new_offer_form_submit() :
global $post;
$_product = get_post_meta($parent_post_id, 'offer_product_id', true);
global $wpdb;
$offerMax = $wpdb->get_results( " select post_id, meta_value
from ".$wpdb->postmeta."
where meta_key='orig_offer_amount'
and meta_value!=''
and post_id in(
select p.post_id
from ".$wpdb->postmeta." as p
where p.meta_key='orig_offer_product_id' and
p.meta_value=".$_product.")
order by meta_value desc limit 1"
,ARRAY_N);
update_post_meta($_product, 'offers_max_id', $offerMax[0][0]);
update_post_meta($_product, 'offers_max_value', $offerMax[0][1]);
$offerCount = $wpdb->get_var( "select count(post_id)
from ".$wpdb->postmeta."
where meta_key='orig_offer_product_id' and
meta_value=".$_product
);
update_post_meta($_product, 'offers_count', $offerCount);
然后，我们必须在function.php中为产品的管理面板添加新列:
Then, we must add new columns for products' admin panel in function.php:
// asl show the column
function my_cpt_columns( $columns ) {
$columns["offermaxid"] = "OfferId";
$columns["offercount"] = "Offers";
$columns["offermaxvalue"] = "Amount";
$columns["dateofend"] = "EndTime";
return $columns;
}
add_filter('manage_edit-product_columns', 'my_cpt_columns');
// asl take a data to the column
function my_cpt_column( $colname, $cptid ) {
if ( $colname == 'offermaxid')
echo get_post_meta( $cptid, 'offers_max_id', true );
if ( $colname == 'offercount')
echo get_post_meta( $cptid, 'offers_count', true );
if ( $colname == 'offermaxvalue')
echo get_post_meta( $cptid, 'offers_max_value', true );
if ( $colname == 'dateofend')
echo date("j M y H:i:s", (get_post_meta( $cptid, '_sale_price_dates_to', true )+60*60) );
if ( $colname == 'offerlefttime') {
$atime = time();
$d = (get_post_meta( $cptid, '_sale_price_dates_to', true ) - $atime)/(60*60*24);
$h = ( get_post_meta( $cptid, '_sale_price_dates_to', true ) - $atime - ( (60*60*24) * explode(".", $d)[0] ) )/(60*60);
$m = ( get_post_meta( $cptid, '_sale_price_dates_to', true ) - $atime - ( (60*60*24) * explode(".", $d)[0] ) - ( (60*60) * explode(".", $h)[0] ) )/(60);
echo floor($d) . "d " . floor($h) . "h " . floor($m) . "m";
}
}
add_action('manage_product_posts_custom_column', 'my_cpt_column', 10, 2);
// asl sortowanie
add_filter('manage_edit-product_sortable_columns', 'my_cpt_columns');
function my_sort_metabox( $vars ) {
if( array_key_exists('orderby', $vars )) {
if('OfferId' == $vars['orderby']) {
$vars['orderby'] = 'meta_value';
$vars['meta_key'] = 'offers_max_id';
}
if('Offers' == $vars['orderby']) {
$vars['orderby'] = 'meta_value';
$vars['meta_key'] = 'offers_count';
}
if('Amount' == $vars['orderby']) {
$vars['orderby'] = 'meta_value';
$vars['meta_key'] = 'offers_max_value';
}
if('EndTime' == $vars['orderby']) {
$vars['order'] = 'ASC';
$vars['orderby'] = 'meta_value';
$vars['meta_key'] = '_sale_price_dates_to';
}
}
return $vars;
}
add_filter('request', 'my_sort_metabox');
// asl dodanie kolumny wynikowej z czasem do końca
function my_cpt_column_time( $columns ) {
$columns["offerlefttime"] = "LeftTime";
return $columns;
}
add_filter('manage_edit-product_columns', 'my_cpt_column_time');
一切都很好，但是只有一件事是行不通的.我想按"EndTime" ASC列对产品进行排序. 有什么建议吗?
And everything nice but one thing doesn't work. I want to have the products sort by column 'EndTime' ASC. Any suggestions?
