Wp_query ordering problem

使用此选项时，我尝试按自定义字段值对结果排序：

// Search product distance
foreach( $productArrayShop as $id ) {
    $pdistance = $product_obj[\'current_distance\']=get_post_meta($id,\'current_distance\');
    echo \' Distance = \'.$pdistance[0].\', \';
    $arrayDistance[] = $pdistance[0];
}
//echo \'<b> Founded \'.count($arrayDistance).\' distance</b> \';

// Orderby distance
foreach ($arrayDistance as $d)
{
    $productd = array
    (
        \'post_type\' => \'product\',
        \'posts_per_page\'=> -1,
        \'order\' => \'ASC\',
        \'orderby\' => \'meta_value\',
        \'meta_key\' => \'current_distance\',
        \'fields\' => \'ids\',
        \'meta_query\' => array
        (
            array(
                \'key\' => \'current_distance\',
                \'value\' => $d,
                \'type\' => \'NUMERIC\',
                \'compare\'=> \'<\'
            )
        )
    );
    //Get product id
    $product_post = get_posts($productd);
    //echo $product_post[0].\', \';
    //echo count($product_post);
    $a[] = $product_post[0];
}
//echo \' Founded \'.count($a).\' ID\';

$resultD = implode(",", $a);
echo \' ID of product \'.$resultD.\', \';

结果是：距离=62.717，距离=726.727，产品ID是，8132281322，并且只有第一个产品出现在屏幕上，这是有意义的，因为相同的ID。。。我不明白为什么。

的转储

$a[]:  array(3) { ["map"]=> string(3) "yes" [0]=> int(81322) [1]=> int(81322) }

为什么我有两个相同的ID 8132281322？

如果我不使用查询排序，我的两个产品会显示在屏幕上（当然没有排序）。

跟踪时：

foreach ( $productArrayShop as $id ) {
    $pdistance = $product_obj[\'current_distance\']=get_post_meta($id,\'current_distance\');
    echo \' Distance = \'.$pdistance[0].\', \';
    $arrayDistance[] = $pdistance[0];
}

我的两个产品有两个距离。

工作代码为：

$productd = array(
    \'post_type\' => \'product\',
    \'posts_per_page\'=> -1,
    \'order\' => \'ASC\',
    \'orderby\' => \'meta_value\',
    \'meta_key\' => \'current_distance\',
    \'post__in\' => $productArrayShop // Here we get all the posts by the IDs with the right order.
);

$product_post = get_posts($productd);
foreach($product_post as $p) {
    $arrp[] = $p->ID;
}
$result = implode(",", $arrp);
echo \' ID of product \'.$result.\', \';

// View list of product based on road distance of user position
echo do_shortcode(\'[products ids="\' . $result . \'" per_page="8" columns="4" pagination="true" orderby="meta_value" order="ASC"]\');

感谢@Shibi对我的帮助！

/* So we don\'t need this. */ /* foreach ( $productArrayShop as $id ) { $pdistance = $product_obj[\'current_distance\']=get_post_meta($id,\'current_distance\'); echo \' Distance = \'.$pdistance[0].\', \'; $arrayDistance[] = $pdistance[0]; } */ /** * We dont need to loop for each distance we have already array for all the products IDs its all we need. */ $productd = array ( \'post_type\' => \'product\', \'posts_per_page\'=> -1, \'order\' => \'ASC\', \'orderby\' => \'meta_value\', \'meta_key\' => \'current_distance\', \'post__in\' => $productArrayShop // Here we get all the posts by the IDs with the right order. ); $product_post = get_posts($productd); // Then do something with the products... print_r($product_post); /** * You can loop to get each post object */ foreach($product_post as $p) { echo $p->ID; }

add_filter(\'woocommerce_shortcode_products_query\', \'woo_products_sc_distance_order\', 10, 3); function woo_products_sc_distance_order($args, $atts, $type) { if ($atts[\'orderby\'] == "distance") { $args[\'orderby\'] = \'meta_value\'; $args[\'meta_key\'] = \'current_distance\'; } return $args; }

使用新的WP-Query()从循环中过滤后期格式；

嗨，我目前正在为我的博客构建一个主题。下面的代码指向最新的帖子（特色帖子）。因为这将有一个不同的风格比所有其他职位。然而我想过滤掉帖子格式：链接使用我在循环中定义的WP查询，因为它给我带来了更多的灵活性。我该怎么做呢？ <?php $featured = new WP_Query(); $featured->query(\'showposts=1\'); ?> <?php while ($featured->have_post
