Question

您好我正在尝试执行此查询，提取具有3个属性的物联网商品（Collezione，Finitura，Pietre）。但我们可以设置无，1,2或3个过滤器，所以我想问一下，如果没有设置过滤器，我必须设置哪个值。我认为-1但这不适用于此。

下面你可以找到我的代码。提前谢谢。

$args = array(
    'post_type' => 'product',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'tax_query'             => array(
        'relation' => 'AND',
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id',
            'terms'         => $cat_id,
            'operator'      => 'IN' 
        ),
        array(
            'taxonomy'      => 'pa_collezione',
            'field' => 'term_taxonomy_id', 
            'terms'         => $pa_collezione,
            'operator'      => 'IN' 
        ),
        array(
            'taxonomy'      => 'pa_finitura',
            'field' => 'term_taxonomy_id',
            'terms'         => $pa_finitura,
            'operator'      => 'IN'
        ),            
        array(
            'taxonomy'      => 'pa_pietre',
            'field' => 'term_taxonomy_id',
            'terms'         => $pa_pietre,
            'operator'      => 'IN'
        )
    )
);

$products = get_posts( $args );

Answer 1

我认为您的条款类似于＆＃39; pa_collezione＆＃39;是您的 product_cat 分类标准。

您的tax_query应该只有一个术语字段的术语数组。

    'tax_query' => array(
         array(
            'taxonomy' => 'product_cat',
           'field'    => 'term_id',
           'terms'    => $array_of_term_ids,  
       ),
    )

您在条款数组中执行过滤，而不是添加额外的关系。

Answer 2

如果未设置参数，我发现解决方案设置为'NOT IN'而不是'IN'。以下是解决方案。

$cat_id = $_POST['category'];
$pa_finitura= $_POST['finitura'];
$pa_collezione= $_POST['collection'];
$pa_pietre= $_POST['pietre'];

if($pa_collezione=="-1"){$cond_collezione='NOT IN';}else{$cond_collezione = 'IN';}
if($pa_finitura=="-1"){$cond_finitura='NOT IN';}else{$cond_finitura = 'IN';}
if($pa_pietre=="-1"){$cond_pietre='NOT IN';}else{$cond_pietre = 'IN';}

require_once('../../../../wp-load.php');
$args = array(
    'post_type' => 'product',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'tax_query'             => array(
        'relation' => 'AND',
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => $cat_id,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        ),
        array(
            'taxonomy'      => 'pa_collezione',
            'field' => 'term_taxonomy_id', //This is optional, as it defaults to 'term_id'
            'terms'         => $pa_collezione,
            'operator'      => $cond_collezione // Possible values are 'IN', 'NOT IN', 'AND'.
        ),

        array(
            'taxonomy'      => 'pa_finitura',
            'field' => 'term_taxonomy_id', //This is optional, as it defaults to 'term_id'
            'terms'         => $pa_finitura,
            'operator'      => $cond_finitura // Possible values are 'IN', 'NOT IN', 'AND'.
        ),


        array(
            'taxonomy'      => 'pa_pietre',
            'field' => 'term_taxonomy_id', //This is optional, as it defaults to 'term_id'
            'terms'         => $pa_pietre,
            'operator'      => $cond_pietre // Possible values are 'IN', 'NOT IN', 'AND'.
        )
    )
);
$products = get_posts( $args );
