Question

我正在Wordpress中构建一个网格，该网格具有将用作过滤器的自定义分类术语。我一直在使用'terms' => array()中的变量。一种类型的变量起作用，一种不起作用。

以下是查询：

$args = array(
    'posts_per_page' => -1,
    'post_type' => 'plant',
    'orderby' => 'name',
    'order' => 'ASC',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'trail_location',
            'field' => 'slug',
            'terms' => array($trailLocationList),  
        ),
        array(
            'taxonomy' => 'bloom_time',
            'field' => 'slug',
            'terms' => array($bloomTime),
        )
    )
);
$loop = new WP_Query( $args );

我可以将查询字符串值转换为var并且它可以工作：

$bloomTime = $_GET['bloom_time']; 
'terms' => array($bloomTime).

静态值有效：'terms' => array('loc1', 'loc2', 'loc3')。

什么不起作用是从现有分类标本的数组创建变量。

$terms = get_terms("trail_location");
$count = count($terms);
if ( $count > 0 ){
    foreach ( $terms as $term ) {
      $trailLocationList[] = $term->slug;
    }
}
$trailLocationList = implode("', '",$trailLocationList);
$trailLocationList = "'".$trailLocationList."'";

var在静态示例('loc1', 'loc2', 'loc3')中输出我需要的确切字符串，但由于某种原因查询不起作用。我测试过，两个变量都是字符串。

根据我的评论，其中带逗号的字符串不是数组。删除implode步骤并使用$ trailLocationList数组作为术语：

$terms = get_terms("trail_location");
$count = count($terms);
if ( $count > 0 ){
    foreach ( $terms as $term ) {
      $trailLocationList[] = $term->slug;
    }
}
/* why?? dont do this
$trailLocationList = implode("', '",$trailLocationList);
$trailLocationList = "'".$trailLocationList."'";
*/

$args = array(
    'posts_per_page' => -1,
    'post_type' => 'plant',
    'orderby' => 'name',
    'order' => 'ASC',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'trail_location',
            'field' => 'slug',
            //'terms' => array($trailLocationList),  wrong
            'terms' => $trailLocationList //correct
        ),
        array(
            'taxonomy' => 'bloom_time',
            'field' => 'slug',
            'terms' => array($bloomTime),
        )
    )
);
$loop = new WP_Query( $args );

Wordpress分类法查询，术语数组中的一个字符串变量不起作用
