我在wordpress中有两个自定义分类法，它们附带了帖子，如下例所示：
Taxanomy A
Taxanomy B
1号岗位
2号岗位
根据需要，每个帖子都附带了两个分类法。我需要输出每个分类法A都有分类法B，每个分类法B都有X个帖子。
我想在数组中实现这一点，最终以JSON格式输出，这就是我设法编写和使用的内容，但结果不正确：
$TaxanomiesA = get_terms("TaxanomyA", array(\'hide_empty\' => false));
$TaxanomiesB = get_terms("TaxanomyB", array(\'hide_empty\' => false));
$TaxanomyAArray = array();
$TaxanomyBArray = array();
$postssArray = array();
foreach($TaxanomiesA as $TaxanomyA) {
$TaxanomyAArray[] = array (
\'id\' => $TaxanomyA->term_id,
\'name\' => $TaxanomyA->name,
\'TaxanomyB\' => $TaxanomyBArray
);
$args = array(//Arguments);
$posts = get_posts( $args );
foreach($TaxanomiesB as $TaxanomyB){
$TaxanomyBArray[] = array (
\'id\' => $TaxanomyB->term_id,
\'name\' => $TaxanomyB->name,
\'posts\' => $postssArray
);
foreach($posts as $post){
$postssArray[] = array (
\'id\' => $post->ID,
\'name\' => $post->title
);
}
}
}
$jsonOutput=array(
\'JSON\' => $TaxanomyAArray
);
echo json_encode($jsonOutput, JSON_UNESCAPED_SLASHES);
}
这是我想要实现的输出：
{
"JSON":[
{
"id":"1",
"name":"TaxonomyA Name",
"Taxonomy":[
{
"id":"1",
"name":"TaxonomyB Name",
"posts":[
{
"id":"1",
"name":"Post Title"
},
{
"id":"2",
"name":"Post Title 2"
}
]
}
]
}
]
}

问题是get_posts 正在外部调用函数$TaxanomiesB 环把它移到里面，确保电流$TaxanomyB 正在中的$args中使用get_posts.
将数据添加到$TaxanomyAArray 和$TaxanomyBArray 在每个for-each循环的末尾，否则数组中的第一个对象将为空。
您还需要重新初始化$array 变量位于每个父循环的开头，否则最终会在每个集合中多次重复每个帖子/分类法（如\'a\' => (1 => (foo, bar), 2 => (foo, bar, foo, bar)), \'b\' => 1 => (foo, bar, foo, bar, foo, bar) ...等等）。
$TaxanomiesA = get_terms("TaxanomyA", array(\'hide_empty\' => false));
$TaxanomiesB = get_terms("TaxanomyB", array(\'hide_empty\' => false));
$TaxanomyAArray = array();
foreach($TaxanomiesA as $TaxanomyA) {
$TaxanomyBArray = array();
foreach($TaxanomiesB as $TaxanomyB){
$args = array(//Arguments with $TaxonomyB);
$posts = get_posts( $args );
$postsArray = array();
foreach($posts as $post){
$postsArray[] = array (
\'id\' => $post->ID,
\'name\' => $post->title
);
}
$TaxanomyBArray[] = array (
\'id\' => $TaxanomyB->term_id,
\'name\' => $TaxanomyB->name,
\'posts\' => $postsArray
);
}
$TaxanomyAArray[] = array (
\'id\' => $TaxanomyA->term_id,
\'name\' => $TaxanomyA->name,
\'TaxanomyB\' => $TaxanomyBArray
);
}
$jsonOutput = array(
\'JSON\' => $TaxanomyAArray
);
echo json_encode($jsonOutput, JSON_UNESCAPED_SLASHES);
