[英]PHP Import WP Terms child term into custom post type
I have created a import tool to import data from a json file to create posts in my custom post type. 我创建了一个导入工具,用于从json文件导入数据,以自定义帖子类型创建帖子。 It all works well and I can import acf fields as well as assigned terms. 一切正常,我可以导入acf字段以及指定的条款。 My question is, how can I import child term assigned to the term. 我的问题是,如何导入分配给该术语的子术语。
I have two variables right now that collects the data. 我现在有两个变量来收集数据。 I would like the have the variable eventCategoryChildName to assign its vaule as a child term to eventCategoryID 我想让变量eventCategoryChildName将其有效值作为子项分配给eventCategoryID
$eventCategoryChildName = $ev['OfficialCity'];
$eventCategoryId = $ev['RegionID'];
Here is how the import of terms functions right now without child terms: 这是现在没有子术语的情况下术语导入的功能:
// set category terms
$cat_ids = $eventCategoryName;
// Add these categories, note the last argument is true.
wp_set_object_terms( $post_id, $cat_ids, 'lan', true );
Edit: 编辑:
So I managed to import the child associated to the right parents but they are not checked to the post 因此,我设法将与正确的父母相关联的孩子导入,但未将其选中
// set category terms
$cat_ids = $eventCategoryName;
// Import category name
$term_taxonomy_ids = wp_set_object_terms( $post_id, $cat_ids, 'lan', true );
$parent_term = wp_set_object_terms( $post_id, $cat_ids, 'lan', true );
// Check terms import for errors
if ( is_wp_error( $term_taxonomy_ids ) ) {
// There was an error somewhere and the terms couldn't be set.
echo $return->get_error_message();
} else {
// Success! These categories were added to the post.
}
$parent_term = term_exists( $eventCategoryName, 'lan' );
wp_insert_term(
$eventCategoryChildName, // Customize as you wish
'lan',
array(
'parent' => $parent_term['term_id'],
'slug' => $eventCategoryChildName // Customize as you wish
)
);
if ( !is_wp_error( $child_term_result ) ) {
wp_set_object_terms( $post_id, $child_term_result['term_id'], 'lan', true );
}
Firstly, you should check the result of wp_set_object_terms
, to see if an error was returned: 首先,您应该检查wp_set_object_terms
的结果,以查看是否返回了错误:
$term_taxonomy_ids = wp_set_object_terms( $post_id, $cat_ids, 'lan', true );
if ( is_wp_error( $term_taxonomy_ids ) ) {
// There was an error somewhere and the terms couldn't be set.
echo $return->get_error_message();
} else {
// Success! These categories were added to the post.
}
Then, the term you want to add may not exists. 然后,您要添加的术语可能不存在。 In such case, wp_set_object_terms
will return an invalid_taxonomy
error. 在这种情况下, wp_set_object_terms
将返回invalid_taxonomy
错误。 So you may want to add such missing term to your taxonomy: 因此,您可能需要在分类法中添加以下缺失术语:
wp_insert_term(
'Term Name', // Customize as you wish
'lan',
array(
'description' => 'Term desc', // Customize as you wish
'slug' => 'lan-slug1' // Customize as you wish
)
);
// For child term:
$parent_term = term_exists( 'parent_term_id', 'lan' );
$child_term_result = wp_insert_term(
'Child Term Name', // Customize as you wish
'lan',
array(
'parent' => $parent_term['term_id']
'description' => 'Term desc', // Customize as you wish
'slug' => 'lan-slug1' // Customize as you wish
)
);
// Add the child term to the post
if ( !is_wp_error( $child_term_result ) ) {
wp_set_object_terms( $post_id, $child_term_result['term_id'], 'lan', true );
}
Finally, be sure you execute this code after -at least- the init
hook of Wordpress. 最后,请确保至少在Wordpress的init
钩子之后执行此代码。 For instance: 例如:
function parse_my_json() {
// Your code here
}
add_action('init','parse_my_json');
