[英]automatically create new post for each custom taxonomy term inserted by user
Alright, here's what I'm trying to achieve. 好吧,这就是我要实现的目标。 I have a custom post type called 'Campaigns' and a custom taxonomy called 'Countries' that has been assigned to the campaign post type. 我有一个名为“广告系列”的自定义帖子类型和一个已分配给广告系列帖子类型的自定义分类法“国家”。 When a user adds a new country (tags a new country to a campaign) I want to duplicate the current post, name the new post the name of the country just assigned, and make it a child of the current post. 当用户添加新国家(向广告系列添加新国家标签)时,我要复制当前帖子,将新帖子命名为刚分配的国家/地区名称,并将其作为当前帖子的子代。
Currently, I'm hooking into 'set_object_terms' and on the save of the terms determining what new terms have been created. 目前,我正在使用“ set_object_terms”,并保存确定新术语创建的术语。 I'm then trying to insert a new post for each of the terms, however I'm creating an infinite loop. 然后,我尝试为每个术语插入新的帖子,但是我正在创建一个无限循环。 I've tried creating a global to stop the loop, but I'm running into some issues. 我尝试创建一个全局循环来停止循环,但是遇到了一些问题。 This is what I have so far. 到目前为止,这就是我所拥有的。
$GLOBALS['control_campaign_count'] = 0;
add_action('set_object_terms','save_terms',10,6);
function save_terms($object_id, $terms, $tt_ids, $taxonomy, $append, $old_tt_ids) {
//Assuming we only want terms from specific taxonomy
//If not simply remove this conditional
$our_taxonomy = 'country';
if($taxonomy == $our_taxonomy){
//Added terms are specified terms, that did not already exist
$added_tt_ids = array_diff($tt_ids, $old_tt_ids);
if ($append) {
//If appending terms - nothing was removed
$removed_tt_ids = array();
} else {
//Removed terms will be old terms, that were not specified in $tt_ids
$removed_tt_ids = array_diff($old_tt_ids, $tt_ids);
}
/*,
Currently we have the taxonomy term IDs */
foreach($added_tt_ids as $term){
$added_terms[] = get_term_by( 'term_taxonomy_id',$term,$taxonomy);
$name = $added_terms->name;
echo $name;
// Add New Post
add_action('wp_insert_post', 'add_new_campaign');
function add_new_campaign() {
if($GLOBALS['control_campaign_count'] === 1) {
return;
}
$GLOBALS['control_campaign_count']++;
$new_post_arguments = array(
'post_title' => 'Japan',
'post_content' => '',
'post_status' => 'publish',
'post_type' => 'campaigns',
'post_parent' => 1156
);
$id = wp_insert_post($new_post_arguments);
update_post_meta($id, 'keywords');
}
}
foreach($removed_tt_ids as $term){
$removed_terms[] = get_term_by( 'term_taxonomy_id',$term,$taxonomy);
}
//$added_terms contains added term objects
//$removed_terms contains removed term objects
}
}
Ideas? 有想法吗? Thoughts on a better way to achieve this? 关于实现此目标的更好方法的想法? Thank you in advance. 先感谢您。
I'd use the same hook. 我会使用相同的钩子。 But.. 但..
Here's the code I used, which worked well for me: 这是我使用的代码,对我来说效果很好:
add_action( 'set_object_terms', 'auto_create_campaigns', 10, 6 );
function auto_create_campaigns( $object_id, $terms, $tt_ids, $taxonomy, $append, $old_tt_ids ) {
if ( 'campaigns' !== get_post_type( $object_id ) || 'country' !== $taxonomy ) {
return;
}
if ( $append ) {
$term_ids = $tt_ids;
} else {
$term_ids = array_diff( $tt_ids, $old_tt_ids );
}
$post = get_post( $object_id, ARRAY_A );
unset( $post['ID'] );
foreach ( $term_ids as $term_id ) {
// Remove the hook (to avoid infinite loop).
remove_action( 'set_object_terms', 'auto_create_campaigns', 10, 6 );
$term = get_term( $term_id, $taxonomy );
if ( is_wp_error( $term ) || empty( $term ) ) {
continue;
}
$post['post_title'] = $term->name;
$post['post_name'] = $term->slug;
$post['post_parent'] = $object_id;
$post_id = wp_insert_post( $post );
/*if ( $post_id ) {
// Copy the parent's "countries".
// wp_set_post_terms( $post_id, $terms, $taxonomy );
}*/
/*if ( $post_id ) {
// Copy the parent's custom fields.
// ..
}*/
// Add it back.
add_action( 'set_object_terms', 'auto_create_campaigns', 10, 6 );
}
}
That code only copies the standard post data such as post_title
; 该代码仅复制标准的post数据,例如post_title
; however, it is possible to also copy the parent post's "countries"/terms and/or custom fields. 但是,也可以复制父帖子的“国家/地区” /术语和/或自定义字段。
It's probably better to remove the hook and add it back (at the end of each iteration in the foreach
loop) than using the global $_in_auto_create_campaigns
. 与使用全局$_in_auto_create_campaigns
相比,最好删除钩子并将其添加回去 (在foreach
循环中每次迭代的末尾 )。
Hopefully that also helps you with the grandchild posts: 希望这对您的孙子职位也有帮助:
How can I set the terms, allow grandchild posts, and not get in an infinite loop? 如何设置条件,允许孙子发帖并且不陷入无限循环?
(You can also try this , which uses the same method, but the remove_action()
and add_action()
are placed near the wp_set_post_terms()
) (您也可以尝试使用相同的方法来尝试this ,但是remove_action()
和add_action()
放在wp_set_post_terms()
附近 )
