私は複数の著者のサイトを運営するつもりでした、私は他の著者の投稿を/wp-admin/edit.php
ページに表示したくありません。
私はこの問題を this thread のコードで解決しました。コードは次のとおりです。
function posts_for_current_author($query) {
global $pagenow;
if( 'edit.php' != $pagenow || !$query->is_admin )
return $query;
if( !current_user_can( 'manage_options' ) ) {
global $user_ID;
$query->set('author', $user_ID );
}
return $query;
}
add_filter('pre_get_posts', 'posts_for_current_author');
このコードはうまく機能します。他の作者からの投稿はここに表示されません。しかし、私は別の問題を見つけます - ページ上部のメニューは作者による関連投稿数を変えません、それは私のサイト内のすべての投稿の数を示しています。
私が言っているメニューはこんな感じです:
Mine () | All () | Published () | Draft () | Trash ()
()
内の番号を変更して作成者のみに関連付けられた番号を反映させるにはどうすればいいですか?
これが私が使っているものです:
// Show only posts and media related to logged in author
add_action('pre_get_posts', 'query_set_only_author' );
function query_set_only_author( $wp_query ) {
global $current_user;
if( is_admin() && !current_user_can('edit_others_posts') ) {
$wp_query->set( 'author', $current_user->ID );
add_filter('views_edit-post', 'fix_post_counts');
add_filter('views_upload', 'fix_media_counts');
}
}
// Fix post counts
function fix_post_counts($views) {
global $current_user, $wp_query;
unset($views['mine']);
$types = array(
array( 'status' => NULL ),
array( 'status' => 'publish' ),
array( 'status' => 'draft' ),
array( 'status' => 'pending' ),
array( 'status' => 'trash' )
);
foreach( $types as $type ) {
$query = array(
'author' => $current_user->ID,
'post_type' => 'post',
'post_status' => $type['status']
);
$result = new WP_Query($query);
if( $type['status'] == NULL ):
$class = ($wp_query->query_vars['post_status'] == NULL) ? ' class="current"' : '';
$views['all'] = sprintf(__('<a href="%s"'. $class .'>All <span class="count">(%d)</span></a>', 'all'),

Answer https://wordpress.stackexchange.com/a/49200/83038 に基づくより短い解決策。
注:WordPress 3.7.0以降で利用可能です。
function fix_count_orders( $counts, $type ) {
global $wpdb;
$query = "SELECT post_status, COUNT( * ) AS num_posts FROM {$wpdb->posts} WHERE post_type = %s";

$query .= ' GROUP BY post_status';
$results = (array) $wpdb->get_results( $wpdb->prepare( $query, $type ), ARRAY_A );
$counts = array_fill_keys( get_post_stati(), 0 );
foreach ( $results as $row ) {
$counts[ $row['post_status'] ] = $row['num_posts'];
}
return (object) $counts;
}
function query_set_only_author( $wp_query ) {

一番いい方法
これらのすべての回答にはセキュリティ上の懸念があります。
最善の方法は、カスタム機能を追加し、その機能によって投稿などを管理することです。
簡単な方法
WPは投稿編集画面だけでなく、Dashboardウィジェット、Ajaxレスポンスなどでも投稿数を参照しないため、Artemの解決策がより良いようです.
Artemのものに基づくより良い解決策のために。
wp_count_posts
がキャッシュされた投稿数を早く返します。$perm
フックの3番目のwp_count_posts
パラメータを尊重します。 readable
パーマに基づくユーザー自身の非公開投稿を含めるべきです。WP_Posts_List_Table
で数えられます。read_others_posts
機能が変更される可能性があります。追加の調整が必要な場合があります
post_author
query varをWP_Comment_Query
に設定することによって、他の投稿のコメントをフィルタリングします。wp_count_comments
フックによってコメント数を調整します。以下はWP 4.8のwp_post_counts()
に基づく修正版です。
