Sembunyikan pos pengguna lain di panel admin

Saya bermaksud menjalankan situs multi-penulis, saya tidak ingin posting dari penulis lain ditampilkan di /wp-admin/edit.phphalaman.

Saya berhasil memecahkan masalah ini dengan kode dari utas ini . Kodenya seperti ini:

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');

Kode berfungsi dengan baik, menyembunyikan posting dari penulis lain untuk ditampilkan di sini. Tapi saya menemukan masalah lain - menu di atas halaman tidak mengubah jumlah posting terkait oleh penulis, itu menunjukkan jumlah semua posting di situs saya.

Menu yang saya maksud adalah seperti ini:

Mine () | All () | Published () | Draft () | Trash ()

Bagaimana cara mengubah angka dalam ()untuk mencerminkan nomor yang hanya terkait dengan penulis?

Inilah yang saya gunakan:

// 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']);

        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"' : '';

        endif;
    }
    return $views;

Jalan terbaik

SEMUA JAWABAN INI MEMILIKI MASALAH KEAMANAN.

Cara terbaik adalah menambahkan kemampuan kustom dan mengelola pos dll dengan kemampuan.

Cara yang mudah

Solusi Artem tampaknya lebih baik karena WP tidak merujuk jumlah posting hanya pada layar post edit tetapi juga dalam widget Dashboard, respons Ajax dll.

Untuk solusi yang lebih baik berdasarkan Artem's.

1. hapus cache jumlah posting default.
   mengapa: wp_count_postssebelumnya mengembalikan jumlah cache yang dihitung ketika hasilnya telah di-cache sebelumnya.
2. cache hasil hitungan pos kustom.
   mengapa: cache meningkatkan kinerja.
3. hargai $permparameter ke-3 wp_count_postshook.
   mengapa: jumlah posting harus mencakup posting pribadi pengguna sendiri berdasarkan readableperm.
4. terapkan filter sebagai filter prioritas tinggi.
   mengapa: filter mungkin ditimpa oleh filter lain.
5. menghapus (atau memodifikasi) jumlah posting yang lengket.
   mengapa: posting sticky menghitung termasuk posting lain dan mereka dihitung secara terpisah oleh WP_Posts_List_Table.
6. gunakan kemampuan yang tepat untuk Jenis Posting Kustom
   mengapa: read_others_postskemampuan dapat dimodifikasi.

Anda mungkin ingin menambahkan tweak

• filter komentar posting orang lain dengan menyetel post_authorkueri var ke WP_Comment_Query.
• komentar tweak dihitung dengan wp_count_commentskait.
• mencegah akses ke layar admin yang seharusnya dibatasi.

Berikut ini adalah versi yang dimodifikasi berdasarkan wp_post_counts()WP 4.8.

function clear_cache() {
    // deletes the default cache for normal Post. (1)
    $cache_key = _count_posts_cache_key( 'post' , 'readable' );
