いくつかの作業コードを圧縮/最適化するのに役立ちます

デフォルトではWordPressは著者であるユーザーにすべての投稿を表示します。私は著者が自分の投稿を見ることしかできないようにしたかったので、うまく機能する次のコードを思いついた。

それを凝縮/最適化するための提案はありますか？

// Only show posts related to current 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 );
    }
}

// Check that user is not an Administrator
if (!current_user_can('promote_users')) {
    add_filter('views_edit-post', 'remove_mine');
    add_filter('views_edit-post', 'posts_all');
    add_filter('views_edit-post', 'posts_published');
    add_filter('views_edit-post', 'posts_draft');
    add_filter('views_edit-post', 'posts_pending');
    add_filter('views_edit-post', 'posts_trash');
}

// Remove "Mine" from filter bar
function remove_mine( $views ) {
    unset($views['mine']);
    return $views;
}

// Fix "All" post count to only include posts related to current author
function posts_all($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == NULL ) $class = ' class="current"';
    $link = sprintf(__('<a href="%s"'.$class.'>All <span class="count">(%d)</span></a>', 'all'),
            admin_url('edit.php?post_type=post'),
            $result->found_posts);
    $views['all'] = $link;
    return $views;
}

// Fix "Published" post count to only include posts related to current author
function posts_published($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'publish',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'publish' ) $class = ' class="current"';
    $link = sprintf(__('<a href="%s"'.$class.'>Published <span class="count">(%d)</span></a>', 'publish'),
            admin_url('edit.php?post_status=publish&post_type=post'),
            $result->found_posts);
    $views['publish'] = $link;
    return $views;
}

// Fix "Drafts" post count to only include posts related to current author
function posts_draft($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'draft',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'draft' ) $class = ' class="current"';
        $link = sprintf(__('<a href="%s"'.$class.'>Draft'.((sizeof($result->posts)>1)?"s":"").' <span class="count">(%d)</span></a>', 'draft'),
            admin_url('edit.php?post_status=draft&post_type=post'),
            $result->found_posts);
    $views['draft'] = $link;
    return $views;
}

// Fix "Pending" post count to only include posts related to current author
function posts_pending($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'pending',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'pending' ) $class = ' class="current"';
        $link = sprintf(__('<a href="%s"'.$class.'>Pending <span class="count">(%d)</span></a>', 'pending'),
            admin_url('edit.php?post_status=pending&post_type=post'),
            $result->found_posts);
    $views['pending'] = $link;
    return $views;
}

// Fix "Trash" post count to only include posts related to current author
function posts_trash($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'trash',

    return $views;
}

わかりました。これが最適化されたコードです。

// Show only posts related to current user
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');
    }
}

// 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'),
                admin_url('edit.php?post_type=post'),
                $result->found_posts);
        elseif( $type['status'] == 'publish' ):
            $class = ($wp_query->query_vars['post_status'] == 'publish') ? ' class="current"' : '';
            $views['publish'] = sprintf(__('<a href="%s"'. $class .'>Published <span class="count">(%d)</span></a>', 'publish'),
                admin_url('edit.php?post_status=publish&post_type=post'),
                $result->found_posts);
        elseif( $type['status'] == 'draft' ):
            $class = ($wp_query->query_vars['post_status'] == 'draft') ? ' class="current"' : '';
            $views['draft'] = sprintf(__('<a href="%s"'. $class .'>Draft'. ((sizeof($result->posts) > 1) ? "s" : "") .' <span class="count">(%d)</span></a>', 'draft'),
                admin_url('edit.php?post_status=draft&post_type=post'),
                $result->found_posts);
        elseif( $type['status'] == 'pending' ):
            $class = ($wp_query->query_vars['post_status'] == 'pending') ? ' class="current"' : '';
            $views['pending'] = sprintf(__('<a href="%s"'. $class .'>Pending <span class="count">(%d)</span></a>', 'pending'),
                admin_url('edit.php?post_status=pending&post_type=post'),
                $result->found_posts);
        elseif( $type['status'] == 'trash' ):
            $class = ($wp_query->query_vars['post_status'] == 'trash') ? ' class="current"' : '';
            $views['trash'] = sprintf(__('<a href="%s"'. $class .'>Trash <span class="count">(%d)</span></a>', 'trash'),
                admin_url('edit.php?post_status=trash&post_type=post'),
                $result->found_posts);
        endif;
    }
    return $views;
