问题描述
我打算运行一个 multi-author 站点,我不想让其他作者的帖子显示在/wp-admin/edit.php
页面中。
我通过 this thread 的代码来管理这个问题。代码如下:
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');
代码工作很好,它隐藏了其他作者的帖子,以便在这里显示。但是我确实发现另一个问题 – 页面顶部的菜单不会改变作者相关的帖子数量,它显示了我网站上所有帖子的数量。
菜单我的意思是这样的:
Mine () | All () | Published () | Draft () | Trash ()
如何更改 ()
中的数字以反映与作者相关的数字?
最佳解决方案
这是我使用的:
// 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'),
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 $views;
}
// Fix media counts
function fix_media_counts($views) {
global $wpdb, $current_user, $post_mime_types, $avail_post_mime_types;
$views = array();
$count = $wpdb->get_results( "
SELECT post_mime_type, COUNT( * ) AS num_posts
FROM $wpdb->posts
WHERE post_type = 'attachment'
AND post_author = $current_user->ID
AND post_status != 'trash'

", ARRAY_A );
foreach( $count as $row )
$_num_posts[$row['post_mime_type']] = $row['num_posts'];
$_total_posts = array_sum($_num_posts);
$detached = isset( $_REQUEST['detached'] ) || isset( $_REQUEST['find_detached'] );
if ( !isset( $total_orphans ) )
$total_orphans = $wpdb->get_var("
SELECT COUNT( * )
FROM $wpdb->posts
WHERE post_type = 'attachment'

AND post_status != 'trash'
AND post_parent < 1
");
$matches = wp_match_mime_types(array_keys($post_mime_types), array_keys($_num_posts));
foreach ( $matches as $type => $reals )
foreach ( $reals as $real )
$num_posts[$type] = ( isset( $num_posts[$type] ) ) ? $num_posts[$type] + $_num_posts[$real] : $_num_posts[$real];
$class = ( empty($_GET['post_mime_type']) && !$detached && !isset($_GET['status']) ) ? ' class="current"' : '';
$views['all'] = "<a href='upload.php'$class>" . sprintf( __('All <span class="count">(%s)</span>', 'uploaded files' ), number_format_i18n( $_total_posts )) . '</a>';
foreach ( $post_mime_types as $mime_type => $label ) {
$class = '';
if ( !wp_match_mime_types($mime_type, $avail_post_mime_types) )
continue;
if ( !empty($_GET['post_mime_type']) && wp_match_mime_types($mime_type, $_GET['post_mime_type']) )
$class = ' class="current"';
if ( !empty( $num_posts[$mime_type] ) )
$views[$mime_type] = "<a href='upload.php?post_mime_type=$mime_type'$class>" . sprintf( translate_nooped_plural( $label[2], $num_posts[$mime_type] ), $num_posts[$mime_type] ) . '</a>';
}
$views['detached'] = '<a href="upload.php?detached=1"' . ( $detached ? ' class="current"' : '' ) . '>' . sprintf( __( 'Unattached <span class="count">(%s)</span>', 'detached files' ), $total_orphans ) . '</a>';
return $views;
}
次佳解决方案
基于答案 https://wordpress.stackexchange.com/a/49200/83038 的较短的解决方案。
注意:自 WordPress 3.7.0 起可用。
function fix_count_orders( $counts, $type ) {
global $wpdb;
$query = "SELECT post_status, COUNT( * ) AS num_posts FROM {$wpdb->posts} WHERE post_type = %s";
$query .= $wpdb->prepare( " AND post_author = %d", get_current_user_id() );
$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 ) {
global $current_user;
// Add here post types for which you want to fix counts ('post' added for example).
$allowed_types = array( 'post' );
$current_type = get_query_var( 'post_type' ) ? get_query_var( 'post_type' ) : '';
if( is_admin() && ! current_user_can( 'edit_others_posts' ) && in_array( $current_type, $allowed_types ) ) {
$wp_query->set( 'author', $current_user->ID );
add_filter( 'wp_count_posts', 'fix_count_orders' );
}
}
add_action( 'pre_get_posts', 'query_set_only_author', 10, 2 );
