En termes simples, comment masquer complètement les fichiers multimédias téléchargés par d’autres utilisateurs que par eux-mêmes? Je voudrais désactiver l’accès à ces liens et fichiers, car ils sont un moyen pour les utilisateurs non-administrateurs d’être en mesure d’accéder et de modifier un type de publication personnalisé qui ne leur est normalement pas visible sinon dans le backend de Wordpress.
Remarque: je voudrais toujours qu'ils puissent télécharger et éditer leurs "propres" fichiers multimédias simplement pour être clair.
En fait, vous pouvez, et voici comment faire:
Ce code masque tous les messages et les médias n'appartenant pas à l'auteur actuellement connecté (vous pouvez le modifier pour l'appliquer à d'autres rôles d'utilisateur). Il corrige également le nombre de publications et de médias sur les barres de filtres (par exemple, Tous | Images | Vidéos | Non associé).
// 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;

return $views;
}
Celui-ci est beaucoup plus facile à ajouter sur le functions.php et fonctionne comme un charme:
function hide_media_by_other($query) {
global $pagenow;
if( 'upload.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', 'hide_media_by_other');

Cordialement, phpbits
Pour que la solution de Paul fonctionne avec ACF, modifiez simplement la première fonction en:
function current_author_posts( $wp_query ) {
if ( strpos( admin_url(), '/edit.php' ) !== false ) {
if ( !current_user_can( 'delete_pages' ) ) {
global $current_user;
$wp_query->set( 'author', $current_user->ID );
add_filter('views_edit-post', 'fix_post_counts');
add_filter('views_upload', 'fix_media_counts');
}
}
}
add_filter('parse_query', 'current_author_posts' );
