我正在开发一个创建列表的插件。创建列表后，我想从url中删除slug
岗位类型：
$rewrite = [
\'slug\' => \'single-link\',
\'with_front\' => false,
\'pages\' => false,
\'feeds\' => false,
];
$args = [
\'label\' => esc_html__( \'Single Link\', \'single-link\' ),
\'labels\' => $labels,
\'supports\' => [ \'title\' ],
\'hierarchical\' => false,
\'public\' => true,
\'show_ui\' => true,
\'show_in_menu\' => true,
\'menu_position\' => 15,
\'menu_icon\' => \'dashicons-admin-links\',
\'show_in_admin_bar\' => false,
\'show_in_nav_menus\' => true,
\'can_export\' => true,
\'has_archive\' => false,
\'exclude_from_search\' => true,
\'publicly_queryable\' => true,
\'rewrite\' => $rewrite,
\'capability_type\' => \'page\',
\'show_in_rest\' => true,
];
$args = apply_filters( \'single-link/post_type/args\', $args );
register_post_type( \'single-link\', $args );
从URL中删除段塞：
function remove_cpt_slug( $post_link, $post, $leavename ) {
if ( \'single-link\' != $post->post_type || \'publish\' != $post->post_status ) {
return $post_link;
}
$post_link = str_replace( \'/\' . $post->post_type . \'/\', \'/\', $post_link );
return $post_link;
}
add_filter( \'post_type_link\', \'remove_cpt_slug\', 10, 3 );
function change_slug_struct( $query ) {
if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query[\'page\'] ) ) {
return;
}
if ( ! empty( $query->query[\'name\'] ) ) {
$query->set( \'post_type\', array( \'post\', \'single-link\', \'page\' ) );
}
}
add_action( \'pre_get_posts\', \'change_slug_struct\' );

现在点击publish后，slug/single-link/被删除，但我们在访问页面时总是得到404。更改/重新保存永久链接没有帮助。我做错了什么？

自定义post类型的注册和permalink修改是可以的。问题在于WordPress重写规则很可能会匹配到页面的简单链接的“清理”URL，它会设置pagename 查询var notname 作为您的change_slug_struct() 假定的功能。
因此，将函数更改为此以考虑所有情况：
function change_slug_struct( $query ) {
if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query[\'page\'] ) ) {
return;
}
if ( ! empty( $query->query[\'name\'] ) ) {
$query->set( \'post_type\', array( \'post\', \'single-link\', \'page\' ) );
} elseif ( ! empty( $query->query[\'pagename\'] ) && false === strpos( $query->query[\'pagename\'], \'/\' ) ) {
$query->set( \'post_type\', array( \'post\', \'single-link\', \'page\' ) );
// We also need to set the name query var since redirect_guess_404_permalink() relies on it.
$query->set( \'name\', $query->query[\'pagename\'] );
}
}
add_action( \'pre_get_posts\', \'change_slug_struct\' );
