Site Editor: Avoid client side redirection in initial load #36873
Description
Site Editor sets current page context and handles context-based redirection on the client; see URLQueryController. Parts of this logic can be moved on server-side and passed to the editor during initialization.
- Create a function to generate context on the server. See the basic example below.
- Handle all context-related global state using a single action/selector, probably based on
setPage. - Try to find better alternative for
__experimentalGetTemplateForLinkselector.
Basic Example
function gutneberg_get_page_context() {
$context = [];
$id = isset( $_GET['postId'] ) ? $_GET['postId'] : null;
$type = isset( $_GET['postType'] ) ? $_GET['postType'] : null;
$type_obj = get_post_type_object( $type );
if ( ! $type_obj ) {
return $context;
}
if ( in_array( $type_obj->name, [ 'wp_template', 'wp_template_part' ], true ) ) {
$template = gutenberg_get_block_template( $id, $type_obj->name );
if ( ! $template ) {
return $context;
}
return [
'id' => $template->id,
'type' => $template->type,
'page' => [
'templateSlug' => $template->slug,
],
];
}
}
