| 34 | + * instantiated on the front-end `wp` hook ). Called once from ThemeBuilder's | |
| 35 | + * constructor. | |
| 36 | + * | |
| 37 | + * Three independent render pathways need their own switch, because none of | |
| 38 | + * them share a common choke point: | |
| 39 | + * - Real front end / live preview iframe: Document::get_content() -> | |
| 40 | + * Frontend::get_builder_content(). This is a normal front-end request, so | |
| 41 | + * it WOULD also be reachable from a `wp`-gated instance, but is registered | |
| 42 | + * here too for symmetry with the pathways below and so both share one stack. | |
| 43 | + * - Editor admin page bootstrap ( post.php?action=elementor, which never | |
| 44 | + * fires the `wp` action ): Document::get_config() bakes each widget's | |
| 45 | + * server-rendered `render()` output into `ElementorConfig.initial_document` | |
| 46 | + * as `htmlCache` via get_elements_raw_data( null, true ), fired right after | |
| 47 | + * `before_get_config`. This does NOT go through Frontend::get_builder_content() | |
| 48 | + * at all, so it needs its own switch/restore pair. | |
| 49 | + * - Adding a widget to the LIVE canvas ( no save/reload in between ): a PHP-only | |
| 50 | + * widget with no JS `content_template()` — every EA Woo widget, and most of | |
| 51 | + * ours — is rendered via the `render_widget` ajax action | |
| 52 | + * ( Widgets_Manager::ajax_render_widget() -> Document::render_element() ), | |
| 53 | + * which goes through NEITHER get_content() NOR get_config(). Confirmed by | |
| 54 | + * direct testing: dropping one of these widgets onto a brand-new, unsaved | |
| 55 | + * product_single template shows the widget's placeholder until the whole | |
| 56 | + * document is reloaded ( which bakes via get_config() and so IS covered ) — | |
| 57 | + * reloading immediately after masks the gap, which is why it wasn't caught | |
| 58 | + * sooner. | |
| 59 | + * | |
| 60 | + * Two other approaches were tried and confirmed NOT to work, by direct | |
| 61 | + * testing with temporary logging (kept here so the next person doesn't | |
| 62 | + * re-walk the same dead ends): | |
| 63 | + * - Switching the query earlier ( e.g. on `wp_ajax_elementor_ajax` ), on the | |
| 64 | + * theory that `ajax_render_widget()`'s own `query_posts( [ 'p' => | |
| 65 | + * $editor_post_id, 'post_type' => 'any' ] )` (widgets.php) would silently | |
| 66 | + * undo it. Red herring: `query_posts()` only replaces `$wp_query` — it | |
| 67 | + * does NOT touch `global $post` at all ( that only happens via | |
| 68 | + * `the_post()` / `setup_postdata()`, neither of which `ajax_render_widget()` | |
| 69 | + * calls on its query ) — confirmed via a `the_posts` filter showing the | |
| 70 | + * query itself resolving to the right product while `$GLOBALS['post']` | |
| 71 | + * stayed on the templately_library document throughout. | |
| 72 | + * - Rewriting that same `query_posts()` query via `pre_get_posts`. The query | |
| 73 | + * rewrite itself worked ( confirmed the SQL fetched the preview product | |
| 74 | + * correctly ) but was moot for the same reason: since `query_posts()` | |
| 75 | + * never touches `global $post`, redirecting it changes nothing observable. | |
| 76 | + * | |
| 77 | + * The actual cause: `Ajax\Module::handle_ajax_request()` calls | |
| 78 | + * `Plugin::$instance->db->switch_to_post( $editor_post_id )` — which DOES | |
| 79 | + * directly set `$GLOBALS['post']` + `setup_postdata()` — *before* dispatching | |
| 80 | + * to any registered action (including `render_widget`), and nothing after | |
| 81 | + * that point ever touches `global $post` again. So the fix has to override | |
| 82 | + * `global $post` a second time, strictly *after* that call. `elementor/ajax/ | |
| 83 | + * register_actions` fires right after it and before the action dispatch loop | |
| 84 | + * — see maybe_switch_global_post_for_ajax_render(). No restore needed: this | |
| 85 | + * is a one-shot admin-ajax.php process that exits right after responding. | |
