ID Popup

1.5

Released: March 2026
* Updated short description and tags.
* Synchronised plugin version with stable tag.

1.4

Security Hardening
* Added wp_die() after wp_send_json_error() in AJAX handler to prevent continued execution after unauthorized access.
* Whitelisted the type parameter in the AJAX search handler against known post types — unknown types are rejected with wp_die().
* Switched popup_link sanitization from sanitize_text_field() to esc_url_raw() — correct WordPress standard for URL fields stored in the database.
* Added strict allowlist validation for display_rules using in_array() with type checking.
* Cast all specific_ids to integers using intval — eliminates any possibility of string injection through ID fields.
* Applied esc_html() to post titles and absint() to IDs in AJAX JSON responses.
* Applied esc_attr() to desktop_max_width in inline style output.

Bug Fixes
* Fixed auto-close value of 0 not working — parseInt(0) || 15000 was incorrectly evaluating to 15000. Now uses isNaN() check so 0 correctly disables auto-close.
* Fixed mobile skip logic — data() returns a string but was compared with === 0 (integer). Wrapped with parseInt() for correct type coercion.
* Fixed scheduling logic — previously required both start AND end dates to evaluate; now each date boundary is checked independently.
* Removed dead $preview_style PHP variable that was computed but never used.

Performance
* Added no_found_rows: true and update_post_term_cache: false to the frontend WP_Query to skip unnecessary database queries.
* Popup HTML is now skipped in PHP entirely if neither desktop nor mobile images are set.

1.3

Released: March 2026

New: WooCommerce Display Rules
* Added All Product Pages display rule — shows popup on any WooCommerce single product page.
* Added Specific Product Page(s) display rule — target individual WooCommerce products by name using the Select2 search interface.
* WooCommerce rules are only rendered in the admin dropdown when WooCommerce is active (class_exists(‘WooCommerce’)).
* AJAX search handler now supports product post type when specific_products rule is selected.

Select2 Improvements
* Placeholder text dynamically updates based on selected display rule: “Search pages…”, “Search posts…”, or “Search products…”.
* Select2 search field now appears for specific_products rule in addition to specific_pages and specific_posts.

Display Rule Precision
* “All Single Posts” now uses is_singular(‘post’) instead of is_single() — correctly excludes custom post types and WooCommerce products.
* “Specific Post(s)” rule now uses is_singular(‘post’) + get_queried_object_id() matching — consistent with the specific pages and products pattern.
* “Specific Page(s)” now uses get_queried_object_id() for ID matching instead of passing an array to is_page().

1.2

Released: March 2026

Multiple Popups Architecture (Major Feature)
* Migrated from a single WordPress Options API settings page to a Custom Post Type (id_popup).
* Each popup is now an independent WordPress post with its own title, settings, and lifecycle.
* Added dedicated Popups menu item in the WordPress admin sidebar with a custom dashicon.
* Three separate native WordPress Meta Boxes replace the single settings form: Media Setup, Display Rules & Scheduling, and Appearance & Behavior.
* Meta box headers styled with the plugin’s red theme using CSS targeting native WP postbox elements.
* Added automatic one-time data migration from the old id_popup_settings option into a new “Default Popup” post — no data loss on upgrade.

Frontend Multi-Popup Support
* Frontend now uses WP_Query to loop all published id_popup posts.
* Each popup evaluated independently for scheduling and display rules.
* HTML output switched from singleton IDs (#id-popup) to classes (.id-popup-container, .id-popup-overlay) to support multiple simultaneous popups on one page.
* Per-popup delay and auto-close timings passed via data-delay and data-autoclose attributes — no global JS variables.

Image Handling
* Each popup independently skips rendering if no image is configured for the current device type.
* Device detection (data-has-desktop, data-has-mobile) evaluated fresh per popup per page load.

1.1

Released: March 2026

WordPress Media Library Integration
* Replaced plain URL input fields with the native WordPress Media Uploader.
* Plugin now stores WordPress Attachment IDs instead of raw image URLs — more robust, survives media library reorganization.
* Image URLs are dynamically resolved at render time using wp_get_attachment_image_url().
* Added attachment_url_to_postid() fallback for any legacy string URL values still in the database.
* Added live image previews in the admin for both desktop and mobile images.
* Added remove (×) button on image thumbnails — clears the attachment ID and hides the preview without a page reload.

Display Rules Expansion
* Added All Pages display rule.
* Added All Single Posts display rule.
* Added Specific Page(s) display rule with Select2 live search.
* Added Specific Post(s) display rule with Select2 live search.
* “Specific Page/Post” field dynamically shows/hides based on the selected rule (hidden by default).

Select2 Integration
* Integrated Select2 library for the specific page/post ID selection.
* AJAX-powered live search for pages and posts.
* Selected items displayed as removable pill tags.
* Automatically clears selections when an incompatible display rule is chosen.

Field Defaults
* Desktop Max Width defaults to 900px.
* Auto Close defaults to 15 seconds.
* Delay Before Opening defaults to 3 seconds.
* Target URL defaults to #.
