Real-time search & replace for text, HTML, and URLs. Target elements, post types, IDs, or URLs. Safely remove footer credit — no database changes.

== Description ==
The **Easy Search Replace** plugin lets you **find and replace** any text, HTML, or URL across your WordPress site in real time — without editing files or the database.
It’s the safest way to do **search and replace** on front-end output. Update branding, fix old links, or **remove footer credit** with a few clicks.

Target replacements precisely with:

- CSS selectors (e.g., `.footer`, `#site-title`, `h2`)
- Post Types (Posts, Pages, CPTs)
- Specific Post IDs (comma separated)
- Exact URLs (one per line)

**Why it’s safe:**
All changes are applied dynamically at render time. Disable the plugin and your original content is unchanged.

**Popular use cases**

- Remove or replace theme footer credits.
- Replace company names, links, or copyright lines.
- Update outdated or HTTP → HTTPS URLs.
- Find/replace only inside specific HTML elements.
- Limit changes to selected posts/pages/URLs.

== Features ==
- Real-time **search replace** and **find replace** for text, HTML, and URLs.
- Remove footer credit or any unwanted text/link.
- Optional **CSS selector** targeting (classes, IDs, tags).
- Limit by **post type**, **post ID**, or **URL**.
- Case-insensitive mode (Ignore Case).
- Multiple rules, executed in order.
- Lightweight: parses the DOM only when selector rules exist.
- Clean, simple settings UI.

== Installation ==
1. Download the plugin ZIP.
2. In WP Admin, go to **Plugins → Add New → Upload Plugin**.
3. Upload the ZIP, click **Install Now**, then **Activate**.
4. Go to **Settings → Easy Search Replace** to add rules.

== Usage ==
1. Open **Settings → Easy Search Replace**.
2. **Find**: Enter the text/HTML/URL to search.
3. **Replace with**: Enter the replacement (leave empty to remove — great for footer credits).
4. *(Optional)* **CSS Selector** to restrict to specific elements (e.g., `.site-footer`, `#main`, `h1`).
5. *(Optional)* Limit by **Post Types**, **Post IDs**, or **URLs** (one per line).
6. Enable **Ignore case** if needed.
7. Add multiple rules and **Save Changes**.

== Examples ==
**Replace text globally**

Find: Old Company
Replace: New Company

**Remove footer credit (selector-based)**

Find: Powered by MyTheme
Replace:
Selector: .site-footer

**Replace URL site-wide**

Find: http://oldsite.com
Replace: https://newsite.com

**Only on specific posts**

Find: Coming Soon
Replace: Launching Now
Post IDs: 25,47,88

**Case-insensitive**
Enable **Ignore case** to match “WordPress”, “wordpress”, etc.

== Frequently Asked Questions ==
= Does this modify my database or theme files? =
No. All replacements happen in the output buffer at runtime.

= Can I remove theme footer credits? =
Yes. Put the exact text in **Find**, leave **Replace** empty, and (optionally) set a footer **CSS Selector** (e.g., `.footer-credit`).

= Will it work with page builders and caching? =
Yes. It works on rendered HTML (Elementor, Divi, WPBakery, etc.). Clear your cache after adding or updating rules.

= Performance impact? =
Minimal. String replacements are fast; DOM parsing only happens if you use selector-based rules.

= Regex support? =
Not in this version — by design for speed and simplicity.

== Changelog ==

= 1.1.4 =
* Minor issues fixed.

= 1.1.3 =
* Security: sanitize and unslash `$_SERVER['REQUEST_URI']` when resolving the current URL for rule matching.
* Security: wrap every `$_POST` access in explicit `isset()` + `is_array()` checks and `wp_unslash()` calls; stop mutating the `$_POST` superglobal.
* Security: validate post-ID input as integers instead of a regex strip, and validate URL lines via `esc_url_raw` for absolute URLs.
* Security: use `get_current_screen()` hook-suffix matching instead of `$_GET['page']` to decide when to enqueue admin assets.
* Security: explicit capability check with `wp_die` on the settings screen, in addition to the menu capability.
* Bug fix: rules limited to specific post types no longer match on non-singular views (archives, search, 404).
* Dev: introduced `ESRN_VERSION`, `ESRN_PLUGIN_DIR`, `ESRN_PLUGIN_URL`, `ESRN_PLUGIN_BASENAME`, and `ESRN_OPTION_KEY` constants; asset versions now track the plugin version.
* Dev: `load_plugin_textdomain()` is now called on `plugins_loaded`.
* UI: redesigned settings screen with a responsive two-column layout, rule cards, inline help, and a sticky "How it works" side panel.
* UI: improved focus states, keyboard/Select2 accessibility, and visual consistency with WordPress core admin.
