## Descrizione

A minimal way to inject a single inline JavaScript snippet into the `<head>` of 
one or more specific posts, pages or products. You give it a comma-separated list
of post IDs and the JS body — that is the entire surface area.

The point is the absence of features. There is no per-post UI, no script library,
no CDN selector, no “fire on event” toggle. If all you need is to drop a tracking
pixel or a tiny script on three specific pages, you do not want a 2 MB plugin that
wants to manage your whole site.

Set it up under **Settings  Lightweight JS snippet**. The page provides a textarea
for the JS (no `<script>` tags — those are added for you) and a comma-separated 
list of post IDs to load it on.

## Installazione

 1. Upload `/lightweight-js-snippet/` to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the Plugins menu in WordPress.
 3. Go to **Settings  Lightweight JS snippet** and paste in your JS plus the post IDs.

## FAQ

### Where does the script run?

It is printed inline in the `<head>` of the listed posts/pages, only.

### Can I add “ tags?

No — they are added for you. Only paste the JS body.

### Does it support more than one page?

Yes. Use a comma-separated list of post IDs. Search for the post name in the settings
page to find the ID automatically.

## Changelog

#### 1.4.1

 * Fix empty `<script id="jhljs-script">` tag rendered on every page when no snippet
   was configured. Logic error (`||` where `&&` was meant) plus no early-return 
   on empty options.
 * Fix Settings link on the Plugins screen — previous filter targeted the wrong 
   plugin basename, and the URL pointed at a non-existent menu slug. Both corrected.

#### 1.4

 * Settings page now lets you pick target posts/pages by typing their title — the“
   comma-separated post IDs” textbox is replaced with a chip-style picker. Two small
   REST endpoints (`jhljs/v1/posts`, `jhljs/v1/search`) gated to `manage_options`
   power the lookup and search.

#### 1.3

 * Sanitize the post-id list and the JS snippet on save via `register_setting()`
   callbacks (digits/commas/whitespace for the IDs, `wp_kses` `'data'` for the script—
   same filter that was already applied on output).
 * Escape every translated string in the settings UI (`_e()`/`__()`  `esc_html_e()`/`
   esc_html__()`) and use `esc_textarea()` for the snippet field.
 * Add the missing `License`, `License URI` and `Text Domain` headers, fix the text-
   domain mismatches, and add an explicit version to `wp_enqueue_script()`.
 * Bumped minimum PHP to 7.4. Tested up to WordPress 6.9.

#### 1.2

 * Bugfix when escaping script.

#### 1.1

 * Code editor added.
 * Support for multiple ids.
 * Securing plugin.

#### 1.0

 * Initial release.
