Lightweight, accessible popups for WordPress—made by developers, for developers.

== Description ==

**Emberly Popups** is a simple PHP function that generates ARIA‑compliant modal popups. Great for newsletters, surveys, announcements, or any call‑to‑action:

* Auto‑open after a configurable delay  
* Cookie‑ or session‑based “show once” control  
* Repeat interval (milliseconds) between popups  
* Shortcode support inside popup content  
* Adjustable width and padding  
* Accessible markup with proper ARIA roles

== Installation ==

1. Copy the **emberly_popup()** function into your theme’s `functions.php` or a custom plugin.  
2. Enqueue or include the popup’s CSS and JS assets.  
3. Ensure `assets/icons/close.svg` exists (used for the close button).  
4. Call `emberly_popup()` anywhere in your PHP templates.

== Usage ==

=== PHP 8+ (named arguments) ===
```php
emberly_popup(
    title            : 'Welcome!',
    content          : '<p>Thanks for visiting our site. Don’t miss our latest offers!</p>',
    id               : 'welcome-popup',
    width            : '50rem',
    padding          : '3rem',
    echo             : true,
    output_shortcodes: true,
    auto_open        : true,
    delay            : 2000,
    show_once        : false,
    persistence_method: 'session',
    show_interval_ms : 1800000  // 30 minutes
);
```

=== PHP 7 & earlier (ordered arguments) ===
```php
emberly_popup(
    '',                               // $title
    '<p>Thanks for visiting our site. Don't miss our latest offers!</p>',
    'category-survey-popup',          // $id
    '50rem',                          // $width
    '3rem',                           // $padding
    true,                             // $echo
    true,                             // $output_shortcodes
    true,                             // $auto_open
    2000,                             // $delay
    false,                            // $show_once
    'session',                        // $persistence_method
    1800000                           // $show_interval_ms
);
```

=== Manual triggers ===  
Anywhere in your markup, add:
```html
<a href="#" em-popup-trigger-id="welcome-popup">Open Welcome Popup</a>
```
The `em-popup-trigger-id` value must match the `$id` you set in `emberly_popup()`.

== Debugging ==

Add `debug: true` (PHP 8+) or append `true` as the 13th argument (PHP 7) to enable console logging:

```php
// PHP 8+ example
emberly_popup(
    title : 'Debug Popup',
    content: '<p>Debugging is on!</p>',
    id    : 'debug-popup',
    debug : true
);
```

== Frequently Asked Questions ==

= What if I don’t set an ID? =
An ID is required for cookies/sessions and manual triggers; omit at your own risk.

= Can I use shortcodes in my popup? =
Yes—set `output_shortcodes` to `true`.
