Retrieve and display any WordPress data with shortcodes — posts, users, options, and more, with flexible formatting and customization.

== Description ==

A powerful WordPress plugin that lets you retrieve and display virtually any data in WordPress using simple shortcodes. Effortlessly pull information from posts, users, options, and more — with support for dynamic attribute parsing, flexible formatting, and customizable output wrapping.

It supports:
- Post Field
- Post Meta
- Term Field
- Term Meta (coming soon)
- User Field
- User Meta
- Link
- Option
- Function (whitelisted)

You can also:
- Apply custom formatting (date, datetime, number, capitalize, uppercase, lowercase, strip_tags, etc.)
- Add before/after text
- Use fallback values
- Use nested shortcodes inside attributes
- Use URL parameters as values
- Cache output
- Secure and sanitize output

== Installation ==

1. Upload the plugin folder to `/wp-content/plugins/`.
2. Activate the plugin via the "Plugins" menu in WordPress.
3. Use the `[anys]` shortcode anywhere you want.

== Shortcode Usage ==

**General syntax:**
```
[anys type="TYPE" name="KEY" id="ID" before="TEXT" after="TEXT" fallback="TEXT" format="FORMAT" delimiter="DELIMITER"]
```

**Attributes:**

Notes:
- Only functions whitelisted in plugin settings can be executed.
- Arguments can include other `[anys]` shortcodes using `()` instead of `[]`.
- Output can be formatted or wrapped with `before`/`after` content and fallback.

== Dynamic Attribute Parsing ==
Supports dynamic placeholders inside attribute values:
- `{get:param}` — gets value from $_GET['param']
- `{post:param}` — gets value from $_POST['param']
- `{func:function_name,arg1,arg2}` — calls a whitelisted PHP function
- `{shortcode:(tag)}` — parses nested shortcode (use `()` instead of `[]`)
- `{const:CONSTANT_NAME}` — replaces with PHP constant value

Example:
```
[anys type="post_field" name="post_title" id="{get:post_id}" before="Title: "]
```

== Formatting Options ==
- `date` — Format timestamps using WordPress date format.
- `datetime` — Format timestamps using WordPress date and time format.
- `number` — Localized number format.
- `json` — Encode value as JSON string.
- `serialize` — Serialize PHP value.
- `unserialize` — Unserialize string if serialized.
- `print_r` — Human-readable output of variable.
- `var_export` — Parsable string representation.
- `implode` — Join array values.
- `values` — Join array values only.
- `keys` — Join array keys only.
- `keys_values` — Join array key-value pairs.
- `capitalize` — Capitalize words.
- `uppercase` — Uppercase all characters.
- `lowercase` — Lowercase all characters.
- `strip_tags` — Remove HTML/PHP tags.

Custom formats are supported via filters.

== Hooks ==

**Filters**
- `anys/attributes` — Filter attributes before processing.
- `anys/{type}/attributes` — Filter attributes dynamically by type.
- `anys/output` — Filter final output.
- `anys/{type}/output` — Filter output dynamically by type.
- `anys/link/handlers` - Filter link handlers.

**Actions**
- `anys/output/before` — Fires before output.
- `anys/{type}/output/before` — Fires before output for specific type.
- `anys/{type}/missing` — Fires when handler file missing.
- `anys/output/after` — Fires after output.
- `anys/{type}/output/after` — Fires after output for specific type.

== Security ==
- All inputs sanitized using WordPress functions.
- Function calls restricted to whitelisted list.
- Outputs sanitized with `wp_kses_post()`.
- Dynamic parsing uses caching for performance.
