AJAX Action Wrapper
===================

[](#ajax-action-wrapper)

This helper library makes it easier to handle AJAX requests in WordPress plugins. Mainly for personal use.

### Example

[](#example)

Define action:

```
$exampleAction = ajaw_v1_CreateAction('ws_do_something')
	->handler(array($this, 'myAjaxCallback'))
	->requiredCap('manage_options')
	->method('post')
	->requiredParam('foo')
	->optionalParam('bar', 'default value')
	->register();
```

Call from JavaScript:

```
AjawV1.getAction('ws_do_something').post(
	{
		'foo': '...'
	},
	function(response) {
		console.log(response);
	}
);
```

### Features

[](#features)

- Automate common, boring stuff.
    - Automatically pass the `admin-ajax.php` URL and nonce to JS.
    - Define required parameters. ```
         $builder->requiredParam('foo', 'int')
        ```
    - Define optional parameters with default values. ```
         $builder->optionalParam('meaningOfLife', 42, 'int')
        ```
    - Automatically remove "magic quotes" that WordPress adds to `$_GET`, `$_POST` and `$_REQUEST`.
    - Encode return values as JSON.
- Security should be the default.
    - Generate and verify nonces. Nonce verification is on by default, but can be disabled. ```
         $builder->withoutNonce()
        ```
    - Check capabilities. ```
         $builder->requiredCap('manage_options');
        ```
    - Verify that all required parameters are set.
    - Validate parameter values. ```
         $builder->optionalParam('things', 1, 'int', function($value) {
         	if ($value > 10) {
         		return new WP_Error(
         			'excessive_things',
         			'Too many things!',
         			400 //HTTP status code.
         		);
         	}
         })
        ```
    - Set the required HTTP method. ```
         $builder->method('post')
        ```
- Resilience.
    - Lenient response parsing to work around bugs in other plugins. For example, deal with extraneous whitespace and PHP notices in AJAX responses.
    - Multiple versions of the library can coexist on the same site.

### Why not use the REST API instead?

[](#why-not-use-the-rest-api-instead)

Backwards compatibility. In theory, this library should be compatible with WP 4.1+.
