Pods JSON API

DEPRECATION NOTICE This plugin is deprecated. It should continue to work with version 1 of the REST API, but is no longer supported. Pods 2.6 and later has support for the WordPress REST API version 2 included.

This is a plugin that implements the pods and pods-api routes for WP-API Version 1.

It provides access to various methods in the Pods and Pods API classes in the Pods Framework.

Using AJAX

  • Example code is being migrated to our code-library repository.

See https://github.com/pods-framework/pods-code-library/tree/master/example/misc/json-api/examples for examples using AJAX.

Passing Parameters To Methods

You can pass the same parameters to each method as you usually would in the methods $parameters array, when using the method via PHP, by appending variables to the URL.

Querying For Pods Items With GET Requests

For example, to do a Pods::find() query on the Pod 'soup' that was the equivalent of:

    $params = array(
       'where' => 't.is_spicy = 1',
       'limit' => '7',
    );
$pods = pods( 'soup', $params );

You would use the url encoded equivalent of soup/find?where=t.is_spicy%3D1&limit=7 by passing the values through urlencode().

You can convert a PHP array, designed to be passed to Pods::find() or another method, to an encoded string, by first passing it through a foreach loop and encoding the values. For example, to create a long query, without manually encoding URLs, you could do:

    $params = array(
        'where' => 'serves.meta_value = "four or more"',
        'limit' => '7',
        'orderby' => 't.post_title ASC'
    );

    $url = json_url( 'pods/soup?find=' );
    
    $url = http_build_query( $params );

The variable, $url now has the url to query the 'soup' Pod, using Pods::find() by the parameters set in the array.

In the above example, the method find is used to illustrate the point that all methods of the Pods and Pods_API class that are accessible via this plugin can be specified this way. It is not actually needed as find is the default method for GET requests, while add is the default method for PUT requests.

All that is actually needed to create a find request is:

    $params = array(
        'where' => 'serves.meta_value = "four or more"',
        'limit' => '7',
        'orderby' => 't.post_title ASC'
    );

    $url = json_url( 'pods/soup' );

    $url = add_query_arg( $params, $url );
Updating Items With Post Requests

By default POST requests, sent to a Pods class endpoint will default to save_item. This allows for creating new items or updating existing items. In this example, a custom field--"home planet"--in anexisting item--Pod name "jedi", post ID 9--is being updated:

    $data = array( 'home_planet' => 'Alderann' );
    $url = json_url( 'pods/jedi/9' );
    
    //This example uses the basic authentication plugin for authentication
    $headers    = array (
        'Authorization' => 'Basic ' . base64_encode( 'username' . ':' . 'password' ),
    );
 
    $response = wp_remote_post( $url, array (
                        'method' => 'POST',
						'headers'     => $headers,
                        'body' => json_encode( $data )
        )
    );
    
    //make sure response isn't an error
    if ( ! is_wp_error( $response )  ) {
    
        //show the updated post item
        var_dump( wp_remote_retrieve_body( $response ) );
    }

Using The update_rel Endpoint

*Added in version 0.2

This endpoint is designed to address an issue that can occur when using the add_pod or save_pod methods with bi-directional relationship fields.

When these types of fields are updated/ created via the API, at the time of field creation/edit the sister IDs--the ID of the field in related Pod--can not be set if the related field does not yet exist and therefore does not have an ID. In addition, if the configuration is being copied from a remote site, the field IDs will be diffrent.

This endpoint is designed to be used to correct these errors after all Pods and Pods Fields are created. The data passed to it should be a multi-dimensional array, with each field represented like this:

```
[pod_name_field_name] =>
    [from] =>
        [field_name] => 'field_name',
        [pod_name] => 'pod_name',
    [to] =>
         [field_name] => 'field_name',
         [pod_name] => 'pod_name',
```

Importing a Pods Migrate Package

*Added in version 0.2

The pods-components endpoint allows for running a Pods Package import via the API. It can be used to import Pods, Pods Templates, Pods Pages and Pods Helpers. It requires that the Pods Migrate Package component be active on the remote site.

You can pass the Pods Package data--which is already in JSON format--to the body of a POST request.

Activating & Deactivating Components

*Added in version 0.2 You may bulk activate and/ or deactivate components with a PUT request to the pods-packages endpoint. You may also activate and/ or deactivate components individually using the pods-components/activate/<component> endpoint, using a POST request to activate, or a DELETE request to deactivate.

The activate/deactivate methods return true, with a status of 201 if the option that stores active components was updated and false, with a status of 500, if it was not. You can get a list of all components and their activation status by making a GET request to the pods-component endpoint.

Get a list of all components and whether they are active or not:

        $url = json_url( 'pods-components' );

        //This example uses the basic authentication plugin for authentication
        $headers    = array (
            'Authorization' => 'Basic ' . base64_encode( 'admin' . ':' . 'password' ),
        );

        $response = wp_remote_post( $url, array (
                            'method'    => 'GET',
                            'headers'   => $headers,
            )
        );

Activate and/ or deactivate multiple components at once:

    $data = array(  'deactivate' => array( 'templates', 'table-storage' ), 'activate' => array( 'pages' ) );

	$url = json_url( 'pods-components?activate_components' );

    //This example uses the basic authentication plugin for authentication
    $headers    = array (
        'Authorization' => 'Basic ' . base64_encode( 'admin' . ':' . 'password' ),
    );


    $response = wp_remote_post( $url, array (
                        'method'    => 'PUT',
                        'headers'   => $headers,
						'body'      => json_encode( $data )
        )
    );

Activate one component:

    $url = json_url( 'pods-components/activate/table-storage' );

    //This example uses the basic authentication plugin for authentication
    $headers    = array (
        'Authorization' => 'Basic ' . base64_encode( 'admin' . ':' . 'password' ),
    );

    $response = wp_remote_post( $url, array (
                        'method'    => 'POST',
                        'headers'   => $headers,
        )
    );

Deactivate one component:

    $url = json_url( 'pods-components/activate/templates' );

    //This example uses the basic authentication plugin for authentication
    $headers    = array (
        'Authorization' => 'Basic ' . base64_encode( 'admin' . ':' . 'password' ),
    );

    $response = wp_remote_post( $url, array (
                        'method'    => 'DELETE',
                        'headers'   => $headers,
        )
    );
