Is it possible to create Amcharts via wp API

Hi,

I’m trying to see if there is a way to interact with the amcharts plugin via the wp api and can not find anything in that regard through my searches.

Anyone have any insight on this?

Cheers,

Steven

Since WP API allows creating any post type, you can create charts as well.

However, you would need to reverse-engineer either plugin code or existing DB records, in order to know how to populate those posts.

I’m afraid we do not offer any specialized amCharts-specific API.

Thanks for the reply.

I’m looking through it now, and the only thing that I’m struggling with (so far) is the amcharts_nonce. Is that required? I’m not sure how I’ll be able to replicate that from an api perspective.

It looks like this may do the trick, but it’ll fail without a validated nonce.

{
   'post_type':'amchart',
   'amcharts_nonce':nonce,
   'resources':'resource list goes here',
   'html':'html content',
   'javascript':'javascript content',
   'slug':'slug-id',
}

nonce is used to prevent resubmission of forms. It should not be relevant if you are creating WP posts directly.

in setup.php
add
‘show_in_rest’ => true, to the args
update args:
'supports' => array( 'title' , 'html' , 'javascript' , 'slug' , 'resources' ),

You can override the route by specifying rest_base in args by the way.

I’m getting a 201 response with the payload above(minus nonce). but none of the values are populated in the draft chart/post.

Any thoughts on what I can do from here?
I’d love to write a full post on how to do this from start to finish.

I’ve tried _amcharts_resources type of nomenclature as well (this is the database postmeta naming convention) but nothing I’ve tried has actually populated the meta fields in the chart.

OK, i got this to work. 🙂

add the 2 items above in the top of setup.py

and at the bottom of setup.py add:

add_action("rest_api_init", function () {
    register_rest_field("amchart", "_amcharts_html",
        [
          "get_callback" => function ($post, $field_name, $request, $object_type) {
                return get_post_meta($post["id"], $field_name, true);
            },
            "update_callback" => function ($value, $post, $field_name, $request, $object_type) {
                return update_post_meta($post->ID, $field_name, $value);
            }
        ]);

register_rest_field("amchart", "_amcharts_javascript",
      [
        "get_callback" => function ($post, $field_name, $request, $object_type) {
          return get_post_meta($post["id"], $field_name, TRUE);
        },

        "update_callback" => function ($value, $post, $field_name, $request, $object_type) {
          return update_post_meta($post->ID, $field_name, $value);
        }
      ]);

    register_rest_field("amchart", "_amcharts_resources",
        [
          "get_callback" => function ($post, $field_name, $request, $object_type) {
                return get_post_meta($post["id"], $field_name, TRUE);
            },

            "update_callback" => function ($value, $post, $field_name, $request, $object_type) {
                return update_post_meta($post->ID, $field_name, $value);
            }
    ]);

    register_rest_field("amchart", "_amcharts_slug",
        [ "get_callback" => function ($post, $field_name, $request, $object_type) {
                return get_post_meta($post["id"], $field_name, TRUE);
        },

        "update_callback" => function ($value, $post, $field_name, $request, $object_type) {
                return update_post_meta($post->ID, $field_name, $value);
            }
        ]);
});

register_meta('amchart', '_amcharts_html', array(
  "type" => "string",
  "show_in_rest" => true,
  "object_subtype" => "amchart"

));
register_meta('amchart', '_amcharts_javascript', array(
  "type" => "string",
  "show_in_rest" => true,
  "object_subtype" => "amchart"
));
register_meta('amchart', '_amcharts_resources', array(
  "type" => "string",
  "show_in_rest" => true,
  "object_subtype" => "amchart"
));
register_meta('amchart', '_amcharts_slug', array(
  "type" => "string",
  "show_in_rest" => true,
  "object_subtype" => "amchart"
));

a working example is:

payload body:

 {
         'post_type': 'amchart',  //
         'title': 'title',
         'status': 'publish',
         '_amcharts_resources':'resource list goes here',
         '_amcharts_html':'html content',
         '_amcharts_javascript':'javascript content',
         '_amcharts_slug':'slug_testing'
}
