Hello piklist friends,
I was wondering if anyone would know how to number the order of the drag and drop fields of an add_more group?
I would like to eventually be able to have citations below a post, which are sortable, and labeled by their order in the editor view.
piklist('field', array( 'type' => 'group' ,'label' => __('Sources') ,'description' => __('Any additional sources to cite') ,'field' => 'sources_group' ,'add_more' => true ,'fields' => array( array( 'type' => 'text' ,'field' => 'source_title' ,'label' => 'Source Title' ,'columns' => 12 ,'attributes' => array( 'class' => 'large-text' ) ) ,array( 'type' => 'text' ,'field' => 'source_text' ,'label' => 'Source Text' ,'columns' => 12 ,'attributes' => array( 'class' => 'large-text' ) ) ,array( 'type' => 'text' ,'field' => 'source_url' ,'label' => 'Source URL' ,'columns' => 12 ,'attributes' => array( 'class' => 'large-text' ), 'validate' => array( array( 'type' => 'url' ) ) ) ) )); -
Essentially I want to get some awareness in the data model of the user chosen sorting order of the add more fields which are draggable.
Perhaps the json would look something like this:
{ "sources_group": { "order": "0", "source_title": "Title of source", "source_text": "some text", "source_url": "http://www.somewhere.com" }, "order": "1", "source_title": "Title of source", "source_text": "more text", "source_url": "http://www.somewhereelse.com" } } -

Is there a way to expose this in the same array? I’m using this with the JSON API plugin

@rcantor– You can save the data in one array by setting a field for the entire group.
'type' => 'group' ,'label' => __('Sources') ,'field => 'my_sources'Now all data will be saved in the field,
my_sources, as an array.Does that help?

Hmmm, there appears to be an a and s key in the array, but it seems to not have anything to do with source order.
Here’s my piklist code:
piklist('field', array( 'type' => 'group' ,'label' => __('Sources') ,'description' => __('Any additional sources to cite') ,'field' => 'sources_group' ,'add_more' => true ,'fields' => array( array( 'type' => 'text' ,'field' => 'source_title' ,'label' => 'Source Title' ,'columns' => 12 ,'attributes' => array( 'class' => 'large-text' ) ) ,array( 'type' => 'text' ,'field' => 'source_text' ,'label' => 'Source Text' ,'columns' => 12 ,'attributes' => array( 'class' => 'large-text' ) ) ,array( 'type' => 'text' ,'field' => 'source_url' ,'label' => 'Source URL' ,'columns' => 12 ,'attributes' => array( 'class' => 'large-text' ), 'validate' => array( array( 'type' => 'url' ) ) ) ) ));and the JSON:
{ "status": "ok", "post": { "id": 31, "type": "post", "slug": "testing-a-cited-post", "url": "http://localhost:8888/2015/10/26/testing-a-cited-post/", "status": "publish", "title": "Testing a cited post", "title_plain": "Testing a cited post", "content": "<p>Body text</p>\n", "excerpt": "<p>Hello excerpt here</p>\n", "date": "2015-10-26 14:58:10", "modified": "2015-10-26 14:58:19", "categories": [ { "id": 2, "slug": "memos", "title": "Memos", "description": "", "parent": 0, "post_count": 2 } ], "tags": [], "author": { "id": 1, "slug": "admin", "name": "admin", "first_name": "", "last_name": "", "nickname": "admin", "url": "", "description": "" }, "comments": [], "attachments": [], "comment_count": 0, "comment_status": "open", "custom_fields": { "media_label": [ "" ], "author_name": [ "" ], "author_title": [ "" ], "author_twitter": [ "" ], "demo_add_more": [ "single" ], "sources_group": [ "a:3:{s:12:\"source_title\";a:2:{i:0;s:25:\"Title of source somewhere\";i:1;s:30:\"Title of Source somewhere else\";}s:11:\"source_text\";a:2:{i:0;s:9:\"more text\";i:1;s:9:\"some text\";}s:10:\"source_url\";a:2:{i:0;s:24:\"http://www.somewhere.com\";i:1;s:28:\"http://www.somewhereelse.com\";}}" ] } }, "previous_url": "http://localhost:8888/2015/10/14/another-post/" } -
WordPress stores this data in a serialized array. You can unserialize two ways:
1) Use the standard WordPress functionget_post_meta:
$sources_group = get_post_meta($post->ID, 'sources_group', true);2) Unserialize with the standard PHP function,
unserialize.Does that make sense?

That does, I was just hoping there was some way of adding an index to the data model… any suggestions?
I am now using the WP-API plugin and see that they come in the correct order, but I’d like to harden things a bit more by having an index if possible.

@rcantor– The json api has a filter, json_api_encode, that you can use to manipulate the data before the output.
Try this:
add_filter('json_api_encode', 'my_json_api_encode'); function my_json_api_encode($data) { // Are we on a single post if (is_single()) { // Get the sources_group field $sources_group = get_metadata('post', $data['post']->id, 'sources_group', true); if ($sources_group) { foreach ($sources_group as $index => &$group) { // Add the index to the objecdt $group['order'] = $index; } // Add updated object back to the json $data['post']->sources_group = $sources_group; } } return $data; }It should render like this:
"sources_group":[ { "source_title":"title 1" ,"source_text":"text 1" ,"source_url":"http:\/\/piklist.com" ,"order":0 } , { "source_title":"title 2" ,"source_text":"text 2" ,"source_url":"http:\/\/google.com" ,"order":1 } ]Let me know if that works for you.
