1) Identify the json URL, and look at it using this tool: http://jsonviewer.stack.hu/ (or, if you know the json well, identify what you want to import.
2) Download jsonpath php file here: http://jsonpath.googlecode.com/files/jsonpath-0.8.1.php and place inside sites/all/modules/feeds_jsonpath_parser
3) Create a new parser using feeds, with the jsonpath parser selected
4) Example json:
{
"tumblelog": {
"title": "Tumblr Blog",
..... (other global fields)
},
"posts": [
{
"id": "46252144726",
"url": "http://whatever.com",
"type": "regular",
"date": "Mon, 25 Mar 2013 10:45:38",
"regular-title": "Test Blog Entry",
"regular-body": "Body text goes here",
"tags": [
"tag1",
"tag2",
]
},
{
"id": 46249331035,
.... rest of postsOK, so now is where I'm getting unclear, and need help.
5) In the jsonpath parser settings page:admin/structure/feeds/rss_feed_importer/settings/FeedsJSONPathParser there are two elements, "Context" and "Title". In the Context field, if you want to map the variables in post, to fields in a blog content type, for example, you need to let jsonpath parser know where to start. So in this case, the context would be:
$.tumblelog.posts.*
You basically want to tell the parser where to start looking for data to import.
You then need to go to mapping before finishing this configuration
6) Mapping. This is where you indicate which data element in the json data you have maps to which field in your content type. Add a "jsonpath expression" and then each field you want to map. So you're mapping will look like
jsonpath_parser:0 : Title
jsonpath_parser:1 : Body
jsonpath_parser:2: Published Date
etc.
7) Go back to the JSONPath parser settings page, and add the expressions for each field you mapped. If you set your context correctly, you should be able to just use the field name in the source json.
