 1 | # JSON Expand Plugin for CraftCMS
 2 | 
 3 | A simple Craft CMS twig extension that returns your object or array of objects as JSON
 4 | 
 5 | ## Usage
 6 | 
 7 | install the plugin and it will create a new twig filter and an action url
 8 | 
 9 | ### Twig Filter
10 | 
11 | you can use this in any template like so
12 | 
13 |     {% set events = craft.entries.section('events').find() %}
14 |     {{ events | json_expand | raw  }}
15 | 
16 | ### Action Url
17 | 
18 | you can also call up all the elements in a section directly by using the action url
19 | 
20 |     /actions/jsonExpand/sections/query?sectionId=4
21 | 
22 | where the sectionId the id of the section whose entries you want to grab.
23 | 
24 | Hope to add more filtering options to the action urls shortly.
25 | 
26 | ## TODO
27 | 
28 | * Add more filtering by action url
29 | * Add support for more fieldtypes
30 |
