JSON Content Importer

Plugin to import, cache and display a JSON-Feed / JSON-API: Connect your Wordpress to an API / Webservice and display live JSON-data.

Display live data from a JSON-feed / API on your wordpress-site!

This is the answer when you ask: Why Do I Need this Plugin on my Website?

JSON Content Importer - API- and Webservice-Connector - Powerful and Simple JSON-Import Plugin:

  • Use a template engine to display the data of an JSON-Feed.
  • Define the url of the JSON-Feed, a template for it and other options like number of displayed items, cachetime etc..
  • The template engine inserts the JSON-data in the template provided in the wordpress-shortcode inside a page - whereby some extras like urlencoding can be invoked.

How to start and help

Simple Example of wordpress-shortcode


  • url="http://...json"
  • numberofdisplayeditems="number: how many items of level 1 should be displayed? display all: leave empty or set -1"
  • urlgettimeout="number: who many seconds for loading url till timeout?"
  • basenode="starting point of datasets, the base-node in the JSON-Feed where the data is"
  • oneofthesewordsmustbein="default empty, if not empty keywords spearated by ','. At least one of these keywords must be in the created text (here: text=code without html-tags)"
  • oneofthesewordsmustbeindepth="default: 1, number: where in the JSON-tree oneofthesewordsmustbein must be?"


Any HTML-Code plus "basenode"-datafields wrapped in "{}" {subloop:"basenode_subloop":"number of subloop-datasets to be displayed"} Any HTML-Code plus "basenode_subloop"-datafields wrapped in "{}". If JSON-data is HTML add "html" flag like "{fieldname:html}" {/subloop:"basenode_subloop"}


  • templates like "{subloop-array:AAAA:10}{text}{subloop:AAAA.image:10}{id}{/subloop:AAAA.image}{/subloop-array:AAAA}" are possible: one is the recursive usage of "subloop-array" and "subloop". the other is "{subloop:AAAA.image:10}" where "AAAA.image" is the path to an object. This is fine for some JSON-data.

Some special add-ons for datafields

  • "{street:purejsondata}": Default-display of a datafield is NOT HTML, but HTML-Tags are converted : use this to use really the pure data from the JSON-Feed
  • "{street:html}": Default-display of a datafield is NOT HTML: "<" etc. are converted to "&amp,lt;". Add "html" to display the HTML-Code as Code.
  • "{street:htmlAndLinefeed2htmlLinefeed}": Same as "{street:html}" plus "\n"-Linefeeds are converted to HTML-Linebreak
  • "{street:ifNotEmptyAddRight:,}": If datafield "street" is not empty, add "," right of datafield-value. allowed chars are: "a-zA-Z0-9,;_-:<>/ "
  • "{street:html,ifNotEmptyAddRight:extratext}": you can combine "html" and "ifNotEmptyAdd..." like this
  • "{street:ifNotEmptyAdd:,}": same as "ifNotEmptyAddRight"
  • "{street:ifNotEmptyAddLeft:,}": If datafield "street" is not empty, add "," left of datafield-value. allowed chars are: "a-zA-Z0-9,;_-:<>/ "
  • "{locationname:urlencode}": Insert the php-urlencoded value of the datafield "locationname". Needed when building URLs
  • "{locationname:unique}": only display the first instance of a datafield. Needed when JSON delivers data more than once

JSON Content Importer PRO

This free version of "JSON Content Importer" can put together many JSON-Feeds and is flexible with it's template-engine. But sometimes you might need more:

  • using as Widget
  • application building by creating a searchform and connect it to a JSON-API in the background: pass GET-Variables to use a dynamic JSON-Feed-URL ("talk to API / webservice")
  • usage on multisite installations
  • store Templates independent of pages
  • more Shortcode-Parameters
  • executing Shortcodes inside a template and
  • more features...

If the free version comes to your limit, I'm looking forward that you COMPARE PRO and FREE of the JSON Content Importer.

  • minor bugfix: JSON-Structures like { "$a": "$b"} can be handled (before: "$" made problems)

  • "made in munich" added (see faq)


  • Bugfix: tags like "{aa/aa}" are ok (previous: error)
  • Display JSON-HTML-Data really as HTML. Default: JSON-HTML-Data is displayed not as HTML but as HTML-Text. New in this version: tag-sytax like "{tag:html}" or "{street:html,ifNotEmptyAddRight:extratext}" allows real HTML-display.
  • New parameter in "[jsoncontentimporter]"-shortcode: set http-timeout "urlgettimeout". default is 5 seconds (ueful if source-website of JSON is slow)
  • Logo of plugin: Wordpress-Logo inserted
  • Update of screenshots




Completely rewritten template engine for even better JSON-handling:

  • "subloop-array": key should also be in the closing tag, e.g. "{subloop-array:KEY:10}{some_array_field}{/subloop-array:KEY}". The "subloop-array" without KEY in the closing tag is ok if there is only one "subloop-array" in the template. But if there are more than one "subloop-array" in the template insert the KEY in the closing tag! Then the template engine can identify the correct JSON-data.

  • "subloop": what is above for "subloop-array" is also for "subloop", e.g. "{subloop:KEY:10}{some_object_field}{/subloop:KEY}"

  • templates like "{subloop-array:AAAA:10}{text}{subloop:AAAA.image:10}{id}{/subloop:AAAA.image}{/subloop-array:AAAA}" are possible: one is the recursive usage of "subloop-array" and "subloop". the other is "{subloop:AAAA.image:10}" where "AAAA.image" is the path to an object.

  • JSON-data with multiple use of arrays can be handled by the template engine


  • Added Screenshots
  • Enhanced "subloop-array", new processing of pure string/numeric-array data (before: only string/numeric-data in an object)
  • Enhanced FAQs: Added Link to Website for better creating shortcode-markups




Enhanced the template engine for better JSON-handling.
