Create JSON out of JSON: Use it for a liveticker with “Auto Refresh API Ajax”

Challenge: Display the data from https://waterservices.usgs.gov/nwis/iv/?format=json&sites=01407600&parameterCd=72279&siteStatus=active

Local JSON stored at http://api.json-content-importer.com/extra/json/waterservices.usgs.gov.json

Simply displaying data is easy – create a Plugin template with the above URL and this Twigcode (Shortcode: [jsoncontentimporterpro nameoftemplate=NAME_OF_TEMPLATE])

Location:  {{value.timeSeries.0.sourceInfo.siteName}}<br>
Date: {{value.timeSeries.0.values.0.value.0.dateTime | date("Y-m-d",   "America/New_York") }} <br>
Time: {{value.timeSeries.0.values.0.value.0.dateTime | date("H:i",  "America/New_York") }}<br>
Water Level: {{value.timeSeries.0.values.0.value.0.value}}

In Action:

Location: Shrewsbury River at Sea Bright NJ
Date: 2022-06-29
Time: 21:24
Water Level: 1.81

Display this data with the “Auto Refresh API Ajax” Plugin- Way 1:

  • Install the Plugin
  • Create a HTML-Div like <div id="araatest">load data</div>
  • Go to the “Auto Refresh AA” menu and insert this:
  • URL: See above
  • What: value.timeSeries.0.values.0.value.0.value
  • Where: div[id="araatest"]

Display this data with the “Auto Refresh API Ajax” Plugin- Way 2:

Create a new JSON-Feed with the JCI-PRO-Plugin by adding a new plugin-template:

  • Name: waterservices-json
  • URL: https://waterservices.usgs.gov/nwis/iv/?format=json&sites=01407600&parameterCd=72279&siteStatus=active
  • twig-template:
{"time": "{{"now" | date("d.m.Y, H:i:s") }}", "data": "Location:  {{value.timeSeries.0.sourceInfo.siteName}}, Date: {{value.timeSeries.0.values.0.value.0.dateTime | date("Y-m-d",   "America/New_York") }}, Time: {{value.timeSeries.0.values.0.value.0.dateTime | date("H:i:s",  "America/New_York") }}, Water Level: {{value.timeSeries.0.values.0.value.0.value}}"}

Shortcode:

[jsoncontentimporterpro nameoftemplate="waterservices-json"]

This page with this Shortcode should be something like this:
http://api.json-content-importer.com/json-waterservices-usgs-gov/
Adding “?show=oc” removes the template and gives pure JSON:
http://api.json-content-importer.com/json-waterservices-usgs-gov/?show=oc

This JSON we can use in “Auto Refresh API Ajax”:

Example in Action:
load data

PRO: Plot JSON-data – WordPress Charts Plugin

Together with the Plugin “WordPress Charts” the PRO version of the JSON Content Importer can plot data in many ways. Unfortunately this plugin isn’t availiable in the WP-Repository any more.

Example: https://api.wordpress.org/stats/plugin/1.0/downloads.php?slug=json-content-importer&limit=51 gives us the latest 50 numbers of the downloads of the free JCI plugin. The challenge is to display that data like this:

Downloads of the free JSON Content Importer Plugin: Daily statistic of the last 50 days

For that we have to do this:

Name of template: wordpress-stat-plot
Install: WordPress Charts
Create a new JCI-pro-template with:

URL: https://api.wordpress.org/stats/plugin/1.0/downloads.php?slug=json-content-importer&limit=51

twig-template:

<a href="https://wordpress.org/plugins/json-content-importer/" target="_blank">Downloads of the free JSON Content Importer Plugin:</a> <a href="https://api.wordpress.org/stats/plugin/1.0/downloads.php?slug=json-content-importer&limit=51" target="_blank">Daily statistic of the last 50 days</a><br>{%set no = 0 %}
{% for dat,nodl in _parent %}{%set no = (_parent | length)-1 %}{% endfor %}

Save that template and use it on a page with the above shortcode

That’s it…

PRO: JCI-Template urlparam4twig

You can define a urlparam4twig-list like “one#two” via the shortcode “urlparam4twig ” or (preferrably) the JCI-plugin-template.

This gives you a flexible way to put a dynamic URL together for the API-call.

Create a template with the following settings. Save this template andput the shortcode on a page:

Click here and see the change in the following paragraph. You might change the values for the parameters.
In the back the twig code in the URL is executed and the values for “one” and “two” are used.

this is a template: <br>
time: {{ "now"|date("m.d.Y") }}<br>
urlparam "one": {{urlparam.one | e}}<br>
urlparam "two": {{urlparam.two | e}}

URL:

http://api.json-content-importer.com/extra/json/1.json?t={{ "now"|date("mdY") }}&a={{urlparam.one}}&b={{urlparam.two}}

urlparam4twig: one#two

In Action:

this is a template:

PRO: Openweather Forecast – search location, show weather

Challenge:
Show current and forecast weather data via
https://api.openweathermap.org/data/2.5/onecall?lat={{lat}}&lon={{lon}}&exclude={part}&appid=….
for a searchable location.

Solution:
Use the above API for the weather at a location defined by lat and lon. Also use the openweather-geocoding API to transform a locationname into lat & lon.

In Action:


Augsburg (DE , Bavaria ) show on map | show weather
Augsburg (DE , Schleswig-Holstein ) show on map | show weather
Augsburg (US , Illinois ) show on map | show weather
Augsburg (US , Arkansas ) show on map | show weather
Augsburg (GY , Mahaica-Berbice ) show on map | show weather

See how this is done with a JCI-Shortcode:

[jsoncontentimporterpro nameoftemplate="openweather-forecast"]

With this JCI-template:

  • urlparam4twig: su
  • URL:
{% set su = "augsburg" %}{% if urlparam.su %}{% set su = urlparam.su %}{% endif %}
http://api.openweathermap.org/geo/1.0/direct?q={{su}}&limit=10&appid=...

        {% endif %})
        <a href="https://www.google.com/maps/place//@{{l.lat}},{{l.lon}},14z" target="_blank">show on map</a>

    {% endif %}
{% endfor %}

PRO: API Zippopotamus, Shortcode-Parameter httpstatuscodemustbe200

The API http://zippopotam.us/ gives Citynames and Coorindates to a Zipcode. The JCI-PRO-Plugin can use that for a “Zipcode to City-Search”.

This done this way:



Examples: Houston, US, TX | Munich, DE, Germany

1 .JCI-Shortcode:

httpstatuscodemustbe200=no tells the plugin to accept also non-ok-API-answers

[jsoncontentimporterpro nameoftemplate="zip" httpstatuscodemustbe200=no]

2. JCI template:

  • url:
http://api.zippopotam.us/{% if urlparam.co %}{{urlparam.co}}{% else %}US{% endif %}/{% if urlparam.zip %}{{urlparam.zip}}{% else %}80636{% endif %}
  • urlparam4twig: zip#co

PRO: JSON meets JCI and jQuery for a facet-search

Selecting a hotel for oyur holiday depends on options like location and price. With a facet-search you select several locations out of the all available and define a range for the price. Then the matcihing hotels should be displayed.

This can be done with the JCI-PRO-Plugin which grabs the JSON-data, builds a facet and shows the selected data. See here for an example.

To build that you need a data-source (JSON-API), the JCI-PRO-Plugin, jQuery-Libraries (maybe part of your WordPress-template or loadable via JCI) and twig-Software für the facet and the results.

See here how this can be done.

PRO: Pagination by twig – several feeds, many pages

This page demonstrates how you can paginate data. The data comes in a several feeds (see here for data in one feeds)
