It’s a bit of a hack, but you can make the info popup display whatever you like by creating a fake entity and setting it as the viewer’s selected entity. For example:

var entity = new Cesium.Entity('Title to put in the infobox');
entity.description = {
    getValue : function() {
        return 'HTML to display in the infobox';
    }
};
viewer.selectedEntity = entity;

Cesium – How to Improve InfoBox ?

Leave a reply

In order to run a script in the infobox, you have to enable scrips to run in the iframe. This is disabled by default for security reasons, in case you don’t know the source of the data populating the infobox.
You can enable scrips with this code:

var iframe = document.getElementsByClassName('cesium-infoBox-iframe')[0];
iframe.setAttribute('sandbox', 'allow-same-origin allow-scripts allow-popups allow-forms');

Also, to get the current value of an entity property, you can use .getValue(viewer.clock.currentTime);

How do I find ElasticSearch path to install plugins?

Leave a reply

This is for new ElasticSearch user.

If you have installed elastic search and unable to install plugins, here are the easy steps.

1. Type this command

$ curl "localhost:9200/_nodes/settings?pretty=true"

elasticsearch-plugin

Locate your home directory ( Look for Settings -> Path -> Home for value )
2. Go to Location (Example on the picture above)

 cd /opt/kibana/esvm/dev/branch-2.3" 

Install Plugin (Example plugin: mobz/elasticsearch-head)

 sudo bin/plugin install mobz/elasticsearch-head

If you are using old elasticSearch use "-install" instead of just install

I have ES 2.1.0 and the command is : sudo bin/plugin install mobz/elasticsearch-head  for me

How to test –

Open this URL

http://localhost:9200/_plugin/head/

If you see this, your plugin is working.
phpmind-elasticsearch-head-plugin

similarly, you can install other plugins –

sudo bin/plugin install https://github.com/AIsaac08/bigdesk/archive/master.zip

Command which is given in the site is not working on 29th of Nov 2015

How to access external data from Kibana Plugin?

phpmind-kibana-image

To make AJAX call from Kibana Visualization to external web service.

 $.ajax({
     type: "GET",
     url: 'http://localhost/es',
     headers: {'Content-Type':'application/x-www-form-urlencoded'},
     success: function(my_result) {
          console.log(my_result);
     },
     error: function() {
          alert("error1");
     },
});

There are two separate headers that are necessary here: access-control-allow-origin and access-control-allow-headers. You’re currently setting access-control-allow-origin but I don’t see anywhere you’re setting access-control-allow-headers.

How protect files using php and .htaccess ?

Leave a reply

phpmind-password-dialog

You can secure any file using this script.
It will not allow you to access without username and password.

1st step is to create .htaccess file in a folder which you want to protected.
2nd step is add index.php as shown in example. This will not work as it is but you can modify.

/*******************************************************/


.htaccess file

/********************************************************/

Options -Indexes 

RewriteEngine On

RewriteCond $0 !^(favicon\.ico|favicon\.png|media|robots\.txt|crossdomain\.xml|css|js)

RewriteRule .* index.php?file=$0 [QSA,L] # pass everything thru php
