             Summary: ZeppelinContext Get-Form-Input-Data method
                 Key: ZEPPELIN-3383
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3383
             Project: Zeppelin
          Issue Type: New Feature
          Components: documentation, GUI
            Reporter: Sanjay Dasgupta


There have been requests for a method to enable programmatic access to form 
input data (e.g. 
[Zeppelin-425|https://issues.apache.org/jira/browse/ZEPPELIN-425]). It is 
proposed to augment ZeppelinContext with the following method to allow such 
access:

{{z.getFormInput("var-name")}}

The availability of _getFormInput()_ will also allow form inputs to be used 
globally across the notebook (also often requested, e.g. 
[Zeppelin-1680|https://issues.apache.org/jira/browse/ZEPPELIN-1680]) by 
creating a Z variable with the same name:

{{z.put("var-name", z.getFormInput("var-name"))}}
