I'm trying to use the placeholders (i.e., var1) with a chart.

The chart is based on a table (wpdatatable) that uses var1, but when I try a shortcode of [wpdatachart id=1 var1=22] the var1 doesn't work.  The var1 only uses the default in the table definition.

Is there something I'm not doing right?

Thanks - Dan 

I have an easy work-around for this you should check out.

This code could be modified in a number of ways.

1) I pass variables on the url, as in www.example.com/?var1=33&var2=123

2) I register the variables in my theme functions.php by adding this:

function add_query_vars_filter( $vars ){
  $vars[] = "var1";
  $vars[] = "var2";
  $vars[] = "var3";
  return $vars;
}
add_filter( 'query_vars', 'add_query_vars_filter' );

3) I add a plugin for shortcode as:

<?php
/*
Plugin Name: wpsetvars
Description: Custom vars in URL to Global vars
Version: 0.1
Author: Daniel Bare
Text Domain: wpsetvars
*/

function wpsetvars_func($params) {
global $wdtVar1, $wdtVar2, $wdtVar3;
if (get_query_var(var1')) {
$var1 = get_query_var('var1'); // get var1 from url line
//*** $params['var1']  -- could scrape from shortcode instead
$wdtVar1 = $var1;
}
if (get_query_var('var2')) {
$var2 = get_query_var('var2'); 
//*** $params['var2']
set_query_var('var2', $var2);
$wdtVar2 = $var2;
}
if (get_query_var('var3')) {
$var3 = get_query_var('var3'); 
//*** $params['var3'] 
$wdtVar3 = $var3;
}
return;
}

add_shortcode( 'wpsetvars', 'wpsetvars_func' );

?>

4) Activate Shortcode wpsetvars

5) in page - note - wpdatachart is based on a table that uses var1 

[wpsetvars][wpdatachart id=1]

6) use url www.example.com/?var1=3  

depending on what is var1 in in the url, the chart changes

done.

-------------

I suspect this would be easy to implement into the wpdatacharts, as it's so easy to do this.

I haven't tested this with wpdatatables, but it might work as well - to put the vars on the URL as well.

Hi,

I am currently using wpDataTables with placeholders to retrieve json data from my backend WebService. I found this feature is easy to use and flexible and this is one of the reason we decided to buy and use your product.

However, I found that I cannot use this placeholders when creating wpDataChart and I am very disappointed when I see your reply that using placeholders with charts are currently not supported.

When will this feature be added? Or do you have any workaround recommended?
