Dynamically change which fields are seen

Here is the solution, for anyone using their own custom table of data and using that data to determine what fields should be displayed.

Add the following to your field definition. Does not matter if it is a group field or single.
'show_on_cb' => 'YourPrefix_set_field_data_attr',

then customized the call back to your particular conditions:

function YourPrefix_set_field_data_attr($field)
{
    $Fieldid          = $field->args( 'id' );
    $CMB2Fieldname    = $field->args( '_name' );
    $Prefix           = 'YourPrefix';
	
    if($Prefix == $Fieldid)            // Whole table Id, skip it
	  return 1;
	    
    $SearchPrefix      = 'YourPrefix' . '_'; 
    $pieces            = explode($SearchPrefix, $Fieldid);
    $pieces            = explode('_', $pieces[1]);
	$RowId             = $pieces[0];
	$CMB2Leader        = $SearchPrefix . $RowId . '_';
	$pieces            = explode($CMB2Leader, $Fieldid);
	$StandardFieldName = $pieces[1];     // This should match the fields table name
	
	// These are my conditions, use your own conditions.
	$current_user  = wp_get_current_user();
	$DatabaseData  = FindListing($current_user->user_email);
	if($DatabaseData[$RowId]['SubscriptionName'] == "YOUR DATABASE KEY")
	  {
      // Get the input fields
	  $input_fields       = GetTemplateFields(1);   // Table of fields
	  for($i=0; $i<sizeof($input_fields); $i++)
           {		  
	   $Field         = $input_fields[$i];    // CMB2 Field Name without prefix  
	   $FieldId       = $Field['id'];
           $bDisplayText  = $Field['textdisplay'];
           if($FieldId == $StandardFieldName && $bDisplayText == 0)
	     {
	      unset($DatabaseData);  
              return 0;               // Turn off the field
	     }
	    }
	 }    
   

unset($DatabaseData);
return 1;               // Display the field
}

Thank you for your help. Much appreciated. It works wonderfully, with no saving or refreshing..that is what I like about it. The only piece of code that “blinks” ironically, is the Jquery code to rename the rows. But I can live with that.

Thanks again.
