The gravityflow_columns_inbox_table filter allows the columns to be modified for the inbox page.

Warning: only use this filter if you fully understand what you're doing, as it can interfere with the inbox filters. Different filters return different columns, so you need to make sure you return the right columns.


Example 1 Changes column headers for 'Submitter' and 'Step' on the Workflow Inbox page.

add_filter( 'gravityflow_columns_inbox_table', 'nc_gravityflow_columns_inbox_table', 10, 2 );
function nc_gravityflow_columns_inbox_table( $columns, $args ) {
   $columns['created_by'] = "New title for submitter column";
   $columns['workflow_step'] = "New column title";
   return $columns;

Note: If you want to customize the values that display within a column (such as if you were adding a new/custom column) you would want to also create a filter with gform_entries_field_value.


This code should be placed in the functions.php file of your active theme.
