Hi there mariacp04,
You can modify the values of any filter – including the cost filter – by using this hook:
tribe_events_filter_values
A minimal example would look a bit like this:
add_filter( 'tribe_events_filter_values', 'modify_cost_filter', 10, 2 );
function modify_cost_filter( $values, $filter_slug ) {
// We're only interested in the cost filter here
if ( 'cost' !== $slug ) return $values;
// Prepare your alternative costs according to your particular needs
$costs = array(
array( 'name' => '1-100', 'value' => '1-100' ),
array( 'name' => '101-1000', 'value' => '101-1000' )
);
// Replace the defaults with your new options
return $costs;
}
(You might add your custom code to your theme’s functions.php file or else a standalone plugin.) I hope that helps!
