Problem: I would like to use a PHP variable in a shortcode attribute.

Solution: You can't use PHP variables directly in your shortcode attributes. Instead, you could create a custom shortcode that returns the value of that variable, and place that shortcode instead of the variable in your attribute.

$working_memap_id = 'some-post-slug';
 
add_shortcode( 'global_memap_id', 'global_memap_id_func');
function global_memap_id_func($atts)
{
  global $working_memap_id;
  return $working_memap_id;
}

[cred form form="properformname" post="[global_memap_id]"]

Register the name of the shortcode in Toolset > Settings > Frontend content > 3rd party shortcode arguments.
