我当前正在使用GravityWP Count plugin 用于数字字段上的输入总计。为此，我还需要通过一个短代码减去总数。我联系了插件作者，他友好地回应了我，但我确信还有其他事情要做。

if (class_exists("GFForms")) {

 function gravitywp_count_func( $atts, $content = null ) {

add_shortcode( \'gravitywp_count\', \'gravitywp_count_func\' );

}

Shortcode:

Budget Total: $[gravitywp_count formid="8" sub_number="250000" 
number_field="37" filter_field="29" filter_value="Budget"  thousands_sep=","]

add_number shortcode:

Budget Total: $[gravitywp_count formid="8" add_number="-250000" 
number_field="37" filter_field="29" filter_value="Budget" thousands_sep=","]

Note: 该插件允许您使用add\\u number短代码，在减法数前面加一个-（减号），但返回一个负数。上面的短代码返回的是-245000，而不是245000。
