Getting Default Values from Shortcode Attributes

Hi,

I developed a form according to https://contactform7.com/getting-default-values-from-shortcode-attributes/, therefore I need send 2 parameter to form externally instead of one.

Documentation:

[email* destination-email default:shortcode_attr]

[contact-form-7 id=”123″ title=”Contact Form” destination-email=”[email protected]”]

I need to add new field ; Please, How do i do that ?

Ps. I can’t update my wordpress ‘s version to use dynamic text plugin.

Regards,
Jo?o
