Concatenate many form fields and send them in one 3rd party field

Hi,

Thank you for this excellent plugin!

Using CF7 I can’t figure out how to configure this :

“I need to submit multiple values as…

By default, if more than one value appears in the post request for the same field/key, they will be joined by the ‘separator’ value like &post-values=a,b,c.
However, if you use [] as the separator it will instead create multiple keys like &post-values[]=a&post-values[]=b&….
Use [#] to retain the numerical index: &post-values[0]=a&post-values[1]=b&…
Use [%] to place the numerical index at desired location; specifically useful with nested fields via Xpost below (and issues #11 and #7).”

to concatenate 2 texts fields in one string 3rd party field.

Could please post a screenshot ?

Thanks and best regards

Bernard
