Hai,
I faced the scenario wand to pass array value in postButton, It is possible, kindly guide me.
Thanks.
Not a cake example, but will point you in the right direction
array in post
https://book.cakephp.org/3.0/en/views/helpers/form.html#creating-post-buttons
there is 'data' option in there where you can set what additional data you want to send.
hidden fields in form also can help
