New Field in Form

[Fabio Doebber]

I want to add these fields to the host form, but this error.
I edited the hosts.php and configuration.host.edit.php files

[Fabio Doebber]

I have modified hosts.php and now the error is another one

[Fabio Doebber]

• Undefined index: host_username [ in hosts.php:924]
  
  this is the modified code

I think that the part that you modified yourself is incorrect or the change is insufficient.
If you can not solve it yourself, I recommend not to customize, but to use the values in the existing inventory for another purpose.

resolved, it was necessary to change a file
