Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/463

I am thankful to @tzapu for giving this tremendous work. I want take some more parameters other than SSID and password from AutoConnectAP captive page. After selecting Configure Wifi if I want to add some more parameters, can anybody help me out there? I am novice programmer in HTML and C++. So requesting you to give detailed explanation

I did that with this project : https://github.com/reseauducommun/cociclo/tree/master/cociclo_transpiksel_eastern_bloc/software/cociclo_transpiksel_eastern_bloc

The first file in that directory has an example of latitude, longitude and userid added to the ssid + password.

Good luck ++

Hi, sorry about my english...
I have a problem, I added a new field in addition to pass and ssid. I am woriking with thinspeak to monitoring temperature and humity.

With de APIkey I dont have any problem, but if I want to put the channel number too, its not possible because de compilator says "invalid conversion from 'char' to 'long unsigned int' [-fpermissive*]"

This is te code I am using:
