How to pass a variables to wifiManager by Tapzu for esp 8266, i want to be able to pass mqtt id and password

Question

I am able to configure the esp8266 using the tapzu wifi manager, i would also like to send the mqtt server id and password from the wifi configure page so that the esp can connect to the mqtt server. I do not want to be flashing the esp every-time, any resources would be much appreciated. Thank you.

You can add custom parameters to WiFiManager by:

// id/name, placeholder/prompt, default, length
WiFiManagerParameter custom_mqtt_server("server", "mqtt server", mqtt_server, 40);
wifiManager.addParameter(&custom_mqtt_server);

And you can retrieve the values by

mqtt_server = custom_mqtt_server.getValue();
