Retrieve data from portal form

[Herobyte]

Hi!
I need retrieve data from the form, example the Blynk_Server1 and put it in a variable, is possible?

`#if USE_DYNAMIC_PARAMETERS

#define MAX_BLYNK_SERVER_LEN 34
#define MAX_BLYNK_TOKEN_LEN 34

char Blynk_Server1 [MAX_BLYNK_SERVER_LEN + 1] = "account.duckdns.org";
char Blynk_Token1 [MAX_BLYNK_TOKEN_LEN + 1] = "token1";

char Blynk_Server2 [MAX_BLYNK_SERVER_LEN + 1] = "account.ddns.net";
char Blynk_Token2 [MAX_BLYNK_TOKEN_LEN + 1] = "token2";

#define MAX_BLYNK_PORT_LEN 6
char Blynk_Port [MAX_BLYNK_PORT_LEN + 1] = "8080";

#define MAX_MQTT_SERVER_LEN 34
char MQTT_Server [MAX_MQTT_SERVER_LEN + 1] = "mqtt.duckdns.org";

MenuItem myMenuItems [] =
{
{ "sv1", "Blynk Server1", Blynk_Server1, MAX_BLYNK_SERVER_LEN },
{ "tk1", "Token1", Blynk_Token1, MAX_BLYNK_TOKEN_LEN },
{ "sv2", "Blynk Server2", Blynk_Server2, MAX_BLYNK_SERVER_LEN },
{ "tk2", "Token2", Blynk_Token2, MAX_BLYNK_TOKEN_LEN },
{ "prt", "Port", Blynk_Port, MAX_BLYNK_PORT_LEN },
{ "mqt", "MQTT Server", MQTT_Server, MAX_MQTT_SERVER_LEN },
};`

This is the code, if I need retrieve the Blynk_Server1 put in the form and make this in variable, how make?
Or make another field and retrieve the data

Thanks

Have a look at

WiFiManager_NINA_Lite/examples/SAMD_WiFiNINA/SAMD_WiFiNINA.ino

Lines 101 to 111 in cdb027a

	void displayCredentials()
	{
	Serial.println(F("\nYour stored Credentials :"));
	for (uint16_t i = 0; i < NUM_MENU_ITEMS; i++)
	{
	Serial.print(myMenuItems[i].displayName);
	Serial.print(F(" = "));
	Serial.println(myMenuItems[i].pdata);
	}
	}

then you'll see, for example Blynk_Server1 is index 0 in the myMenuItems, then you can use the null-terminated string at

myMenuItems[0].pdata

and so on

You have to read a little bit more about pointer, etc.

Just a hint without explanation. Try, for example,

char *  Blynk_Server1 = myMenuItems[0].pdata;

then use it normally, such as

Serial.println(Blynk_Server1);

Sorry, but i not are espert in arduino programming..

I use a telegram library and I have this:

UniversalTelegramBot bot(BOT_TOKEN, client);
In this moment the BOT_TOKEN is picked up from a #define (#define BOT_TOKEN "TOKEN")

How picked up the Token from form portal?.. Ex: from Blynk_Server1 field ?

Thanks

Sorry I don't have time to help everybody here. I'd rather spend time to help many mode people with libraries than devoting time to help just one person.

If not OK, I suggest you post for help on Arduino, Telegram, etc. Forum. Remember to post full code or your request will be ignored.

Good Luck,

I saw you posted something on Arduino Forum, and that's a good sign that you are not passive and waiting only.

So the simple solution can be

char *myBOT_TOKEN =  myMenuItems[0].pdata;

UniversalTelegramBot bot(myBOT_TOKEN, client);

Thank you, you save me life :D
