Publish multiple sets of Data

[transistor1990]

Please Help me to convert multiple data into one and publish it to mqtt.

i have these data:
Temperature: [0-120]
Pump: [0-100]
Heater: [0-100]
Status: [0 or 1]
the format to send must be [Temperature,Pump,Heater,Status]
the "[" and "]" must be included in the message.

will i have to create a variable to collect all data into one like

message= "[" + Temperature + "," + Pump ... "]"
wmm.client->publish(topic, String(message).c_str(), true);

thanks

I have managed to upload my code however an Error occurred on Serial Window.

Here is my Code:
`#include "secrets.h"
#include <WiFiMQTTManager.h>

// Button that will put device into Access Point mode to allow for re-entering WiFi and MQTT settings
#define RESET_BUTTON 0

WiFiMQTTManager wmm(RESET_BUTTON, AP_PASSWORD); // AP_PASSWORD is defined in the secrets.h file

void setup() {
Serial.begin(115200);
Serial.println(F("WiFiMQTTManager Basic Example"));
// set debug to true to get verbose logging
// wm.wm.setDebugOutput(true);
// most likely need to format FS but only on first use
// wmm.formatFS = true;
// optional - define the function that will subscribe to topics if needed
// wmm.subscribeTo = subscribeTo;
// required - allow WiFiMQTTManager to do it's setup
wmm.setup(SKETCH_NAME);
// optional - define a callback to handle incoming messages from MQTT
// wmm.client->setCallback(subscriptionCallback);

}

void loop() {
// required - allow WiFiMQTTManager to check for new MQTT messages,
// check for reset button push, and reconnect to MQTT if necessary
wmm.loop();

// optional - example of publishing to MQTT a sensor reading once a 1 minute
long now = millis();
if (now - wmm.lastMsg > 60000) {
wmm.lastMsg = now;
float temperature = 70; // read sensor here
float pump = 50;
float heater = 80;
float stat = 1;
String message = "[" + String(temperature) + "," + String(stat) + "," + String(heater) + "," + String(pump) + "]";
Serial.print("Temperature: ");
Serial.println(temperature);
char topic[100];
snprintf(topic, sizeof(topic), "%s%s%s", "sensor/", "d150", "/ctemperature");
wmm.client->publish(topic, String(message).c_str(), true);
}

}
`
