Extract from the linked example:

   HTTPClient http;    //Declare object of class HTTPClient

http.begin("http://192.168.1.88:8085/hello");      //Specify request destination
  http.addHeader("Content-Type", "text/plain");  //Specify content-type header

int httpCode = http.POST("Message from ESP8266");  //Send the request
  String payload = http.getString();                  //Get the response payload

Serial.println(httpCode);  //Print HTTP return code
  Serial.println(payload);    //Print request response payload

http.end();  //Close connection






Change:

http.begin("http://192.168.1.88:8085/hello");      //Specify request destination




to match your environment say:

http.begin("http://myserver.com/barCodeSave.php");





Change:

int httpCode = http.POST("Message from ESP8266");  //Send the request




to match your environment say:

int httpCode = http.POST("barcode=12345689&submit=Scan");





If that does not help, post the full code you are attempting to use.

Sorry for the late response. Thank you very much for you help, it works! I now have another problem. Is there any way I can make the esp8266 read some text from the website, and then store that text in a variable or print it in the serial monitor?
