Hi i need to send my to web host and im getting error 403 forbidden error but i from the and its a public web host.
#include <ESP8266WiFi.h>

const char* ssid = "AdiWifi";

const char* host = "192.168.43.219";
#define DHTPIN 0
DHT dht(DHTPIN, DHT11);
#define LED D5 // Led in NodeMCU at pin GPIO16 (D0).
//float temp = 23;
//float humidity = 34;
void setup() {
Serial.begin(9600);
delay(10);
Serial.println();
Serial.println();
Serial.print("Connecting...");
Serial.println(ssid);
WiFi.begin(ssid, password);
while(WiFi.status() !=WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi Connected");
Serial.println("IP Address :");
Serial.println(WiFi.localIP());
}
void loop() {
float h = dht.readHumidity();
float t = dht.readTemperature();
if(h>60)

}

Serial.print("Connecting to");
Serial.println(host);

unsigned long timeout =millis();

}

This is the arduino code.
<?php
$temp =(float) $_GET['temp'];
$humidity = (float)$_GET['humidity'];
$servername = "localhost";
$username = "kaluthar";
$password = "*****";
$dbname = "temperature_humidity";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO temps (temp, humidity)
VALUES ('".$temp."', '".$humidity."')";
// use exec() because no results are returned
$conn->exec($sql);
echo "New record created successfully";
}
catch(PDOException $e)
{
echo $sql . "
" . $e->getMessage();
}
$conn = null;
?>
this is my php code. i have no idea why its getting me 403 error.
this is my serial monitor

And what is the output if you try to access http://192.168.43.219:8080 from your pc?
In your 'GET' header, you supply the entire URL.
So not this:
GET http://198.54.116.102/Nodemcu/save.php?temp=28.80&humidity=63.00 HTTP/1.1
but this:
GET /Nodemcu/save.php?temp=28.80&humidity=63.00 HTTP/1.1

Do not include the host, protocol, or port in the URL you request - you have already specified that when you opened the connection to that host on that port.
Including the host, protocol, and port in the URL is technically legal, but it is never done in practice, and many servers don't handle it properly. Heck, in my day job I ran into a bug that had been undiscovered for years until a customer's badly written script made a request including those, and found the issue.
BUT - in your case, what you're requesting isn't even legal, because further down your code appends "GET /" to the front of it, so you're doing something like:
GET /http://198.54.116.102/Nodemcu/save.php?temp=28.80&humidity=63.00
Which is just wrong (and the server is correctly refusing to serve the obviously invalid URL)
So you want something like:
String url = "Nodemcu/save.php?";
url += "temp=";
url += t;
url += "&humidity=";
url += h;
(well, String is evil and you should avoid using it like the plague in Arduino land, particularly the way you're doing it there, repeatedly appending to a String is how you bring out the bugs - but that's not the problem here, and it's less of a problem on an ESP8266 because of how much ram it has in general. Real programmers use c strings (null terminated fixed length character arrays), at least when programming embedded devices - it's good for the soul)

okay sir i will do like that thank you very much
If you react to the last post, don't use quote please. Even more, try to avoid quoting long posts.
