so i revamped the code to get better switching parameters ... and actually, the code to push to the server didn't work at alll ,,, 

i tried it again and nothing happened 

i never had that much of obstacles lol  i even made it live .... 

here is the functonal part of my code that im struggling to make it function when i push the physical button ,,,, that changes the status of the webserver code and the data it get sent back to my ESP

http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8&state= 1

 

u can see the results at : 

http://zeint.net/IOT/esp-outputs.php

this is the front end 

😫

anyways i added this ... 

const char* Pushserver = "http://zeint.net/IOT/esp-outputs-action.php";

and these ... 

void relayOnOff(int relay){

switch(relay){
case 1:
if(toggleState_1 == 0){
digitalWrite(RelayPin1, LOW); // turn on relay 1
toggleState_1 = 1;
Serial.println("Device1 ON");
}


else{
digitalWrite(RelayPin1, HIGH); // turn off relay 1
toggleState_1 = 0;
Serial.println("Device1 OFF");

HTTPClient http;
http.begin(Pushserver);
http.addHeader("Content-Type", "application/json");
String httpRequestData = "{\"action\":\"output_update\",\"id\":\"8\",\"state\":\"1\"}";///// this is to turn it on ,,, when i toggle the physical button
// String httpRequestData = "{\"action\":\"output_update\",\"id\":\"8\",\"state\":\"0\"}";///// this is to turn it off
Serial.print("httpRequestData: ");
Serial.println(httpRequestData);
int httpResponseCode = http.POST(httpRequestData);
if (httpResponseCode>0) {
Serial.print("HTTP Response code: ");
Serial.println(httpResponseCode);
}
else {
Serial.print("Error code: ");
Serial.println(httpResponseCode);
}
delay(1000);
break;
}
default : break;
}
}

since when u have this forum

Ehm, I'm using this forum for about a year or maybe 2 years now. I used a different forum before that.

Posted by: @murad

http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8&state= 1

I see there is a space before the "1" - is that accidental (there should not be a space there).
When using the link without a space, I see the last switch change (1=on, 0=off) correctly.

http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8&state=1

http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8&state=0

I'm not sure what is going wrong .. seems to work, right?

I think that accorded due to coloring i colored it in ur forum but when i push the actual button and the last script run it does nothing at all

The link is the GET format, where as your code is using the POST format.

Maybe you have to start over, try this code.
It only sets the switch to ON every 10 seconds, up to you to add the relay code mlater, once this works,
Test is with state=0 as well - to make sure it works, before adding the relay functions in it.

This is code from the link I previous gave you (paragraph called "Code ESP8266 HTTP GET with Arduino IDE"), just slightly adjust for the links and parameters you gave me in your previous post.

#include < ESP8266WiFi.h >
#include < ESP8266HTTPClient.h >
#include < WiFiClient.h >

const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";

//Your Domain name with URL path or IP address with path
String serverName = "http://zeint.net/IOT/esp-outputs-action.php";

// the following variables are unsigned longs because the time, measured in
// milliseconds, will quickly become a bigger number than can be stored in an int.
unsigned long lastTime = 0;
// Timer set to 10 minutes (600000)
//unsigned long timerDelay = 600000;
// Set timer to 5 seconds (5000)
unsigned long timerDelay = 5000;

void setup() {
  Serial.begin(115200); 

  WiFi.begin(ssid, password);
  Serial.println("Connecting");
  while(WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to WiFi network with IP Address: ");
  Serial.println(WiFi.localIP());
 
  Serial.println("Timer set to 5 seconds (timerDelay variable), it will take 5 seconds before publishing the first reading.");
}

void loop() {
  //Send an HTTP POST request every 10 minutes
  if ((millis() - lastTime) > timerDelay) {
    //Check WiFi connection status
    if(WiFi.status()== WL_CONNECTED){
      HTTPClient http;

      String serverPath = serverName + "action=output_update&id=8&state=1";
      
      // Your Domain name with URL path or IP address with path
      http.begin(serverPath.c_str());
      
      // Send HTTP GET request
      int httpResponseCode = http.GET();
      
      if (httpResponseCode>0) {
        Serial.print("HTTP Response code: ");
        Serial.println(httpResponseCode);
        String payload = http.getString();
        Serial.println(payload);
      }
      else {
        Serial.print("Error code: ");
        Serial.println(httpResponseCode);
      }
      // Free resources
      http.end();
    }
    else {
      Serial.println("WiFi Disconnected");
    }
    lastTime = millis();
  }
}

I only modified the red lines.

 

May I ask what operating system and browser you're using?
I'm not experiencing any of the issues you seem to be running into in this forum.

im using windows 10 and google chrome upated .... 

18:16:33.992 -> Connected to WiFi network with IP Address: 192.168.1.24
18:16:33.992 -> Timer set to 5 seconds (timerDelay variable), it will take 5 seconds before publishing the first reading.
18:16:34.742 -> HTTP Response code: 404
18:16:34.742 -> <html><head><title>Error 404 - Not Found</title><head><body><h1>Error 404 - Not Found</h1><p>The document you are looking for may have been removed or re-named. Please contact the web site owner for further assistance.</p></body></html>
18:16:40.183 -> HTTP Response code: 404

OHHHHHH

i messed up with the code and it worked like this ,,,, 

now im gonna try to implement it in my code :D 

ty a lot buddy 

#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <WiFiClient.h>
#include <Arduino_JSON.h>

#include <ESP8266WiFiMulti.h>
ESP8266WiFiMulti WiFiMulti;
const char* ssid = "MoKa";
const char* password = "mokamoka";

//Your Domain name with URL path or IP address with path
String serverName = "http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8";

// the following variables are unsigned longs because the time, measured in
// milliseconds, will quickly become a bigger number than can be stored in an int.
unsigned long lastTime = 0;
// Timer set to 10 minutes (600000)
//unsigned long timerDelay = 600000;
// Set timer to 5 seconds (5000)
unsigned long timerDelay = 5000;

void setup() {
Serial.begin(115200);

WiFi.begin(ssid, password);
Serial.println("Connecting");
while(WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.print("Connected to WiFi network with IP Address: ");
Serial.println(WiFi.localIP());

Serial.println("Timer set to 5 seconds (timerDelay variable), it will take 5 seconds before publishing the first reading.");
}

void loop() {
//Send an HTTP POST request every 10 minutes
if ((millis() - lastTime) > timerDelay) {
//Check WiFi connection status
if(WiFi.status()== WL_CONNECTED){
HTTPClient http;

String serverPath = serverName + "&state=1";

// Your Domain name with URL path or IP address with path
http.begin(serverPath.c_str());

// Send HTTP GET request
int httpResponseCode = http.GET();

if (httpResponseCode>0) {
Serial.print("HTTP Response code: ");
Serial.println(httpResponseCode);
String payload = http.getString();
Serial.println(payload);
}
else {
Serial.print("Error code: ");
Serial.println(httpResponseCode);
}
// Free resources
http.end();
}
else {
Serial.println("WiFi Disconnected");
}
lastTime = millis();
}
}

for some reason, i didn't allow me to use this method unless its in the main loop .... its about the "+" thingy and i worked it around using ur help

like this ,,,,  😊 


// Your IP address or domain name with URL path
const char* serverName = "http://zeint.net/IOT/esp-outputs-action.php?action=outputs_state&board=3";
////////////// Obstacle code//////////////
String Pushon = "http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8&state=1";
String Pushoff = "http://zeint.net/IOT/esp-outputs-action.php?action=output_update&id=8&state=0";
////////////// Obstacle code//////////////

http.begin(Pushon.c_str());


http.begin(Pushoff.c_str());

void loop(){
buttons();
http();
}

it didnt accept this code .... so i had to work around ,,  it is working finally i wish i can share some stuff here ,,,  each time i paste long ,,, it dissapears 

String serverPath = serverName + "&state=1";

Hi Murad,

well, I'm happy to see we're making progress 😊 
Excellent!

If you have a very long code, then please consider attaching the INO file, instead of pasting the code here.
Code can trigger a security error (a false positive) - at least that is my best guess why it keeps failing.
I couldn't find anything in the firewall log, but then again, the log is huge and quite cryptic at times.

It is a little weird that the "+" didn't work.
The official Arduino documentation states this should work. 🤔

Does it give an error message?
If not, try adding this:

Serial.println(serverPath);

After this line:

String serverPath = serverName + "&state=1";

so we can see what happens to the string.

@hans

it doesn't allow u to compile and upload at all 

C:\Users\moka\Desktop\Arduino DONE projects\=[[Personal cloud ]]=\touchless_PHP_webserver_send_and_get\touchless_PHP_webserver_send_and_get.ino: In function 'void relayOnOff(int)':
touchless_PHP_webserver_send_and_get:61:37: error: invalid operands of types 'const char*' and 'const char [9]' to binary 'operator+'
String serverPath = serverName + "&state=1";
^
exit status 1
invalid operands of types 'const char*' and 'const char [9]' to binary 'operator+'

i think it should be in the main loop to work ,,, the void loop anyways i attached the file ,,, thats how its finally done :D
