I got this after I try to running my code on esp32

Notice: Undefined index: imageFile in C:xampphtdocsacc.php on line 23

My code on esp32

HTTPClient http;

http.begin("http://192.168.43.86/acc.php");  //Specify destination for HTTP request

http.addHeader("Content-Disposition", "form-data; name="imageFile"; filename="picture.jpg"rn");

http.addHeader("Content-type", "image/jpeg");



int httpResponseCode = http.POST(cam.getfb(), cam.getSize());





if (httpResponseCode > 0) {



  String response = http.getString();                       //Get the response to the request



  Serial.println(httpResponseCode);   //Print return code

  Serial.println(response);           //Print request answer



} else {



  Serial.print("Error on sending POST: ");

  Serial.println(httpResponseCode);



}



http.end();

I can send String by using this code but my code above don't work
(cam.getfb() return as uint8_t and cam.getSize() return as size_t)

  http.addHeader("Content-type", "application/x-www-form-urlencoded");

  int httpResponseCode = http.POST("word=" + Cword);

code in php

<?php

$uploadOk = 1;

if(1) {

    $check = getimagesize($_FILES["imageFile"]["tmp_name"]);

    if($check !== false) {

        echo "File is an image - " . $check["mime"] . ".";

        $uploadOk = 1;

    } else {

        $uploadOk = 0;

11/13/2018 I try to update my code

<?php
