I am a newbie in a flutter. Can someone show me how to upload an image to my MySQL? I can’t find any solution in the past weeks.
My Code:
import 'dart:io';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:http/http.dart' as HTTP;
import 'package:image_picker/image_picker.dart';
import 'package:phpfood/OwnerPage.dart';
import 'globals.dart' as globals;
import 'dart:async';
class AddProduct extends StatefulWidget {
@override
_AddProductState createState() => _AddProductState();
}
class _AddProductState extends State<AddProduct> {
TextEditingController controllerName = new TextEditingController();
TextEditingController controllerPrice = new TextEditingController();
TextEditingController controllerType = new TextEditingController();
File _image;
Future getImageGallery() async{
// ignore: deprecated_member_use
var imageFile = await ImagePicker.pickImage(source: ImageSource.gallery);
setState(() {
_image = imageFile;
});
}
Future getImageCamera() async{
// ignore: deprecated_member_use
var imageFile = await ImagePicker.pickImage(source: ImageSource.camera);
setState(() {
_image = imageFile;
});
}
Future addProduct() async{
var url = 'http://10.0.2.2/foodsystem/addproduct.php';
//String base64Image = base64Encode(_image.readAsBytesSync());
//String fileName = _image.path.split("/").last;
http.post(url, body: {
"productname": controllerName.text,
"productprice": controllerPrice.text,
"producttype": controllerType.text,
"product_owner": globals.restaurantId,
//"image": base64Image,
//"imageName": fileName,
"image": _image.path,
//"image": _image.path.split('/').last,
});
}
/* Future addProduct(File imageFile) async{
// ignore: deprecated_member_use
var stream= new http.ByteStream(DelegatingStream.typed(imageFile.openRead()));
var length= await imageFile.length();
var uri = Uri.parse("http://10.0.2.2/foodsystem/uploadg.php");
var request = new http.MultipartRequest("POST", uri);
var multipartFile = new http.MultipartFile("image", stream, length, filename: basename(imageFile.path));
request.files.add(multipartFile);
request.fields['productname'] = controllerName.text;
request.fields['productprice'] = controllerPrice.text;
request.fields['producttype'] = controllerType.text;
request.fields['product_owner'] = globals.userId;
var respond = await request.send();
if(respond.statusCode==200){
print("Image Uploaded");
}else{
print("Upload Failed");
}

$producttype = $_POST['producttype'];
$image = $_POST['image'];
//$realImage = base64_decode($image);
$connect->query("INSERT INTO product (product_name, product_price, product_type, product_owner, image) VALUES ('".$productname."','".$productprice."','".$producttype."','".$product_owner."','".$image."')")
?>
MySQL database:
It only uploaded my image path to the database. Please help me. I have understood that “image”: _image.path, this code is the result why my database is saving the image path instead of a photo. I am already trying to search using the path location and save the image to the htdoc file but does not work when I am uploading it. The image is nowhere can be found in the htdoc. please help me.

Check out answers to How to upload an image in Flutter? for more on uploading files from flutter. You will want to use a MultipartRequest from http library.
A google search should also show you how to save the file to MySQL, probably as a blob. It’s a whole topic on its own, you might end up saving the files to the filesystem and storing paths in the database.
