PHP upload from iOS using Alamofire

Problem is in your savePhotos function of PHP source. Also some extra code written in iOS code. I have removed extra code. Try once.

Here is the iOS code updated

Alamofire.upload(.POST, urlString, multipartFormData: {        multipartFormData in        if (firstPhoto != nil) {            if  let firstImageData = UIImagePNGRepresentation(firstImage!, 0.6) {                print("uploading image");                multipartFormData.appendBodyPart(data: firstImageData, name: "firstImage", fileName: "firstImage.png", mimeType: "image/png")            }        }        if (secondPhoto != nil) {            if  let secondImageData = UIImagePNGRepresentation(secondImage!, 0.6) {                print("uploading image");                multipartFormData.appendBodyPart(data: secondImageData, name: "secondImage", fileName: "secondImage.png", mimeType: "image/png")            }        }        if (thirdPhoto != nil) {            if  let thirdImageData = UIImagePNGRepresentation(thirdImage!, 0.6) {                print("uploading image");                multipartFormData.appendBodyPart(data: thirdImageData, name: "thirdImage", fileName: "thirdImage.png", mimeType: "image/png")            }        }        for (key, value) in parameters {            multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)        }        }, encodingCompletion: {            encodingResult in            switch encodingResult {            case .Success(let upload, _, _):                print("Запрос отправлен")                upload.responseJSON { response in                    print(response.request)  // original URL request                    print(response.response) // URL response                    print(response.data)     // server data                    print(response.result)   // result of response serialization                    if let JSON = response.result.value {                        print("JSON: \(JSON)")                    }                    completion(response.result.value)                }            case .Failure(let encodingError):                print(encodingError)                completion(nil)            }    })}

And here is the PHP code

function savePhotos($mysqli, $bookID) {    $basePath = '/home/thebakpa/resources/book_photos/'    if(!is_dir($basePath)) {        mkdir($basePath, 0777, true);    }    try {        $file1 = $_FILES['firstImage'];        if (is_uploaded_file($file1['tmp_name'])) {            $photoPath = $basePath.'photo1-'.$bookID.'.jpg';            if (move_uploaded_file($file1['tmp_name'], $photoPath)) {                $mysqli->query('UPDATE Book SET photo1='.$photoPath.' WHERE bookID='.$bookID.'');            }        }        $file2 = $_FILES['secondImage'];        if (is_uploaded_file($file2['tmp_name'])) {            $photoPath = $basePath.'photo2-'.$bookID.'.jpg';            if (move_uploaded_file($file2['tmp_name'], $photoPath)) {                $mysqli->query('UPDATE Book SET photo2='.$photoPath.' WHERE bookID='.$bookID.'');            }        }        $file3 = $_FILES['thirdImage'];        if (is_uploaded_file($file3['tmp_name'])) {            $photoPath = $basePath.'photo3-'.$bookID.'.jpg';            if (move_uploaded_file($file3['tmp_name'], $photoPath)) {                $mysqli->query('UPDATE Book SET photo3='.$photoPath.' WHERE bookID='.$bookID.'');            }        }    } catch(Exception $ex){        echo "ERROR:".$ex->GetMessage()."\n";        exit(1);    }}

The names do not match ['userfile']['photo1'] in your php. But on the iOS side userfile and photo1 are never used. Try using $_FILES['firstImage']

try this if you submit image in json format(repeat same code for other images by chnaging image name)

<?php                   $image          = $file;            $directorypath1 = $uploaddir;            $img            = str_replace('data:image/PNG;base64,', '', $image);            $img            = str_replace(' ', '+', $img);            $data           = base64_decode($img);            $name           = rand() . '_' . time() . ".jpg";            $img_path       = $directorypath1 . $name;            file_put_contents($img_path, $data);?>
