You can use FormData objects to send form data to your server.It will allow you to send both files and text data at the same time. You can find more information about it here.

index.html

<body ng-controller="myCtrl">
    <div class="file-upload">
        <input type="text" ng-model="name">
        <input type="file" file-model="myFile"/>
        <button ng-click="uploadFile()">upload me</button>
    </div>
</body>

In app.js, we create a custom directive fileModel, in which we listen for changes to the content of the input element and change the value of the variable in the scope accordingly. This is achieved using the $parse service to set the value in our scope.

app.js

var myApp = angular.module('myApp', []);

myApp.directive('fileModel', ['$parse', function ($parse) {
    return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function(){
            scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
            });
        });
    }
   };
}]);

// We can write our own fileUpload service to reuse it in the controller
myApp.service('fileUpload', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, uploadUrl, name){
         var fd = new FormData();
         fd.append('file', file);
         fd.append('name', name);
         $http.post(uploadUrl, fd, {
             transformRequest: angular.identity,
             headers: {'Content-Type': undefined,'Process-Data': false}
         })
         .success(function(){
            console.log("Success");
         })
         .error(function(){
            console.log("Success");
         });
     }
 }]);

 myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){

   $scope.uploadFile = function(){
        var file = $scope.myFile;
        console.log('file is ' );
        console.dir(file);

        var uploadUrl = "save_form.php";
        var text = $scope.name;
        fileUpload.uploadFileToUrl(file, uploadUrl, text);
   };

}]);

save_form.php

 <?php

     $target_dir = "./upload/";
     $name = $_POST['name'];
     print_r($_FILES);
     $target_file = $target_dir . basename($_FILES["file"]["name"]);

     move_uploaded_file($_FILES["file"]["tmp_name"], $target_file);

     //write code for saving to database 
     include_once "config.php";

     // Create connection
     $conn = new mysqli($servername, $username, $password, $dbname);
     // Check connection
     if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
     }

     $sql = "INSERT INTO MyData (name,filename) VALUES ('".$name."','".basename($_FILES["file"]["name"])."')";

     if ($conn->query($sql) === TRUE) {
         echo json_encode($_FILES["file"]); // new file uploaded
     } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
     }

     $conn->close();

?>
