import { Component } from "@angular/core";
import { IonicPage, NavController, NavParams, normalizeURL } from "ionic-angular";
import { Http, Headers } from "@angular/http";
import "rxjs/add/operator/map";
import { NgForm } from "@angular/forms";
import { ToastController } from 'ionic-angular';
import { Camera, CameraOptions } from '@ionic-native/camera';


@IonicPage()
@Component({
  selector: "page-creat-actor",
  templateUrl: "creat-actor.html"
})
export class CreatActorPage {

    actorName:string;
    actorCountry:string;
    actorFirstMovie:string;
    actorBestMovie:string;
    actorImdbBestMovie:string;
    image:any;


  constructor(
    public navCtrl: NavController,
    public navParams: NavParams,
    public http: Http,
    private toastCtrl: ToastController,
    private camera: Camera
  ) {}

  

  presentToast() {
    let toast = this.toastCtrl.create({
      message: 'Actor was added successfully',
      duration: 4000,
      position: 'top'
    });

    toast.present();

  }

  selectphoto(){

    const options: CameraOptions = {
      quality: 50,
      destinationType: this.camera.DestinationType.FILE_URI,
      sourceType: this.camera.PictureSourceType.PHOTOLIBRARY,
      saveToPhotoAlbum: false
    }

    this.camera.getPicture(options).then((imageData) => {
      // imageData is either a base64 encoded string or a file URI
      // If it's base64 (DATA_URL): base64Image = 'data:image/jpeg;base64,' + imageData;
      this.image = normalizeURL(imageData);
     }, (err) => {
      // Handle error
     });

  }

  onSubmit(form:NgForm){

      console.log('img' , this.image);

      this.actorBestMovie = form.value.actorBestMovie;
      this.actorCountry = form.value.actorCountry;
      this.actorFirstMovie = form.value.actorFirstMovie;
      this.actorImdbBestMovie = form.value.actorImdbBestMovie;
      this.actorName = form.value.actorName;
      this.actorpost();

      form.reset();

  }

  actorpost() {
    // let headers = new Headers();
    // headers.append("Accept", "application/json");
    // headers.append("Content-Type", "multipart/form-data");

    let body = new FormData();
    body.append('name',this.actorName); 
    body.append('country',this.actorCountry );
    body.append('first_movie',this.actorFirstMovie);
    body.append('best_movie',this.actorBestMovie);
    body.append('imdb_best_movie',this.actorImdbBestMovie);
    body.append('file',this.image);


    this.http.post("http://localhost/slreview-api/public/api/actors",body)
      .map(res => res.json())
      .subscribe(
        data => {
          console.log("data => ", data);
        },
        error => {
          console.log('Error => ', error);
        },
        () => {
          console.log('Completed!');
          this.presentToast();
        }
      );
