Selecting Image from Gallery or Camera


#1

Here, I can open camera and select image from gallery, but how to upload image to sever PHP, use POST method.
This is my code:

openeditprofile() {
    let actionSheet = this.actionsheetCtrl.create({
      title: 'Option',
      cssClass: 'action-sheets-basic-page',
      buttons: [
        {
          text: 'Take photo',
          role: 'destructive',
          icon: !this.platform.is('ios') ? 'ios-camera-outline' : null,
          handler: () => {
            this.takephoto();
          }
        },
        {
          text: 'Choose photo from Gallery',
          icon: !this.platform.is('ios') ? 'ios-images-outline' : null,
          handler: () => {
            this.openGallery();
          }
        },
  ]
});
actionSheet.present();

}

 takephoto() {
>      const options: CameraOptions = {
>        quality: 100,
>        destinationType: this.camera.DestinationType.DATA_URL,
>        encodingType: this.camera.EncodingType.JPEG,
>        mediaType: this.camera.MediaType.PICTURE
>      }
> 
>      this.camera.getPicture(options).then((imageData) => {
>        // imageData is either a base64 encoded string or a file URI
>        // If it's base64:
>        this.base64Image  = 'data:image/jpeg;base64,' + imageData;
>        this.photos.push(this.base64Image);
>        this.photos.reverse();
>      }, (err) => {
>        // Handle error
>      })}
> 
>     openGallery() {
> 
>     const options: CameraOptions = {
>       quality: 100,
>       destinationType: this.camera.DestinationType.DATA_URL,
>       encodingType: this.camera.EncodingType.JPEG,
>       mediaType: this.camera.MediaType.PICTURE,
>       sourceType: this.camera.PictureSourceType.SAVEDPHOTOALBUM
>     }
> 
>     this.camera.getPicture(options).then((imageData) => {
>       // imageData is either a base64 encoded string or a file URI
>       // If it's base64:
>       this.base64Image  = 'data:image/jpeg;base64,' + imageData;
>       this.photos.push(this.base64Image);
>       this.photos.reverse();
>     }, (err) => {
>       // Handle error
     })}

Getting the image path from the camera plugin

Sorry having a hard time looking at your code - can you put it all into a concise code block like you have for the bottom bit?


#3

ok…I have fixed it

That’s better.

For one I’m a sucker for tidy code… so how about something a little easier on the eye…

  openeditprofile() {
    let actionSheet = this.actionsheetCtrl.create({
      title: 'Option',
      cssClass: 'action-sheets-basic-page',
      buttons: [
        {
          text: 'Take photo',
          role: 'destructive',
          icon: !this.platform.is('ios') ? 'ios-camera-outline' : null,
          handler: () => {
            this.captureImage(false);
          }
        },
        {
          text: 'Choose photo from Gallery',
          icon: !this.platform.is('ios') ? 'ios-images-outline' : null,
          handler: () => {
            this.captureImage(true);
          }
        },
      ]
    });
    actionSheet.present();
  }


  async captureImage(useAlbum: boolean) {
    const options: CameraOptions = {
      quality: 100,
      destinationType: this.camera.DestinationType.DATA_URL,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,
      ...useAlbum ? {sourceType: this.camera.PictureSourceType.SAVEDPHOTOALBUM} : {}
    }

    const imageData = await this.camera.getPicture(options);

    this.base64Image = `data:image/jpeg;base64,${imageData}`;

    this.photos.unshift(this.base64Image);

  }

Now you’re down to one method that can deal with both situations captureImage. It’s also using async which makes your Promise more legible.

I am assuming you at least know how to write a php endpoint which can take a POST.
If so, post the actual image as a base64 string and assemble on the server…

function base64_to_jpeg($base64_string, $output_file) {
    // open the output file for writing
    $ifp = fopen( $output_file, 'wb' ); 

    // split the string on commas
    // $data[ 0 ] == "data:image/png;base64"
    // $data[ 1 ] == <actual base64 string>
    $data = explode( ',', $base64_string );

    // we could add validation here with ensuring count( $data ) > 1
    fwrite( $ifp, base64_decode( $data[ 1 ] ) );

    // clean up the file resource
    fclose( $ifp ); 

    return $output_file; 
}

I use ionic 2… you can make for ionic 2


#6

Is that a question or a statement?


#7

Oh no, My English is not good, I can not exchange more


#8

English is an advantage when it comes to most documentation in the world.

You need an endpoint which can accept a post.

You need to post your image within an object, such as { "imageBase64" : "<stringhere>" }

I’ll stop there for now. Good luck!
