Can an array be used to send an image in Ionic file upload?

I have an array of image URLs that looks like this:

["file:///data/user/0/io.ionic.starter/files/1542283317507.jpg",null,
 "file:///data/user/0/io.ionic.starter/files/1542283320931.jpg"]

I am attempting to upload this array, named 'final', using the fileTransfer upload function. However, I am encountering an error. Interestingly, the function works fine for individual images outside of the array. How can I successfully upload this array?

  fileTransfer.upload(final, url, options).then(
  data => {
    console.log(data);

    this.presentToast("Image uploaded successfully.");
  },
  err => {
    this.presentToast("Error while uploading file.");
  }
);

}

Thank you for your assistance!

Answer №1

Give this a shot, untested but should do the trick.

let tasks = [];
let images = ["file:///data/user/0/io.ionic.starter/files/1542283317507.jpg",
 "file:///data/user/0/io.ionic.starter/files/1542283320931.jpg"];

images.forEach((item) => {
  let uploadTask = fileTransfer.upload(<YOUR_FINAL>, item, <YOUR_OPTIONS>);
  tasks.push(uploadTask);
});

Promise.all(tasks)
.then((output) => {
  console.log('All images uploaded successfully!');
}
