Submitting a form that includes an <input type="file"/> in Angular 2: Best Practices

media.html

<form #form="ngForm" (ngSubmit)="uploadFile(form.value)">
  <input type="file" ngControl="inputFile" />
  <input type="text" ngControl="name"/>
  <button type="submit" >Upload</button>
</form>

media.ts

uploadFile(fileInput){
    console.log(fileInput); // this 
    this.mediaService.addMedia(fileInput).subscribe((response)=> {
        console.log(response);
      },
      (error) => {
        console.log(error.text());
      }
    );
  }

when I try to access the file input in line : console.log("fileInput");, it prints out:

inputFile:null

name: "asdasdasdasd"

This indicates that I am unable to retrieve the value of inputFile to send it to my server. Any advice on how to successfully capture it would be greatly appreciated. Thank you for your help!

Hello, in order to successfully send a file through a form tag, you need to include the attribute

ENCTYPE = "multipart/form-data"

within the form tag itself.

This attribute is crucial for enabling the uploading of files.
