How to upload files from various input fields using Angular 7

Currently, I am working with Angular 7 and typescript and have a question regarding file uploads from multiple input fields in HTML. Here is an example of what I am trying to achieve:

<input type="file" (change)="handleFileInput($event.target.files)">
<input type="file" (change)="handleFileInput($event.target.files)">
<input type="file" (change)="handleFileInput($event.target.files)">

I am aware of the 'multiple' attribute, but unfortunately, I cannot use it in this case because I need to change the name of each file to match the value of an enum in my Spring Boot application.

Answer №1

Generate a single input field and assign various parameters to it.

<input type="file" multiple>

Answer №2

No need to clutter your website with multiple file input fields. Just one will do the job, allowing users to upload several files at once.

<input type="file" name="img" multiple>

The 'multiple' attribute is a handy boolean attribute that lets users input more than one value in the element. To select multiple files, simply hold down the CTRL or SHIFT key while making your selections.

Answer №3

Even with just one input, you have the ability to give each file a unique name:

  onChange(files: FileList) {
     Array.from(files).forEach(file => {
       //INSERT YOUR CODE HERE TO CUSTOMIZE THE FILE NAMES
      });
 }
