How to find out the number of attached files in go?

Question

go

I submit a form to the server to which I attach image files.
Initially, the number of pictures is not known.
The form looks like this
If the user has added several photos, it will

<input type="file" name="file_1">  
    <input type="file" name="file_2">

I'm taking data from a single file so `file, _, err := r.FormFile("file_1")`
how do I get the number of files in go and iterate over each one?

You don’t need to do this, you need to do multipart and set the multiple attribute to the input with files
