Question

you see the file_field provide a window to let the user select a certain file and upload to the server side.But what I want is just the file name.How could I just get the file name,I don’t need the file itself.anything suggestion?

Answer 1

you need to have two fields:

• hidden field to store filename
• file input to choose file

Ex:

<%= file_field_tag :our_file %>
<%= f.hidden :filename, :id => "hidden_filename" %>

little jQuery snippet:

$(document).ready(function(){
  $('input[type=file]').change(function(e){
    filename = $(this).val();
    $("#hidden_filename").attr("value", filename);
    # To reset file field if you don't want to uppload a file
    $(this).attr("value", "");
  });
})
