Input of type file that automatically selects files?

  • 772

I have an input of type file and with the multiple property , that is, I can select several files. Specifically, I need to send three types of files to the server:

 1. archivo.shp
 2. archivo.shx
 3. archivo.dbf

I would like that in the menu to choose input files when selecting any of the previous files automatically select the others (if they exist). That is, if I select archivo.shp, I also select archivo.shx and archivo.dbfif they exist in the same path as file.shp.

How could I implement something like that with JavaScript?

    According to the documentation this cannot be done for security

    The file input type creates a field through which users can upload files from their local computer or network. The VALUE attribute specifies the name of the initial file, but it is typically ignored by browsers as a security precaution.

    1. You should check if the file exists!
    function fileExists(path) {
  try {
    if(fs.accessSync('/nombre del archivo')) {
      return true;
    }
  } catch (e) {
    return false;
  }
}

    then change the format of your file from .shp to .shx and .dbf

    and use the function above to check if there are those files with different format.
