## Description

bool fdf_set_file ( resource fdf_document, string url [, string target_frame])

The fdf_set_file() selects a different PDF document to display the form results in then the form it originated from. The `url` needs to be given as an absolute URL.

The frame to display the document in may be selected using the optional parameter `target_frame` or the function fdf_set_target_frame().

Example 1. Passing FDF data to a second form
    <?php
      /* set content type for Adobe FDF */
      fdf_header();

      /* start new fdf */
      $fdf = fdf_create();

      /* set field "foo" to value "bar" */
      $fdf_set_value($fdf, "foo", "bar");

      /* tell client to display FDF data using "fdf_form.pdf" */
      fdf_set_file($fdf, "http://www.example.com/fdf_form.pdf");

      /* output fdf */
      fdf_save();

      /* clean up */
      fdf_close();
    ?>
