Cannot download results of webform with Internet Explorer

I get the same issue with version 6.x-2.3

Same error message, same browser.

In addition to it working fine with Firefox, it also works fine with Chrome and Opera

I have been doing some research on this, and I believe it is an IE issue with the headers from what I have been able to cobble together so far, but haven't yet found anything definitive. Will keep looking and report back if I find out anything that may be useful.

Thanks

Well, it's not definitive, but I found a solution that seems to work

From this post that describes the same issue, though he traces it to an IIS issue

There were a lot of great comments in the post, and it seems that it is an IE issue. The fix that works for me is to add 2 headers, before the other 2 headers before outputting the file. (sorry, not very clear).

There are 2 changes to make

In the webform_export.inc file...

The function below is found in the class named webform_exporter_delimited

  function set_headers($filename) {
    parent::set_headers($filename);

    // Convert tabs.
    if ($this->delimiter == "\t") {
      $extension = 'tsv';
      $content_type = 'text/tab-separated-values';
    }
    else {
      $extension = 'csv';
      $content_type = 'text/csv';
    }

    drupal_set_header("Content-type: $content_type");
    drupal_set_header("Content-Disposition: attachment; filename=$filename.$extension");
  }

The function below is found in the class named webform_exporter_excel

  function set_headers($filename) {
    drupal_set_header("Content-Type: application/x-msexcel");
    drupal_set_header("Content-Disposition: attachment; filename=$filename.xls");
  }

In both cases you should see this:

    drupal_set_header("Content-Type: application/x-msexcel");
    drupal_set_header("Content-Disposition: attachment; filename=$filename.xls");

Change this (by adding two header calls before the existing ones) to:

    drupal_set_header("Pragma: public");
    drupal_set_header("Cache-Control: max-age=0");    
    drupal_set_header("Content-type: $content_type");
    drupal_set_header("Content-Disposition: attachment; filename=$filename.$extension");

This has worked for me so far with limited testing

Back to the post I referenced above, there are a lot of good comments there, but I think you will agree that none of them are quite definitive, so further research is probably warranted.

drupal_set_header("Pragma: public");
drupal_set_header("Cache-Control: max-age=0");

Please upgrade to Webform 2.6, since I believe this problem has been corrected already.
