Creating a (correct???) download link

By maen on 10 Sep 2015 at 19:15 UTC

I don't get the download to work. I googled a lot but I don't see my fault, anybody does???

So what I did:

A csv file is created and stored in: $uri = "public://tmp".'/'.$filename;
For the moment this is: /sites/default/files/tmp/.
The file exists in the db.file_managed table and also a web-accessible URL for a stream to an external or local file.:

$file_object = file_save_data($data, $uri, FILE_EXISTS_RENAME);
$url = file_create_url($file_object->uri);

The file exists, it's all on my localhost so the permissions are:
(duke is my name on my pc, every folder has chmod -R 775)

- drwxrwxr-x 8 duke www-data  4096 Sep 10 19:59 files
- drwxrwxr-x 4 duke www-data 4096 Sep 10 20:42 tmp

A generated file has the following, e.g.:

-rw-rw-r-- 1 www-data www-data    5 Sep  9 22:27 adress_list_2015_09_09_22_27_11.csv

So I think that the Apache could read/write the file!???

I made a download link like this,

$options_download['attributes']['download'] = $filename;
   // We need query-params for download-token here.
   $dl_link = l(t('Download'), $url, $options_download);

... and set it in drupal_set_message():

  drupal_set_message(
     t('!download',array('!download'=>$dl_link))
    );

If I click on the link, I get the following text (translated from German):
File not found: Files under .../sites/default/files/tmp/adress_list_2015_09_10_21_10_10.csv could not be found.
If I refresh the site in browser I get:
You don't have permission to access /musik/sites/default/files/tmp/adress_list_2015_09_10_21_10_10.csv on this server. And I'm admin here!???

So does anybody knows what I'm doing wrong? As i stated: this is public file...

Thx in advance,

maen

I at least need to see the chunks of code in context. Note placing files in tmp is not a good practice. And from what you are showing you seem to be missing some code for managing the file.

my code:

Without the creation of the content of data(Firstname etc. ...) this is my complete code:

    $now = date("Y_m_d_H_i_s");
    $filename='adress_list_'.$now.'.csv';
    $uri = "public://tmp".'/'.$filename;
    
    $file_object = file_save_data($data, $uri, FILE_EXISTS_RENAME);
    if (!empty($file_object)) {
      $url = file_create_url($file_object->uri);
      $_SESSION['adressliste_csv'] = $file_object->uri;
      $options_download['attributes']['download'] = $filename;
          $dl_link = l(t('Download'), $url, $options_download);
      drupal_set_message(
       t('!download',array('!download'=>$dl_link))
    );

The issue with tmp I will solve later. So which code do I miss????
