You aren't deleting the record from the database, just the file from the file system. You should add in there a:

db_query('DELETE FROM {files} WHERE fid = %d', $FID);

Also do that on any other linked tables you have added in.

Hi All

I am using Drupal 6.26.

 

I am trying to upload a file. One user can upload only one file.

After a while, if user wants to upload another file, I need to delete the first file and upload the second file.

To delete the first file, I do a query to get the first file name, deletes first file and uploads the second file.

After a while, if user wants to upload another file, when I do query to get the second file name (as I want to delete the second file now), I always get the first file name.

So I am not able to delete the second file.

 

Probably database cache plays a role here, how can I make sure, my query returns the latest data present in table, query should not pick the data from cache.

 

Please refer code below.

 

 global $user;
 $FID = -1;
 
 $result = db_query("SELECT fid, filepath FROM {resubmt_table} LEFT JOIN {files} USING (fid) WHERE resubmt_table.uid = %d", $user->uid);
 $obj = db_fetch_object($result);
 if($obj)
 {
  $FID = $obj->fid;
  if($obj->filepath)
  {
   if(file_exists($obj->filepath))
   {
    drupal_set_message("File exists deleting " . $obj->filepath);
    unlink($obj->filepath);
   }
   else
   {
    drupal_set_message("File does not exists, so not able to delete, file = " . $obj->filepath);
   }
  }
 }

 

Many times, I am not able to delete the file.

Please suggest how can I fix this issue.

 

Thanks
