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.
