These users are probably using a download manager. This type of software have this issue.

Only solution I can suggest is that when this download Manager window opens, they should click on Cancel. Immediately after that, the classic Windows download window will appear and they can download normally (save or open)

Hello Naval !

I am in big trouble as for an unknwon reason (at least for me !) the script is not working anymore suddendly ...

Each try to load a file resend me on the login page exactly as I was no logged then I am with no error from WB7

What can I do to check where can be the problem ?

You speak of the STAT() problem, how can I check if this is the issue ? any way to bypass that

Thanks in advance for your time and patience ...

Let me understand this correctly.....

You are sying that actually the user can't log in and is always sent to the login page ?

If yes, and you have not changed anything, then probbaly the issue is that sessions are no longer preserved in your site.

Can you log in normally in other protected pages (not the download page) ? If not, it is (almost certainly) an issue with sessions, and you should ask your hosting company to check it.

Arghhh ...

It seems I cant log to any page protected

I have added a "logging name" tool to my redirect after logging page and it say : "Welcome Not logged in"
So this seems a problem on the site itself not in your code

To help during fixing, can you see a mean to systematically allow the download, logged or not ?
What should I add or modify in the PHP code of the page to do that
At least visitors will can download !

Thanks in advance

Not sure what you are asking me....

If you want to allow download, to non logged in visitors, just remove the protection code from the downloader script, and you are done.

Hello
It was some time before I come back again with my questions ... :)

The logging system works like a charm no problem BUT to avoid boring visitors unnecessarily, how can I, once logged in, stay logged even if the visitor close his browser and shut off his computer ??
is there a way to save that somewhere ?
with this system, when the visitor come back, he will be directly logged

Thanks in advance for you valuable idea !

This is not possible, unless you modify the code yourself.

Ok
Seems difficult
Offering this possibility could be interesting anyway

edit : Does a system using cookie can achieve that may be ?

This might be due to server settings: memory_limit and buffer settings.

For big files there are different pieces of code that outut each chunk whithout buffering the entire file in memory. However, these are out of the limits of the free help I can provide in this forum.

In just a few words: No
The download is not immediate but through the script that "reads" the file and outputs it to the browser, so it is slower than a direct download.

However the difference should be minimum and not visible to the user.

I don't know why the "Pause" button is disabled. Furthermore the script might have issues with Download Managers as they usually download an empty php file instead of the file itself.

Thanks anyway for your help already

1) Only possible explanation is something wrong in your file names definition, lines

$file[1]= "filename1.pdf";
$file[2]= "filename2.doc";
$file[3]= "filename3.xls";
// Add as many as necessary


Check if the extensions used are correct.

2) There is no reason for this, at least not to my knowledge. Might be a server limitation ?

Thanks for your answer

Everything seems fine in the definition, and everything works well, just this TYPE wich is wrong even if the "Openw with ..." is ok

Anyway not a big deal !

For the file size, I need to check with my hoster, but will be complicate !

Thanks for all

Hello Naval
Hoping you still have an eye on this (old) thread
I try to improve my site step by step and discover recently the "Open link in Lightbox" function, which is working well

To make the process of download more fluent and not too complicate with multiples windows opening, I wonder if it could be possible to open the Login page in a lightbox ??
In this case the visitor stay on the downoload page (dimmed in the background) and when logging is filled successfullt, can click again the link to download

Hoping to be clear

Yes, it is clear, however at the moment I unfortunately don't have the necessary time to see how / if this can be done. Maybe within a few weeks.

Hello Naval

I dont know if you still monitor this old thread but unless someone can point me on the right direction for an equivalent feature, you are still my savior ... up to the last few days (weeks ?)

Since some time, strangely, the script stop working, keeping ro ask to logging even if already logged

Do you have an idea how I can debug that ? some variable to monitor ? I am really a noobs with php, keep it in mind

Thanks in advance for you valuable help

Most probably it is a server issue with the "session_save_path".
Often hosting companies make PHP updates and they change the default settings.

To verify if this is the case, try loging in and visiting a protected page (which does NOT contain the script).
If you can't visit that either, most probably the issue is what I mentioned.

Hello Naval

Glad to see you are still ready to help

My site is handled on AWS, feel that the discussion will not be easy ... :cry:

Thanks anyway

Just as a follow-up, I, of course, get nothing from Amazon neither from my IT, which hate seeing individual insisting to have their own website :)

I have checked, and PHP does not have a session_save_path variable set in php.ini. It does, however, use /tmp/ on the server for temp session files, which we use in IT all the time, to keep users connected to their own profiles and accounts.

One thing to keep in mind is that when the site is live it is on multiple servers in multiple Amazon data centres, using load balancing, the load balancer will keep the user to the same server, while the session is alive, based on the SESSION_ID cookie, which PHP issues and uses.

> So your application needs to understand that it will need to use php sessions to keep to one server
> Our servers are refreshed at least daily, and thus you can not store files on the server today and expect them to be around tomorrow.


It is clearly a Session problem, the more weird is that the site is working well in the buffer zone on AWS and dont works when bring live

Dont know how I will end with that :?

They are correct in saying that they use the /tmp directory and SHOULD work fine.
However, not always this is true.

Please test as I suggested and see if you can stay logged in a protected page (without the script), just to make sure that sessions work ok.
