ftp uploader, limit 100kb

[rschroers]

Hello,
I have developed a php script on my site offering my customers the possibility to upload data via ftp.
I established an ftp account in cpanel, and created a login for customers on my website, who then are able after successful login to upload documents within a php session.
Through a html form (action="uploader.php") using <input type="file" ...> the uploader.php then uses $_FILES and ftp_put with connection details to upload the file.
It works for file sizes less then 100kb, anything over 100kb produces an error.

Could you please advise me whether there is any restriction from the server side?
Can that be solved or increased?

Thanks,
Regards,
Ralf

Hi there,

ok, the php settings server side shouldn't be a problem. But what is wrong with it then?

Hi Adam,

here is the code for the 'uploader.php';
If files are larger than 100kb the $upload is false.

Hi Ralf,

I'm a little confused as to what you are trying to do with the script. Are you trying to upload the files to an FTP account on our server, or another server?

Hi Lee,

I'm uploading data on your/unlimited-space server. I created an ftp account and a folder and clients/users should be able to upload data with the given username password.

As I mentioned in my first post, it works, but only small files less then 100 kb.

Ralf

Hi Ralf,

I don't think you need to be using the FTP functions at all. When you post the file to the PHP script, it is uploaded to the server. You are then transferring it from the server, back to the server via FTP.

Here's a great guide to PHP file uploads: http://www.tizag.com/phpT/fileupload.php

While this doesn't explain the strange issue with the file size, removing the FTP part of the script might just fix it.

Hi Lee,

thanks for replying.

I saw that link and tried this before. However, one reason I did not use it that way, was that the permissions of the server folder have to be set to public read/write (77x, or similar)..

That's why I'm opening a certain, predefined ftp connection with username/password that points only to a specific folder.

Have to keep trying, I guess..

Hi there,

found the error. In my upload form the MAX_FILE_SIZE Value was set to 100000, i.e. 100kb.

Works ok now.

Thanks,
Ralf
