FTP Upload Script File Size Issues

I am struggling with getting this script to work. The idea is to have clients upload their large files via a web based site to our in house FTP server.

 

I have gotten it to work error free with file sizes up to approx. 6.7mb. Which leads me to believe its an issue with file size restrictions. I have added the lines 

Ini_set("upload_max_filesize","1000M");

and 

Ini_set("post_max_size","1000M");

but still receive the below error.

 

Notice: Undefined index: submit in E:\www\mymarketinglab.com\clientlogin\general\upload-file.php on line 63

 

Notice: Undefined index: submit in E:\www\mymarketinglab.com\clientlogin\general\upload-file.php on line 70

 

Any ideas what could cause this?

well the message you are seeing is just a notice telling you that the post element "submit" does not exist. so either it doesn't exist in your form, or the form has not been submitted. also, verify you are using POST and not GET, i like to use $_REQUEST which covers both of them...

Both of those settings cannot be set using ini_set() statements. They are both PHP_INI_PERDIR, which means "Entry can be set in php.ini (either the master php.ini or in a local php.ini when php is running as a CGI application), .htaccess (when php is running as an Apache Module) or httpd.conf (Apache web servers only.)"

I've tried editing both a php.ini template as well as one I created with just the edited values I need, both resulted in a page that says the following:

 

This PHP CGI binary was compiled with force-cgi-redirect enabled. This means that a page will only be served up if the REDIRECT_STATUS CGI variable is set, e.g. via an Apache Action directive.

 

For more information as to why this behaviour exists, see the manual page for CGI security.

 

For more information about changing this behaviour or re-enabling this webserver, consult the installation file that came with this distribution, or visit the manual page.

 

I have never adjusted the php setting from the server side and am pretty much learning by doing...

 

Any help would be great.

Cannot really help you without knowing what your web host expects in the php.ini and what you put into it. It would be best if you contacted your web host to find the exact method you would need to use to change those settings.
