It's not clear to me what you're asking. I think you're saying that you wish to obtain the IP of the machine you're using to browse the Web so that you can send it to a Linux server. If that's the case, you'll just need to run something like ipconfig or winipconfig to see what your IP is. Of course, you could also write a little script and include getenv("REMOTE_ADDR") and hit the script with your local machine to get the IP address. If neither of those suggestions answers your question, please try to clarify.

If I understand accurately the method you've proposed for having users upload their files, you're confused about how the process works. You can't simply specify the IP address and path and automatically have access to any file on the user's system (though I'm frankly a little surprised Microsoft doesn't allow that).
Check out http://php.resourceindex.com/Comple...File_Uploading/ for some scripts you might look at to get ideas for how to do this. For starters, your form will need to have an "enc-type" attribute so that it can process the uploaded file. Once you've done that, you'll need to do some validation in your PHP code to make sure people can't upload maliciously or overwrite important files like /etc/passwd. Then you'll just do whatever you want with the file that's been uploaded. If you're putting it in a database, you should probably use a blob field rather than a text field. I'd recommend instead storing the image on the server somewhere and putting a reference to it in the database, though this'd involve some checks to make sure you don't overwrite existing images. You save yourself database overhead by doing it this way. You also save yourself the trouble of having to output content headers when spitting the images back out. Whatever you decide, you should forget this IP method and work on making sure you specify the enc-type in your <form> line and then process the $_POST variable for the upload field as a buffer containing the raw data of the image file.

Ali,
Try adding this encoding type to your form tag: [code] <form method="POST" action="testing123.php" enctype="multipart/form-data"> If you notice the error message that's being spit out when you're trying to connect to the linux box, it's adding extra slashes... But if you notice, your directory "$c" doesn't have a slash added to it.... In PHP, variables must start with a $ sign.. Try escaping the $ sign in your directory... My suggestion would be to NOT use a directory with that style... Remove the $ and create a directory that doesn't make use of special characters.

I'm still confused on how c$ translates into c:?! The "enctype="multipart/form-data" will specify the form as sending multi-part data, which is binary data (non-text)... So when you're choosing the file from the "browse" box, it will transfer the file as binary data so that you can then process it, using your PHP, however you like. Try this: - Put the enctype coding in your form tag, and select a file to upload. - In your PHP script, output the filename that is sent from the form: Code:
echo("Filename: " . $_FILES['name_of_form_field']);
Replace "name_of_form_field" with whatever name you gave your "filename" field in the form... And see what is output. Let me know...
