Confused about upload script

[jimjiminyjimjim]

I have the following code for an upload form. I am a bit confused as to what should be set for the destination of the upload. I realise that C:\data is a windows file system and I am currently testing it on OSX.

 
<?php

/*Script name: uploadFile.php
* Description: Uploads a file via HTTP using a POST form
*/
if(!isset($_POST['Upload']))
{
	include("form_upload.inc");
} # endif

else
{
if($_FILES['pix']['tmp_name'] == "none")
{
echo "<b>File did not successfully upload. Check the file size. File must be left than 500k.<br>";
include("form_upload.inc");
exit();
}
if(!ereg("image",$_FILES['pix']['type']))
{
echo "<b>File is not a picture. Please try another file.</b><br>";
include("form_upload.inc");
exit();
}
else
{
	$destination = 'c:\data' . "\\".$_FILES['pix']['name'];
	$temp_file = $_FILES['pix']['tmp_name'];
	move_uploaded_file($temp_file,$destination);
	echo "<p><b>The file has sucessfully uploaded:</b>
	{$_FILES['pix']['name']}
	({$_FILES['pix']['size']})</p>";
	}
	}
	?>

If I change c:\data to something like /library so that it is an OSX destination I get the following error -

Warning: move_uploaded_file(/Library\Picture 6.jpg): failed to open stream: Permission denied in /Library/WebServer/Documents/uploadFile.php on line 9

What am I doing wrong? Also if I wanted to change the code so that it uploaded to a server what would be the correct address to put for the destination? All I need is the file to upload to the same directory as this php file.

"Permission denied in /Library/WebServer/Documents/uploadFile.php on line 9 "

Sounds like the perms on that directory do not allow the process to write to that location.

[jimjiminyjimjim]

If I have not got permission to write there is that a problem with the script or that the location can't be written to due to my systems settings?

If I was to ignore the writing to a hard disk because that was just for testing purposes and wanted it to upload to my webspace what should I type instead of C:\data? And do I have permission to write to this space through the script. (its a commercially provided webspace)

[maxpup979]

its a system issue. if you dont have perms to write to the directory, you will get that error. for the webspace, I believe (although I could be wrong) that you can also set up the directory on the webscape to be pretty much anything you want...just create the directory, and reference it in your script.

if u were using a linux machine...you could chmod to 777, but since ur using windows....right click on teh folder and select properties...and make sure that write is checked

if your host is running Unix/Linux you will have to get the absolute path of your upload folder, usually something like
/home/username/html/upload_dir/

If its running Windows then it will be similar to c:\data\
you can get the value by checking the "DOCUMENT_ROOT" setting.

create a file called: docroot.php

and add

<?php
echo $_SERVER['DOCUMENT_ROOT'];
?>
