URL Variables and Windows XP

[GBrigden]

Hi,
As a new user of PHP, I have hit a problem. I am trting to call a PHP from my .js file. Using the getURL statement, I am passing 3 params to the .php but the .php is ignoring them. Is there something I am missing, possibly in the set-up.

TIA,

Gary

Sorry......the js looks like this
'
this.url = url;
var params = [
"file="+this.file,
"start="+start,
"length="+length
];
getURL(this.url + "?" + params.join("&&quot, this);'

and the php like this.....

'#
# This is a simple attempt to prevent the download of just
# any file on our server
#
if ( eregi("\.svg$", $file) ) {
#
# It's an SVG file so get the file's size
#
$size = filesize($file);

if ( $start == -1 ) {.........'

I get an error when the php comes across the $file and $start, both of which are passed by the getURL....

Thanks again.

try using $_GET[file] and $_GET[start] in your php. ______________________________________________________________________

Thanks for the help...
I have now set the code to......
'#
# This is a simple attempt to prevent the download of just
# any file on our server
#
if ( eregi("\.svg$", $_GET[file] )) {
#
# It's an SVG file so get the file's size
#
$size = filesize($_GET[file]);

if ( $_GET[start] == -1 ) {

#
# -1 is used to specify that the calling routing
# wants to know the size of the file that is
# being downloaded. Tell 'em how big it is.
#
print $size;.....'

but get an 'use of undefined constant file - assumed file' and 'use of undefined constant start - assumed start' .

Is your php.ini register_globals variable set to "On" ? It could help...

Thanks for the response....I have checked the ini file and the variable is On, but still getting same error...

Here is the code in full:

<?
set_magic_quotes_runtime(0);

#
# This is a simple attempt to prevent the download of just
# any file on our server
#
if ( eregi(&quot;\.svg$&quot;, $_GET[file] )) {
#
# It's an SVG file so get the file's size
#
$size = filesize($_GET[file]);

if ( $_GET[start] == -1 ) {

#
# -1 is used to specify that the calling routing
# wants to know the size of the file that is
# being downloaded. Tell 'em how big it is.
#
print $size;

} elseif ( $_GET[start] < $size ) {

#
# Otherwise we are being asked for a chunk of the
# file
#
if ( ( $_GET[start] + $_GET[length] ) > $size ) {

#
# Oops. Asked for too many bytes from the
# current position. Re-adjust to how much we
# really need to read.
#
$size = $size - $_GET[start];

}

#
# Open the file for reading.
# Really should be error checking from here
# on down.
#
$fh = fopen($_GET[file], &quot;r&quot;

#
# Move to the position where we should begin
# reading
#
fseek($fh, $_GET[start]);

#
# Read the requested number of bytes and send
# those back to the calling routine
#
print fread($fh, $_GET[length]);

#
# All done. Close the file
#
fclose($fh);

} else {

#
# The start position in the file is passed the
# end of the file. That means we're all done.
#
print &quot;done&quot;;

}
} else {

#
# Really should return some sort of violation error here
#
print &quot;done: invalid doc type: $_GET[file], $_GET[start], $_GET[length]&quot;;

}
?>

What I am trying to achive is to load a text file bit by bit returning the text to a var in javascript and allowing me to then parsexml..Any ideas?

Thanks
