Script works on one server, but not the other

JiggaMan

I have a flash movie, that sends variables out to a PHP script, which is then printed into a .txt file.

Here is the PHP script:

<?php 
$user         = $_POST['user']; 
$Email        = $_POST['Email']; 
$Today        = $_POST['Today']; 
$Comments     = $_POST['Comments']; 

if ($Submit == "Yes") { 

$filename     = "news.txt";      

$fp         = fopen( $filename,"r");      

$OldData     = fread($fp, 80000);      

fclose( $fp );      

$Today         = (date ("l F dS",time()));      

$Input = "<b>$Email</b><br>Posted By: <b>$user</b> on <b>$Today</b><br>   $Comments<br><br>";      

$New = "$Input$OldData";      

$fp = fopen( $filename,"w");      

if(!$fp) die("&news=cannot write $filename ......&");      

fwrite($fp, $New, 800000);      

fclose( $fp ); 
}

$filename = "news.txt";      

$fp     = fopen( $filename,"r");      

$Data     = fread($fp, 800000);

fclose( $fp );      

$DataArray = split(".:::.", $Data);      

$NumEntries = count($DataArray) - 1;     

print "&TotalEntries=$NumEntries&NumLow=$NumLow&NumHigh=$NumHigh&news=";      

for ($n = $NumLow; 
$n < $NumHigh; $n++) {      

print $DataArray[$n];          

if (!isset($DataArray[$n])) {             

Print "";              

exit;       

} 
} 
?> 

I chmod777 the .txt files and it works PERFECT on one server.. but then I try putting it on the server I need it to work on.. and it doesnt work? Any ideas why?

Thanks Fellas

if ($Submit == "Yes") {

Check the register_globals settings. Looks like you are relying on the being set to "On" here.

Actually yes, they are off... how do I get them turned on?

Also, they wern't global variables before.. and had the same outcome. worked on one server, but not on the next.

LordShryku

run phpinfo()

If the server that works has register_globals on, and the other one doesn't, that's your problem. If register_globals is on, it'll automatically declare them as globals. So, yes, they would have been global variables.

JiggaMan

yea thats exactly it..

how do i turn them on? I dont have acess to the php.ini file.. so what can I do?

LordShryku

When you do this:

$user         = $_POST['user'];

You are checking for the posted user. Same would apply for the submit button:

// Instead of
if ($Submit == "Yes") {
// use
if ($_POST['Submit'] == "Yes") {

And do that for any variables that you expect to be posted.

Just as a general note, you should also be checking to see if they are set. ie.

if(isset($_POST['user'])) {
   $user = $_POST['user'];
}

if(isset($_POST['Submit']) && $_POST['Submit'] == "Yes") {

and so on...

surprising that you want them turned on when you're using the $_POST array.... do you know why you're doing that or did u just learn that way?

The_Chancer

As a recommendation turn them off on your test server - thay way it'll work even if they are on....

On a unrelated note, consider not relying on submit button name/value pairs but rather use a "hidden" form element instead. Submit button information is not always sent (I forget the exact circumstances but there are some, although it's rare). For example you might add this to your form:
<input type="hidden" name="action" value="form_submitted">
And check it by something like:
if ($_POST['action'] == 'form_submitted') {
