Need a little help

bobert5696

Ok, i need some help writing a script. I need it to do this.

when the page http://blah.com/Updater.php?version=infohere&version2=infohere

i want were it says infohere to be written to a file, i have looked for tutorials, but i cant find one doing exactly what i want, and i can't figure it out by myself, so if anyone can help, that would be great

dagon

Something like this perhaps.

file_put_contents(file_name,$_GET['version']);

bobert5696

Up where? did it create\ write the file? do you have permission to write in the directory?

bobert5696

i created the file Data.txt for it to write in... nothing came up there after i went to
http://mysitehere/Updater.php?version=test

Updater.php is this:

<?
file_put_contents(Data.txt,$_GET['version']); 
?>

bradgrafelman

The filename should be a [man]string[/man].

bobert5696

ok, my host was being stupid, so i was using old code, but when im using

<?
file_put_contents('Data.txt',$_GET['version']); 
?>

i get this error:
Fatal error: Call to undefined function: file_put_contents() in /home/www/********.awardspace.com/Updater.php on line 2

ok your not using php5 so you need to use fopen(), fwrite(), and fclose() instead.

bradgrafelman

[man]file_put_contents/man is a function that was introduced in PHP5 (which is why I never use it). Since you're running PHP4, you'll need to use [man]fopen/man, [man]fwrite/man, and [man]fclose/man individually.

bobert5696

ok, i was thinking something like that, so it would be

fopen('Data.txt');
fwrite($_GET['version']);
fclose('Data.txt');

is that right?

Nope. I'd suggest you visit those manual pages and see how the functions work.

bobert5696

ok, so

$myFile = "/home/www/*******.awardspace.com/Data.txt";
$handle = fopen($myFile, 'a')
fwrite($handle, $_GET['version']);
fclose($handle);

bradgrafelman

Well, that should write the GET variable right after the previous one, without a line break or anything. Do you have any questions?

bobert5696

so to do the whole thing it would be:

$myFile = "/home/www/*******.awardspace.com/Data.txt";
$handle = fopen($myFile, 'a')
fwrite($handle, $_GET['version']);
fwrite($handle,"/n");
fwrite($handle, $_GET['version2']);
fwrite($handle,"/n");
fwrite($handle,"/n");
fclose($handle);

so that would write it like this:
Info
Info2

Info3
Info4

bradgrafelman

Almost - the special escape sequences used in double-quoted strings use backslashes, not forward slashes, so "\n" would give you a line break.

Also note that you could/should do this all in one fwrite() call:

fwrite($handle, $_GET['version'] . "\n" . $_GET['version2'] . "\n\n");

Also, don't forget to check if the two GET variables are even set before you try to write them to a file (a function like [man]isset/man would help).

bobert5696

ok, thank you SOOOO much

Don't forget to mark this thread resolved.
