Write to file problem - very weird.

Hi guys, i have a problem.. basically this is my part of my code

Code:

---

<?php
$s = $_GET['s'];
$shout_file ="$s.php"

file_put_contents($shout_file, $chat_line, FILE_APPEND);

---

what my aim is is so that when a user goes to mysite.com?s=chatroom1

the chatroom will write the message to $shout_file

(chatroom1.php)

same if they go to ?s=chatroom2

e,t,c

now the issue is, that its not writing to the $shout_file but it defo is getting the ?s= cause if i put print $s;

it prints it to the page... which is odd

but if i change it to $shout_file ="chatroom1.php"

it works perfect..

Any ideas why?

Thanks,
Jamie.

Try:

PHP Code:

---

<?php
$s = $_GET['s'];
$shout_file = $s.'.php';

file_put_contents($shout_file, $chat_line, FILE_APPEND);
?>

---

There wasn't a ; on the end of the line too but I'm guessing that was a typo in here because that would have gave you an error.

Same thing, this is so weird!!

if i put

$shout_file = "Vital.php";


it works and writes to Vital.php

but even when i put

$shout_file = $s.'.php';

it dont write to Vital.php

(P.s 0 my url is ?s=Vital) so i dont understand where the issue is coming from!

How about:

PHP Code:

---

<?php
$s = 'Vital';
$shout_file = $s.'.php';

file_put_contents($shout_file, $chat_line, FILE_APPEND);
?>

---

If that works then I'm thinking your input isn't strictly "Vital". Try something like the following to check there is no trailing spaces:

PHP Code:

---

<?php
$s = $_GET['s'];
$shout_file = $s.'.php';

echo '[' . $shout_file . ']';
?>

---

This is so weird,

that dont work either it

but when i do

echo '[' . $shout_file . ']';

it echos right Vital.php

but still isnt writing to the file.... this is weird.

any ideas?

Cheers,

What happening with this code?
Id expect it will either output true and write to the file twice or false and not write only once.
If you get false there is something wrong with the input string.

PHP Code:

---

<?php
$s = $_GET['s'];
$shout_file = $s.'.php';

$tester = 'Vital.php';
echo ($tester == $shout_file);
if ($tester == $shout_file) {
  file_put_contents($tester , $chat_line, FILE_APPEND);
  file_put_contents($shout_file, $chat_line, FILE_APPEND);
}
else {
  file_put_contents($tester , $chat_line, FILE_APPEND);
  file_put_contents($shout_file, $chat_line, FILE_APPEND);
}
?>

That worked and showed the number 1 :S

im lost

wys it work there but not on my script above :S

Showed 1 (true) and updated the file twice or just once? If twice then it suggests the url was not correct the other times.
