Help about posting variables to a new file

scald

i use a hosting which supports php. Everything was right about my php script until my hosting upgraded their php version to 4.2.3 , after that some structures in my php scripts start to produce some errors.
i read
http://www.phpbuilder.com/board/showthread.php?s=&threadid=10216198 is similiar to mine,
but my problem is little different.

for example, i have a form in a page is like that;
from main.php
<form method="POST" action="send.php">
<textarea rows="10" name="S1" cols="37"></textarea>

and my send.php:
<?php

$fp = fopen ("text.php", "a+");
$fileBuff = fread($fp, filesize("text.php"));
fwrite($fp, "
<p align=center>
###############
Comments: $S1
IP: $REMOTE_ADDR
##############3
</p>

");
fwrite($fp,$fileBuff);
fclose($fp);
?>

but after the system upgraded 4.2.3 , i cant see entries and ip's on text.php, how can i use variable $S1 as a global variable , and where should i use it as a global variable.

i really need help,
thanks for any assistance.

I pasted your send.php code onto a sever running php 4.2.3 and it works fine. If you had wrapped your code in a function then use something like

function xxx()
{
global $S1;
echo $S1;
}

Better yet, use $_POST('S1');
The need to use the global keyword goes away.

By the way, it appears that you are trying to put the most recent post at the beginning of the test.php file. The code (as written) won't do this. Opening a file in append mode causes the file pointer to automatically move to the end of the file. Instead, you probably want to read the contents of the file then open it for writing, write the latest post then the saved contents.

thanks
but it didnt work,
result in test php:
############### Comment: Array('S1') IP: ##############3
i used inside the fwrite function in send php , and result was this while i entered some inputs to the form.

by the way, i rearranged send.php
$fp = fopen ("test.php", "r+");
$fileBuff = fread($fp, filesize("test.php"));
rewind($fp);

i wanted to see the latest post at the end instead of beginnning.
but this will show the post at the beginning.

do you have another solution for part 1?

I am not clear as to what exactly has been changed. Can you paste exact copies of your main.php and send.php? The problem could be in the way the form is setup.

This works on my site:
main.php
<html>
<body>
<form method="POST" action="send.php">
<textarea rows="10" name="S1" cols="37"></textarea>
<input type="submit" value="Post" />
</form>
</body>
</html

send.php
<?php

$fp = fopen ("text.php", "a+");
$fileBuff = fread($fp, filesize("text.php"));
fwrite($fp, "
<p align=center>
###############
Comments: $S1
Or: $_POST[S1]
IP: $REMOTE_ADDR
##############3
</p>

");
fwrite($fp,$fileBuff);
fclose($fp);
?>

it did, thank you very much.
in first reply you said
$_POST('S1')

it didnt work, but this time i used (from your 2nd reply)
$_POST[S1]

it did,
also i had a problem with
$REMOTE_ADDR
so i changed it to:
$_SERVER[REMOTE_ADDR]
it worked too.

thanks again you are great.

on the other hand, i have many scripts installed on server, i do not want to edit all my files. Can i set global registers on for my account on the server ? if it can be, can someone explain?

ahundiak

It depends on your provider. Registering everything as a global is sometimes considered to be a security risk. But you can try adding

php_flag register_globals on

</IfModule>

to $HOME/.htaccess then use phpinfo() to see if it worked.
