PHP sessions
HI
I have a problem with my sessions. I'm writing a chatroom. After I logged in(log_inn.php) it goes to Chat_test.php that loads a Iframe(rows.php) and when you submit the text, it runs chat_sub.php. After I log in, I print the $_SESSION as the usename "Welcome $_SESSION" , but after the first time I submit my form, I loos my session info.
Please help.
Log_inn.php
<?php
session_start();
include'conn.php';
include'vars.php';
?>
<table width="100%" border="0" cellpadding="4">
<?php
if(!isset($msg)){
$memdesp = "";
}if(!isset($mem_dsp)){
$mem_dsp = "";
}
$sql = "SELECT * FROM message LIMIT 10";
$result = mysql_query($sql);
while ($row = mysql_fetch_row($result)){
$msg = $row[0];
$memdsp = "<tr>
<td WIDTH=400 colspan=2 align=left valign=top><p align=left> $row[0]</p></td>
</tr>";
if (!isset($mem_dsp)){
$mem_dsp = '';
}
$mem_dsp = $mem_dsp.$memdsp;
}
mysql_free_result($result)
print $mem_dsp;

php.net : http://fr3.php.net/include_once :
The include_once() statement includes and evaluates the specified file during the execution of the script. This is a behavior similar to the include() statement, with the only difference being that if the code from a file has already been included, it will not be included again. As the name suggests, it will be included just once.

Here's my vars.php
<?php
$name = ''; // Default value
if(isset($_POST['name'])){
$name = $_POST['name'];
}
$email = '';
if(isset($_POST['email']))
$email = $_POST['email'];
}
$username = '';
if(isset($_POST['username'
$username = $_POST['username'];
}
$pass = '';
if(isset($_POST['pass'])){
$pass = $_POST['pass'];
}
$Username = '';
if(isset($_POST['Username'
$Username = $_POST['Username'];
}
$Password = '';
if(isset($_POST['Password'
$Password = $_POST['Password'];
}
$text_input = '';
if(isset($_POST['text_inpu
$text_input = $_POST['text_input'];
}

and conn.php
<?php
$dbcon = mysql_connect("192.168.41.
if (!$dbcon){
echo 'Unable to connect';
echo mysql_error();
}
$mm = mysql_select_db("aikido", $dbcon);
if (!$mm){
echo 'Unable to connect to Chat Room Database';
}
?>
<?php
$name = ''; // Default value
if(isset($_POST['name'])){
$name = $_POST['name'];

$email = '';

$email = $_POST['email'];

$username = '';

$username = $_POST['username'];

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

$Username = '';
if(isset($_POST['Username'

Better would be:
$_SESSION['Username'] = $_POST['Username'];.

to add the smily ... I have no idea how to pass the value of a fom buttom .
still do not see where your populate your session values? for example for the name it should be :
Chat_test.php
<?php
session_start();
include 'conn.php';
include 'vars.php';
$_SESSION['Username'] = $Username;
?>
NB: uncomment your line //$_SESSION['Username'] = $Username; and put it after the includes
the variable $Username should be global, but if your doubting, try to do :
Chat_test.php
<?php
session_start();
include 'conn.php';
include 'vars.php';
global $Username;
$_SESSION['Username'] = $Username;
?
>
Chat_test.php
<?php
session_start();
include 'conn.php';
include 'vars.php';
$_SESSION['Username'] = $Username;
?>
NB: uncomment your line //$_SESSION['Username'] = $Username; and put it after the includes

Chat_test.php
<?php
session_start();
include 'conn.php';
include 'vars.php';
global $Username;

Any help with the fom buttons and text color? How will I tell the form to add a button value and change the text color?
Thanx
Thanx
to add smileys use php (no need for java to do this) preg_replace
exemple : $text = preg_replace("/:\)/i",$img
exemple : $text = preg_replace("/:\)/i",$img
ASKER
Please explain how I will use $text = preg_replace("/:\)/i",$img
same for text/button color use CSS in combination with switches/if statements and regular expressions if you need to replace something in the code
you put your html code in a variable, for example you call it text :
then you replace all ":)" ";)" etc etc in it by your smileys
ex:
$text = 'hello :)';
$img_happy = '<img src="smilies/happy.gif" alt="" >';
$text = preg_replace("/:\)/i",$img
echo $text;
then you replace all ":)" ";)" etc etc in it by your smileys
ex:
$text = 'hello :)';
$img_happy = '<img src="smilies/happy.gif" alt="" >';
$text = preg_replace("/:\)/i",$img
echo $text;
ASKER
Thanx!
you are welcome :)
