Session Untuk Login Atau Sewaktu Dengannya

cade · June 29, 2007

biasa nye dlm php.ini setting akan discard sumer session yg hang upon closing the browser. So server akan assume user dah logout...aku nyer masalah kat atas x settle lagi la amin007. Session aku mcm di 'unset' bila aku navigate ke page lain...FYI, aku pakai windows XP, php 4.4.4 configured with IIS

when you're using session trans sid ENABLED, and you perform redirect such as Header( "Location..." ), redirected client will SURELY loose his session.
to avoid this, you can use a modified version of redirect function, like this:
<?php
function Redirect302( $location )
{
$sname = session_name();
$sid = session_id();
if( strlen( $sid ) < 1 )
{
Header( $location );
return;
}

if( isset( $_COOKIE[ $sname ] ) || strpos( $location, $sname."=".$sid ) !== false )
{
Header( $location );
return;
}
else
{
if( strpos( $location, "?" ) > 0 )
$separator = "&";
else
$separator = "?";
$fixed = $location . $separator . $sname."=".$sid;
Header( $fixed );
return;
}
}
?>
expamle:
Redirect302( "Location: /YourPage/index.php" );
the function performs common redirect if no session is active, and appends session "name=sid" to query string when session is already started, like PHP parser does when outputting your page.
hope, you'll find it useful.
yours:)

ini aku jpe kat php official sites...sesapa leh tolong translate

aku dah baca kat php.net pasal session ni

yang aku jumpa ialah

http://my2.php.net/manual/en/function.session-start.php

http://my2.php.net/manual/en/function.session-id.php

cade, kalau ko nak tahu, aku guna session ni untuk 2 aplikasi

1) nak login & kekalkan hingga logout

2) nak tahu sql selepas insert,update & delete

aku hanya daftar apa $_session[] yg aku nak,

lepas tu buat header('Location:link_papar.php?jadual=link&item=10')

ini kod sql

// hidupkan $_SESSION
$_SESSION['sql'] = $query;
$_SESSION['rekod'] = "Rekod Ditambah";
$_SESSION['jumlah'] = mysql_affected_rows();
header('Location:link_papar.php?jadual=link&item=10');

ni kod nak paparkan data dari database

<?
#####################
include "sesi.php"; #
#####################
?>
<html>
<head><title>View All [<?=$_GET[jadual];?>]</title></head>

<body>
<? 
echo "<fieldset><legend>SQL : ".$rekod.":".$jumlah."</legend>
<pre>SQL = {".$sql."}</pre></fieldset>\n";
$_SESSION['rekod'] = ""; $_SESSION['jumlah'] = "";

$myTable=$_GET[jadual];
if (!isset($_REQUEST['asing']) ) { 
$sql  = "SELECT * FROM ".$myTable." ORDER BY 1,3,4";}       
else {$sql = "SELECT * FROM ".$myTable." WHERE 
id_kategori_menu = '".$_REQUEST[id_kategori_menu]."' ";}

kalau ko orang perasan, aku tak guna session_start(); pun

aku letak kat dlm include "sesi.php";

kaedah yg sama juga aku guna untuk login juga.

ni contoh yg aku buat

https://amin007.org/penduduk/sirap/

kat sini, tiap2 fail aku letak include "sesi.php";

cuba ko orang masuk, username & password = user

ini ayat yg ko akan jumpa

Di bawah ini adalah link kepada sistem tersebut :
Peta Daerah Banci
Rangka BP
M3 - Penerangan Tentang Kawasan Peta Daerah Banci
L2A - Penyenaraian Tempat Kediaman (TK) Di Dalam Blok Penghitungan (BP)
L2B - Butir - butir Isi Rumah
SPDRB - Sistem Pangkalan Data Rangka Banci

kalau tak faham, .... tanya kat sini

setakat yg aku guna session jarang aku hilang data $_session[]

melainkan kalau masa dah tamat hehehe

jika guna kod yg aku pakai ni.

nak senang, ko paparkan nilai $_session[],

jadi ko akan tahu nilainya apa.

tapi kalau tiba2 hilang & masa ada lagi, tu .....
