takde la....

it's just that kalau nak produktif dalam PHP, extending popular projects or working with frameworks, tak boleh lari dari design pattern.

paling tidak akan jumpa MVC dan Factory pattern.

Kalau tak faham pattern, memang pening la nak faham kod orang.

<?php require_once('Connections/pendaftaran.php'); ?>
<?php
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
$theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO profil (nama, ic, kursus, jantina, umur, alamat, status) VALUES (%s, %s, %s, %s, %s, %s, %s)",
GetSQLValueString($_POST['nama'], "text"),
GetSQLValueString($_POST['ic'], "text"),
GetSQLValueString($_POST['kursus'], "text"),
GetSQLValueString($_POST['jantina'], "text"),
GetSQLValueString($_POST['umur'], "text"),
GetSQLValueString($_POST['alamat'], "text"),
GetSQLValueString($_POST['status'], "text"));

mysql_select_db($database_pendaftaran, $pendaftaran);
$Result1 = mysql_query($insertSQL, $pendaftaran) or die(mysql_error());

$insertGoTo = "index.php";
if (isset($_SERVER['QUERY_STRING'])) {
$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $insertGoTo));
}

mysql_select_db($database_pendaftaran, $pendaftaran);
$query_rsdaftar = "SELECT profil.id_profil, profil.nama, profil.ic, profil.no_matriks, profil.kursus, profil.jantina, profil.umur, profil.email, profil.no_tel, profil.no_telefon, profil.alamat, profil.status FROM profil";

yeke..abis tu nk pilih ape ek dkat prnyataan SQL tuh..??:-?
Click to expand...

ni biar aku tolong, takdela hebat , tapi ada la sikit ilmu di dada

actually form yang bro buat tu every time dia load, dia akan display data dalam form kan .

itu bermaksud bro dah letak sql statement dalam page yang sama. better kalau bro jangan letak sql statement tu dalam page form masukkan data tu.

buat satu page kosong yang page form tu akan redirect ke page kosong tu dan dalam page kosong tu letakkan koding sql untuk insert data .

apabila selesai insert data redirect balik page kosong tu ke page yang lain (contohnya page notification). so masalah data akan di displaykan dalam form tu takkan berlaku lagi

so kronologi perjalanan proses tu
1. masukkan data
2. tekan submit
3. redirect ke page kosong(empty) dan berlaku proses insert data
4. dari page kosong tu akan redirect ke page seterusnya (contoh notification page)

and ingin diberitahu yang bro takkan nampak page kosong tu sebab bila bro tekan submit, pertukaran page dari page form -> notification page berlaku dengan cepat :). page kosong tu sekadar controller je untuk bro letakkan sql insert code :)

btw terima kasih otai2..
betul gak tu tuan,,tp saya dah jumpe cara lain..pernyataan SQL mesti SELECT dan WHERE..so masalah form ni da selesai..pada pendapat sy klau satu page pon tkpe..tp klau tknk pening kepala dan utk aspek kekemasan kod..buat page berasingan..:)
