hi,
I am creating a form for user to update their details which is saved in the database. So far i can show their details in the form where i have a submit button but the updating part doesnt work(it doesnt update at all). here is the code:
<html>
<?php
session_start();
$host="localhost"; // Host name
$username="user"; // Mysql username
$password="123456"; // Mysql password
$db_name="db"; // Database name
$tbl_name="member"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$username = $_SESSION['myusername'];
if(!isset($_SESSION['myusername']))
{
header("location: main_login.php");
}
else
{
$query=" SELECT * FROM $tbl_name WHERE LoginName='$username'";
$result=mysql_query($query);
$num=mysql_numrows($result);
mysql_close();
$i=0;
while ($i < $num) {
$phone=mysql_result($result,$i,"telephone");
$add=mysql_result($result,$i,"address");
$town=mysql_result($result,$i,"town");
$email=mysql_result($result,$i,"email");
$city=mysql_result($result,$i,"city");
$postcode=mysql_result($result,$i,"postcode");
++$i;
}
$u_phone=$_POST['phone'];
$u_add=$_POST['add'];
$u_town=$_POST['town'];
$u_city=$_POST['city'];
$u_postcode=$_POST['postcode'];
$u_email=$_POST['email'];
$query1="UPDATE $tbl_name SET memberNo = NULL, LoginName=NULL, title=NULL, firstName=NULL, lastName=NULL, gender= NULL, address='$u_add', town='$u_town', city='$u_city', postcode='$u_postcode', telephone='$u_phone', email='$u_email', mshipType = NULL";
mysql_query($query1);
echo "Record Updated";
mysql_close();
}
?>
<form action="changedetails.php" method="post">
<table>
