You will never get a result as

$p

Dosent equals what is in the database. The password stored looks like a sha1 hash. So you need to hash the password with same encryption:

$p =$_POST['upass'];
$p = sha1($p);

Then search the database.

Jnerocorp · April 2, 2011

or you could also just do

$p = sha1($_POST['upass']);

TheSky · April 2, 2011

i was using it but i get same results

$p = sha1($_POST['upass']);

i get *FBF03E4A22BC2A25D0E1A41EC68C6DA but it cant read it on sh1 or md5 i get same hash even i dont use any, kinda strange

Jnerocorp · April 2, 2011

can you post the registrastion page code?

jamesjmann · April 2, 2011

In my opinion Your code iS poorly written/organized. I would use a nice switch statement to handle the script

TheSky · April 2, 2011

this is registration page

<?php 

if(isset($_POST['Submit'])){

//NEED TO CHECK IF FIELDS ARE FILLED IN

if( empty($_POST['name']) && (empty($_POST['email']))){

header("Location:Messages.php?msg=3"); 

exit();

}

if( empty($_POST['pw1']) && (empty($_POST['pw2']))){

header( "Location:Messages.php?msg=4" ); 

exit();

}

$name=$_POST['name'];

$email=$_POST['email'];
$NR=$_POST['NR'];


$pw1=$_POST['pw1'];

$pw2=$_POST['pw2'];


//password control
if("$pw1" !== "$pw2"  ){

header( "Location:Messages.php?msg=5" ); 

exit();

}

$ip = $_SERVER['REMOTE_ADDR'];



//connect to the db server , check if uname exist

include('config.php');

$query=("Select * from user where uname='$name'");

$result= mysql_query($query); 

$num=mysql_num_rows($result);

if ($num > 0) {

header( "Location:Messages.php?msg=6" ); 

exit();

}else{
//encrypt password
//$password0 = md5($_POST['pw1']);
//if username does not exist insert user details

$query=( "INSERT INTO user (uname, pw,email,NR,date_joined,ip,level) VALUES ('$name',password('$pw1'),'$email','$NR',NOW(),'$ip','Normal')");

if (@mysql_query ($query)) {

header("location:login.php?reg=1");

exit;

}

}

mysql_close();

}

Your INSERT query uses MySQL's PASSWORD() function, which it should not. Use an SHA1 hash both when you insert the password, and when you compare the form field to it upon login.

TheSky · April 2, 2011

So i did use for sending and geting password with SHA1 but should i use in database table pw ( varchar ) or other type anyway i got Length/Values1 ( 32 )

forgive me if im wrong im some kind beginer on mysql and php

Pikachu2000 · April 2, 2011

If you're going to use SHA1, make the field's data type CHAR(40).

Jnerocorp · April 2, 2011

change

$query=( "INSERT INTO user (uname, pw,email,NR,date_joined,ip,level) VALUES ('$name',password('$pw1'),'$email','$NR',NOW(),'$ip','Normal')");

to


$pw1 = md5($pw1);

$query=( "INSERT INTO user (uname, pw,email,NR,date_joined,ip,level) VALUES ('$name','$pw1','$email','$NR',NOW(),'$ip','Normal')");

in the comments it says its going to do an md5 encrtyption change md5 to sha1 if u want it to be sha1 encryption
