Code help

define "Doesn't allow access"

it just would let the user login

Such statements do not make any sense, you are assigning the value to the same variable again...
$_POST['user'] = $_POST['user'];
$_POST['passdef']= $_POST['passdef'];

Do you want to users to provide passdef or username and password? Use mysql_num_rows() (www.php.net/mysql_num_rows) to know if your sql query returned any records

$result = mysql_query("SELECT count(id) FROM users WHERE passdef='" . $_POST['passdef']. "'") or die("Couldn't query the user-database.");
 
$num = mysql_num_rows($result);
if ($num==0)
...
...

how about this

This is working fine but doesn't insert the values

<?PHP
 
require_once('info.php');
 
$user = mysql_real_escape_string($_POST['user']);
 
$pass = mysql_real_escape_string($_POST['pass']);
 
$result = mysql_query("SELECT user,pass FROM users WHERE pass='" . $pass. "'  OR (user='". $user."' AND pass='".$pass."')") or die("Couldn't query the user-database.");
 
$num = mysql_num_rows($result);
 
if (!$num) {
 
 
echo "<h4> <center><br><br>
<form action='$_SERVER[PHP_SELF]' method='post'>
UserName: <input type='text' name='user'><br><br>
Password : <input type='password' name='pass'><br>
 
<br><br>
<input type='submit' size='10' value='Login'>
</form></center></h4>";
 
}else {
 
        list($dbuser,$dbpass) = mysql_fetch_row($result);
        
        if($dbuser==$user && $dbpass==$pass) {
        
                echo "You entered a username & password";
        
        }else{
        
                echo "<h4> <center><br><br>
<form action='$_SERVER[PHP_SELF]' method='post'>
New PassWord: <input type='text' name='newpass'><br><br>
Confirm Password : <input type='password' name='confirmpass'><br>
 
<br><br>
<input type='submit' size='10' value='Login'>
</form></center></h4>";
 
if($_POST['newpass'] == $_POST['confirmpass'])
{
		$insertquery = "insert into user (user, pass) VALUES ('{$_POST['user']}','{$_POST['newpass']}')";
		$resultinsert = mysql_query($insertquery);
        
        }
		else {
		echo " your password didn't match";
		
}
 
 }
}
?>

Select allOpen in new window

Above code works but it put values in different rows
Thanks

>>but doesn't insert the values
Because you do not have the value for user. Print the insert query and you will see there is no value for user.

User provide $_POST['user'] in different form and $_POST['newpass'] in different.

you are right . how can I fix that

I just noticed that you hare asking the same question in 2 different threads...

If you want to allow user to update the password, then provide new password fields in the same form in which you are asking username and password.

And if you are trying to create a member area type thing, then sessions will be of your inetrest http://www.php.net/session.

Continued...
And on successful match, update the password.

Thank you for your response. I asked initially a different question but then as I was working with them, it turned it same question. My sincere apologies.

Now I looked into session before but I couldn't use it due to certain things

Is there anyway around so it will insert the username in the same as it is inserting the password in.

Thanks

Its too late here, will see your reply tomorrow..ohhh.. later in the day ;-)

wasifg thanks for the code ..a small proble,. It should only ask the user to update a new password if and only if the user provides a default password
thanks

ok thats fine. you have a good night. See you tomorrow
thanks

What do you mean by default password?

There is a default password 777, the user has to enter that in order for being able to enter the change the password.

Thanks
