PHP Login System help please

[phfilly]

Hi guys!

I got a problem with my logging in system. I can connect to my database with the code:

session_start();
                        
                        include('header.html');
                        $page_title = 'Home Page';
                        
                        
                        $mail = $_POST['email'];
                        $password = $_POST['password'];
                        $msg ='';
                        
                        if(isset($mail,$password)){
                                $con = mysql_connect('127.0.0.1','root','');
                            
                                if(!$con)
                                {
                                    die('Could not connect: '.mysql_error());
                                }
                                else{
                                    echo "Connected!";
                                }
                        }       

$db_found = mysql_select_db("dbusers", $con);

Then I connect to the table and I want to retrieve the registered users details from the table "mytable" and then I want to greet the registered user with by his name.

$myMail = stripslashes($mail);
                            $mypassword = stripslashes($password);
                           
                            $sql ="SELECT * FROM mytable WHERE Email = '$myMail' AND Password='$mypassword'";
                            $result = mysql_query($sql);
                            
                            $sql2 ="SELECT Name FROM mytable WHERE Email = '$myMail' AND Password='$mypassword'";
$name = mysql_query($sql2);

No I run through the "array" to find the name according to the email and password

while($rows = mysql_fetch_row($result)){
                                if($rows['Name'] == $name ){
                                    echo "<h1>Welcome $name </h1>";
                                }
                                else{
                                    echo "No Name";
                                }
                            }

But the error states:

Notice: Undefined index: Name in C:\Program Files\EasyPHP-5.3.8.1\www\Login.php on line 46

Ok I understand it but the in my table in columns name is "Name" correctly spelled.

Its prob just something small...just need a fresh mind to help me :D

Sorry for the long post.

Kind Regards

Ok one thing I changed in the while loop the

while($rows = mysql_fetch_row($result)){

TO

while($rows = mysql_fetch_array($result)){

so the error is gone but still I can't retrieve the name of the database/table :/ it just gives me "No Name"

Yo philly!

try something like this:

$server = '127.0.0.1';
$user_name = 'root';
$password = '';
$database = 'yourdatabase name';

if(!mysql_connect('127.0.0.1','root',''))
{
   if(!mysql_connect('localhost', 'root', ''))
{
 	exit('Error: could not establish database connection');
}
if(!mysql_select_db($database))
{
 	exit('Error: could not select the database');
}

and remember to say

include "file.php"

in every file at the top in which there are contents that require a connection with your database.

[Joemeister]

This is now if you wish to connect to your database!

[phfilly]

My connection works to my database! It prints the "Connected" string so that is fine...this is not the problem

I can't retrieve the data from the table...although the connection is made and correctly spelled

why use a loop to find the user info? why not just grab that specific user's data from the table in the first query

$result=mysql_query("SELECT * FROM mytable WHERE 
Email = '".mysql_real_escape_string($myMail)."' AND 
Password='".mysql_real_escape_string($mypassword)."'") or die(mysql_error());
if (mysql_num_rows($result)==0){echo "user not found";}
else{
   $user=mysql_fetch_assoc($result);
   echo $user['Name'];
}

   echo $user['Name'];
}

Thank you!It works!!Didn't really know about the mysql_fetch_assoc function but sweet! And so you learn!

@evstevemd - I checked it out-and it's definitely what I was looking for-just a lot of video's though- I'm capped with my BW :/ but non the less Thanks
