THe first problem I have in my code is the login ..

$sql = "SELECT * FROM register_info where user_name = ".$user_name." && password = ".$password." ";
         $result = mysql_query($sql)or die ("could Not execute query $sql");

     if (mysql_num_rows($result) == 0){
     redirect("fail_msg.htm");

     exit;

     }

     echo "<table>
     <tr>
     <td width = 50><b><font size=4 color=D70056 >Welcome</font></b></td>
     <td width = 200> <b><font size=3 color=ff0000 > ".$row["user_name"]."</font></b></td>
     <tr>
     <table>

     ";
     

This is my code and when I try to login by the username and the password

it gives me an error >>>> (Parse error: syntax error, unexpected )..

I don't know what is the wrong in this code 🙁

Can you help me, please?

I get no PHP parse errors in that piece of code, but I can see that the SQL will not be correct unless you quote the values. Also, they should be escaped to prevent SQL injection attacks (unless you've already escaped them earlier in the script?):

$sql = "SELECT * FROM register_info where user_name = '" .
       mysql_real_escape_string($user_name) . "'  && password = '" .
       mysql_real_escape_string($password) . "'";

Sorry, but I still have the error and it give me that the error in the line which i don't have.. (ex. i have 45 line only and the error in the line 46 >__< ) !!!

That means the file ended but PHP expected something more (a long thread on exactly this error message can be found here; usually it is more helpful to post the exact error message than posting a rough sketch of it.)

You have a { that is missing its matching }, or a string that hasn't been closed, or something else is missing that should be there.

the login is running with me now, but it check the user name only,
the code doesn't check the password

if I write the correct name with wrong password, it will enter me to the account >__<

and it give me this error

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\AppServ\www\job\login_engine.php:12) in C:\AppServ\www\job\login_engine.php on line 33

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\AppServ\www\job\login_engine.php:12) in C:\AppServ\www\job\login_engine.php on line 33

This is the code where it gives the error

session_start();

     $_SESSION['user_name']= $user_name;
     $_SESSION['password']= $password;

     $row=@mysql_fetch_array($result);

     echo "<table>
     <tr>
     <td width = 50><b><font size=4 color=D70056 >Welcome</font></b></td>
     <td width = 200> <b><font size=3 color=ff0000 > ".$row["user_name"]."</font></b></td>
     <tr>
     <table>
     ";

What Can I do 🙁

[Weedpacket]

This is another very common mistake (search the forums for "headers already sent" to give you an idea).

You can't do things that involve setting headers (functions like [man]header[/man], [man]session_start[/man], and [man]setcookie[/man]) if you have already started sending the content of your page (on line 12 of login_engine.php). You might as well make session_start() the very first thing you do.
