create a users table, with fields:
userid primary auto increment
username
password
type
and what ever else you may need to be in the user table. you could tell the difference between the users by their “type”
so save admin type as 1 and everyone else who registers would be type two. so on the registration page when you insert data their type would be 2.
next you need to use sessions so on login page use your form for login, validate users info.
simple example
[php]
<?php
if(isset($_POST["username"])){
$username = strip_tags($_POST["username"]);
$username = mysql_escape_string($username);
$password = strip_tags($_POST["password"]);
$password =mysql_escape_string($password);
$sql="SELECT id,username,type FROM admin WHERE username='".$username."' AND password='$password'";
$res=mysql_query($sql) or die("Error :
".mysql_Error());
if(mysql_num_rows($res)==0){
}else{
$row=mysql_fetch_assoc($res);
$_SESSION["id"] = $row["id"];
$_SESSION["name"]= $row["username"];
$_SESSION["type"]= $row["type"];
header("Location:loggedin.php");
}
}else{
$username = "";
$password = "";
echo"Username and/or password was not located! So get outta here :D ! ");
}
?>
<form method="post" action="login.php">
<table>
<tr>
<td class="side">Name</td>
<td><input type="text" name="username" value="'.$username.'"></td>
</tr>
<tr>
<td class="side">Password</td>
<td><input type="password" name="password" value="'.$password.'"></td>
</tr>
<tr>
<td>
<input type="submit" value="Login" style="width:100px;">
</td>
</tr>
</table>
</form>
[/php]
now the tricky part is on each of your pages you HAVE to have this on the first line of code
[php]session_start();
[/php]
if you want to keep non admins from an entire page do something like this at the top of the page
[php]
session_start();
if($_SESSION[“type”]!=1)){echo"<meta http-equiv=refresh content=0;url=login.php> ";}
[/php]
now if you want to just show different content to an admin user you can do something like
[php]
if($_SESSION[“type”]==1)){echo"
admin content
";
}
[/php]
again this is a real simple solution you could create header.php and use a user class and get all fancy but for the most part this should work ok!!!
