hmm... how do you get the username and password, from a mysql database?

 

if yes, then you open a connection to the database and check if the username exists, if it does you check if the password is equal to that users password in the database.

 

If you just want it simpel it aint that hard to code.

[rajivgonsalves]

well you have to tell us what your validating against... a database... a text file... more info is required

Sounds like you don't actually know PHP at all, and are therefore not looking for help with a script you have actually written, but in fact looking for someone to write you a script.

You don't have the basic knowledge. As Ive suggested to your ealier, there is a free book in my signiture that will get you started. getting us to write scipts for you is simply not how it works. This forum is for help with problems in your own code.

 

if you have code with problems, post it, otherwise your going to need to look at some tutorials to get the basics down.

So i need to put the code here

Ok

Here is the code which i used

<?php 
$strErrorMsg = ""; 
if (isset($_POST['submit'])) 
{ 
     if (empty($_POST['username'])) 
     { 
               $strErrorMsg .= "Username not entered"; 
     } 

     if (!empty($_POST['username']) && (!strcmp($_POST['username'])=='jimmy'))) 
     { 
               $strErrorMsg .= "Username is incorrect"; 
     }
     if (empty($_POST['password'])) 
     { 
               $strErrorMsg .= "Password not entered"; 
     } 

if(!empty($_POST['password']) && (!strcmp($_POST['password'])=='123456'))) 
     { 
               $strErrorMsg .= "Password is incorrect"; 
     }

 ?>

{ 
     if (empty($_POST['username'])) 
     { 
               $strErrorMsg .= "Username not entered"; 
     }

     // kind of useless to say !empty($_POST['username']) because you know it's not
     // empty since it passed the first IF statement. And just say
     // !preg_match("/jimmy/i",$_POST['username'])
     if (!empty($_POST['username']) && (!strcmp($_POST['username'])=='jimmy'))) 
     { 
               $strErrorMsg .= "Username is incorrect"; 
     }
     if (empty($_POST['password'])) 
     { 
               $strErrorMsg .= "Password not entered"; 
     } 

// again, you know $_POST['password'] is NOT empty here.
// And say: $_POST['password'] != '123456'
if(!empty($_POST['password']) && (!strcmp($_POST['password'])=='123456'))) 
     { 
               $strErrorMsg .= "Password is incorrect"; 
     }

 ?>

That is dear I say very ineffective. You're missing something at the end. All your code does so far is check if there are any errors. What if there isn't? What are you going to do then?

First, I really want you to listen to what thorpe said. Read up on basics. If you don't know how to even start on what you just told me, then you really need to learn them. Having us guide you through every letter, word and line isn't going to help you in the long run.

 

So use header(). For something like this, you probably want to use $_SESSION or $_COOKIE to store the login info so that you can check if the user is logged in. Otherwise, people can just go to the next page without logging in.
