404 Error after login

[alphasil]

Hi

 

I'm getting this error but i'm sure the file is there, this is my code where i'm having this problem

elseif($_POST["page"] == "users_login") 
	{
		$user_utilizador = trim(strip_tags($_POST['email']));
		$user_password = trim(strip_tags($_POST['passwd']));
		$encrypted_md5_password = md5($user_password);
		$validate_user_information = mysql_query("select * from `utilizador` where `utilizador` = '".mysql_real_escape_string($user_utilizador)."' and `password` = '".mysql_real_escape_string($encrypted_md5_password)."'");
		echo $validate_user_information;
		if(mysql_num_rows($validate_user_information) == 1)
		{
			$get_user_information = mysql_fetch_array($validate_user_information);
			$_SESSION["VALID_USER_ID"] = $user_utilizador;
			$_SESSION["USER_FULLNAME"] = strip_tags($get_user_information["nome"]);
			echo 'index.php?uid='.$_SESSION["USER_FULLNAME"].'&';
			echo 'login_process_completed_successfully=yes';
		}
		else
		{
			echo '<br><div class="info">Desculpe, a informação fornecida está errada. Corrije-a por favor. Obrigado.</div><br>';
		}
	}

So after the login process it should open the index.php 

I have try with

header(Location: index,php) and the details are displayed in the same page as the login...

 

any help please?

Thanks

Do you have php error checking turned on (my sign.)? It might tell you that your header was rejected. An echo of the url is not going to do anything for you.

Thank you for your help

 

Yes i have error display but there is error right now, i don't have the 404 error but another issue

I put the header and now the login page and the index page are displayed at same time after login. Why the login page not close? 

elseif($_POST["page"] == "users_login") 
	{
		$user_utilizador = trim(strip_tags($_POST['email']));
		$user_password = trim(strip_tags($_POST['passwd']));
		$encrypted_md5_password = md5($user_password);
		$validate_user_information = mysql_query("select * from `utilizador` where `utilizador` = '".mysql_real_escape_string($user_utilizador)."' and `password` = '".mysql_real_escape_string($encrypted_md5_password)."'");
		if(mysql_num_rows($validate_user_information) == 1)
		{
			$get_user_information = mysql_fetch_array($validate_user_information);
			$user_nome = $get_user_information["nome"];
			$_SESSION["VALID_USER_ID"] = $user_utilizador;
			$_SESSION["USER_FULLNAME"] = $user_nome;
			header("Location: index.php");
		}
		else
		{
			echo '<br><div class="info">Desculpe, a informação fornecida está errada. Corrije-a por favor. Obrigado.</div><br>';
		}
	}

You should place a exit() call immediately after header(), otherwise the rest of the script continues processing.

 

Also, md5 is not encryption, nor is it safe. Please read this: http://jeremykendall.net/2014/01/04/php-password-hashing-a-dead-simple-implementation/

 

And you should not be using the mysql functions -- they will being going away in a future version of PHP -- but rather using mysqli or PDO along with prepared statements.

Thank you

 

Done...about the md5 right now i leave it this way...it is just a test.

 

Thanks

[ginerjm]

Why would you apply a function to your hashed password value? Makes no sense.

Also, might consider using a different hashing method. Md5() so outdated and EXTREMELY vulnerable.

Yes i know that but it just a small webite to my school, just to put some records about activities.

 

Many thanks to all
