what's up, im quite new to this so wondering if you guys can help me out.

i was wondering how do i use php to check that a username and password are correct?

i was thinking about using this $checkusername = strpos($username, $login);
but dont know how to progress from there


thanks :)

you only need to check if the password(and username if you want but that's not necessary) is the same as what it should be, if so you can print out the page or else show an error. Do you have any code so far?

[gwopboi]

he is the code i've got so far:

PHP:

<?php

$password = "test"; 

$pass= $_POST["pass"];

$checkpassword = strpos ($password, $pass);


if ($checkpassword === TRUE) {

    echo  "correct password"; }

    

else {

   

}

?>

it says wrong password when i run it..(btw just wrote 'correct password' there now just to chck but if correct i want it to go to another page, not to sure how to do that yet)

so basically i want it to check both password and user and if correct redirect to another page


thanks again!

why aren't you just doing:

if ($password == $pass)

[gwopboi]

thanks

Why don't you just check if the password is equal?

if ($_POST['pass'] == "1234" && $_POST['user'] == "admin"){

}else{

}

Didn't notice that last reply, check all your variables, make sure everything is all dandy and clean

without the code i can't really help :p

Your PHP code doesn't even seem to have 15 lines, can you post your current PHP code.

[gwopboi]

yes! thanks that did the trick!

[brokenbylaw]

you think about beefing up your security? try the hash function

[COLOR=#000000][COLOR=#007700][/COLOR][COLOR=#0000BB]hash[/COLOR][COLOR=#007700]([/COLOR][COLOR=#DD0000]'whirlpool'[/COLOR][COLOR=#007700], [/COLOR][COLOR=#DD0000]'The quick brown fox jumped over the lazy dog.'[/COLOR][COLOR=#007700]);[/COLOR][/COLOR]

you can use ripemd5, whirlpool, md5, sha512 look at the php docs for a complete list :)

now it works, so if the IF statement is true and i want to redirect to another page ...how will i go about doing it?

redirect in php would be through the header function

header('location:http://www.google.com');
