Re: [RELEASE] PHP Login Tutorial / No Mysql / DarkCoder

very basic. should move to showcase

 

[Hammad]

Hmm...very useful for beginners like me in PHP. I actually learnt a lot from this, thanks!

Pretty basic, also if you're passing stuff like passwords through a form, NEVER use get it's very unsafe. Use post instead.

Also, you're coding style is sloppy, it'll make your brain explode on big projects.

This is how I would code it:

<form name='password' action="test1.php?" method="post">
Password: <input type="text" name="pass"><br />
<input type="submit" value="Go!">
<br /> </form>

<?php
$pass=$_POST['pass'];

if ($pass == "dark") {

      echo "Password Correct.";

}
?>

 

[foxx]

lol $_GET

 

[Hammad]

What's wrong with $_GET?

 

[foxx]

/page.php?pass=thisismypweveryonecankindaread

tis s mush betta, not like you need md5 when you're not saving it anywhere though.

$pass = md5(ahoj);
$post = md5($_POST['pass']);

if($pass == $post)
{
echo "ok";
}
else
{
echo "wrong password, you fail";
}

 

[Monsta.]

Foxx123, what does "ahoj" equal?

 

[foxx]

it's czech hello .. hm and when I think about it, $pass = md5("ahoj");

 

[Daney]

Ahoj Foxx

Also, there are better ways of doing this, sessions etc. but good to learn the basics.

 

[Hammad]

/page.php?pass=thisismypweveryonecankindaread

tis s mush betta, not like you need md5 when you're not saving it anywhere though.

$pass = md5(ahoj);
$post = md5($_POST['pass']);

if($pass == $post)
{
echo "ok";
}
else
{
echo "wrong password, you fail";
}

OK... but what's the

$pass = md5(ahoj);

there for?

 

[foxx]

That's the password, md5() is a php function which makes it encoded.

 

[Hammad]

But it says the password is 'pass'?

 

[foxx]

nope, it says that the password is "ahoj",
in that guide he did

if ($pass == "dark") {

where "dark" is the password, i've only "stored" that password in a variable..
in his guide it would be

$password = "dark";
if ($pass == $password) {

 

[Hammad]

Aaah, I didn't see that.

 

[Virtue~]

thanks dark.. Can use md5 or $post. But only other people the will see it are other people on the computer unless someonmess remote veiwing it.

 

[GunZha]

Thx a lot dude!

 

[danse]

That's the password, md5() is a php function which makes it encoded.

A little correction it's not encoding, cause md5 algorithm is one way, sayin other way, once you crypt ( scramble ) something with and md5 you won't decrypt it back, cause md5 is partly random and so far no one provided and inverse algorithm. And no brute force method does not count as a decryption cause always i can manage so complicated password that with brute force method you won't break it and your grand children still won't see the results.

}

Wouldn't it be:
Password:<input type="text" name="password" />

 

[Pieman]

No. In PHP or any coding language for that matter it's important to make your code as compact as possible while maintaining readability. That's why you should always abbreviate words if possible.

Also, notice how I called the form "Pass" and that I use $_POST['pass'] to get the contents of the form.
