Log in page

[tlakso]

Hi,

trying to create a simple login page using php and a post form.

The following requirement holds,
1. there should NOT be any DB.
2. One user and one password is enough (yeah, said it was a simple
one...)

Tried with a function check_user() in a lib php-file, and a post form
in the login page. Code as follow:

<?php

function check_user(){
global $userfield, $pwdfield;

if( strcmp($_POST[$userfield],"user") == 0 ) {

if( strcmp($_POST[$pwdfield],"pwd") == 0 ) {
// Correct user
echo("correctdi r/album.htm");
}
else {
// Wrong pwd
echo("../somdir/default.htm");
}
else {
// wrong user
echo("../otherdir/default.htm");
}
}

}
?>

and the login page for is:
<?PHP
require('../somelib/login_lib.php') ;
?>

....
<form name="form1" method="post" action="<?php check_user();?> ">
<input type="text" name="userfield " >
<input type="password" name="pwdfield" >
<input type="submit" name="Log in" value="Log in">
</form>

....

Can't get it to work. Any good idea to resolve this? Any other more
brilliant solution instead of this?

br,
Magnus

You could do this:

if (!isset($_SESSI ON["pasword"])){
// generate a password, store it to above place and mail it to yourself
} else {
// output form/validate form when submited
}

Certainly you have to learn PHP. Buy some good books or Google
for PHP articles.... I'll try to pointout your mistakes...

Try $_POST['userfield']

Basci debugging trick: Run your PHP code on a webserver and
"view source" of the html page to verify.

It's because, you're trying to get the values before POST.

You can call a function, but not like JS. Obviously you have to
learn PHP.... If you know HTML, "view html source" of your PHP code.
