form variables in php function not working

germanjulian

ahhhh this is so easy but i cant get it to work

i got a form with f_user and f_password which gets submitted into the login.php which doesnt work

Parse error: parse error, unexpected T_FUNCTION in c:\apache group\apache\htdocs\website\php\login.php on line 11

where to use " ' or ( or [ ????

 

$status = authenticate($_POST["f_user"],$_POST["f_pass"]) 

function authenticate(f_user,f_pass) 
{ 
include ("connect.php"); 

$query = "SELECT UserId from customers WHERE UserId = '$user' ANDPassword = '$pass'"; 

[CODE]

laserlight

it should be:

function authenticate($f_user, $f_pass)

scoppc

$status=authenticate($_POST['f_user'],$_POST['f_pass']);
function authenticate($user,$pass){
//codes here
}

inside your function, you should use $user and $pass to refer to the content of $POST['f_user'] and $POST['f_pass']

mhhhhh
doesnt work same error on the second line (urs). first of all shouldnt it read

$status=authenticate($_POST['f_user'],$_POST['f_pass'])

instead of

$status=authenticate($_POST['f_user'],$_POST['f_pass']) ;

without the ;

however the error is on the next line unexpected T_FUNCTION ?!

the

function authenticate($user,$pass)

bit the variables $user and $pass can be names to anything I want isnt it?

germanjulian

YEAH WORKS!

$user = ltrim(rtrim($POST['f_user']));
$pass = ltrim(rtrim($POST['f_pass']));

if(!authenticate($user, $pass)) {

echo "no user found";

} else {

//found user, continue with script!

}

function authenticate($the_user, $the_pass)
{
include('connect.php');

$the_user = addslashes($the_user);

// should be storing passwords in db in md5()
// should be doing md5() on pass

$query = "SELECT count(*)AS total FROM customers WHERE UserId = '" . $the_user . "' AND Password = '" . $the_pass . "'";

if (!$r = mysql_query($query)) {

die(mysql_error());

}

if (!$row = mysql_fetch_array($r)) {

return('0');

} else {

return($row['total']);

}
}
