@NogDogNov 28.2009 — The parameter for empty() must be a variable, not a function call. How about:
[code=php]
if(trim($_POST['username']) !== '');
[/code]

@ServauxauthorNov 28.2009 — Thanks NogDog...seems like I should have posted the rest of the code...I made that change and then I had syntax errors on three lines

Here is the orignal code in its entirety,

if(!empty(trim($_POST['username']))
&& !empty(trim($_POST['email']))) {

// Store escaped $_POST values in variables
$uname = htmlentities($_POST['username']);
$email = htmlentities($_POST['email']);

$_SESSION['username'] = $uname;

echo "Thanks for registering! <br />",
"Username: $uname <br />",
"Email: $email <br />";

}

else {
echo "Please fill out both fields! <br />";

}
}


else {
?>

it shows no erros until I check it in a browser and that when I get the fatal error

@NogDogNov 28.2009 — Please make use of this forum's [noparse][code=php]...[/code][/noparse] tags when posting PHP code samples: it makes life much easier on those who might want to help.

The opening if condition would need to be something like:
[code=php]
if(trim($_POST['username']) !== '' && trim($_POST['email']) !== '') {
[/code]
As to the rest, the curly braces do not balance out, but I'm guessing that may be due to not having all the code here, so I don't know if it's a problem or not.

@ServauxauthorNov 28.2009 — Hi NogDog thanks for your help I have implemented the changes and receive new syntax errors. configuring some of the curly braces only generated more erros starting with $uname and my else statement above the echo"please fill out both fields!"

Here is the code
[code=php] <?php

// Initialize session data
session_start();

/*
* If the user is already registered, display a
* message letting them know.
*/
if(isset($_SESSION['username'])) {
echo "You're already registered as $_SESSION[username].";
}

// Checks if the form was submitted
else if($_SERVER['REQUEST_METHOD'] == 'POST') {


}
if(trim($_POST['username']) !== ''
&& (trim($_POST['email']) !== '') {

// Store escaped $_POST values in variables
$uname = htmlentities($_POST['username']);
$email = htmlentities($_POST['email']);

$_SESSION['username'] = $uname;

echo "Thanks for registering! <br />",
"Username: $uname <br />",
"Email: $email <br />";

}
/*
* If the user did not fill out both fields, display
* a message letting them know that both fields are
* required for registration.
*/
else {
echo "Please fill out both fields! <br />";
}
}

// If the form was not submitted, displays the form HTML
else {

? [/code]

Success!
