What happens if you get rid of the function? As currently you are not calling it anyway.
Code:
<?php
session_start();
echo'
<div id="loginform">
<form action="index.php" method="post">
<p>Please enter your name to continue:</p>
<label for="name">Name:</label>
<input type="text" name="name" id="name" />
<input type="submit" name="enter" id="enter" value="Enter" />
</form>
</div>
';
if(isset($_POST['enter'])){
if($_POST['name'] != ""){
$_SESSION['name'] = stripslashes(htmlspecialchars($_POST['name']));
}
else{
echo '<span class="error">Please type in a name</span>';
}
}
?>
Alternatively you could try it without the echo statement, and as clean HTML.
Code:
<?php
session_start();
?>
<div id="loginform">
<form action="index.php" method="post">
<p>Please enter your name to continue:</p>
<label for="name">Name:</label>
<input type="text" name="name" id="name" />
<input type="submit" name="enter" id="enter" value="Enter" />
</form>
</div>
<?php
if(isset($_POST['enter'])){
if($_POST['name'] != ""){
$_SESSION['name'] = stripslashes(htmlspecialchars($_POST['name']));
}
else{
echo '<span class="error">Please type in a name</span>';
}
}
?>
