Hi, I'm trying to make a form sticky but when I display it on the web I get a blank page. I'm following the example given in my PHP book I'm wondering if there 's an error in the book because it has 2 closing form tags which I didn't think was right. I'm going to paste the code and attach the page that has the example I'm following.
For some reason it 's not uploading the example. Are pdfs allowed?

CODE

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<?php
    $errors=array();
    if(isset($_POST['submit'])){
        validate_input(); //checks for empty fields
        if(count($errors) !=0){
            display_form();
        }
        else {
            display_form();
        }
    }
    function validate_input(){
        global $errors;
        if($_POST["name"]  == ""){
            $errors['name']="<font color='red'>
            please enter your name </font>";
        }
    }
   function display_form(){
          global $errors;
?>
<form action="" method="post">
    Name:  <input name="name" type="text" size="10" maxlength="10" value = "<?php echo $_POST[name]; ?>"/>
    <br />  
    <?php echo $errors['name']; ?>
<br />  
    Email:  <input name="email" type="text" size="15" maxlength="30" /><br />  
<input name="submit " type="submit" value="submit " />
</form>
<?php
   }
?>
</body>
</html>

There are several errors in the example that you should be able to spot yourself. If not, you're moving on too fast with the book...
