Add taxonomy term code

Hi,

I found this code for adding a new term for a taxonomy from the front end.

<?php

// Check to see if correct form is being submitted, if so continue to process
if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) &&  $_POST['action'] == "new_term") {

    // Check to see if input field for new term is set
    if (isset ($_POST['term'])) {

        // If set, stores user input in variable
        $new_term =  $_POST['term'];

        // Function to handle inserting of new term into taxonomy
        wp_insert_term(

          // The term (user input)
          $new_term,

          // The club taxonomy
          'Club'        

        );

    } else { 

        // Else throw an error message
        echo 'Please enter a club name!';     

    }

}

?>

<form id="insert_term" name="insert_term" method="post" action=""> 

    <input type="text" value="" name="term" id="term" />
    <input type="submit" value="Add Club" id="submit" name="submit" />
    <input type="hidden" name="action" value="new_term" />

</form>

I need help working this into a page. How can I insert both PHP & HTML?

Thanks in advance!
