spudnic072 on "Login Form Honey Pot"

So ive been trying to add a honey pot to my Wordpress Login, but its not working how I think it should.

I want to the login to redirect when the login form is filled out and there is any text in the Honey Pot form field.

This is how I am trying to add the form field and handle the form:

//LOGIN HONEYPOT
    add_action('login_form','myLogin_honeypot_form');
    function myLogin_honeypot_form (){
        $body = ( isset( $_POST['body'] ) ) ? $_POST['body']: '';
        ?>
        <p id="notTher">
            <label for="body"><?php _e('If you can see the below box, do not input any text. This is a test.','mydomain') ?><br />
            <input type="text" name="body" id="body" class="input" value="<?php echo esc_attr(stripslashes($body)); ?>" size="25" /></label>
        </p>
        <?php
    }

	function myLogin_HoneyPot_Error(){
	if($_POST['body'] != null){
			wp_redirect( site_url().'/wp-login.php' );
		}
	}
	add_filter('login_form','myLogin_HoneyPot_Error');

The new field shows fine, and it redirects properly BUT only if an invalid username is password is entered, if a valid user name and password is entered, the form logs the user in, But i want it to redirect before processing the login and password fields so that the user will not be logged in.

Thanks.
