function html_form_code() {
 echo '<form action="' . esc_url( $_SERVER['REQUEST_URI'] ) . '"

method="post">';
 echo '<p>';
 echo 'Your Name (required) <br/>';
 echo '<input type="text" name="cf-name" pattern="[a-zA-Z0-9 ]+"

value="' . ( isset( $_POST["cf-name"] ) ? 

esc_attr( $_POST["cf-name"] ) : '' )

 . '" size="40" />';
 echo '</p>';
 echo '<p>';
 echo 'Your Email (required) <br/>';
 echo '<input type="email" name="cf-email"

value="' . ( isset( $_POST["cf-email"] ) ? 

esc_attr( $_POST["cf-email"] ) : '' ) . '" size="40" />';
 echo '</p>';
 echo '<p>';
 echo 'Subject (required) <br/>';
 echo '<input type="text" name="cf-subject" pattern="[a-zA-Z ]+"

 value="' . ( isset( $_POST["cf-subject"] ) ?

esc_attr( $_POST["cf-subject"] )

 : '' ) . '" size="40" />';
 echo '</p>';
 echo '<p>';
 echo 'Your Message (required) <br/>';
 echo '<textarea rows="10" cols="35" name="cf-message">' .

( isset( $_POST["cf-message"] ) ?

_attr( $_POST["cf-message"] ) : '' )

  . '</textarea>';
 echo '</p>';
 echo '<p><input type="submit" name="cf-submitted"

value="Send"></p>';
 echo '</form>';
}

function deliver_mail() {

 // if the submit button is clicked, send the email
 if ( isset( $_POST['cf-submitted'] ) ) {

  // sanitize form values
  $name    = sanitize_text_field( $_POST["cf-name"] );
  $email   = sanitize_email( $_POST["cf-email"] );
  $subject = sanitize_text_field( $_POST["cf-subject"] );
  $message = esc_textarea( $_POST["cf-message"] );

  // get the blog administrator's email address
  $to = get_option( 'admin_email' );

  $headers = "From: $name <$email>" . "\r\n";

 
  if ( wp_mail( $to, $subject, $message, $headers ) ) {
   echo '<div>';
   echo '<p>Thanks for contacting me, expect a

 response soon.</p>';
   echo '</div>';
  } else {
   echo 'An unexpected error occurred';
  }
 }
}

function cf_shortcode() {
 ob_start();
 deliver_mail();
 html_form_code();

 return ob_get_clean();
}

add_shortcode( 'sitepoint_contact_form', 'cf_shortcode' );
?>
