Password Protect This Post – Change text?

I found the solution here:

It was a while ago and probably an older version of WordPress but it may work. Give it a try.

Its not great though because it is a core files hack which is not a great solution.

Add the following to your Funtions.php file under your theme folder:

// Password Protected Page Message
function custom_password_form($form) {
  $subs = array(
    '#<p>This post is password protected. To view it please enter your password below:</p>#' => '<p>Change this for New Message.</p>',
    '#<form(.*?)>#' => '<form$1 class="passwordform">',
    '#<input(.*?)type="password"(.*?) />#' => '<input$1type="password"$2 class="text" />',
    '#<input(.*?)type="submit"(.*?) />#' => '<input$1type="submit"$2 class="button" />'
  );

  echo preg_replace(array_keys($subs), array_values($subs), $form);
}

add_filter('the_password_form', 'custom_password_form');
