wordpress http 500 error after adding custom jquery

Question

I have been attempting different methods of adding jquery to my site for a while now - and found that the best practice is to enqueue it in functions.php. Specifically i am trying to add a 'sticky' nav bar that snaps to the top of the page as the user scrolls down. However when i do this my site get a 500 error and I have to remove it to get the site back up and running.

It is obviously the functions.php code to enqueue the script or the script itself causing the problem - however i have not been able to identify which and of course why. (could there be an issue with how my server is set up? lack of resources/permissions ect?)

Here is my Functions.php extract:

    function verdigris_script() {
// register your script location, dependencies and version
   wp_register_script('custom_js',
   get_template_directory_uri() . '/js/scripts.js',
   array('jquery'),
   '1.0', true );

function scripts_enqueue() {
    //css
    wp_enqueue_style('bootstrap', get_template_directory_uri() . '/css/bootstrap.min.css', array(), 'all');
    wp_enqueue_style('customstyle', get_template_directory_uri() . '/css/verdigris-style.css', array(), 'all');
    //js
    wp_enqueue_script('jquery');
    wp_enqueue_script('bootstrapjs', get_template_directory_uri() . '/js/bootstrap.min.js', array(), true);
    wp_enqueue_script('custom_js');

}
add_action( 'wp_enqueue_scripts', 'verdigris_script');

and this is my script:

    jquery(function() {
  var $container = $('.container');
  var $b = $('body');
  $.waypoints.settings.scrollThrottle = 0;
  $container.waypoint({
    handler: function(e, d) {
      $b.toggleClass('sticky', d === 'down');
      e.preventDefault();
    }
  });
});

am asking if anyone can identify the issue.

Many thanks in advance.

Always check the server error logs to find out the reason behind a 500 error message. The error itself is too broad and covers a multitude of issues. — aynber

You can usually find the error message if you check error logs or turn on debugging in your wordpress settings, here is a question with a good answer in regards to debugging stackoverflow.com/questions/1080679/php-and-wordpress-debugging — Uberswe

you dont have to do this wp_enqueue_script('jquery'); wordpress ships with its own version of jquery — victor

You have an error in your PHP code.

You're unintentionally declaring a function inside another function and never closing it.

Remove:

function scripts_enqueue() {

Thank you. ^ this worked. I knew itd be something trivial i had missed.

Does this mean i don't need to add a new function when enqueueing after registering?

when writing PHP code, it is a good idea to check that it's valid PHP syntax before trying to run it. Any good IDE or editor will tell you this automatically and highlight the errors, which is why I always suggest using a decent editor, but you can also run php -l <filename> to get PHP to check for syntax errors without running the code.

@MoxieProxy You can register and enqueue a script within the same function. It's equally fine to register in one function and enqueue in another. Your error was down to a mistake in PHP. If you open a function you need to close it.
