Wordpress Jquery+scripts enqueue issue

Question

I'm having some issues in loading a custom jquery slider into a wordpress site I'm working on: I'm not super proficient with theme development but I'm studying hard and I spent lots of days trying with no result.

I'm using the beaver builder for the graphical aspect but I'd like to insert a content slider (which in the free version is not provided). I tried to use a ready jquery content slider called anyslider.

My issue is that I'm not sure I'm loading the jquery scripts properly: thi is how I edited the functions.php file of my child theme:

<?php

add_action( 'wp_enqueue_scripts' ,'enqueue_parent_theme_style' );

function enqueue_parent_theme_style() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );

if (!is_admin()) add_action("wp_enqueue_scripts", "my_jquery_enqueue", 11);

function my_jquery_enqueue() {
   wp_deregister_script('jquery');
   wp_register_script('jquery', "http" . ($_SERVER['SERVER_PORT'] == 443 ? "s" : "") . "://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js", false, null);
   wp_enqueue_script('jquery');

function add_my_script() {
  wp_enqueue_script(
    'anyslider',
    get_template_directory_uri() . '/js/jquery.anyslider.js', 
    array('jquery')
  );

  wp_enqueue_script(
    'anyslider_easing',
    get_template_directory_uri() . '/js/jquery.easing.1.3.js',
    array('jquery','anyslider')                     
  );
} 

add_action( 'wp_enqueue_scripts', 'add_my_script' );  

I tried to follow every tutorial I found by the book what am i doing wrong?

EDIT

I edited the functions.php file like this: now it's working, thanks everybody

<?php

add_action( 'wp_enqueue_scripts' ,'enqueue_parent_theme_style' );

function enqueue_parent_theme_style() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}


if( !is_admin() ){
    wp_deregister_script('jquery');
    wp_register_script('jquery', ("http://code.jquery.com/jquery-latest.min.js"), false, '');
    wp_enqueue_script('jquery');
}



add_action('wp_enqueue_scripts', 'mytheme_custom_scripts');

if (wp_script_is('jquery')) echo "<h1>IT WORKS!</h1>";

Answer 1

The enqueue_parent_theme_style() and my_jquery_enqueue() functions do not have closing brackets. Does the above code run?

Otherwise the code looks okay. Are running WordPress with WP_DEBUG set to true? https://codex.wordpress.org/Debugging_in_WordPress I use the following in my wp-config.php file:

if ($_SERVER['REMOTE_ADDR'] == '123.456.789.123') {
    define('WP_DEBUG', true);
    define('WP_DEBUG_LOG', true);
    define('WP_DEBUG_DISPLAY', false);
    @ini_set('display_errors', 0);
}
else {
    define('WP_DEBUG', false);
}
