Bootstrap slider not working

Question

I have a html bootstrap slider which works fine with captions and everything.I would like to integrate it into my Wp theme (my forst one, so total newbie).I found a code, which seems to helo, but it only shows the three pictures and nothing slides...if I hard code the slider, it works.I understand I can just leave it hard coded, but then it's not really WP ;) THANKS. Here is the code: functions.php - now complete file.

function load_stylesheets()
{

wp_register_style('style', get_template_directory_uri() . '/style.css', array(), 1,'all');

wp_enqueue_style('style');

wp_register_style('bootstrap', get_template_directory_uri() . '/bootstrap-4.1.3-dist/css/bootstrap.min.css', array(), 1,'all');

wp_enqueue_style('bootstrap');

wp_register_style('fixedcss', get_template_directory_uri() . '/css/fixed.css', array(), 1,'all');

wp_enqueue_style('fixedcss');

wp_register_style('custom', get_template_directory_uri() . '/custom.css', array(), 1,'all');

wp_enqueue_style('custom');

}

add_action('wp_enqueue_scripts', 'load_stylesheets');


//load scripts

function load_javascript()
{

wp_register_script('custom', get_template_directory_uri() . '/js/custom.js', 'jquery', 1, true);
wp_enqueue_script('custom');

wp_register_script('bootstrapjs', get_template_directory_uri() . '/bootstrap-4.1.3-dist/js/bootstrap.min.js',array('jquery'), 1 , true);
wp_enqueue_script('bootstrapjs');

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

Answer 1

You've tagged your question correctly with wp_enqueue_script but it doesn't appear in your code so you are probably missing the jQuery library and bootstrap by the looks of it.

Try adding the following:

add_action('wp_enqueue_scripts', 'wp_add_jquery');

function wp_add_jquery () {
    wp_register_script( 'my_jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js');
    // Add your other scripts here (bootstrap, etc.)

}

Answer 2

Check with bootstrap & Jquery dependency file enqueue.

You need to load your bootstrap style & Jquery by the action wp_enqueue_style and wp_enqueue_script.

Example: In functions.php

    function my_scripts() {

   wp_enqueue_style('bootstrap4', 'https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css');
wp_enqueue_script( 'boot1','https://code.jquery.com/jquery-3.3.1.slim.min.js', array( 'jquery' ),'',true );
wp_enqueue_script( 'boot2','https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js', array( 'jquery' ),'',true );
wp_enqueue_script( 'boot3','https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js', array( 'jquery' ),'',true );

}

add_action( 'wp_enqueue_scripts', 'my_scripts' );

Also in your custom js you need to put this $('.carousel').carousel();

Answer 3

I added

wp_deregister_script('jquery');

to my funcitons.php and now it works, I suppose there must have been a conflict with my enqueued jquery.
