Create Slide Show In WordPress

Slide show make your website look more attractive. There are many way to make slide show in WordPress by write the code or use the plugin. In this post I show you how to create slide show by using post featured image in WordPress without using plugin. You can read this tutorial how to enable post featured image. The slide show static code I got from codepen.

Create slide show

I put code on theme’s header.php file. You can put the code slide on wherever you like to show. Follow the code below, if you have any question please comment on the box below.

div id="slider">
<a href="#" class="control_next">>></a>
<a href="#" class="control_prev"><</a>
<?php $the_query = new WP_Query( ‘showposts=-1’ ); ?>
<?php while ( $the_query -> have_posts() ) : $the_query -> the_post(); ?>
<li><?php the_post_thumbnail(); ?></li>
<?php endwhile; ?>

Add JavaScript

I just customize JavaScript to make the slide show auto play.

[code lang=”js”]

jQuery(document).ready(function ($) {
setInterval(function () {
}, 3000);

var slideCount = $(‘#slider ul li’).length;
var slideWidth = $(‘#slider ul li’).width();
var slideHeight = $(‘#slider ul li’).height();
var sliderUlWidth = slideCount * slideWidth;

$(‘#slider’).css({ width: slideWidth, height: slideHeight });

$(‘#slider ul’).css({ width: sliderUlWidth, marginLeft: – slideWidth });

$(‘#slider ul li:last-child’).prependTo(‘#slider ul’);

function moveLeft() {
$(‘#slider ul’).animate({
left: + slideWidth
}, 200, function () {
$(‘#slider ul li:last-child’).prependTo(‘#slider ul’);
$(‘#slider ul’).css(‘left’, ”);

function moveRight() {
$(‘#slider ul’).animate({
left: – slideWidth
}, 200, function () {
$(‘#slider ul li:first-child’).appendTo(‘#slider ul’);
$(‘#slider ul’).css(‘left’, ”);

$(‘a.control_prev’).click(function () {

$(‘a.control_next’).click(function () {
