WordPress Default Search is Not cool. we are going to create WordPress Ajax Search without plugin that will look something like this.

WordPress Ajax Search without plugin

First We need to Create an input Field so users can search. Put it anywhere page template, single.php, archive.php, index.php, page.php, or anywhere you want to show search fieldSearch page

<div class="search_bar">
    <form action="/" method="get" autocomplete="off">
        <input type="text" name="s" placeholder="Search Code..." id="keyword" class="input_search" onkeyup="fetch()">
    <div class="search_result" id="datafetch">
            <li>Please wait..</li>


Main code for WordPress Ajax Search without plugin

Now put below code to functions.php On the post query you can customize your html as you want. This code will interact with HTML to achieve our goal to create wp Ajax Search without plugin.functions.php

 Ajax Search
// add the ajax fetch js
add_action( 'wp_footer', 'ajax_fetch' );
function ajax_fetch() {
<script type="text/javascript">
function fetch(){

        url: '<?php echo admin_url('admin-ajax.php'); ?>',
        type: 'post',
        data: { action: 'data_fetch', keyword: jQuery('#keyword').val() },
        success: function(data) {
            jQuery('#datafetch').html( data );



// the ajax function
add_action('wp_ajax_data_fetch' , 'data_fetch');
function data_fetch(){

    $the_query = new WP_Query( array( 'posts_per_page' => -1, 's' => esc_attr( $_POST['keyword'] ), 'post_type' => array('page','post') ) );
    if( $the_query->have_posts() ) :
        echo '<ul>';
        while( $the_query->have_posts() ): $the_query->the_post(); ?>

            <li><a href="<?php echo esc_url( post_permalink() ); ?>"><?php the_title();?></a></li>

        <?php endwhile;
       echo '</ul>';



Ajax Search for Custom post type

This code will be show result from page & post but if you want you can activate if for your wp custom post type as well. Simply you need to change ‘post_type’ => array(‘page’,’post’) to ‘post_type’ => array(‘your_custom_post_type’)

If search not work use this code [Most of the time not need ]only if custom post type not show in search result

 * This function modifies the main WordPress query to include an array of 
 * post types instead of the default 'post' post type.
 * @param object $query The main WordPress query.
function mukto_post_type_include( $query ) {
    if ( $query->is_main_query() && $query->is_search() && ! is_admin() ) {
        $query->set( 'post_type', array( 'post', 'page', 'custom_post_type' ) );
add_action( 'pre_get_posts', 'mukto_post_type_include' );
