How to Make a WordPress Settings Autocomplete Field Using Ajax

Please put this code in functions.php file.

add_action( 'admin_enqueue_scripts', function() { 
wp_enqueue_script('suggest-js', get_stylesheet_directory_uri().'/js/suggest.js', array( 'suggest' ), '1.0', true );

Create suggest.js in theme folder and put this code in suggest.js file

(function(window, document, $, undefined){

var hpadmin = {};

  hpadmin.init = function() {

    $('#blogs_creators').suggest( window.ajaxurl + "?action=ajax-tag-search&tax=category", {multiple:true, multipleSep: ","});



})(window, document, jQuery);

jQuery('#blogs_creators').suggest( window.ajaxurl + "?action=hwp_ajax_page_search", {multiple:true, multipleSep: ","})

Note: #blogs_creators is a settings custom field id.

Now put this code also in functions.php file.

add_action( 'wp_ajax_hwp_ajax_page_search', function() {

            $s = wp_unslash( $_GET['q'] );

            $comma = _x( ',', 'page delimiter' );
            if ( ',' !== $comma )
                $s = str_replace( $comma, ',', $s );
            if ( false !== strpos( $s, ',' ) ) {
                $s = explode( ',', $s );
                $s = $s[count( $s ) - 1];
            $s = trim( $s );

            $term_search_min_chars = 2;

            $the_query = new WP_Query( 
                    's' => $s,
                    'posts_per_page' => 5,
                    'post_type' => 'page'

            if ( $the_query->have_posts() ) {
                while ( $the_query->have_posts() ) {
                    $results[] = get_the_title();
                /* Restore original Post Data */
            } else {
                $results = 'No results';

            echo join( $results, "\n" );

How to call restful api from javascript or hit rest api URL from javascript.

What is REST api?
REST stands for Representational State Transfer. (It is sometimes spelled "ReST".) It relies on a stateless, client-server, cacheable communications protocol and in virtually all cases, the HTTP protocol is used. REST is an architecture style for designing networked applications. 
 Use following code to hit rest api url from javascript and it returns  in json format.
 var myJSONData = {"key1":"value1","key2":"value2","key3":"value3"};

            type: 'POST',
            url: '',//rest api url
            data: myJSONData,
            dataType: 'application/json',
            success: function(data) { 
             alert("request posted to the sever successfully");
          } // Success Function end
          });   // Ajax Call end

How to create load more posts in wordpress using jQuery Ajax

Step 1: Put the following javascript in the section.
<script type="text/javascript">
jQuery(document).ready(function($) {
  var page = 1; // What page we are on.
  var ppp = 3; // Post per page
                var posts = 3;
                var author_posts = parseInt(<?php echo get_the_author_posts(); ?> ); // Get all posts
              $("#load_more_posts").click(function() {
               if ((author_posts - posts ) < 0) {
                    $("#load_more_posts").css({'cursor': 'default','opacity': '0.61'});
                    $("#load_more_posts").text('No more posts!');
                }else {
                    OffSet = (page * ppp);
                    type: "GET",
                    url: "/WordPress/wp-admin/admin-ajax.php",
                    dataType: 'html',
                    data: ({ action: 'loadMore', offset:OffSet , ppp: ppp}),
                    success: function(data){    
                    //$('#load_posts').append( $.parseHTML(data));
                    var $items = $($.parseHTML(data));
                    $('#load_posts').append( $items ).isotope( 'appended', $items );
                    // #load_posts is the id of main posts container
                    posts = posts + 3;
                    if ((author_posts - posts ) < 0) {
                        $("#load_more_posts").css({'cursor': 'default','opacity': '0.61'});
                        $("#load_more_posts").text('No more posts!');
Step 2: After that put the following code in function.php file.
 function loadMore() {
        $offset     = $_GET["offset"];
        $ppp         = $_GET["ppp"];
        $args2         = array( 'posts_per_page' => $ppp, 'offset' => $offset, 'orderby' => 'DESC');
        $custom2     = new WP_Query($args2);
        // the Loop
        while ($custom2->have_posts()) : $custom2->the_post();  ?>
        <div class="item">
        <div class="grid-text">   
        <?php the_content('Read More...');?>
        // Reset Query
add_action('wp_ajax_loadMore', 'loadMore');
add_action('wp_ajax_nopriv_loadMore', 'loadMore'); // not really needed
Step 3: Finally put the following code line in index.php page after closing main div of posts container.
<div id="load_more_posts"> Load More</div>
