Pencarian AJAX pada halaman posting berdasarkan jenis posting kustom

Saya mengalami masalah membuat pencarian ajax di halaman posting tunggal saya. Saya perlu membatasi hasil pencarian untuk jenis posting khusus "fod_videos" dan "posting" dan kategori 12. Masalah saya adalah pencarian mengembalikan semua posting di bawah filter tersebut dan tidak mengambil nilai pencarian. Saya kira saya kehilangan sesuatu yang jelas tapi saya bisa mengetahuinya. Ini pengaturan saya.

<div class="panel">
  <h2>Search Videos</h2>
  <div id="my-search">
   <form role="search" method="get" id="searchform" action="http://myurl.com/" >
    <input type="text" value="" name="s" id="s" />
    <input type="submit" id="searchsubmit" value="Search" />
   </form>
  </div>
</div>

add_action('wp_ajax_wpa5000_search', 'wpa5000_search');
add_action('wp_ajax_nopriv_wpa5000_search', 'wpa5000_search');
function wpa5000_search(){
  global $wp_query;
  $search = $_POST['search_val'];
  $args = array(
    's' => $search,
    'posts_per_page' => 10,
    'cat' => 12, 
    'post_type' => array( 'post','fod_videos'  )
  );
  $wp_query = new WP_Query( $args );

  get_template_part( 'video-search-results' );

  exit;
}

add_action( 'wp_enqueue_scripts', 'wpa56343_scripts', 100 );
function wpa56343_scripts() {
 wp_enqueue_script(
    'wpa56343_script',
    get_template_directory_uri() . '/libs/search.js?ver=1.0',
    array( 'jquery' ),
    null,
    false
 );
 wp_localize_script(
    'wpa56343_script',
    'WPaAjax',
    array(
        'ajaxurl' => admin_url( 'admin-ajax.php' )
    )
 );
}

// search.php

$(document).ready(function($){
 $('#searchsubmit').click(function(e){
    var $panel = $(this).closest(".panel");
    $panel.empty();
    e.preventDefault();
    var search_val=$("#s").val();
    $.post(
        WPaAjax.ajaxurl,
        {
            action : 'wpa5000_search',
            search_val : search_val
        },
        function( response ) {
            $panel.append( response );
        }
    );
 });
});

//video-search-results.php

<?php
 while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
   //STUFF
<?php endwhile; ?>

Alih-alih 'cat' => 12dan $wp_querymenggunakan 'category_name' => slugdan get_posts().

Berikut ini adalah contoh dasar cara kerjanya:

PHP

add_action( 'wp_loaded', array ( 'T5_Ajax_Search', 'init' ) );

/**
 * Ajaxify the search form.
 */
class T5_Ajax_Search
{
    /**
     * The main instance. You can create further instances for unit tests.
     * @type object
     */
    protected static $instance = NULL;

    /**
     * Action name used by AJAX callback handlers
     * @type string
     */
    protected $action = 't5_ajax_search';

    /**
     * Handler for initial load.
     *
     * @wp-hook wp_loaded
     * @return void
     */
    public static function init()
    {
        NULL === self::$instance and self::$instance = new self;
        return self::$instance;
    }

    /**
     * Constructor. Registers the actions.
     *
     *  @wp-hook wp_loaded
     *  @return object
     */
    public function __construct()
    {
        $callback = array ( $this, 'search' );
        add_action( 'wp_ajax_'        . $this->action,        $callback );
        add_action( 'wp_ajax_nopriv_' . $this->action, $callback );
        add_action( 'wp_enqueue_scripts', array ( $this, 'register_script' ) );
    }

    /**
     * Callback for AJAX search.
     *
     * @wp-hook wp_ajax_t5_ajax_search
     * @wp-hook wp_ajax_nopriv_t5_ajax_search
     * @return void
     */
    public function search()
    {
        $args  = array ( 's' => $_POST['search_term'] );
        $args  = apply_filters( 't5_ajax_search_args', $args );
        $posts = get_posts( $args );
        if ( $posts )
        {
            $this->render_search_results( $posts );
        }
        else
        {
            print '<b>nothing found</b>';
        }
        exit;
    }

    /**
     * Create markup from $posts
     *
     * @param array $posts Array of post objects
     * @return void
     */
    protected function render_search_results( $posts )
    {
        print '<ul class="t5-ajax-search-results">';

        foreach ( $posts as $post )
        {
            printf(
                '<li><a href="%1$s">%2$s</a></li>',
                get_permalink( $post->ID ),
                esc_html( $post->post_title )
            );
        }
        print '</ul>';
    }

    /**
     * Register script and local variables.
     *
     * @wp-hook wp_enqueue_scripts
     * @return void
     */
    public function register_script()
    {
        wp_enqueue_script(
            't5-ajax',
            #plugins_url( __FILE__ ) . '/search.js',
            plugins_url( 'search.js', __FILE__ ),
            array ( 'jquery' ),
            NULL,
            TRUE
        );

        wp_localize_script(
            't5-ajax',
            'T5Ajax',
            array(
                'ajaxurl' => admin_url( 'admin-ajax.php' ),
                'action'  => $this->action
            )
        );
    }
}

JavaScript search.js

jQuery( function( $ ) {
    // search filed
    var $s = $( '#s' );
    // the search form
    var $sForm = $s.closest( 'form' );
    console.log( $sForm );
    $sForm.on( 'submit', function( event) {
        event.preventDefault();
        $.post(
            T5Ajax.ajaxurl,
            {
                action:     T5Ajax.action,
                search_term: $s.val()
            },
            function( response ) {
                // just append the result to the search form.
                $sForm.append( response );
            }
        );
    });
});

Membatasi pencarian

add_filter( 't5_ajax_search_args', 'restrict_t5_search' );

function restrict_t5_search( $args )
{
    $args['post_type'] = array ( 'post', 'fod_videos' );
    $args['category_name']       = 'category-slug';
    return $args;
}

Alih-alih saya, $this->render_search_results( $posts );Anda juga dapat memuat template dari tema Anda dan menggunakan $postsarray dalam hasil yang lebih canggih. :)

Saya mendapatkan kode asli berfungsi, tetapi dengan jenis posting khusus (tanpa kategori). Tambahkan input tersembunyi di formulir Anda dengan jenis posting Anda seperti ini:

<input type="hidden" name="post_type" value="fod_videos" />
