Get_posts（）がカスタム投稿タイプから選択したカテゴリ投稿のみを返さないのはなぜですか？

私はajax経由でランダムな投稿とURLを取得するウィジェットプラグインを使用しています。関数を書き換えるのを助けてくれてありがとう fischi 。問題は、関数がCPTからすべての投稿を返すため、カテゴリ選択が機能しないことです。

php

function get_random_post_tu() {

    // Simple as that, get a random post
    // I put it in an array to make it easier to read
    $args = array(
        'post_type'   => 'portfolio-item','orderby'     => 'Rand',
        'numberposts' => 1
    );

    // Add the Category parameter, if set
    if ( isset( $_POST['usecategory'] ) && intval( $_POST['usecategory'] ) != 0 ) {
        $args['taxonomy=portfolio-category'] = $_POST['usecategory'];
    }
    $posts = get_posts( $args );

    /**
     * This actually gives us an array of post objects, so we should double check 
     * if there is indeed a post in there.
     */
    $data = array();
    if (is_array($posts) && isset($posts[0])) {

        // add this to use on frontend
        $data['status']  = 'success';
        $data['link']    = get_permalink($posts[0]->ID);
        $data['title']   = get_the_title($posts[0]->ID);
        $data['thumb']   = get_the_post_thumbnail($posts[0]->ID);
        $data['content'] = get_post_field('post_content', $posts[0]->ID);

    } else {

        // add a error status
        $data['status'] = 'error';

    }    

    // use the WordPress built in function
    wp_send_json( $data ); // this is required to return a proper result

}

JQuery

jQuery(document).ready(function($) {
$('.grp_getnew').on('click', function(){
    var data = {
        action: 'get_random_post_tu',
        usecategory: $('#categoryselect').val()
    };

    $.post( ajax_object.ajax_url, data, function(response) {
        if ( response.status != 'error' ) {
            var $link = $("<a href='" + response.link + "'>" + response.title + "</a><span >" + response.content +"</span>");
            $('.grp_content').html($link);
        }
    }, "json");
});

Get_posts（）がカスタム投稿タイプから選択したカテゴリ投稿のみを返さないのはなぜですか？どうぞ、どうぞ！

UPDATEそれで私は私のajax呼び出しのprint_r($args);を作った、そしてそれは示す

Array ( [post_type] => portfolio-item [orderby] => Rand [posts_per_page] => 1 [tax_query] => Array ( [taxonomy] => portfolio-category [field] => term_id [terms] => 40 ) ) {"status":"success","link":"http:\/\/marinaa9.bget.ru\/portfolio-item\/rough-ske‌​tches-2\/","title":"Rough Sketches","thumb":"\"ss\"","content":"[\/vc_column_text][\/vc_column][\/vc_row]"‌​}

まず、あなたのカスタム投稿タイプはportfolio-itemではなくportfolio_itemです。投稿タイプを$this->base名で登録し、以前は$this->base = 'portfolio-item';を作成したことに注意してください。また、numberpostsは時代遅れです。代わりにpost_per_pageを使用してください。

$args = array(
    // 'post_type'  => 'portfolio_item',
    'post_type'     => 'portfolio-item',
    'orderby'       => 'Rand',
    'post_per_page' => 1
);

それなら、あなたの問い合わせの分類論は間違っています。次のようにtax_query引数を使用する必要があります。

if ( isset( $_POST['usecategory'] ) && intval( $_POST['usecategory'] ) != 0 ) {
  $args['tax_query'] = array(
    array(
      'taxonomy' => 'portfolio-category',
      'terms'    => intval( $_POST['usecategory'] )
    )
  );

}

$posts = get_posts( $args );

デフォルトでは、引数はIDという用語を実行します。 $_POST['usecategory']が用語IDではなく用語slugの場合：

if ( isset( $_POST['usecategory'] ) && intval( $_POST['usecategory'] ) != 0 ) {
  $args['tax_query'] = array(
    array(
      'taxonomy' => 'portfolio-category',
      'field'    => 'slug',
      'terms'    => $_POST['usecategory']
    )
  );

}

Codex：WP_Query：taxomomyパラメータ ですべての可能な組み合わせを指定できます。

また、あなたのjQueryは構文エラーがあります、あなたは});を逃しました：

jQuery(document).ready(function($) {
  $('.grp_getnew').on('click', function(e){
    e.preventDefault();
    var data = {
        action: 'get_random_post_tu',
        usecategory: $('#categoryselect').val()
    };

    $.post( ajax_object.ajax_url, data, function(response) {
        if ( response.status != 'error' ) {
            var $link = $("<a href='" + response.link + "'>" + response.title + "</a><span >" + response.content +"</span>");
            $('.grp_content').html($link);
        }
    }, "json");
  });
});
