得到一个类别的所有产品

Question

我使用这个函数来获取ajax请求中一个类别的所有产品

function get_products()
 {
   $cat_id = $_POST['category'];
   $args = array(
  'post_type'             => 'product',
  'post_status'           => 'publish',
  'ignore_sticky_posts'   => 1,
  'posts_per_page'        => '12',
  'tax_query'             => array(
    array(
        'taxonomy'      => 'product_cat',
        'field' => 'term_id', //This is optional, as it defaults to 'term_id'
        'terms'         => $cat_id,
        'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
    ),
    array(
        'taxonomy'      => 'product_visibility',
        'field'         => 'slug',
        'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
        'operator'      => 'NOT IN'
    )
 )
);
 $products = new WP_Query($args);
 echo json_encode($products);

 wp_die();
}

然后我收到了每个产品的数据，但不是每个产品的全部数据。

我找不到形象或产品的价格，也找不到销售价格或价格

我想在脚本中得到这些数据

function get_div(obj)
{
console.log("heeeeeeeeeeeeeeeere");
console.log(obj.ID);
console.log(obj.post_name);
console.log(obj.regular_price);=> return undefined
}          

问题是什么？

例如，WP_Query只用于获取标准post数据。插件(如WC )的附加数据将不会被获取。

执行自定义查询

如果您想使用自定义查询，可以使用WC_产品_查询

将以下内容放在主题的functions.php中，并将javascript保存到一个单独的php文件中。快速测试使用WC默认示例产品。

// in theme's functions.php
// before init, no products is prepared if just direct call in functions.php, so to have quick test, need to place inside a init
add_action( 'init', 'ws365398_simple_test' );
function ws365398_simple_test() {
    add_action('wp_enqueue_scripts', 'ws365398_enqueue_scripts', 101);

    add_action( 'wp_ajax_my_action', 'get_products' );
    add_action( 'wp_ajax_nopriv_my_action', 'get_products' );
}

// actions for ajax
function get_products()
{
    if( !empty( $_POST['category'] ) ) {
        $cat_id = $_POST['category'];
    } else {
        $cat_id = 19; // default change to yours, in the test case ensure it have something by default
    }

    $args = array(
        'status'           => 'publish',
        'ignore_sticky_posts'   => 1,
        'posts_per_page'        => '12',
        'tax_query'             => array(
            'relation'          => 'AND', // relation of 2 taxonomy queries
            array(
                'taxonomy'      => 'product_cat',
                'field'         => 'term_id', //This is optional, as it defaults to 'term_id'
                'terms'         => $cat_id,
                'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
            ),
            array(
                'taxonomy'      => 'product_visibility',
                'field'         => 'slug',
                'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
                'operator'      => 'NOT IN'
            )
        )
    );
    $query = new WC_Product_Query($args);
    $products = $query->get_products();

    // convert to array data before pushing to json
    $product_arr = [];
    foreach ($products as $key => $product) {
        $product_arr[] = $product->get_data();
    }

    // echo json_encode($product_arr);
    wp_send_json_success( $product_arr ); // with success flag and use directly

    wp_die();
}

// enqueue ajax script
function ws365398_enqueue_scripts()
{
    wp_enqueue_script('test-custom-scripts', get_theme_file_uri('ws365398-test-ajax.php'), array(), 't' . time(), true);
}

function test_ajax() {
    let myData = {
      action: 'my_action',
    };

    jQuery.post('', myData, function (response) {

      if (response.success == true) {
        console.log(response);
        }
    });
}

要进行测试，只需为您的环境准备上面的带有修正路径的文件。在浏览器检查器中运行test_ajax()，您将看到如下内容：
