在woocommerce中自動將進口產品的產品類別設置為New in

Question

我將嘗試解釋我的目標是什么以及我已經做了什么。

我正在將一堆產品導入 WooCommerce，但現在我想添加一個功能，如果產品不超過 60 天，它會自動將產品類別設置為“新產品”。 在 60 天之后，它應該再次移出該類別。

可以說，我正在使用WordPress和WooCommerce學習php，所以如果我不知道某些事情，我很抱歉。

   function add_product_to_new_in()
{
    global $product;

    // Get the date for the product published and current date
    $start = date('n/h/Y', strtotime($product->get_date_created()));
    $today = date('n/j/Y');


    // Get the date for the start of the event and today's date
    $start = new \DateTime($start);
    $end = new \DateTime($today);

    //FInd the difference
    $difference = $start->diff($end);
    $days = $difference->d;

    // If the difference is less than 60, apply "NEW IN cat"
    if ($days = (60 < $days)) {
        wp_set_object_terms($product, 40, 'product_cat');
    }
}

如果您能以任何方式幫助我，我將不勝感激！

您可以在每次頁面加載時觸發的init鈎子上執行此操作。

首先，您必須獲得所有產品。

$args = array(
    'post_type'   => 'product',
    'posts_per_page' => -1
);

$products = new WP_Query( $args );
 
if ( $products->have_posts() ) {  while ( $products->have_posts() ) {  $products->the_post();
    // your logic will go here.
} wp_reset_postdata(); }

現在計算天數。

$product  = wc_get_product( get_the_ID() );
$datetime = $product->get_date_created();
$timezone = $datetime->getTimezone();
$now_time = new WC_DateTime();

$now_time->setTimezone($timezone);

$timestamp_diff = $now_time->getTimestamp() - $datetime->getTimestamp();
$data           = timestamp_to_array( $timestamp_diff );
$days           = $data['d'];

然后你可以使用wp_set_object_terms和wp_remove_object_terms來設置和刪除類別。

// If the difference is less than 60, apply "NEW IN cat"
if ( $days < 60 ) {
    wp_set_object_terms( get_the_ID(), 40, 'product_cat' );
}else{
    wp_remove_object_terms( get_the_ID(), 40, 'product_cat' );
}

完整的代碼。 在您的活動主題functions.php 文件中添加以下代碼。

function add_category_to_product_for_certain_days(){

    $args = array(
        'post_type'   => 'product',
        'posts_per_page' => -1
    );

    $products = new WP_Query( $args );
     
    if ( $products->have_posts() ) {  while ( $products->have_posts() ) {  $products->the_post();

        $product  = wc_get_product( get_the_ID() );
        $datetime = $product->get_date_created();
        $timezone = $datetime->getTimezone();
        $now_time = new WC_DateTime();

        $now_time->setTimezone($timezone);

        $timestamp_diff = $now_time->getTimestamp() - $datetime->getTimestamp();
        $data           = timestamp_to_array( $timestamp_diff );
        $days           = $data['d'];
        
        // If the difference is less than 60, apply "NEW IN cat"
        if ( $days < 60 ) {
            wp_set_object_terms( get_the_ID(), 40, 'product_cat' );
        }else{
            wp_remove_object_terms( get_the_ID(), 40, 'product_cat' );
        }

    } wp_reset_postdata(); }

}

add_action( 'init', 'add_category_to_product_for_certain_days', 10, 1 );

function timestamp_to_array( $timestamp ) {
    $d = floor($timestamp/86400);
    $_d = ($d < 10 ? '0' : '').$d;

    $h = floor(($timestamp-$d*86400)/3600);
    $_h = ($h < 10 ? '0' : '').$h;

    $m = floor(($timestamp-($d*86400+$h*3600))/60);
    $_m = ($m < 10 ? '0' : '').$m;

    $s = $timestamp-($d*86400+$h*3600+$m*60);
    $_s = ($s < 10 ? '0' : '').$s;

    return array('d' => $_d, 'h' => $_h, 'm' => $_m, 's' => $_s);
}

測試和工作。
