我做了一些尝试，但在电子邮件中，我把变量$downloads出现Array。其余部分显示在右边，标题和页面链接。但可下载产品的url没有。
functions.php中的代码:
add_action('draft_to_publish', 'my_product_add');
function my_product_add($post)
{
if ($post->post_type == "product") {
$productId = $post->ID;
$post_title = get_the_title($post_id);
$tld_prod_url = esc_url(get_permalink($post_id));
$subject = "Product Added Notification";
$product = new WC_Product($post_id);
$downloads.= $product->get_files();
$to = "me@test.com";
$body.= "The following product was added: 'n'n" . $post_title . "'n" . $tld_prod_url . "'n" . $downloads . "'n'nThanks,'n";
wp_mail($to, $subject, $body);
}
}
很可能$downloads.= $product->get_files()试图将array分配给字符串变量。你必须转换数组:
对于普通的电子邮件消息，将是:
$downloads.= implode("'r'n", $product->get_files());
如果你坚持恼人的html电子邮件信息，那就是:
$downloads.= implode("<br>'r'n", $product->get_files());
$downloads是一个数组，因此你不能直接输出它。必须使用foreach循环遍历数组并创建一个字符串。例如:
$downloadsString = '';
foreach($downloads as $download){
$downloadsString = "<a href='".$download['file']."'>".$download['name']."</a>'r'n";
}
$body.= "The following product was added: 'n'n" . $post_title . "'n" . $tld_prod_url . "'n" . $downloadsString . "'n'nThanks,'n";
我不知道数组的索引，所以这只是一个例子，但这是这样做的
