[英]WordPress: wp_mail function only works once in foreach loop
我正在运行一个具有删除旧事件(基于自定义字段)功能的cron。 该函数可以查找并删除过去的所有事件。 到现在为止还挺好...
现在,我想向事件的作者发送电子邮件,表明该事件已被删除。 我通过在foreach中使用额外的wp_mail
函数来执行此操作。
现在的问题是,只有最后的旧事件被删除。 也许这与foreach内邮件( $post
, $author
,...)的变量有关?
我在这里阅读了有关该问题的内容,但我不明白: 循环中的wp_mail(),仅发送到最后一个地址
这是我的代码:
function get_delete_old_events() {
$past_query = date('Y-m-d', strtotime('-1 day'));
// Set our query arguments
$args = [
'fields' => 'ids', // Only get post ID's to improve performance
'post_type' => 'event', // Post type
'posts_per_page' => -1,
'meta_query' => [
[
'key' => 'gid_22', // Replace this with the event end date meta key.
'value' => $past_query,
'compare' => '<='
]
]
];
$q = get_posts( $args );
// Check if we have posts to delete, if not, return false
if ( !$q )
return false;
// OK, we have posts to delete, lets delete them
foreach ( $q as $id )
/* start e-mail */
$headers[] = 'From: SITENAME <hello@domain.com>';
$post = get_post($id);
$author = get_userdata($post->post_author);
$subject = "SUBJECT: ".$post->post_title."";
$message = "THE MESSAGE BODY";
wp_mail($author->user_email, $subject, $message, $headers);
/* end e-mail */
wp_trash_post( $id );
}
// expired_post_delete hook fires when the Cron is executed
add_action( 'old_event_delete', 'get_delete_old_events' );
// Add function to register event to wp
add_action( 'wp', 'register_daily_events_delete_event');
function register_daily_events_delete_event() {
// Make sure this event hasn't been scheduled
if( !wp_next_scheduled( 'old_event_delete' ) ) {
// Schedule the event
wp_schedule_event( time(), 'hourly', 'old_event_delete' );
}
}
wp_mail
函数返回bool(请参阅WordPress文档 )。 因此,它退出函数,因为它在第一次迭代中返回值。
只需在wp_mail之前添加一个变量
$is_sent = wp_mail($author->user_email, $subject, $message, $headers);
那应该可以了。
尝试下面的代码。
function get_delete_old_events() {
$past_query = date('Y-m-d', strtotime('-1 day'));
// WP_Query arguments
$args = array(
'fields' => 'ids', // Only get post ID's to improve performance
'post_type' => array( 'event' ), //post type
'posts_per_page' => '-1',//fetch all posts,
'meta_query' =>array(
'relation' => 'AND',
array(
'key' => 'gid_22',
'value' => $past_query,
'compare' => '<='
)
)
);
// The Query
$query = new WP_Query( $args );
// The Loop
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
// do something
$headers[] = 'From: SITENAME <hello@domain.com>';
$postid = get_the_ID();
$post = get_post($postid);
$author = get_userdata($post->post_author);
$subject = "SUBJECT: ".get_the_title()."";
$message = "THE MESSAGE BODY";
wp_mail($author->user_email, $subject, $message, $headers);
wp_trash_post( $id );
}
} else {
// no posts found
return false;
}
// Restore original Post Data
wp_reset_postdata();
}
