wordpress – 如何在没有标题的情况下编写wp_mail

没有标题写wp_mail可以吗？

该功能的用途是
<？PHP wp_mail($to,$subject,$message,$headers,$attachments); ？&GT 问：我可以像这样使用它吗？ <？PHP wp_mail($to,$subject,$message); ？&GT

解决方法:

是的,如果你查看下面的文字,参数$headers表示它(字符串或数组)(可选)

$to
(string or array) (required) The intended recipient(s). Multiple recipients may be specified using an array or a comma-separated string.
Default: None

$subject
(string) (required) The subject of the message.
Default: None

$message
(string) (required) Message content.
Default: None

$headers
(string or array) (optional) Mail headers to send with the message. (advanced)
Default: Empty

$attachments
(string or array) (optional) Files to attach: a single filename, an array of filenames, or a newline-delimited string list of multiple filenames. (advanced)
Default: Empty
