Wordpress 中 add_post_meta() 函数的问题

问题描述

当像这样使用它时：

add_post_Meta($post_ID,'Name',"Bob",true );   

工作正常，但是当将字符串值存储在变量中时，例如：

$name = "Bob";
add_post_Meta($post_ID,$name,true ); // <---- This doesn't work.

请帮忙。谢谢。

解决方法

试试下面的代码。

$name = "Bob"; 
update_post_meta($post_ID,'Name',$name );

,

$latestVideo = wp_get_recent_posts(array(
    'numberposts' => 1,'post_type'   =>'video','post_status' => 'publish'
));

$latestVideoWeek = get_post_meta( $latestVideo[0]["ID"],"Week",true);
$latestVideoDate = get_post_meta( $latestVideo[0]["ID"],"Date",true);

function meta_info_video( $post_ID ) {
    add_post_meta( $post_ID,'Semana',$latestVideoWeek,true );
    add_post_meta( $post_ID,'Fecha',$latestVideoDate,'URL','0',true  );
}

add_action( 'draft_video','meta_info_video' );
