Php 多字段Wordpress元数据库未保存

我有一个名为“个人团队成员”的自定义页面模板，我需要自定义元数据。“元盒”显示“正确”，并显示“我的字段”。问题是，当我填写任何字段并在帖子上单击“更新”时，它不会在元字段中显示值。我相信这是由我的$metaKey引起的，但我不确定为什么没有保存该值。我已经在下面包含了我所有的metaBox代码，提前谢谢

<?php
/* Create one or more meta boxes to be displayed on the post editor screen. */

    // Get the page template post meta
    $page_template = get_post_meta( $post->ID, '_wp_page_template', true );
    // If the current page uses our specific
    // template, then output our custom metabox
    if ( 'individual_team_member.php' == $page_template ) {
        add_meta_box(
            'member-title', // Metabox HTML ID attribute
            'Team Member Details', // Metabox title
            'test_page_template_metabox', // callback name
            'page', // post type

替换此项：

    /* Get the posted data. */
    $title_meta_value = isset( $_POST['member-title'] );
    $phone_meta_value = isset( $_POST['member-phone'] );
    $email_meta_value = isset( $_POST['member-email'] );

。。为此：

    /* Get the posted data. */
    $title_meta_value = isset( $_POST['member-title'] ) ? $_POST['member-title'] : '';
    $phone_meta_value = isset( $_POST['member-phone'] ) ? $_POST['member-phone'] : '';
    $email_meta_value = isset( $_POST['member-email'] ) ? $_POST['member-email'] : '';

    if ( $title_meta_value && '' == $meta_value )
        add_post_meta( $post_id, $meta_key1, $title_meta_value, true );

    /* If the new meta value does not match the old value, update it. */
    elseif ( $title_meta_value && $title_meta_value != $meta_value )
