我有一个名为individual_team_member的自定义页面模板，我想要自定义元数据。元数据显示正确，我的字段显示。问题是当我填写任何字段并点击＆＃34;更新＆＃34;在我的帖子上它没有显示元字段中的值。我相信这是由$metaKey造成的，但我不确定为什么价值没有被保存。我已经在下面提供了所有的metaBox代码，提前谢谢！
<?php
/* Create one or more meta boxes to be displayed on the post editor screen. */
function test_wealth_add_meta_boxes( $post ) {
// 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
'side', // context (advanced, normal, or side)
'high' // priority (high, core, default or low)
);
}
}
// Make sure to use "_" instead of "-"
add_action( 'add_meta_boxes_page', 'test_wealth_add_meta_boxes' );

答案 0 :(得分：1)
替换它：
https://geo.yahoo.com/b?s=792600534
..用这个：
/* 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'] );
或你实际上可以缩短它：
/* 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'] : '';
..进入这个：
/* 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'] );
/* Get the meta key. */
$meta_key1 = 'title_meta_field';
$meta_key2 = 'test_page_template_metabox2';
$meta_key3 = 'test_page_template_metabox3';
/* Get the meta value of the custom field key. */
$meta_value = get_post_meta( $post_id, $meta_key1, true );
$meta_value = get_post_meta( $post_id, $meta_key2, true );
$meta_value = get_post_meta( $post_id, $meta_key3, true );
/* If a new meta value was added and there was no previous value, add it. */
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 )
update_post_meta( $post_id, $meta_key1, $title_meta_value );
/* If there is no new meta value but an old value exists, delete it. */
elseif ( '' == $title_meta_value && $meta_value )
delete_post_meta( $post_id, $meta_key1, $meta_value );
/* If a new meta value was added and there was no previous value, add it. */
// if ( $phone_meta_value && '' == $meta_value )
// add_post_meta( $post_id, $meta_key2, $phone_meta_value, true );
// /* If the new meta value does not match the old value, update it. */
// elseif ( $phone_meta_value && $new_meta_value != $meta_value )
// update_post_meta( $post_id, $meta_key2, $phone_meta_value );
