发生的事情是，全局变量$post 没有出现在帖子页面上-因此在下面的条件中，表单正在处理，
if ( \'POST\' == $_SERVER[\'REQUEST_METHOD\'] && ! empty($_POST[\'post_id\']) && ! empty($_POST[\'post_title\']) && isset($_POST[\'postcontent\']) ) {
header(\'Location: /\');
$post_id = $post->ID;
$post = array(
\'ID\' => esc_sql($post_id),
\'post_content\' => esc_sql($_POST[\'postcontent\']),
\'post_title\' => esc_sql($_POST[\'post_title\'])
);
wp_update_post($post);
if ( isset($_POST[\'owner_name\']) ) update_post_meta($post_id, \'owner_name\', esc_sql($_POST[\'owner_name\']) );
if ( isset($_POST[\'phone\']) ) update_post_meta($post_id, \'phone\', true );
if ( isset($_POST[\'address\']) ) update_post_meta($post_id, \'address\', true );
if ( isset($_POST[\'zip_code\']) ) update_post_meta($post_id, \'zip_code\', true );
if ( isset($_POST[\'add_coupon\']) ) update_post_meta($post_id, \'add_coupon\', true );
}
$post_id 计算结果为null。
我的解决方案是从$_POST 对象以下是修订后的代码：
if ( \'POST\' == $_SERVER[\'REQUEST_METHOD\'] && ! empty($_POST[\'post_id\']) && ! empty($_POST[\'post_title\']) && isset($_POST[\'postcontent\']) ) {
header(\'Location: /\');
$post_id = $post->ID;
$post = array(
\'ID\' => $_POST[\'post_id\'], // use $_POST object instead of global $post
\'post_content\' => esc_sql($_POST[\'postcontent\']),
\'post_title\' => esc_sql($_POST[\'post_title\'])
);
wp_update_post($post);
if ( isset($_POST[\'owner_name\']) ) update_post_meta($_POST[\'post_id\'], \'owner_name\', esc_sql($_POST[\'owner_name\']) );
if ( isset($_POST[\'phone\']) ) update_post_meta($_POST[\'post_id\'], \'phone\', esc_sql($_POST[\'phone\']) );
if ( isset($_POST[\'address\']) ) update_post_meta($_POST[\'post_id\'], \'address\', esc_sql($_POST[\'address\']) );
if ( isset($_POST[\'zip_code\']) ) update_post_meta($_POST[\'post_id\'], \'zip_code\', esc_sql($_POST[\'zip_code\']) );
if ( isset($_POST[\'add_coupon\']) ) update_post_meta($_POST[\'post_id\'], \'add_coupon\', esc_sql($_POST[\'add_coupon\']) );
}
