我在自定义分类法上设置了4个自定义元字段，出于某种原因，我的2个文本字段的字段值仅在第一次添加到数据库时更新。将其包括在；添加（&Q）；或者如果我创建了一个没有它们的分类法，然后将它们包含在；“编辑”；第一次形成。但只要我尝试更改这些值，数据库就不会得到更新。我做错了什么？
这是我的代码：
// Add the fields to the "groups" taxonomy, using our callback function
add_action( \'groups_add_form_fields\', \'groups_taxonomy_custom_fields\', 10, 2 ); // "Add new" form
add_action( \'groups_edit_form_fields\', \'groups_taxonomy_custom_fields\', 10, 2 ); // "Edit" form
function groups_taxonomy_custom_fields($term) {
// Get the page
global $pagenow;
// Set empty vars
$organization = \'\';
$email_domain = \'\';
$facilitators = array();
$access_ids = array();
// If we are on the "add new" page
if ($pagenow == \'edit-tags.php\') {
// Table setup
$cont1 = \'<div class="form-field">\';
$cont2 = \'\';
$cont3 = \'</div>\';
// If we are on the "edit" term page
} elseif ($pagenow == \'term.php\') {
// Check for existing taxonomy meta for the term you\'re editing
$term_id = isset($term->term_id) ? $term->term_id : null;
$organization = get_term_meta( $term_id, \'organization\', true );
$email_domain = get_term_meta( $term_id, \'email_domain\', true );
if (get_term_meta( $term_id, \'facilitators\', true )) {
$facilitators = get_term_meta( $term_id, \'facilitators\', true );
}
if (get_term_meta( $term_id, \'access_ids\', true )) {
$access_ids = get_term_meta( $term_id, \'access_ids\', true );
}
// Table setup
$cont1 = \'<tr class="form-field">
<th scope="row" valign="top">\';
$cont2 = \'</th>
<td>\';
$cont3 = \'</td>
</tr>\';
// Else nothing
} else {
$cont1 = \'\';
$cont2 = \'\';
$cont3 = \'\';
}
// Let\'s get all the webinar codes
$codes = get_terms( array(
\'taxonomy\' => eri_access_id_taxonomy(),
\'hide_empty\' => false,
\'order\' => \'DESC\',
) );
// Now get all the Facilitators
$users = get_users( array(
\'role__in\' => array( \'facilitator\' ),
\'orderby\' => \'display_name\',
\'order\' => \'ASC\'
) );

有趣的是，我的复选框字段每次都在更新，所以文本字段出现了一些问题。
