我收到了一个相关的Catchable致命错误:类WP_User的对象无法在第766行的/wp-includes/formatting.php中转换为字符串。我找到了一个与https://wordpress.org/support/topic/catchable-fatal-error-object-of-class-wp_error-could-not-be-converted-to-string-11
我正在使用的php,我认为应该正在使用的是:
add_filter('gform_field_value_pm_first', 'populate_pm_first');
function populate_pm_first($value){
return $user_info = get_userdata(get_current_user_id());
$first_name = $user_info->first_name;
echo "$first_name";
}
我得到的错误与formatting.php有关:
/ **
* Checks for invalid UTF8 in a string.
*
* @since 2.8.0
*
* @param string $string The text which is to be checked.
* @param boolean $strip Optional. Whether to attempt to strip out invalid UTF8. Default is false.
* @return string The checked text.
*/
function wp_check_invalid_utf8( $string, $strip = false ) {
$string = (string) $string;
if ( 0 === strlen( $string ) ) {
return '';
}
答案 0 :(得分:0)
我认为语法是:
$first_name = $user_info->user_firstname;
可能值得一试。希望这会有所帮助:)

您需要将用户名返回为字符串而不是整个用户object
。
add_filter('gform_field_value_pm_first', 'populate_pm_first');
function populate_pm_first($value)
{
$user_info = get_userdata(get_current_user_id());
$first_name = $user_info->first_name;
return $first_name; // return user name string
//echo "$first_name";
}
