我是PHP的新手，我有问题选择在例如TRANSGENDER FtM之间有空格的值，如果我使用TRANSGENDER-MtF然后能够保存它。与名称输入相同，这是代码：
<?php
include_once 'core/init.php';
$general->logged_out_protect();

关于截图，问题是您对“名字”的验证工作正常！我首先建议，为了进行此更改，您应该将表单更改为“First name（s）：”，以明确在此字段中允许任意数量的名字。理想情况下，您也应该使用字段名称。
您的代码是：
if (isset($_POST['first_name']) && !empty ($_POST['first_name'])){
if (ctype_alpha($_POST['first_name']) === false) {
$errors[] = 'Please enter your First Name with only letters!';
}
}
您的代码使用的函数是ctype_alpha，它不允许使用空格。您可以将其更改为：
if (isset($_POST['first_name']) && !empty ($_POST['first_name'])){
// Remove spaces from intermediate variable, to permit them
$firstNames = str_replace(' ', '', $_POST['first_name']);
if (ctype_alpha($firstNames) === false) {
$errors[] = 'Please enter your first name(s) with only letters!';
}
}
