我有一个HTML表单，用于直接从我的页面发送电子邮件到我的电子邮件。发送电子邮件和表单的代码发布在下面。
我希望我的表格也能接受cha，Ž，Ž，ž，Š，š，Ć，... ...... 我知道代码中写入允许的字符串的位置，但由于我对PHP的经验很少，所以我不知道如何在现有的字符串中添加其他字符。
另外，在我看来，代码只检查字段“name”，“email”nad“url”，而不是“comments”和“subject”。我是coorect吗？

答案 0 :(得分：0)
首先确保您使用utf-8作为网页的编码。
正则表达式（PCRE）用于验证输入。这个名字是：
!preg_match("/^[a-zA-Z-'\s]*$/", ...)
此表达式不是utf-8模式。它只匹配字节。在utf-8中，像Č这样的字符是多个字节。修饰符u激活utf-8模式。另外，-应该是字符类中的第一个或最后一个元素。在两个其他字符之间，它定义了一个范围（如a-z）。
!preg_match("/^[a-zA-Z'\\s-]*$/u", ...)
在此模式下，您可以将特殊字符添加到字符类中。您必须确保您的编辑器/ ide将PHP存储为utf-8。
!preg_match("/^[a-zA-Z'\\sČ-]*$/u", ...)
在类中添加多个字符会非常快速地增加模式的大小，并且忘记字符很容易。 unicode properties是一个更好的解决方案。 “\ pL”是所有字母的缩写（包括西里尔字母，韩文字母......）。这是我建议的验证。
!preg_match("/^[\\pL'\\s-]*$/u", ...)
但您可以将此限制为更具体的群体，例如“拉丁语”。
!preg_match("/^[\\p{Latin}'\\s-]*$/u", ...)
示例：
// latin letters, valid: int(1)
var_dump(
preg_match('(^\p{Latin}+$)u', 'aäČ')
);
// latin letters, invalid: int(0)
var_dump(
preg_match('(^\p{Latin}+$)u', 'Русский')
);
// all letters, valid: int(1)
var_dump(
preg_match('(^\pL+$)u', 'Русский')
);
