Laravel - Validate only letters, numbers and spaces using regex
提问by gnardell
I am trying to validate a field made ??up of letters, numbers and spaces in this way:
我正在尝试以这种方式验证由字母、数字和空格组成的字段:
$rules = array(
'field'=> 'regex:/([A-Za-z0-9 ])+/'
);
but if I try to insert characters like ' " and others, the validation still has to be successful.
但是如果我尝试插入像 '" 和其他字符这样的字符,验证仍然必须成功。
What's wrong 'in my regular expression?
我的正则表达式有什么问题?
回答by Cas Bloem
$rules = array(
'field'=> 'regex:/(^[A-Za-z0-9 ]+$)+/'
);

If you are working with utf-8
如果您使用的是 utf-8
$rules = array(
'field'=> 'regex:/(^[\pL0-9 ]+$/u'
);
