Solved: symbol validation check question - wolfgang1983 - 04-05-2018
Hi,
I have this code below which lets me validate folder names.
PHP Code:
$is_correct_foldername = strpbrk($this->input->post('folder'), "\\/?%*:@#${}|\"<>");
How can I make sure folder name contains no spaces. As you can see in my strpbrk I have symbols that are not allow.
Thanks

Found solution did like
PHP Code:
$is_correct_foldername = strpbrk($this->input->post('folder'), "\\/?%*:@#$|\"<>" . "{}" . " ");

Personally I would match characters I want instead of those I don't want. Right now you can use chines letters in your folder name, are you allowed to do so?
PHP Code:
$re = '/\W/'; // \W matches any non-word character (equal to [^a-zA-Z0-9_])
$str = $this->input->post('folder');
$is_correct_foldername = !preg_match($re, $str) ? true : false;
This will give you false on every character except:
a-z
A-Z
0-9

And spaces?

It won't allow space.
