i'm using sanitize::paranoid on a string but i need to exclude a few special characters but it doesn't seem to work.
$content=sanitize::paranoid($content,array('à',' '));
I've changed the encoding of my file from ansi to utf8 but cakephp doesn't really like it so i need to find another way.
That array should contain the list of characters to exclude from sanitization, but it keep removing the "à" and i want those character in the final string.
Sanitize:paranoid is a simple preg_replace ($allow is just additional characters, escaped):
preg_replace("/[^{$allow}a-zA-Z0-9]/", '', $string);
As you can see, paranoid is quite paranoid... doesn't accept non-ascii letters by default.
The file where you had the à was probably saved in another encoding (working on windows?)
Anyway, if you want you can write a better filter by using /[^\p{L}]/u, which excludes letters in any lanaguage.
Taken from the Sanitize::paranoid function:
cleaned = preg_replace("/[^{$allow}a-zA-Z0-9]/", '', $string);
Because your character (à) is not in this range it will not be returned. If you're using Cake 2.x you can override the Sanitize class in your app folder and replace all occurrences of:
a-zA-Z0-9
with:
\w
This should return the accented character (it does for me). You can also look at the multibyte functions if you like but that might be a problem if you're building a CMS.
it must be some special encoding problems that cakephp paranoid doesnt know
Sanitize::paranoid($badString, array(' ', '@')); @ is the allowed char
it should be working. i tried this example myself
