Hi Andy! Thanks for your hints.
As you said, multibyte characters were filtered out by the
Sanitize::paranoid method.
So I replaced it with my own sanitize method.
I don't know if it's a good way or not, but it works properly.
function in_one($match = null) {
//uses('Sanitize');
if (isset($this->data['Form']['search'])) {
if (!$this->data['Form']['search']) {
$this->_addFlash('You need to search for
something');
}
//return $this->redirect
(array(Sanitize::paranoid($this-
>data['Form']['search'])));
return $this->redirect
(array($this->mb_paranoid($this->data['Form']
['search'])));
}
if ($match) {
//$match = Sanitize::paranoid($match);
$match = $this->mb_paranoid($match);
$this->_addFlash('Showing results for Titles matching
"'.
$match.'"');
$criteria = array('Title.title'=>"LIKE %$match%");
list($order,$limit,$page) = $this->Pagination-
>init($criteria,null,array('ajaxAutoDetect'=>false));
$this->data =
$this->{$this->modelClass}->findAll($criteria, null,
$order, $limit, $page);
$this->data['Form']['search'] = $match;
} else {
$this->data = null;
}
$this->render('in_one');
}
function mb_paranoid($string, $allowed = array()) {
$allow = null;
if (!empty($allowed)) {
foreach($allowed as $value) {
$allow .= "\\$value";
}
}
if (is_array($string)) {
foreach($string as $key => $clean) {
$cleaned[$key] = $this->mb_preg_replace($clean,
$allow);
}
} else {
$cleaned = $this->mb_preg_replace($string, $allow);
}
return $cleaned;
}
function mb_preg_replace($string, $allow) {
// Allows UTF-8 characters
$cleaned = preg_replace(
"/[^{$allow}\\x00-\\x7F\\xC0-\\xDF\\x80-\\xBF\\xE0-\\xEF\\x80-\\xBF\
\x80-\\xBF]/", "", $string);
// Strips blank spaces from the beginning/end of a
string
$cleaned = preg_replace('/^[ ]*(.*?)[ ]*$/u', '$1',
$cleaned);
// Strips tags from a string
$cleaned = preg_replace('/[\<\>\(\)\{\}\[\]]/u', '$1',
$cleaned);
return $cleaned;
}
Thanks again for your work!
