I am currenly trying to get my form validation correct and somehow CI is throwing away some of the ‘\’ if i use it in the input fields. Below is the debugging code i used to pinpoint the problem.
$this->validation->set_error_delimiters('<div class="error">', '</div>');
if( count($_POST)){
echo("Voor: ");
echo($this->validation->name . " ");
}
if ($this->validation->run() == FALSE){ //validation failed, reload the view
$data['query_groups'] = $this->db->get('user_groups');
if(false || count($_POST)){
echo("NA: ");
echo($this->validation->name);
exit;
}
this gives the following output:
Voor: aaa\bbb NA: aaabbb
I checked everything until the validation->run and right at that point the ‘\’ disappears.
Im not sure if this is already known since i know there are already some bugreports involving escaping.
(PS i know there shouldn’t be any backslashes in a name anyway 
)
I think i found it:
line 663 in validation.php
return str_replace(array("'", '"', '<', '>'), array("'", """, '<', '>'), stripslashes($str));
There shouldn’t be a stripslashes there right?
EDIT
I also posted this in the bug topic just to be sure it is known .
