codeigniter 1.7 on PHP5.3

[eluser]m4rw3r[/eluser]
The reason is that preg_quote() quotes the dash ("-") character in PHP 5.3, which means that you should either remove the call to preg_quote(), or to replace it with something like this:

Code:

str_replace('\\-', '-', preg_quote($this->config->item('permitted_uri_chars'))

So the if should be like this:

Code:

if ( ! preg_match(”|^[”.$this->config->item(‘permitted_uri_chars’).”]+$|i”, $str))
// or
if ( ! preg_match(”|^[”.str_replace('\\-', '-', preg_quote($this->config->item(‘permitted_uri_chars’))).”]+$|i”, $str))
