spaces in URLs converted to _

[eluser]sophistry[/eluser]
here is the standard set of permitted uri chars:

Code:

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';

note that the only thing that this config item is used for is in the URI.php lib where it either accepts or rejects the URI and passes it on.

Code:

/**
     * Filter segments for malicious characters
     *
     * @access    private
     * @param    string
     * @return    string
     */    
    function _filter_uri($str)
    {
        if ($str != '' AND $this->config->item('permitted_uri_chars') != '')
        {
            if ( ! preg_match("|^[".preg_quote($this->config->item('permitted_uri_chars'))."]+$|i", $str))
            {
                exit('The URI you submitted has disallowed characters.');
            }
        }
            
        return $str;
    }

so, the problem isn't with the permitted chars because otherwise you would be getting a "this URI has disallowed chars" message.

the problem is elsewhere.

i found this little quizzical note in the Input.php lib. maybe that will help?

Code:

/*
         * URL Decode
         *
         * Just in case stuff like this is submitted:
         *
         * <a href="http://www.google.com">Google</a>
         *
         * Note: Use rawurldecode() so it does not remove plus signs
         *
         */
        $str = rawurldecode($str);
