The URI you submitted has disallowed characters.,CodeIgniter checks all URI segments for disallowed characters. This happens by white listing allowed characters. Which ones are allowed can be checked in /system/application/config/config.php in the $config['permitted_uri_chars'] variable. permitted_uri_chars are the characters that CodeIgniter accepts in your URI.The default value is set to something like., Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers ,When i'm trying to redirect to other website, i receive this error:

When i'm trying to redirect to other website, i receive this error:,The URI you submitted has disallowed characters.,A PHP Error was encountered,Leave blank to allow all characters -- but only if you are insane.

This is all the code i have in URI.php

private
function _detect_uri() {
   if (!isset($_SERVER['REQUEST_URI']) OR!isset($_SERVER['SCRIPT_NAME'])) {
      return '';
   }

   $uri = $_SERVER['REQUEST_URI'];
   if (strpos($uri, $_SERVER['SCRIPT_NAME']) === 0) {
      $uri = substr($uri, strlen($_SERVER['SCRIPT_NAME']));
   }
   elseif(strpos($uri, dirname($_SERVER['SCRIPT_NAME'])) === 0) {
      $uri = substr($uri, strlen(dirname($_SERVER['SCRIPT_NAME'])));
   }

   // This section ensures that even on servers that require the URI to be in the query string (Nginx) a correct
   // URI is found, and also fixes the QUERY_STRING server var and $_GET array.
   if (strncmp($uri, '?/', 2) === 0) {
      $uri = substr($uri, 2);
   }
   $parts = preg_split('#\?#i', $uri, 2);
   $uri = $parts[0];
   if (isset($parts[1])) {

   } else {

      $_GET = array();
   }

   if ($uri == '/' || empty($uri)) {
      return '/';
   }

   $uri = parse_url($uri, PHP_URL_PATH);

   // Do some final cleaning of the URI and return it
   return str_replace(array('//', '../'), '/', trim($uri, '/'));

CodeIgniter Controller :, Tags an error was encountered codeigniter disallowed characters error in codeigniter uri you submitted has disallowed characters , What is a Linux container? Linux container. ,Why we are getting this error?

For these two URLs, codeigniter complains about the blank char: "The URI you submitted has disallowed characters." ,How should I go about fixing this? ,I know I can add the blank character to the permitted_uri_chars in config.php but I'm looking for a better solution as there might be other disallowed characters in a filename.,Hope this helps you out?

I need to pass filenames via the url, e.g.:

http: //example.com/images/niceplace.jpg

The problem I'm having is when the file name contains a blank character, e.g.:

http: //example.com/images/nice place.jpg

or

http: //example.com/images/nice%20place.jpg

We’ve been using EE for several years now as our CMS of choice. However we are always stumped/frustrated by not being able to handle ‘disallowed’ characters in the URL’s better than the default CodeIgniter message.,If anyone has any suggestion how to get around this in an elegant manner - ideally a 404 redirect then we would love to find out please…,This is an archived forum and the content is probably no longer relevant, but is provided here for posterity.,It shouldn’t be too hard to make it do what you need it to by just altering where it does the show_error().  Here’s the current code:

function _filter_uri($str) {
   if ($str != '' && $this - > config - > item('permitted_uri_chars') != '' && $this - > config - > item('enable_query_strings') == FALSE) {
      // preg_quote() in PHP 5.3 escapes -, so the str_replace() and addition of - to preg_quote() is to maintain backwards
      // compatibility as many are unaware of how characters in the permitted_uri_chars will be parsed as a regex pattern
      if (!preg_match("|^[".str_replace(array('\\-', '\-'), '-', preg_quote($this - > config - > item('permitted_uri_chars'), '-')).
            "]+$|i", $str)) {
         show_error('The URI you submitted has disallowed characters.', 400);
      }
   }

   // Convert programatic characters to entities
   $bad = array('$', '(', ')', '(', ')');
   $good = array('$', '(', ')', '(', ')');

   return str_replace($bad, $good, $str);
}

Normally the second segment of the URL is reserved for the method name, but in the example above it instead has a product ID. To overcome this, CodeIgniter allows you to remap the URI handler.,To disable this functionality, you must call the method with the parameter false:,Welcome to CodeIgniter4,This would handle a resource route to the App\API\v1\Users controller with the /api/users URI.
