Controller:

i cant able to reach this function and i got an error

An Error Was Encountered The URI you submitted has disallowed characters.

So, how to pass form data in controller using GET method? thanx in advance.

Answer 1

View:

<form action="<?=site_url('controller_name/function_name);?>" method="get">
    <input type="text" name="temp">
    <input type="submit"/>
</form>

Controller

class controller_name extends CI_Controller{

   function function_name(){
      echo $this->input->get('temp');
   }

}

Answer 2

parse_str($_SERVER['QUERY_STRING'],$_GET);

在将以下行添加到applications / config / config.php后，仅对我有用：

$config['uri_protocol'] = "PATH_INFO";

Answer 3

To solve the error go to this line . I personally think, that this is a mistake by design, because black-listing symbols from URI would be much better then white-listing.

As for GET variables .. you would have to use <form method="get" action="/what/ever/"> .

Answer 4

你不能用$ this-> input-> get（'temp'）;
