php - codeigniter form not working -


i trying create search form in codeigniter site header, everytime form submitted, receive 404 error saying page cannot found! have attempted create link test page , gave me same error.

please observe code below.

view(site_header) 

<?php echo doctype(); ?> <html lang="en">     <link href="<?php echo base_url(); ?>styles/style.css" type="text/css" rel="stylesheet"/>     <head>          <title>/title>         <div id="container">             <div id="search">                 <?php                   echo form_open('search_keyword');                  echo form_label("stumble search ", "searchfor");                  echo form_input("search","search");                  echo form_submit("getsearch","search");                  echo form_close(); ?>             </div>          </div>     </head> </html>

model (model_search)

<?php class model_search extends ci_model {      public function get_results($search_term){        $query = $this->db->query('select embed, title videos tags '%$search_term%' order rand() limit  1');       return $query->result();      } } ?>

controller (site.php) default controller

<?php   if ( ! defined('basepath')) exit('no direct script access allowed');   class site extends ci_controller {     public function index(){         $this->home();     }      public function home(){          $this->load->model("model_get");         $data["results"] = $this->model_get->getrand();         $this->load->view("site_header");         $this->load->view("site_content", $data);         $this->load->view("site_footer");     }           public function search_keyword()     {         $this->load->model('model_search');         $search_term  =  $this->input->post('search');         $data['results'] = $this->model_search->get_results($search_term);         $this->load->view('site_header');         $this->load->view('search_content',$data);         $this->load->view('site_footer');     } }  ?>

results page (search_content)

 <body>      <link href="<?php echo base_url(); ?>styles/style.css" type="text/css" rel="stylesheet"/>      <div id="container">          <div id="intro">             <?php echo heading("search results",1);?>             </div>           <div id ="content">              <p>stumble videos related <?php echo $search_term; ?> </p>              <?php              foreach ($results $row) {                  $title = $row->title;                  $vid = $row->embed;               }              echo heading($title, 3);              echo $vid;              ?>          </div>     </div> </body>

perhaps missing obvious, think may .htaccess file posted below

(.htaccess)

 <ifmodule mod_rewrite.c>     rewriteengine on     rewritebase /code/      rewritecond %{request_uri} ^system.*     rewriterule ^(.*)$ /index.php?/$1 [l]      rewritecond %{request_uri} ^application.*     rewriterule ^(.*)$ /index.php?/$1 [l]      rewritecond %{request_filename} !-f     rewritecond %{request_filename} !-d     rewriterule ^(.*)$ index.php?/$1 [l]     </ifmodule>

codeigniter urls need both controller name , method.

form_open('site/search_keyword')

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
