php - Passing JSON data from Controller to Model -

-

i have following codeigniter application, in trying read external json file in controller, , pass model function getkey(), , finally, pass data returned function view. keep getting error message "php parse error: syntax error, unexpected '$this' (t_variable), expecting function (t_function)" , unsure of causing it. new using codeigniter, appreciated.

my controller:

class test extends ci_controller{     public function __construct(){         parent::__construct();     }      var $test_id = 1;     var $json_key;     $this->load->model('test_model');      $json_key = $this->test_model->getkey($test_id);     $json_key = json_decode($json_key);     $data['test_key'] = $json_key;      $this->load->view('test_view', $data); }

my model:

class test_model extends ci_model{     var $image_array = array();     var $test_key = array();     var $test_name = '';      public function __construct(){         parent::__construct();     }      public function getkey($test_id){         switch($test_id){             case 1:                 $test_name = "sample1";                 break;             case 2:                 $test_name = "sample2";                 break;             case 3:                 $test_name = "sample3";                 break;         }          $image_array = file_get_contents('../files/' . $$test_name . '_key.json');         $test_key = shuffle($image_array);          return $image_array;     } }

my view:

<html>   <head>     <title>test</title>   </head>   <body>     <h1>test screen</h1>     <?php print_r($test_key); ?>     <?php print_r($json_key); ?>   </body> </html>

thanks ahead of time.

your controller wrong. code should in function. this:

class test extends ci_controller {   public function __construct()   {     parent::__construct();   }    function index()   {     $this->load->model('test_model');      $test_id = 1;     $json_key = $this->test_model->getkey($test_id);     $json_key = json_decode($json_key);     $data['test_key'] = $json_key;      $this->load->view('test_view', $data);   } }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
