**calling function in jobs/index.tpl **

    function jobsearch()     {          var form=$("#jobsearchform")               //$("#result").html("<img alt="ajax search" src='ajax-loader.gif'/>");           $.ajax({                 type: 'post',                 url: '/jobs/processjobsearch/',                 data: form.serialize(),                 success: function(data){                 alert(data);                   //document.getelementbyid("display").innerhtml = data;                              $.each(data, function(index, value) { alert(value);                                      $.each(value, function(index, value) {                                        $("#data").append("<tr><td>" + value + '</td></tr>');                                 });                                 });                                      }                    });      } //accessing value  <?php echo $errormsg; ?> //this gives me output if called index()             //but doesn't give output when called processjobsearch() 

global view

class view {     protected $_file;     protected $_data = array();      public function __construct($file)     {         $this->_file = $file;     }    public function assign($variable , $value)         {         $this->data[$variable] = $value;         }     public function set($key, $value)     {          $this->_data[$key] = $value;     }      public function get($key)     {       return $this->_data[$key];     }      public function output()     {         if (!file_exists($this->_file))         {             throw new exception("view " . $this->_file . " doesn't exist.");         }          extract($this->_data);         ob_start();         include($this->_file);         $output = ob_get_contents();         ob_end_clean();         echo $output;     } } 

global controller

 class controller     {         protected $_model;         protected $_controller;         protected $_action;         protected $_view;         protected $_modelbasename;           protected $cookname;         //protected $_data = array();          public function __construct($model, $action)         {              $this->_controller = ucwords(__class__);             $this->_action = $action;             $this->_modelbasename = $model;              $this->_view = new view('views' . ds . strtolower($this->_modelbasename) . ds . $action . '.tpl');         }          protected function _setmodel($modelname)         {             $modelname .= 'model';             $this->_model = new $modelname();         }          protected function _setview($viewname)         {             $this->_view = new view('views' . ds . strtolower($this->_modelbasename) . ds . $viewname . '.tpl');         }         public function _seterror($errorcode)         {  //echo "pass1";          $errormsg = $this->_model->geterror($errorcode); //echo $errormsg [jserr_msg];           return $errormsg [jserr_msg];           } }    

jobscontroller

class jobscontroller extends controller  {     public function __construct($model, $action)     {         parent::__construct($model, $action);         $this->_setmodel($model);     }          public function index()     {           $this->_view->set('title', 'job search');                   $script2 = base_front.'js/jquery-1.11.3.min.js';              $script4 = base_front.'js/scw.js';               $js_global = array( $script2, $script4);        $this->_view->set('js_global', $js_global);      $errormsg =  $this->_seterror('f_001');        $this->_view->set('errormsg', $errormsg);    //in index function works           return $this->_view->output();     }     /**     * defines processjobsearch, called jobs/index.tpl file     * process value search getjobsearchdata function in jobsinmodel relative detail.     */     public function processjobsearch() {  try {        $valtosearch = isset($_post['keyword']) ? trim($_post['keyword']) : null;         $nature = isset($_post['nature']) ? trim($_post['nature']) : null;         $jobs = $this->_model->getjobsearchdata($valtosearch, $nature);           // print_r($jobs);     $errormsg =  $this->_seterror('f_001');      $this->_view->set('errormsg', $errormsg); //here doesn't works     $this->_view->set('jobs', $jobs);        // return $this->_view->output();        } catch (exception $e) {         echo '<h1>application error:</h1>' . $e->getmessage();     }           }  } 

the _seterror() method not defined in controller or jobscontroller. shouldn't work in either index() or processjobsearch() methods.

i assume want (although i'm not sure why):

class controller {     //...      protected function _seterror($errorcode) {         //do code produce message??         return $errormsg;     } } 

edit:

ah okay, see you're doing now. variable $errormsg in jobs/index.tpl fulfilled view::output() method. js (being client side) cannot update php variable, need grab value via ajax , populate html element containing value.

i can see js code trying populate table cell with result of processjobsearch() (via ajax), nothing returned method. you're adding data view, not outputting it.

perhaps, rather jobs/processjobsearch.tpl, use jobs/processjobsearch.json , populate view data. grab data via ajax , use js change error message.

something this:

function jobsearch() {     var form=$("#jobsearchform")     //$("#result").html("<img alt="ajax search" src='ajax-loader.gif'/>");     $.ajax({         type: 'post',         url: '/jobs/processjobsearch/',         data: form.serialize(),         success: function(data){             var json = $.parsejson(data);              $.each(json.jobs, function(index, value) { alert(value);                 $.each(value, function(index, value) {                     $("#data").append("<tr><td>" + value + '</td></tr>');                 });             });              $('#errorr-msg').html(json.errormsg);         }     }); }
