i have made form , column in database, working fine, values , showing in textarea inside admin. issue when trying edit texts. when change value of textarea , hit save dissapears! , column in database gone.

my controller file:

admin/controller/ekomet/design.php

<?phpclass controllerekometdesign extends controller { private $error = array();  public function index() {     $this->load->language('ekomet/design');      $this->document->settitle($this->language->get('heading_title'));      $this->load->model('setting/setting');      if (($this->request->server['request_method'] == 'post') && $this->validate()) {         $this->model_setting_setting->editsetting('design_name', $this->request->post);         }      $data['button_save'] = $this->language->get('button_save');     $data['button_cancel'] = $this->language->get('button_cancel');      $data['tab_general'] = $this->language->get('tab_general');      $data['breadcrumbs'] = array();      $data['breadcrumbs'][] = array(         'text' => $this->language->get('text_home'),         'href' => $this->url->link('common/dashboard', 'token=' . $this->session->data['token'], 'ssl')     );      $data['breadcrumbs'][] = array(         'text' => $this->language->get('text_stores'),         'href' => $this->url->link('ekomet/design', 'token=' . $this->session->data['token'], 'ssl')     );      $data['breadcrumbs'][] = array(         'text' => $this->language->get('heading_title'),         'href' => $this->url->link('ekomet/design', 'token=' . $this->session->data['token'], 'ssl')     );      if (isset($this->session->data['success'])) {         $data['success'] = $this->session->data['success'];          unset($this->session->data['success']);     } else {         $data['success'] = '';     }      $data['action'] = $this->url->link('ekomet/design', 'token=' . $this->session->data['token'], 'ssl');      $data['cancel'] = $this->url->link('ekomet/design', 'token=' . $this->session->data['token'], 'ssl');      $data['token'] = $this->session->data['token'];      $settings = $this->model_setting_setting->getsetting('design_name');      if (isset($this->request->post['config_ekomet_name'])) {         $data['config_ekomet_name'] = $this->request->post['config_ekomet_name'];     } else {         $data['config_ekomet_name'] = $this->config->get('config_ekomet_name');     }      $data['header'] = $this->load->controller('common/header');     $data['column_left'] = $this->load->controller('common/column_left');     $data['footer'] = $this->load->controller('common/footer');      $this->response->setoutput($this->load->view('ekomet/design.tpl', $data)); }  protected function validate() {     if (!$this->user->haspermission('modify', 'ekomet/design')) {         $this->error['warning'] = $this->language->get('error_permission');     }      if ($this->error && !isset($this->error['warning'])) {         $this->error['warning'] = $this->language->get('error_warning');     }      return !$this->error; }}

i have looked through setting.php controller , want use setting table in database store values (no need invent wheel again). said above. pass values database. can't update it.

my template file:

admin/view/template/ekomet/design.tpl

          <div class="form-group required">             <label class="col-sm-2 control-label" for="input-ekomet-name">e-komet namn</label>             <div class="col-sm-10">               <input type="text" name="config_ekomet_name" value="<?php echo $config_ekomet_name; ?>" placeholder="<?php echo $entry_ekomet_name; ?>" id="input-ekomet-name" class="form-control" />               <?php if ($error_ekomet_name) { ?>               <div class="text-danger"><?php echo $error_ekomet_name; ?></div>               <?php } ?>             </div>           </div>

i have not made own model file because want use 1 connected setting. need make own model make work?

you using wrong prefix code , key field

make sure if code = abc key = abc_def

replace

 $this->model_setting_setting->editsetting('design_name', $this->request->post);

with

 $this->model_setting_setting->editsetting('config', $this->request->post);

so code = config , key = config_ekomet_name

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
