php - set values to fields in adminhtml form template -


i'd created template file admin form tab as:

class excellence_designer_block_adminhtml_designer_edit_tabs extends mage_adminhtml_block_widget_tabs {      protected function _beforetohtml() {         $this->addtab('images', array(             'label' => mage::helper('designer')->__('images'),             'title' => mage::helper('designer')->__('images'),             'content' => $this->getlayout()->createblock('designer/adminhtml_designer_edit_tab_images')->tohtml(),         ));          return parent::_beforetohtml();     }  } 
class excellence_designer_block_adminhtml_designer_edit_tab_images extends mage_adminhtml_block_template implements mage_adminhtml_block_widget_tab_interface {      public function _construct() {         parent::_construct();         $this->settemplate('designer/edit/tab/images.phtml');     }      public function gettablabel() {         return $this->__('images');     }      public function gettabtitle() {         return $this->__('images');     }      public function canshowtab() {         return true;     }      public function ishidden() {         return false;     }  }

images.phtml

<div class="input-field">     <label for="image">custom field</label>     <input type="text" class="input-text" name="image" id="image" /> </div>

but there's no value in there if want edit form

screen shot value saved in database. other tab created mage_adminhtml_block_widget_form , showing values in fields how value?

your editaction() has in way. check out.

public function editaction()         {         $newsid = $this->getrequest()->getparam('id');         $newsmodel = mage::getmodel('news/news')->load($newsid);          if ($newsmodel->getid() || $newsid == 0) {         $data = mage::getsingleton('adminhtml/session')->getformdata(true);         if (!empty($data)) {                 $model->setdata($data);             }              mage::register('news_data', $newsmodel);              $this->loadlayout();             $this->_setactivemenu('news/items');              $this->_addbreadcrumb(mage::helper('adminhtml')->__('item manager'), mage::helper('adminhtml')->__('item manager'));             $this->_addbreadcrumb(mage::helper('adminhtml')->__('item news'), mage::helper('adminhtml')->__('item news'));              $this->getlayout()->getblock('head')->setcanloadextjs(true);              $this->_addcontent($this->getlayout()->createblock('news/adminhtml_news_edit'))                  ->_addleft($this->getlayout()->createblock('news/adminhtml_news_edit_tabs'));              $this->renderlayout();          }         else             {                 mage::getsingleton('adminhtml/session')->adderror(mage::helper('news')->__('item not exist'));                 $this->_redirect('*/*/');              }        }
