PHP code

                                       
                    
  
  
                
   " .$html->link(sprintf(__('Edit %s', true), $singularHumanName), array('action' => 'edit', ${$singularVar}[$modelClass][$primaryKey])). " \n";                    echo "\t\t
   
   
" .$html->link(sprintf(__('Delete %s', true), $singularHumanName), array('action' => 'delete', ${$singularVar}[$modelClass][$primaryKey]), null, __('Are you sure you want to delete', true).' #' . ${$singularVar}[$modelClass][$primaryKey] . '?'). " 
\n";                    echo "\t\t
   
   
" .$html->link(sprintf(__('List %s', true), $pluralHumanName), array('action' => 'index')). " 
\n";                    echo "\t\t
   
   
" .$html->link(sprintf(__('New %s', true), $singularHumanName), array('action' => 'add')). " 
\n";
