I'm wondering that too.
I want to search the product InternalItemID (productcode)
SS 2.3.4
mysite > page.php
/**
* Site search form
*/
function SearchForm() {
$searchText = isset($_REQUEST['Search']) ? $_REQUEST['Search'] : 'Search';
$fields = new FieldSet(
new TextField("Search", "", $searchText)
);
$actions = new FieldSet(
new FormAction('results', 'Search')
);
return new SearchForm($this, "SearchForm", $fields, $actions);
}
/**
* Process and render search results
*/
function results($data, $form){
$data = array(
'Results' => $form->getResults(),
'Query' => $form->getSearchQuery(),
'Title' => 'Search Results'
);
return $this->customise($data)->renderWith(array('Page_results', 'Page'));
}
