Tutorial 4 - Site Search


This is a short tutorial demonstrating how to add search functionality to a SilverStripe site. It is recommended that you have completed the earlier tutorials (Building a basic site, Extending a basic site, Forms), especially the tutorial on forms, before attempting this tutorial. While this tutorial will add search functionality to the site built in the previous tutorials, it should be straight forward to follow this tutorial on any site of your own.

What are we working towards?

We are going to add a search box on the top of the page. When a user types something in the box, they are taken to a results page.

Creating the search form

To enable the search engine you need to include the following code in your mysite/_config.php file. This will enable fulltext search on page content as well as names of all files in the /assets folder.


The actual search form code is already provided in FulltextSearchable so when you add the enable line above to your _config.php you can add your form as $SearchForm.

In the simple theme, the SearchForm is already added to the header. We will go through the code and explain it.

Adding the search form

To add the search form, we can add $SearchForm anywhere in our templates. In the simple theme, this is in themes/simple/templates/Includes/


	<% if $SearchForm %>
		<span class="search-dropdown-icon">L</span>
		<div class="search-bar">
	<% end_if %>
	<% include Navigation %>

Showing the results

The results function is already included in the ContentControllerSearchExtension which is applied via FulltextSearchable::enable()


	class ContentControllerSearchExtension extends Extension {
		function results($data, $form, $request) {
			$data = array(
				'Results' => $form->getResults(),
				'Query' => $form->getSearchQuery(),
				'Title' => _t('SearchForm.SearchResults', 'Search Results')
			return $this->owner->customise($data)->renderWith(array('Page_results', 'Page'));

The code populates an array with the data we wish to pass to the template - the search results, query and title of the page. The final line is a little more complicated.

When we call a function by its url (eg http://localhost/home/results), SilverStripe will look for a template with the name As we are implementing the results function on the Page page type, we create our results page template as Unfortunately this doesn't work when we are using page types that are children of the Page page type. For example, if someone used the search on the homepage, it would be rendered with rather than SilverStripe always looks for the template from the most specific page type first, so in this case it would use the first template it finds in this list:


We can override this list by using the renderWith function. The renderWith function takes an array of the names of the templates you wish to render the page with. Here we first add the data to the page by using the 'customise' function, and then attempt to render it with, falling back to if there is no

Creating the template

Lastly we need the template for the search page. This template uses all the same techniques used in previous tutorials. It also uses a number of pagination variables, which are provided by the PaginatedList class.


	<div id="Content" class="searchResults">
	    <% if $Query %>
	        <p class="searchQuery"><strong>You searched for &quot;{$Query}&quot;</strong></p>
	    <% end_if %>
	    <% if $Results %>
	    <ul id="SearchResults">
	        <% loop $Results %>
	            <a class="searchResultHeader" href="$Link">
	                <% if $MenuTitle %>
	                <% else %>
	                <% end_if %>
	            <a class="readMoreLink" href="$Link" 
	            	title="Read more about &quot;{$Title}&quot;"
	            	>Read more about &quot;{$Title}&quot;...</a>
	        <% end_loop %>
	    <% else %>
	    <p>Sorry, your search query did not return any results.</p>
	    <% end_if %>
	    <% if $Results.MoreThanOnePage %>
	    <div id="PageNumbers">
	        <% if $Results.NotLastPage %>
	        <a class="next" href="$Results.NextLink" title="View the next page">Next</a>
	        <% end_if %>
	        <% if $Results.NotFirstPage %>
	        <a class="prev" href="$Results.PrevLink" title="View the previous page">Prev</a>
	        <% end_if %>
	            <% loop $Results.Pages %>
	                <% if $CurrentBool %>
	                <% else %>
	                <a href="$Link" title="View page number $PageNum">$PageNum</a>
	                <% end_if %>
	            <% end_loop %>
	        <p>Page $Results.CurrentPage of $Results.TotalPages</p>
	    <% end_if %>
