Silverstripe Site Search for DataObjects as Pages - Part 2 tutorial - php

Question

I made a product site at the end of last year using DataObjects as Pages - Part 2 Silverstripe, the site is live now, and I need to implement a site search function for the site.
I implemented a search function like Tutorial 4 - Site Search however this doesn't work with the product search since each product is a dataobject rather than a page.
Can anyone shed some light on how I can make the site search work for the products?
I know there is a tutorial 3 DataObject as Pages I tried it but it messed up all my existing products as well as some additional existing functions for the products. Someone suggested http://silverstripe.org/all-other-modules/show/6641?start=24 but unsuccessful so far.
Any help on how to do the search function for the products is appreciated.
Thanks.
Here is my Product.php code
<?php
class Product extends DataObject
{
static $db = array(
'Title' => 'Varchar(255)',
'Description' => 'HTMLText',
'Price' => 'Decimal(6,2)',
'URLSegment' => 'Varchar(255)'
);
//Set our defaults
static $defaults = array(
'Title' => 'New Product',
'URLSegment' => 'new-product'
);
static $has_one = array(
'Image' => 'Image',
'PDF' => 'File'
);
//Relate to the category pages
static $belongs_many_many = array(
'Categories' => 'CategoryPage'
);
//Fields to show in ModelAdmin table
static $summary_fields = array(
'Title' => 'Title',
'URLSegment' => 'URLSegment',
'Price' => 'Price (£)'
);
//Add an SQL index for the URLSegment
static $indexes = array(
"URLSegment" => true
);
//Fields to search in ModelAdmin
static $searchable_fields = array (
'Title',
'URLSegment',
'Description',
'Categories.ID' => array(
'title' => 'Category'
)
);
function getCMSFields()
{
$fields = parent::getCMSFields();
//Main Tab
$fields->addFieldToTab("Root.Main", new TextField('Title', 'Title'));
$fields->addFieldToTab("Root.Main", new TextField('URLSegment', 'URL Segment'));
$fields->addFieldToTab("Root.Main", new NumericField('Price'));
$fields->addFieldToTab("Root.Main", new HTMLEditorField('Description'));
//added below for the ordering
$Categories = DataObject::get('CategoryPage');
$map = $Categories->map('ID', 'CheckboxSummary');
asort($map);
$fields->addFieldToTab("Root.Categories", new CheckboxsetField('Categories', 'Categories', $map));
//Images
$fields->addFieldToTab("Root.Images", new ImageField('Image', 'Image', Null, Null, Null, 'Uploads/category_banners'));
$fields->addFieldToTab("Root.Files", new FileIFrameField('PDF'));
return $fields;
}
//Set URLSegment to be unique on write
function onBeforeWrite()
{
// If there is no URLSegment set, generate one from Title
if((!$this->URLSegment || $this->URLSegment == 'new-product') && $this->Title != 'New Product')
{
$this->URLSegment = SiteTree::generateURLSegment($this->Title);
}
else if($this->isChanged('URLSegment'))
{
// Make sure the URLSegment is valid for use in a URL
$segment = preg_replace('/[^A-Za-z0-9]+/','-',$this->URLSegment);

}
$this->URLSegment = $segment;
}
// Ensure that this object has a non-conflicting URLSegment value.
$count = 2;
while($this->LookForExistingURLSegment($this->URLSegment))
{
$this->URLSegment = preg_replace('/-[0-9]+$/', null, $this->URLSegment) . '-' . $count;
$count++;
}
parent::onBeforeWrite();
}
//Test whether the URLSegment exists already on another Product
function LookForExistingURLSegment($URLSegment)
{
return (DataObject::get_one('Product', "URLSegment = '" . $URLSegment ."' AND ID != " . $this->ID));
}
//Generate the link for this product
function Link()
{
//if we are on a category page return that
if(Director::CurrentPage()->ClassName == 'CategoryPage')
{
$Category = Director::CurrentPage();
}
//Otherwise just grab the first category this product is in
else

{
//If the current StaffMember is the same as this return 'current' class
return ($Product->ID == $this->ID) ? 'current' : 'link';
}
}
}
}
and here is my CategoryPage.php
<?php

return $fields;
}
//important for sidebar showing, this is sitetree stuff - relationship between categories and products 20012012

If you are doing any serious search stuff, the built-in search functionality (based on MySQL MyISAM) is not ideal. I'd suggest to use Solr or Sphinx, integrated into SilverStripe with https://github.com/silverstripe/silverstripe-sphinx or https://github.com/nyeholt/silverstripe-solr (I'd start off with the first one). This will also index DAOs.
