我正在构建一个插件，并且我想要一个子表，以便我的用户可以单击概览数据，并从那里显示数据。
按照我已经能够收集到的代码：
public function getCompanyList($idSite, $period, $date )
{
$dataTable = new Piwik_DataTable();
$query = Piwik_Query("SELECT cl.id, cl.company_name name, sf.id sf_id FROM sitedb.company_lookup cl INNER JOIN sitedb.storefronts sf ON cl.id = sf.company_id");
while ($row = $query->fetch()) {
$piwik_row = new Piwik_DataTable_Row;
$piwik_row->setSubTable( $this->getProductsForCompany($idSite, $period, $date, $row['id']) );
$piwik_row->setColumns( array('id' => $row['id'], 'Company Name' => $row['name']) );
$dataTable->addRow($piwik_row);
}
return $dataTable;
}
public function getProductsForCompany($idSite, $period, $date, $company_id )
{
if (!defined('PIWIK_ENABLE_DISPATCH')) define('PIWIK_ENABLE_DISPATCH', false);
if (!defined('PIWIK_ENABLE_ERROR_HANDLER')) define('PIWIK_ENABLE_ERROR_HANDLER', false);
require_once PIWIK_INCLUDE_PATH . "/index.php";
require_once PIWIK_INCLUDE_PATH . "/core/API/Request.php";
Piwik_FrontController::getInstance()->init();
$request = new Piwik_API_Request('
method=Actions.getActions
&idSite=' . $idSite . '
&date=' . $date . '
&period=' . $period . '
&format=PHP
&filter_column=label
&filter_pattern=product.php
&filter_sort_column=nb_visits
&filter_sort_order=desc
&token_auth=anonymous
');
$result = $request->process();
// contains an array of visits to storefront.php
$result = unserialize($result);
$query = Piwik_Query("SELECT sp.product_id id, sp.name, sp.storefront_id sf_id, cl.company_name FROM sitedb.storefront_products sp INNER JOIN sitedb.storefronts sf ON sp.storefront_id = sf.id INNER JOIN sitedb.company_lookup cl ON sf.company_id = cl.id WHERE cl.id = {$company_id}");
$dataTable = new Piwik_DataTable();
while ($row = $query->fetch()) {
// piwik returns & escaped to & -- make sure that's what you use to search!
$this->array_search_in_level("/product.php?id=" . $row['id'] . "&sf_id=" . $row['sf_id'], $result, 'label', $storefront_array, 1);
if (is_array($storefront_array) && array_key_exists('nb_visits', $storefront_array)) {
$piwik_row = new Piwik_DataTable_Row;
$piwik_row->setColumns( array('id' => $row['id'], 'Product Name' => $row['name'], 'Page Views' => $storefront_array['nb_visits']) );
$dataTable->addRow($piwik_row);
}
}
return $dataTable;
}
但是，子表永远不会出现。难道我做错了什么？
