<?define('IN_ECS', true);require(dirname(__FILE__) . '/includes/init.php');require_once(ROOT_PATH . 'includes/gain_init.php');/*------------------------------------------------------ */

$user_id = isset($_SESSION['user_id']) ? $_SESSION['user_id'] : 0;
$user_name = isset($_SESSION['user_name']) ? $_SESSION['user_name'] : 0;$action  = isset($_REQUEST['act']) ? trim($_REQUEST['act']) : 'default';
$gi = &new gain();assign_template();$position = assign_ur_here();$smarty->assign('page_title', $position['title']);    // 页面标题
$smarty->assign('keywords',    htmlspecialchars($position['title']));
$smarty->assign('description', htmlspecialchars($position['title']));//第一个参数为分类id,第二个为显示记录数
$gain_adcpa_rs = $gi->get_gain_list_by_catid(1,6);
//不足6个记录时数据用0补齐
$gain_adcpa_rs = array_pad($gain_adcpa_rs,6,0);//第一个参数为分类id,第二个为显示记录数
$gain_adfaq_rs = $gi->get_gain_list_by_catid(3,6);$gain_adfaq_rs = array_pad($gain_adfaq_rs,6,0);
//$gain_adcps_rs = $gi->get_gain_list_by_catid(2,6);//$gain_adcps_rs = array_pad($gain_adcps_rs,6,0);
$smarty->assign('gain_adcpa_rs', $gain_adcpa_rs);

  为什么显示assign('page_title', $position['title']);    // 页面标题
$smarty->assign('keywords',    htmlspecialchars($position['title']));
$smarty->assign('description', htmlspecialchars($position['title']));//第一个参数为分类id,第二个为显示记录数
$gain_adcpa_rs = $gi->get_gain_list_by_catid(1,6);
//不足6个记录时数据用0补齐
$gain_adcpa_rs = array_pad($gain_adcpa_rs,6,0);//第一个参数为分类id,第二个为显示记录数
$gain_adfaq_rs = $gi->get_gain_list_by_catid(3,6);$gain_adfaq_rs = array_pad($gain_adfaq_rs,6,0);
//$gain_adcps_rs = $gi->get_gain_list_by_catid(2,6);//$gain_adcps_rs = array_pad($gain_adcps_rs,6,0);
$smarty->assign('gain_adcpa_rs', $gain_adcpa_rs);
$smarty->assign('gain_adfaq_rs', $gain_adfaq_rs);//第一个参数为分类id,第二个为显示记录数$gain_adclick_rs = $gi->get_gain_ad_position(1,6);
