find( string $type 'first' , array $query array() )

Queries the datasource and returns a result set array.

Also used to perform notation finds, where the first argument is type of find operation to perform (all / first / count / neighbors / list / threaded), second parameter options for finding ( indexed array, including: 'conditions', 'limit', 'recursive', 'page', 'fields', 'offset', 'order')

Eg:

find('all', array(                'conditions' => array('name' => 'Thomas Anderson'), 'fields' => array('name', 'email'), 'order' => 'field3 DESC', 'recursive' => 2, 'group' => 'type' ));

In addition to the standard query keys above, you can provide Datasource, and behavior specific keys. For example, when using a SQL based datasource you can use the joins key to specify additional joins that should be part of the query.

find('all', array(                'conditions' => array('name' => 'Thomas Anderson'), 'joins' => array( array( 'alias' => 'Thought', 'table' => 'thoughts', 'type' => 'LEFT', 'conditions' => '`Thought`.`person_id` = `Person`.`id`' ) ) )); 代码示例：

$pv_count = $this->page_visit->findCount("page_visit.session_id='{$_session_id}' and page_visit.ip='{$ip}' and page_visit.url='{$_url}'"); $time = time(); $pv_new_insert = true; if ($pv_count > 0) {
       $pv = $this->page_visit->find('all', array(         'conditions' => array('session_id' => $_session_id, 'ip'=>$ip, 'url'=>$_url),         'fields' => array('*'),         'order' => 'time_start DESC',         'limit'=>1     ));     $obj = $pv[0]["page_visit"];     $old_time_start = intval($obj['time_start']);     $sux = $time - $old_time_start;     $interval = $time - $pv['time_start'];     if ($sux > 3600) {
           //超过一个小时后就算是新的访问记录     } else {
           //一小时之内的刷新页面，只更新记录的更改时间         $pv_new_insert = false;         $obj['updated'] = $time;         $this->page_visit->save($obj);     } } if ($pv_new_insert) {//新增用户访问页面的记录     $pageVisit = Array();     $pageVisit['session_id'] = $_session_id;     $pageVisit['ip'] = $this->User->getip();     $pageVisit['url'] = $_url;     $pageVisit['time_start'] = $time;     $pageVisit['created'] = $time;     $pageVisit['updated'] = $time;     $pageVisit['device'] = $device . $_SERVER['HTTP_USER_AGENT'];     $this->page_visit->save($pageVisit); }
