我在PHP中使用蒙戈DB驱动程序类像如何过滤PHP中的数据Mongo DB驱动程序使用或条件?
public function fetchStudentsForBroadcast()
{
$this->collection = $this->db->studentTbl;
$batch = (int)$this->batch;
$course = $this->course;
$year = $this->academicyear;
$projection = array("student_id" => 1,"roll_no" => 1,"uploads.profile_pic"=> 1,
"first_name" => 1,"middle_name"=>1,"last_name"=>1,"email"=>1,
"registration_temp_perm_no"=>1,"dob"=>1,"gender"=>1,"guardian_name"=>1);
if ($course != "Select")
$orcourse = array('$and' => array(array("batchhistory.course" => new MongoRegex("/$course/i"))));
else
$orcourse = array('$and' => array(array("batchhistory.course" => new MongoRegex("/$empty/i"))));
if ($batch != "Select")
$orbatch = array('$and' => array(array("batchhistory.batchid" => new MongoRegex("/$batch/i"))));
else
$orbatch = array('$and' => array(array("batchhistory.batchid" => new MongoRegex("/$empty/i"))));
if ($year != "Select")
$oryear = array('$and' => array(array("batchhistory.academic_year" => new MongoRegex("/$year/i"))));
else
$oryear = array('$and' => array(array("batchhistory.academic_year" => new MongoRegex("/$empty/i"))));
$query = array('$and' => array($and, $orbatch, $orcourse, $oryear));
// $query = array('batchhistory.course'=>''.$course.'' , 'batchhistory.batchid'=>$batch , 'batchhistory.academic_year'=>''.$year.'','is_active'=>1,'has_finished'=>0);
$cursor = $this->collection->find($query,$projection);
return $cursor;
}
其实我试图弄清楚如何筛选在PHP MongoDB的驱动程序写入数据的功能。如果$ course包含'Select'以外的内容,那么过滤应该基于$ course,如果$ course和$ batch包含'Select'以外的值,那么过滤应该基于$ course和$ batch。如果所有三个都包含“Select”以外的值,则过滤应基于所有三个值。
上述代码无法正常工作。
请帮忙!!!
