Question

Codeigniter查询数组忽略第一行但显示其余行，这可能是什么原因??? ...

function index() {
$date = date('Y-m-d');
/* $result = $this->smsgateway->SendAbsentSMS(date('Y-m-d', $this->customlib->datetostrtotime($date))); */
$student = $this->stuattendence_model->student_daily_attendance($date);
print_r($student);
}

public function student_daily_attendance($date) {
     $this->db->select('students.id,students.firstname,students.lastname,students.guardian_phone,students.roll_no,classes.id,classes.class,sections.id,sections.section,student_attendences.*,student_session.id,student_session.class_id,student_session.section_id,student_session.session_id');
    $this->db->from('students');
    $this->db->join('student_session', 'student_session.student_id = students.id');
    $this->db->join('classes', 'classes.id = student_session.class_id');
    $this->db->join('sections', 'sections.id = student_session.section_id');
    $this->db->join('student_attendences', 'student_attendences.student_session_id = students.id');
    $this->db->where('date', $date);
    $query = $this->db->get();
        return $query->result_array();
    }

function index() {
$date = date('Y-m-d');
/* $result = $this->smsgateway->SendAbsentSMS(date('Y-m-d', $this->customlib->datetostrtotime($date))); */
$student = $this->stuattendence_model->student_daily_attendance($date);
print_r($student);
}

public function student_daily_attendance($date) {
     $this->db->select('students.id,students.firstname,students.lastname,students.guardian_phone,students.roll_no,classes.id,classes.class,sections.id,sections.section,student_attendences.*,student_session.id,student_session.class_id,student_session.section_id,student_session.session_id');
    $this->db->from('students');
    $this->db->join('student_session', 'student_session.student_id = students.id');
    $this->db->join('classes', 'classes.id = student_session.class_id');
    $this->db->join('sections', 'sections.id = student_session.section_id');
    $this->db->join('student_attendences', 'student_attendences.student_session_id = students.id');
    $this->db->where('DATE(date)', $date);
    $query = $this->db->get();
        return $query->result_array();
    }

只需更改此类查询的位置$ this-＆gt; db-＆gt; where（＆＃39; DATE（date）＆＃39;，$ date）;

道歉，数据库表记录了我删除的学生，因此显示的记录少了一个。

Codeigniter查询数组不显示第一条记录，但显示其他记录
