Codeigniter-重新填充输入字段

Question

我的页面上有一些输入字段，希望在保存时重新填充。这些值被输入到数据库中，我希望这些值在输入字段中得到响应，这样用户就可以看到他们插入了什么。

查看

<div class="col-lg-1">
<label>Test1 </label>
<input type="number" name="ft_ca1[]" min="0" max="10" class="form-control input-sm rounded-0" value="<?php echo $student->ft_scores? $student->ft_scores->ft_ca1: 0; ?>">
</div>

型号

public function get_student_ftscore($subjectId,$sessionId,$sectionId,$classId,$studentId){

$sql = "SELECT mp.id, mp.student_id, mp.class_id, mp.section_id, mp.ft_ca1, mp.ft_ca2, mp.ft_ca3, mp.ft_ca4, mp.ft_ca5, mp.ft_ca6, mp.ft_project, mp.ft_affective, mp.ft_psychomotor, mp.ft_exam, mp.ft_tot_score, mp.created_at, mp.modified_at

$query = $this->db->query($sql, array($classId, $studentId, $sectionId, $subjectId, $sessionId, $classId, $studentId, $sectionId, $subjectId, $sessionId));
$result = $query->row();
return $result;

$student->ftscores = $ftscore;
$data['students'][] = $student;
}
}

我建议您使用会话保存带有输入数据的数组，然后在数据成功保存到数据库后重定向回初始页面。您应该检查您的代码点火器版本是否具有闪光消息的概念。这用于保存一些数据，仅用于在页面上以及删除之后。然后在你的表格中，你会检查数据是否设置并且不是null，如果设置了，那么就回显它。如果你只是在学习，我会建议你开始学习代码点火器4。
