    $query = "SELECT supervisor.lecturerName, supervisee.studentName, supervisee.studentUniversityId FROM supervisee, supervisor WHERE supervisee.lecturerId = supervisor.lecturerId AND supervisee.studentUniversityId = '$studentUniversityId' ";

    $result = $this->db->query($query) or die($this->db->error);
    $supervisor_data = $result->fetch_array(MYSQLI_ASSOC);
    $arr = array("lecturerName", "studentName", "studentName");
    return $arr;

}

推荐答案

根据我的了解和理解(如果没有，请原谅)，您想填充文本字段 studentName 和 lecturerName 及其各自的值.对我来说，除了一件事之外，您的代码看起来是正确的.您需要删除行

From what I see and understand (please excuse if I don't), you want to populate the text fields studentName and lecturerName with their respective values. To me, you code looks correct except one thing. You need to drop the line

$arr = array("lecturerName", "studentName", "studentName");

来自 superLe.php .线

$supervisor_data = $result->fetch_array(MYSQLI_ASSOC);

已经返回一个关联数组，您可以在文件 home.php 中的变量 $ autofill 中将其用作 $ autofill ['studentName'] 或 $ autofill ['lecturerName'] .

already returns an associative array, which you can use in the variable $autofill in file home.php as $autofill['studentName'] or $autofill['lecturerName'].
