Question

我有一个登录表单（index.php），允许学生访问他们的门户网站，学生＆＃39;然后检查注册号和密码是否插入（login.php）并进入类（StudentLogin.php），如果所有凭据都与数据库中的凭据匹配，则允许学生访问其门户。在输入正确的凭据后，该流程不会继续执行stud_page.php .....我会感谢您对此事的任何帮助，我不了解正在发生的事情。

下面是index.php：

＆＃13;

      <?php

    require("../admin/database.php");
    require("../class/StudentLogin.php");

    if(isset($_POST['submit'])){
      $regnum = trim($_POST['regnumber']);
      $password = trim($_POST['password']);

      $loginStud = new StudentLogin($reg_num, $password);
      $rtnlogin = $loginStud->Studlogin();
    }

    $conn->close();

    ?>

Then the StudentLogin class is:

    <?php

class StudentLogin
{
  private $_regnumber;
  private $_password;

  public function __construct($c_reg_num, $c_password){
    $this->_regnumber = $c_reg_num;
    $this->_password = $c_password;
  }

  public function StudLogin(){
    global $conn;
    //  starting session
    session_start();
     // valiidate errors
    $error_msg_array = array();
    // error msg
    $error_msg = FALSE;

    if($this->_reg_num == ""){
      $error_msg_array[] = "Please input your Registration Number";
      $error_msg = TRUE;
    }
    if($this->_password == ""){
      $error_msg_array[] = "Please input your password";
      $error_msg = TRUE;
    }
    if($error_msg){
      $_SESSION['ERROR_MSG_ARR'] = $error_msg_array;
      header("location: http://localhost/project/index.php");
      exit();
    }
    $sql = "SELECT * FROM students WHERE regnumber ='$reg_num' AND password ='$password' LIMIT 1";
    if(!$stmt = $conn->prepare($sql)){
      echo $stmt->error;
    } else {
      $stmt->bind_param("ss", $this->_reg_num, $this->_password);
      $stmt->execute();
      $result = $stmt->get_result();
    }
    if($result->num_rows > 0) {
       // login successful
      $row = $result->fetch_assoc();

      // session creation
      session_regenerate_id();
      $_SESSION['reg_num'] = $row["regnunmber"];
      $_SESSION['name'] = $row["name"];
      session_write_close();
      header("location: http://localhost/project/stud_page.php");

    } else {
       // Login failed
      $error_msg_array[] = "The Registration Number and Password you entered is incorrect.";
      $error_msg = TRUE;
      if($error_msg) {
        $_SESSION['ERROR_MSG_ARR'] = $error_msg_array;
        header("location: http://localhost/project/index.php");
        exit();
      }
      $stmt->free_result();
    }
    $result->free();
    return $result;
  }
}
?>

＆＃13;

login.php如下：

students

MySQL数据库，表$sql="INSERT INTO `students`(`name`, `education`, `regnumber`, `nationality`, `gender`, `phone`, `photo`, `branch`,`password`) VALUES ('$name','$education','$reg_num','$nationality','$gender','$phone','$target_file','$branch','$ency_pass')";包含以下列：

web:
  image: nginx:latest
  ports:
    - "8080:80"
    - "8000:8000"
  volumes:
    - ./code:/code
    - ./site.conf:/etc/nginx/conf.d/site.conf
  links:
    - php
    - dynamodb:db // <-- Probably unnecessary, requires more testing
php:
  build: php/
  volumes:
    - ./code:/code
  links:
    - dynamodb // <-- Important
dynamodb:
  build: dynamodb/
  expose:
    - 8000

您在login.php上有验证，在发送表单之前未加载。如果你能，我会建议你使用dibi，因为这与数据库的工作不正确，如果你打算在生产中使用它会导致一些问题 https://dibiphp.com/en/

表格未能继续提交
