php - 为什么不在此代码中插入多个数据

Question

我有一个 tbl_employee 表和 tbl_time 表，我想为出勤插入多个数据插入，但是当我单击提交按钮时，它只插入单个数据。但是问题出在哪里，帮我找出这个..这是插入代码

require './db_connect.php';
class Time extends Db_connect {

    protected $link;

    public function __construct() {
        $this->link = $this->database_connection();
    }

    public function attendance_insert($data) {
        extract($data);
        $cur_date = date('Y-m-d');

        foreach ($time_attendance as $attn_key => $attn_value) {
            if ($attn_value == 'P') {
                $SQL = "INSERT INTO tbl_time(employee_id,time_date,time_attendance)VALUES('$attn_key','$cur_date','P')";
                $atten_date=mysqli_query($this->link, $SQL);
            } else if ($attn_value == 'A') {
                $SQL = "INSERT INTO tbl_time(employee_id,time_date,time_attendance)VALUES('$attn_key','$cur_date','A')";
                $atten_date=mysqli_query($this->link, $SQL);

            }
            if ($atten_date) {
                $massage = "<div class='alert alert-success text-center'><h5>Attendance insert successfully</h5></div>";
                return $massage;
            } else {
                die('Attendance insert query problem' . mysqli_error($this->link));
            }
        }
    }
}

这是html代码

<?php

    require_once './time.php';
    $obj_time = new Time()
    $massage = '';
    if (isset($_POST['btn'])) {
        $massage = $obj_time->attendance_insert($_POST);
    }

    $employee_view = $obj_employee->employee_all_view();
    ?>
    <div class="container-fluid">
        <div class="row">
            <center>
                <a href="time.php" class="btn btn-sm btn-default glyphicon glyphicon-backward pull-left" id="show_form"></a>
                <span style="font-size:1.8em;">Attendance form</span>
            </center>
        </div>
    </div>
    <hr/>


    <?php echo $massage; ?>
    <div class="container-fluid">
        <div class="row">
            <div class="col-lg-12">

                        <?php $current_date = date('Y-M-d');
                        echo $current_date; ?>

                            while ($employee_info = mysqli_fetch_assoc($employee_view)) {
                                extract($employee_info);
                                $i++;
                                ?>

Answer 1

这个:

foreach($time_attendance as $attn_key => $attn_value){
    $SQL = "INSERT INTO tbl_time(employee_id,time_date,time_attendance) 
        VALUES('$attn_key','$cur_date','A')";
    $atten_date = mysqli_query($this->link, $SQL);

    if ($atten_date) {
        $massage = "<div class=''><h5>Attendance insert successfully</h5></div>";
        return $massage;
    }
}

如果查询成功，直接要求使用 return $massage; 中断 foreach...所以是的，您将只有一个记录。

将您的返回放在 foreach 之外。
