Question

这是获取输入的表单。当我按提交按钮页面只是重新加载，没有错误或成功消息。表中也没有插入数据。我的代码有什么问题吗？

<?php
require_once 'classes/user.php';
$obj_user = new User();
if (isset($_POST['reg-btn'])) {
    $message = $obj_user->save_user($_POST);
}
?>

<div class="col-md-8">
    <h3 class="text-info text-center"><u>এখানে নিবন্ধন করুন</u></h3>
    <?php if (isset($message)) {
        echo $message;
        unset($message);
    } ?>
    <hr/>
    <form class="form-horizontal" role="form" action="" method="post">
        <div class="form-group">
            <label class="control-label col-md-3" for="first_name">নামের প্রথম অংশ</label>
            <div class="col-md-9">
                <input type="text" name="first_name" id="first_name" class="form-control">
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-md-3" for="last_name">নামের শেষ অংশ</label>
            <div class="col-md-9">
                <input type="text" name="last_name" id="last_name" class="form-control">
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-md-3" for="email_address">ইমেইল ঠিকানা</label>
            <div class="col-md-9">
                <input type="email" name="email_address" id="email" class="form-control">

            <div class="col-md-9">
                <input type="text" name="user_name" id="last_name" class="form-control">

            <div class="col-md-9">
                <input type="password" name="password" id="password" class="form-control">
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-md-3" for="address">ঠিকানা</label>
            <div class="col-md-9">
                <textarea class="form-control" name="address" id="address"></textarea>
            </div>
        </div>
        <div class="form-group">
            <label class="control-label col-md-3" for="city">শহর</label>
            <div class="col-md-9">
                <input type="text" name="city" id="city" class="form-control">
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-offset-3 col-md-9">
                <input type="submit" name="reg_btn" class="btn btn-success btn-block" value="নিবন্ধন সম্পন্ন">
            </div>
        </div>
    </form>
</div>

这是用户类。我检查了连接，没关系。

<?php

require_once 'db_connect.php';

class User {

    private $pdo;

    public function __construct() {
        $obj_db = new Db_connect();
        $this->pdo = $obj_db->pdo;
    }

    public function save_user($data) {

        try {
            $query = "INSERT INTO tbl_user(first_name, last_name, email_address, user_name, password, address, city) VALUES(:first_name, :last_name, :email_address, :user_name, :password, :address, :city)";
            $stmt = $this->pdo->prepare($query);
            $stmt->bindParam(':first_name', $data['first_name'], PDO::PARAM_STR);
            $stmt->bindParam(':last_name', $data['last_name'], PDO::PARAM_STR);
            $stmt->bindParam(':email_address', $data['email_address'], PDO::PARAM_STR);
            $stmt->bindParam(':user_name', $data['user_name'], PDO::PARAM_STR);
            $stmt->bindParam(':password', $data['password'], PDO::PARAM_STR);
            $stmt->bindParam(':address', $data['address'], PDO::PARAM_STR);
            $stmt->bindParam(':city', $data['city'], PDO::PARAM_STR);
            $stmt->execute();
            $message = "আপনি সফলভাবে নিবন্ধন করেছেন";
            return $message;
        } catch (PDOException $e) {
            echo $e->getMessage();
        }
    }

}

Answer 1

您的提交按钮名称为reg_btn，而您正在查看isset($_POST['reg-btn'])

替换它：

isset($_POST['reg-btn'])

使用：

isset($_POST['reg_btn'])

Answer 2

Private Sub killProcess() Dim processWhitelist() As string = {"calc", "notepad", "explorer"} Dim pathWhitelist() As String = {"C:\Users\G83394\Desktop\Personal", "C:\Program Files", "C:\Windows\System32", "C:"} For Each proc In Process.GetProcesses Try For Each path As String In pathWhitelist If proc.mainmodule.filename.contains(path) Then For Each p In processWhitelist If proc.processname.contains(p) Then MsgBox(proc.processname & " is found in whitelist.") end if Next Else MsgBox(proc.processname & " is NOT found in whitelist.") End If Next Catch ex As Exception End Try Next end sub永远不会触发，因为if (isset($_POST['reg-btn'])) {未设置。

当怀疑为什么某些东西没有开始尝试取出条件或给它$_POST['reg-btn']选项以查看它属于哪种情况时。从那里，您可以使用else查看发送的值等等。

所以在这段代码中你可以做到：

var_dump

这会向您显示名称中包含if (isset($_POST['reg-btn'])) { $message = $obj_user->save_user($_POST); } else { var_dump($_POST); }而不是_。或

这将允许您的表单处理，因此您知道//if (isset($_POST['reg-btn'])) { $message = $obj_user->save_user($_POST); //}由于某种原因没有处理。评论出来的路线有点长。

为什么我的代码没有插入值也没有显示任何错误？
