来自不同html页面的PHP连接

标签 php html mysql sql phpmyadmin

伙计们，下午好。真的感谢您在我之前的问题中的回答。它真的对我有帮助。今天我有另一个问题从不同的 html 页面访问我的变量。我希望我的表单页面与富文本框页面连接，并且从那里内容应该应用于表单页面。我尝试通过在表单页面中插入“操作”来完成此操作，但富文本框页面显示 undefined variable 。我希望任何人都可以帮助我告诉我的错误。提前致谢。

表单页面:

<?php

$option2 = $mysqli->real_escape_string($_POST['option2']);
$option3 = $mysqli->real_escape_string($_POST['option3']);
$option4 = $mysqli->real_escape_string($_POST['option4']);
$option5 = $mysqli->real_escape_string($_POST['option5']);
$option6 = $mysqli->real_escape_string($_POST['option6']);


                $sql ="INSERT INTO menubar(option1,option2,option3,option4,option5,option6)"
                ."VALUES ('$option1','$option4','$option3','$option4','$option5','$option6')";

最佳答案

存在一些语法问题。请检查下面的代码。 

  <?php
    session_start();
    $_SESSION['message'] = '';
    $mysqli=new MySQLi('127.0.0.1','root','','accounts');
    if($_SERVER["REQUEST_METHOD"] == "POST") {
        $option1 = $mysqli->real_escape_string($_POST['option1']);
        $option2 = $mysqli->real_escape_string($_POST['option2']);
        $option3 = $mysqli->real_escape_string($_POST['option3']);
        $option4 = $mysqli->real_escape_string($_POST['option4']);
        $option5 = $mysqli->real_escape_string($_POST['option5']);
        $option6 = $mysqli->real_escape_string($_POST['option6']);


        $sql = "INSERT INTO menubar(option1,option2,option3,option4,option5,option6)"
            . "VALUES ('$option1','$option4','$option3','$option4','$option5','$option6')";

        if ($mysqli->query($sql) === true) {
            $_SESSION['message'] = 'Registration successful!
                              Added $username to the database!';
            header("location:confirmnormal.php");
        } else {
            $_SESSION['message'] = "User could not be added to the database!";

        }

    }
    ?>
