当我完成3个用户信息表格时，我将它们存储在会话数组中，第三步之后，我想从数据库中的数组中添加全部信息。但是当我单击“提交”按钮时，我的数据库正在填充仅具有ID且没有数据。

session_start();
$userinfo=array();
$userinfo['fname']=$_POST['Fname'];
$userinfo['mname']=$_POST['Mname'];
$userinfo['lname']=$_POST['Lname'];
$userinfo['login']=$_POST['login'];
$userinfo['email']=$_POST['email'];
$userinfo['phone']=$_POST['phone'];
$_SESSION['userinfo']=$userinfo;

这是第一个数组，与其他2个数组一样。

Answer 1

您使用的是indexes(0,1,2,....)而不是(fname, mname, lname,....)。因此，您应该在

之后更新行

$sql = "INSERT INTO users (user_fname,user_mname,user_lname,user_login,user_email,user_phone) VALUES ('{$_SESSION['userinfo'][0]}','{$_SESSION['userinfo'][1]}','{$_SESSION['userinfo'][2]}','{$_SESSION['userinfo'][3]}','{$_SESSION['userinfo'][4]}','{$_SESSION['userinfo'][5]}')";

使用

$sql = "INSERT INTO users (user_fname,user_mname,user_lname,user_login,user_email,user_phone) VALUES ('{$_SESSION['userinfo']['fname']}','{$_SESSION['userinfo']['mname']}','{$_SESSION['userinfo']['lname']}','{$_SESSION['userinfo']['login']}','{$_SESSION['userinfo']['email']}','{$_SESSION['userinfo']['phone']}')";

Answer 2

您的第一个查询中存在语法错误，您丢失了{，该'$_SESSION['userinfo'][0]}',应该是'{$ _SESSION ['userinfo'] [0]}'。

另外，考虑从变量中删除索引； '{$_SESSION['userinfo'][0]}'.至'{$_SESSION['userinfo']}'。

Answer 3

您正在发送错误的信息作为值。例如，您应该编写VALUES ('{$_SESSION['userinfo']['fname']}',... inted of

VALUES ('$_SESSION['userinfo'][0]}','{$_SESSION['userinfo'][1]}','{$_SESSION['userinfo'][2]}','{$_SESSION['userinfo'][3]}','{$_SESSION['userinfo'][4]}','{$_SESSION['userinfo'][5]}')"

Answer 4

$ _ SESSION 这是一个“超全局变量”，即自动全局变量。这仅表示它在整个脚本的所有作用域中均可用。不需要做全局变量。在函数或方法中访问它。

<?php
       include 'connection.php';
        session_start();
        $noteinfo=array();
        $noteinfo['note']=$_POST['note'];
        $_SESSION['noteinfo']=$noteinfo;

    if (isset($_POST['submit'])) {
        if (empty($_POST['note'])) {
            echo "Dobavete Komentar";
        }if (!empty($_SESSION['noteinfo'])) {
            $check=mysqli_escape_string($conn,$_SESSION['userinfo']['fname']);

$sql = "INSERT INTO users (user_fname,user_mname,user_lname,user_login,user_email,user_phone) VALUES ('{$_SESSION['userinfo']['fname']}','{$_SESSION['userinfo']['mname']}','{$_SESSION['userinfo']['lname']}','{$_SESSION['userinfo']['login']}','{$_SESSION['userinfo']['email']}','{$_SESSION['userinfo']['phone']}')";
           $sql1 = "INSERT INTO addresses (address_line_1,address_line_2,address_zip,address_city,address_province,address_country) VALUES ('$_SESSION[adr1]','$_SESSION[adr2]','$_SESSION[zip]','$_SESSION[city]','$_SESSION[provinciq]','$_SESSION[durjava]')";
           $sql2="INSERT INTO notes (note_text) VALUES ('$_SESSION[note]')";
            if (mysqli_query($conn,$sql)) { echo "Added"; if (mysqli_query($conn,$sql1)) { echo "Added"; if (mysqli_query($conn,$sql2)) { echo "Added"; header("refresh:3 ; url=profile.php"); }
            } }else{ echo "Error"; }
          } else{

    header("refresh:1 ; url=zapiski.php");
}
        }
