Question

我有一个数据库，其中有4个表，2个用于私人用户，2个用于业务用户。出于某种原因，当我尝试使用业务用户的电子邮件登录时它不起作用但用户名工作，并且在私有表中它可以工作，这是我的代码如果我没有正确解释它告诉我并且我尽力解释它再次

    $password = $_POST['password'];
    $emailuser = $_POST['unameemail'];
    $password = mysqli_real_escape_string($sql , $password); 
    $emailuser = mysqli_real_escape_string($sql , $emailuser); 
    $pwcheck = "
    SELECT * FROM private AS p 
    INNER JOIN user_private_data 
    AS c ON p.id = c.id 
    WHERE username='$emailuser' OR email='$emailuser'"; // part that works fine 
    $resultcheck = mysqli_query($sql , $pwcheck); // part that works fine 
    $rowcheck = mysqli_fetch_array($resultcheck , MYSQLI_ASSOC); // part that works fine 
    $hash = $rowcheck['password']; // part that works fine 
    $hash_pwd = password_verify($password , $hash);
    if ($hash_pwd != 0) {
        $_SESSION['username'] = $rowcheck['username']; // part that works fine  
        $_SESSION['logged'] = true; // part that works fine 
        header("refresh:0;url=../blablabla.php");     // part that works fine                   
    } else {
        $privateuser = "
        SELECT * FROM business AS d 
        INNER JOIN user_business_data 
        AS j ON d.id = j.id 
        WHERE username='$emailuser' OR email='$emailuser'"; // doesn't work
        $resultprivate = mysqli_query($sql , $privateuser); // doesn't work
            $rowprivate = mysqli_fetch_array($resultprivate , MYSQLI_ASSOC);
        $hashprivate = $rowprivate['password'];
        $hash_private = password_verify($password , $hashprivate);
        if ($hash_private != 0) {

            $_SESSION['username'] = $rowprivate['username'];
            $_SESSION['logged'] = true;
            $_SESSION['business'] = $rowprivate['bname'];
            $_SESSION['type'] = 'business';
}

试试这个：你需要在获取之前检查查询是否确实有结果我假设你的连接中定义了变量$ sql

<?php

$password = $_POST['password'];
$emailuser = $_POST['unameemail'];
$password = mysqli_real_escape_string($sql, $password);
$emailuser = mysqli_real_escape_string($sql, $emailuser);
$pwcheck = "
            SELECT * FROM private AS p 
            INNER JOIN user_private_data 
            AS c ON p.id = c.id 
            WHERE username='$emailuser' OR email='$emailuser'"; // part that works fine 
$resultcheck = mysqli_query($sql, $pwcheck); // part that works fine 
$rowcheck = mysqli_fetch_array($resultcheck, MYSQLI_ASSOC); // part that works fine 
$hash = $rowcheck['password']; // part that works fine 
$hash_pwd = password_verify($password, $hash);
if ($hash_pwd != 0) {
    $_SESSION['username'] = $rowcheck['username']; // part that works fine  
    $_SESSION['logged'] = true; // part that works fine 
    header("refresh:0;url=../blablabla.php");     // part that works fine                   
} else {
    $privateuser = "
                SELECT * FROM business AS d 
                INNER JOIN user_business_data 
                AS j ON d.id = j.id 
                WHERE username='$emailuser' OR email='$emailuser'"; // doesn't work
    $resultprivate = mysqli_query($sql, $privateuser); // doesn't work
    if ($resultprivate->num_rows > 0) {
        $rowprivate = mysqli_fetch_array($resultprivate, MYSQLI_ASSOC);
        $hashprivate = $rowprivate['password'];
        $hash_private = password_verify($password, $hashprivate);
        if ($hash_private != 0) {

            $_SESSION['username'] = $rowprivate['username'];
            $_SESSION['logged'] = true;
            $_SESSION['business'] = $rowprivate['bname'];
            $_SESSION['type'] = 'business';
        } else {
            //no record
        }
    }
?>
