Question

我目前正在创建一个网页，页面上的管理员可以生成特定数量的新用户（具体取决于订单）。现在，添加新用户的功能（1-many）正在运行。虽然当我创建新成员时，他们没有独特的“随机”内容。在同一生成下创建的所有用户都具有相同的。

admin.php （带有表单和函数的代码）

<head>
  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">

<?php
include('template.php');
if(isset($_POST['email']))            //inkluderar template och hämtar inlogg//
{
$characters = "0123456789abcdefghijklmnopqrstuvwxyz";

function genRandomString($length = 10) {
    $characters ='0123456789abcdefghijklmnopqrstuvwxyz';
    $string = '';
    for ($p = 0; $p < $length; $p++) {
    $string .= $characters[mt_rand(0, strlen($characters))];        //funktion för slumpmässig kod//
    }
    return $string;
}
  $courseID = '1';
  $antal = $_POST['antal'];
  $role = '3'; //Detta gör att användaren som skapas får rollvärdet 3//*
  $password = genRandomString();//genererar slumpmässig kod för licens och lösenord//
  $licenseID = genRandomString();



mysql_query('SET character_set_results=utf8');
mysql_query('SET names=utf8');

所以，我的问题，您是否知道如何创建一个创建唯一许可证和密码的循环？

Answer 1

根据当前代码，修复是，您需要在循环内调用genRandomString函数。

for ($tmp = 1; $tmp <= $antal; $tmp++) {
    $password = genRandomString();
    $licenseID = genRandomString();
    $query = <<<END

    INSERT INTO user(email, company, courseID, password, licenseID, role)   
    VALUES('{$_POST['email']}','{$_POST['company']}', '$courseID', '$password','$licenseID', '$role');  


END;

    //För in data från formuläret till databasen via poster.//

    $mysqli->query($query) or die(mysql_error());
}

如果你想要一个非可重复的字符串，那么试试

function genRandomString($length = 10) {

    $string = md5(microtime());

    return $string;
}

为每个循环创建唯一的许可证ID和密码
