php - 在 php 中使用用户名为用户创建目录

Question

我想通过每个用户自己的用户名创建目录，我已经编写了这段代码

<?php
if (!file_exists(ROOT_PATH.'user/upload/[User Name]/avatar/big')) {
    mkdir(ROOT_PATH.'user/upload/[User Name]/avatar/big', 0777, true);
}
?>

我想用用户的用户名替换[用户名]。

在我的 MySQL 数据库用户名列中是 UserName。

这是web.config.php文件内容

添加头像路径在第 16 节中。

这样的东西就是你所追求的。它将为您提供足够的信息来开始使用，但您需要研究设置新的 PDO 部分并修改查询以匹配您正在寻找的内容:

<?php
    $db = new PDO("..."); // Connection details here
    $stmt = $db->prepare("SELECT * from some_table where user_id = :id"); // Finds the information based on an ID. Change this depending on how you want the select to work
    $stmt->execute(array(':id' => "1")); // Gives value to :id and executes the statement
    $row = $stmt->fetch();

    // Then run your code

    if (!file_exists(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big')) {
        mkdir(ROOT_PATH.'user/upload/'.$row['UserName'].'/avatar/big', 0777, true);
    }
?>
