Question

每当新客户创建公司名称时，我都会使用php创建一个文件夹

$sql = "INSERT INTO kd_aboutus (business, category, subcategory, content, uafk, datein) VALUES ('$bn','$cat','$scat','$descr','$userID',now())";
    $run_sql = mysqli_query($conn, $sql);

    if (!file_exists("user/$bn")) {
        mkdir("user/$bn", 0755);
    }

现在，我的问题是，当用户想要编辑他或她的公司名称时，我还需要重命名他们已经创建的文件夹。我应该怎么做。这是我在编辑文件中的代码

$sql = "UPDATE kd_aboutus SET business='$bn', category='$cat', subcategory='$scat', content='$descr' WHERE aboutID='$targetID'";
    $run_sql = mysqli_query($conn, $sql);

Answer 1

您将需要rename函数。请注意，最小参数为string $oldname , string $newname，因此在更改数据库中的记录之前，您需要加载当前名称。

示例

<?php

$query = "SELECT business FROM kd_aboutus WHERE aboutID='$targetID'";

if ($result = $mysqli->query($query)) {
    $row = $result->fetch_assoc();
    if (!empty($row['business'])) {
        $oldBn = $row['business'];
        rename("user/$oldBn", "user/$bn");

        $sql = "UPDATE kd_aboutus SET business='$bn', category='$cat', subcategory='$scat', content='$descr' WHERE aboutID='$targetID'";
        $run_sql = mysqli_query($conn, $sql);
    }
}

以上内容未经测试，但应说明您需要实现的目标。

Answer 2

在重命名之前，您首先必须获取当前文件夹名称。

SELECT business FROM kd_aboutus WHERE aboutID='$targetID';

通过变量获取上述查询的结果。假设$oldbn

然后，rename的文件夹为：

rename("user/$oldbn", "user/$bn");

$sql = "UPDATE kd_aboutus SET business='$bn', category='$cat', subcategory='$scat', content='$descr' WHERE aboutID='$targetID'";
$run_sql = mysqli_query($conn, $sql);

PHP具有重命名文件夹/文件的功能：http://php.net/manual/en/function.rename.php
