PHP 根据HTML 复选框上传到特定文件夹

PHP upload to certain folder based on HTML checkbox

我是 PHP 的新手,仍在学习中,但我想知道我是否能够做这样的事情。我有一个基本的 HTML 表格,如下所示。

<form action="upload.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
<label><input type="checkbox" id="cb" value="checkb">Make Private.</label>
</form>

还有像下面这样的基本上传 PHP 文档。

<?php

if ($_FILES["file"]["size"] < 2097152) {
    if ($_FILES["file"]["error"] > 0) {
        header('Location: /');
    }else {
        echo "Original Name: " . $_FILES["file"]["name"] . "<br>";
        echo "File Type: " . $_FILES["file"]["type"] . "<br>";
        echo "File Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
        $randprefix = hash('ripemd160', openssl_random_pseudo_bytes(32), false);
        $filepath = "upload/" . $randprefix . $_FILES["file"]["name"];
        if (file_exists($filepath)) {
            echo $filepath . " already exists. ";
        }else {
            move_uploaded_file($_FILES["file"]["tmp_name"], $filepath);
            echo "Link to file: " . '<a href = "' . $filepath . '">' . $filepath . '</a>' ;

        }
    }
}else {
    echo "File too large.";
}
?>

我想问的是,是否可以在 HTML 表单上添加一个复选框,选中后文件将上传到名为 "private" 的文件夹,取消选中时文件将上传到名为 "public" 的文件夹。谢谢。

您可以使用这样的条件,以便在提交表单后只有您可以获得复选框的值。

if(isset($_POST['check']))
{
    $filepath = "upload/private" . $randprefix . $_FILES["file"]["name"];
}
else
{
    $filepath = "upload/public" . $randprefix . $_FILES["file"]["name"];
}

You have to place the name for the checkbox input type so that you can check in the upload.php page and then set the folder over there.

替换:

<label><input type="checkbox" id="cb" value="checkb">Make Private.</label>

有:

<label><input type="checkbox" id="cb" value="checkb" name="check">Make Private.</label>

说明:当用户在提交时选中复选框时,将检查复选框值,并使$filepathupload/private 或者如果用户在提交数据时 he/she 没有选中复选框,它将根据复选框值的选择更改代码。这样您就可以move_upload_file()根据可用的选择。

<form action="upload.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
<label><input type="checkbox" id="cb" name="checkb" value="checkb">Make Private.</label>
</form>
<?php
if ($_FILES["file"]["size"] < 2097152)
{
  if ($_FILES["file"]["error"] > 0)
  {
    header('Location: /');
  }
  else
  {
    echo "Original Name: " . $_FILES["file"]["name"] . "<br>";
    echo "File Type: " . $_FILES["file"]["type"] . "<br>";
    echo "File Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    $randprefix = hash('ripemd160', openssl_random_pseudo_bytes(32), false);
    if($_POST['checkb'] == "checkb")
    {
      $filepath = "private/" . $randprefix . $_FILES["file"]["name"];
    }
    else
    {
      $filepath = "upload/" . $randprefix . $_FILES["file"]["name"];
    }
    if (file_exists($filepath))
    {
      echo $filepath . " already exists. ";
    }
else
{
  move_uploaded_file($_FILES["file"]["tmp_name"], $filepath);
  echo "Link to file: " . '<a href = "' . $filepath . '">' . $filepath . '</a>' ;

    }
  }
}
else
{
  echo "File too large.";
}
?>

我认为这是我测试过的作品,你没有问题可以复制!
