我无法使用php将文件上传到运行httpd的CentOS 7服务器。
我已经搜遍过，但仍然无法弄清楚为什么我无法上传文件。 ：（
以下是表格：
<div class="container">
<div class="row">
<div class="col-lg-4 col-lg-offset-4">
<h2 class="section-heading text-white text-center">Private Upload Page</h2>
<hr class="light">
<form class="form-horizontal" role="form" action="upload.php" method="post" enctype="multipart/form-data">
<div class="form-group">
<span class="text-white">Select directory to upload to:</span><br>
<input class="form-control" type="text" name="dir" value="/var/www/html/Private/uploads" style="width: 100%;"><br>
<span class="text-white">Select file to upload:</span><br>
<input class="form-control" type="file" name="fileToUpload" id="fileToUpload" style="width: 100%;"><br>
<input class="form-control btn btn-primary" type="submit" value="Upload File" name="submit" >
</form>
</div>
</div>
</div>
这是php文件：
<?php
// Check directory from form, otherwise use uploads folder in
// /var/www/html/Private
if(isset($_POST["dir"])) {
$target_dir = $_POST["dir"];
echo "<p>Using " . $target_dir . " for directory.</p><br>";
}
else {
$target_dir = "/var/www/html/Private/uploads/";
echo "<p>Using /var/www/html/Private/uploads for directory.</p><br>";
}
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
我尝试过设置：
chmod 777 /var/www/html
和
chmod 777 /var/www
以及在php.ini文件中打开文件写入
以及关闭防火墙，我仍然无法上传文件。
我对网页设计很新，所以我确定这是我造成的问题。我查看的每个页面都指向了权限，但即使允许777仍然无法解决我的问题。
答案 0 :(得分：0)
您的代码看起来不错。您是否在file_uploads = On上启用了php.ini？如果不搜索file_uploads directive并将其设置为开启。
答案 1 :(得分：0)
您应该将根目录（即指定目录存在/将要创建的目录）添加到输入的目录名称中。
还要确保使用客户端或服务器端验证有一个尾部斜杠，因为用户可能忘记输入它。
