Php文件上传处理不会工作/文件没有出现 [英] Php file upload handling wont work/file doesnt appear

问题描述

我有一个表单来上传文件：

I have a form to upload a file:

<form enctype="multipart/form-data" method="post" action="pphoto.php">
Upload Photo: <input name="photo" type="file" required> By: <input name="by" type="text" required>
</form>

这些是表单的动作：

These is the action of the form:

<?php

if($_FILES['photo']['name'])
{
	//if no errors...
	if(!$_FILES['photo']['error'])
	{
		//now is the time to modify the future file name and validate the file
		$new_file_name = strtolower($_FILES['photo']['name']); //rename file
		if($_FILES['photo']['size'] > (1024000)) //can't be larger than 1 MB
		{
			$valid_file = false;
			$message = 'Oops!  Your file\'s size is to large.';
		}else { $valid_file = true; }
		
		//if the file has passed the test
		if($valid_file)
		{
			//move it to where we want it to be
			move_uploaded_file($_FILES['photo']['name'], './images/'.$new_file_name);
			$message = 'Congratulations!  Your file was accepted.';
		}
	}
	//if there is an error...
	else
	{
		//set that to be the returned message
		$message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['photo']['error'];
	}
}
echo $message;

$myFile = "photos.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "<img src=\"../photos/". $_FILES['photo']['name'] ." \">";
fwrite($fh, $stringData);
fclose($fh);

?>

上传的内容比检查文件大小和对于错误，如果一切都好，则将其移动到images目录。当我上传图像时，图像目录中没有任何内容。



为什么会发生这种情况？

What happens is it uploads than checks file size and for errors, if all is good it moves it to the images directory. When i upload an image nothing appears in the image directory.

Why is this happenning?

推荐答案

_FILES [' photo'] [' name']）
{
// 如果没有错误......
if（！

_FILES['photo']['name']) { //if no errors... if(!

_FILES [' photo'] [' error']）
{
// 现在是修改未来文件名和验证文件的时间

_FILES['photo']['error']) { //now is the time to modify the future file name and validate the file

new_file_name = strtolower（

new_file_name = strtolower(
