Question

基本上我想用html表单上传图片和视频文件。图像上传但视频文件没有，当我上传视频文件时显示进度....看不到任何东西..我的代码有什么问题，有人可以帮帮我吗？

<?php
if(isset($_POST['submit']) == "Submit")
{   
$err = array(); 
@$filed = addslashes($_FILES['file']['tmp_name']);
@$img_named =    addslashes($_FILES['file']['name']);
@$img_sized = getimagesize($_FILES['file']['tmp_name']);
@$imgd = addslashes(file_get_contents($_FILES['file']['tmp_name']));

function getExtension($str)
    {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
    }
$extension = getExtension($img_named);
$extension = strtolower($extension);
$image_named_uniq = uniqid().'.'.$extension;

$upload_path_dis = 'user/manage/discussionimg/';

$diss = $_POST['type'];
$sub = $_POST['sub'];
$msg = $_POST['msg'];
$date = "On " . date("F Y h:i:s A");


if (!isset($_SESSION['uname']))
$err[] = "You need to login";

else
{
$uname = $_SESSION['uname']; //session username

if(empty($sub) && empty($msg) && empty($filed))
$err[] = "All field required";
else
{
if(empty($sub))
$err[] = "Subject Requried";

if(empty($msg))
$err[] = "Message Requried";

if(empty($filed))
$err[] ="SORRY, you have to be upload a image";
else
{ 
if($img_sized == FALSE)
{
$err[] ="That's not an image";  
}
}
}
}


if(!empty($err))
{
foreach($err as $er)
{
echo "<font color=red>$er</font><br/>";
}
}

else
{
$sql= mysql_query("INSERT INTO discussion VALUES ('', '$imgd', '$image_named_uniq', '$diss', '$sub', '$msg', '$uname', '$date' ) ");
if(!$sql)
echo "Can't submit your discussion" . mysql_error();
if(!move_uploaded_file($_FILES['file']['tmp_name'],$upload_path_dis . $image_named_uniq))
{
die('File Not Uploading');
}
else
{
echo "Discussion was submitted";
print "<script>";
print " self.location='          "  .$_SERVER['REQUEST_URI'] . "        ';"; // Comment this line if you don't want to redirect
print "</script>";

}       
}       

}

Answer 1

删除@错误抑制因素，您将看到问题所在：

$filed = addslashes($_FILES['file']['tmp_name']);
$img_named =    addslashes($_FILES['file']['name']);
$img_sized = getimagesize($_FILES['file']['tmp_name']);
$imgd = addslashes(file_get_contents($_FILES['file']['tmp_name']));

这行代码获取图像的大小：

$img_sized = getimagesize($_FILES['file']['tmp_name']);

当图像是视频文件时会发生什么？你得到一个错误。

要修复此问题，请使用MIME类型或扩展名检查文件是图像还是视频文件（不推荐）。如果是图像，请获取尺寸。如果不是，请不要大小。

Answer 2

如果您打算使用上传文件大小保护，请不要使用@ $ img_sized = getimagesize（$ _ FILES ['file'] ['tmp_name']）;而不是使用这个

@$img_sized = $_FILES['file']['size'];

这将获取所有文件扩展名的文件大小，并删除行@ $ img_sized = getimagesize（$ _ FILES ['file'] ['tmp_name']）;这会给图像和视频等提供不可读或警告。

Answer 3

你必须在php.ini文件中设置一些设置，如果你不这样做，那么设置.htaccess文件来增加大小
