大家好我用视频大小和类型验证创建了我的上传文件.仅允许webm,mp4和ogv文件类型,最大文件大小为2GB.我的PHP代码:
if (isset($_POST['submit']))
{
$file_name = $_FILES['file']['name'];
$file_type = $_FILES['file']['type'];
$file_size = $_FILES['file']['size'];
$allowed_extensions = array("webm", "mp4", "ogv");
$file_name_temp = explode(".", $file_name);
$extension = end($file_name_temp);
$file_size_max = 2147483648;
if (!empty($file_name))
{
if (($file_type == "video/webm") || ($file_type == "video/mp4") || ($file_type == "video/ogv") &&
($file_size < $file_size_max) && in_array($extension, $allowed_extensions))
{
if ($_FILES['file']['error'] > 0)
{
echo "Unexpected error occured, please try again later.";
} else {
if (file_exists("secure/".$file_name))
{
echo $file_name." already exists.";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"], "secure/".$file_name);
echo …我定制了我的输入类型="文件",就像Facebook上传而不是文本框和一个按钮(默认输入类型="文件")我只输入一个按钮,没有文本框,你可以看到文件的路径.我打算在我的自定义输入文件旁边添加一个span或ap标签来显示文件的路径.
选择文件时,如何将文件路径打印到span标记？
HTML代码
<!doctype>
<html>
<head>
</head>
<body>
<div class="browse-wrap">
<div class="title">Choose a file to upload</div>
<input type="file" name="upload" class="upload" title="Choose a file to upload">
</div>
<span class="upload-path"></span>
</body>
</html>
css代码
div.browse-wrap {
top:0;
left:0;
margin:20px;
cursor:pointer;
overflow:hidden;
padding:20px 60px;
text-align:center;
position:relative;
background-color:#f6f7f8;
border:solid 1px #d2d2d7;}
div.title {
color:#3b5998;
font-size:14px;
font-weight:bold;
font-family:tahoma, arial, sans-serif;}
input.upload {
right:0;
margin:0;
bottom:0;
padding:0;
opacity:0;
height:300px;
outline:none;
cursor:inherit;
position:absolute;
font-size:1000px !important;}
span.upload-path {
margin:20px;
display:block;}
谢谢!
