我想上传文件，格式为skuTF.getText() :)但是当我点击上传按钮时，他正在上传每种类型的文件类型:)并保存为文件格式，如“.file”并调用mp4,webm,ogg ..如何只上传mp4，web或ogg格式.. :)以下是我的代码：
"Sucessfully uploaded" ..没有任何sytax问题，只有错误是<main>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="file"></input>
<input type="submit" value="Upload"></input>
</form>
<?php
$maxsize = 800000000;
$fileformat = substr(@$_FILES["file"]["name"],4,-4);
$filename = rand(0,99999999).$fileformat;
$filepath = "uploaded/".$filename;
if (@$_FILES["file"]["size"]>$maxsize) {
echo "maximum upload size is 800MB";
} else {
$d = @$_FILES["file"]["type"];
if ($d=="video/mp4" || $d=="video/webm" || $d="video/ogg"){
if (is_uploaded_file(@$_FILES["file"]["tmp_name"])) {
$move = move_uploaded_file($_FILES["file"]["tmp_name"],$filepath);
if ($move) {echo "succesfully uploaded";}
else {echo "upload error";}
}
} else {echo "Supported video formats are mp4, webm and ogg";}
}
?>
</main>
这应该是正常的错误因为我没有选择文件......
