我正在制作一个上传系统，用户可以在其中上传图像和视频，但是我在上传系统上遇到问题。主要在上传视频上。图片很好，可以上传，但是当我尝试上传视频时问题就开始了。尝试上传视频时没有显示任何错误，所以我什至不知道问题出在哪里。当前这是我的PHP代码：
<?php
if(isset($_POST['btn-add']))
{
$name=$_POST['user_name'];
$images=$_FILES['profile']['name'];
$path = "uploads/";
$rand=rand(1000, 1000000);
$filename = "$rand.jpg";
$filepath = "$path$filename";
function correctImageOrientation($filename) {
if (function_exists('exif_read_data')) {
$exif = exif_read_data($filename);
if($exif && isset($exif['Orientation'])) {
$orientation = $exif['Orientation'];
if($orientation != 1){
$img = imagecreatefromjpeg($filename);
$deg = 0;
switch ($orientation) {
case 3:
$deg = 180;
break;
case 6:
$deg = 270;
break;
case 8:
$deg = 90;
break;
}
if ($deg) {
$img = imagerotate($img, $deg, 0);
}
// then rewrite the rotated image back to the disk as $filename
imagejpeg($img, $filename, 95);
} // if there is some rotation necessary
} // if have the exif orientation info
} // if function exists
}
$imgExt=strtolower(pathinfo($images,PATHINFO_EXTENSION));
move_uploaded_file($_FILES["profile"]["tmp_name"], $filepath);
if($imgExt == "jpg" || $imgExt == "jpeg" || $imgExt == "png" || $imgExt == "gif"){
correctImageOrientation($filepath);
if ($imgExt == "jpeg" || $imgExt == "jpg") {
$im = imagecreatefromjpeg($filepath);
}else if($imgExt == "png"){
$im = imagecreatefrompng($filepath);
}else if($imgExt == "gif"){
$im = imagecreatefromgif($filepath);
}
$size = getimagesize($filepath);
$width = imagesx($im);
$height = imagesy($im);
$newwidth= 300;
$newheight= 300;
if(($width/$newwidth) < ($height/$newheight)){
$y = 0;
$x = $width - (($height * $newwidth) / $newheight);
}else{
$x = 0;
$y = $height - (($width * $newheight) / $newwidth);
}
$virtual_image = imagecreatetruecolor(301, 301);
imagealphablending($virtual_image, true);
imagesavealpha($virtual_image, true);
imagecopyresampled($virtual_image,$im,0,0, $x/2, $y/2, $newwidth, $newheight, $width-$x, $height-$y);
$bgcolor = imagecolorallocatealpha($virtual_image,255,255,255,127);
imagefill($virtual_image,0,0,$bgcolor);
imagecolortransparent($virtual_image, $bgcolor);
imagejpeg($virtual_image,$filepath,100);
}else if ($imgExt == "mp4"){
}else echo "Invalid file";
$stmt=$db_conn->prepare('INSERT INTO tbl_user(username, picprofile) VALUES (:uname, :upic)');
$stmt->bindParam(':uname', $name);
$stmt->bindParam(':upic', $filename);
if($stmt->execute())
{
?>
<script>
</script>
<?php
}else
{
?>
<script>
</script>
<?php
}
}
?>
我无法发表评论，对不起，所以我只作为答复发布，但您没有指定如果文件扩展名是Mp4时应执行的代码
}else if ($imgExt == "mp4"){
//here should contain your codes and commands if the file is mp4
}
因此php不处理文件，也没有错误，请检查特定的上传文件夹和temp文件夹
