我有一个将视频上传到服务器的脚本，一切正常，但在视频上传到服务器完成后出现问题 它以数组形式显示（uploads）文件夹中所有上传的文件！
我只想要我刚刚上传的文件的结果，它不显示以前的文件！ 我需要 ffmpeg 来提高视频质量

上传.php
<?php
//upload.php
$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';
if(!empty($_FILES))
{
$temp_file = $_FILES['file']['tmp_name'];
$location = $folder_name . $_FILES['file']['name'];
move_uploaded_file($temp_file, $location);
$upload = $_FILES['file']['name'];
$uploadStr = str_replace(" ", "\ ",$upload);
$locationStr = str_replace(" ","\ ",$location);
$cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
echo shell_exec($cmd);
}
if(isset($_POST["name"]))
{
$filename = $folder_name.$_POST["name"];
$imagename = $thumb_name.$_POST["name"].$imageext;
unlink($filename);
unlink($imagename);
}
$result = array();
$files = scandir('upload');
$output = '<div class="row">';
if(false !== $files)
{
foreach($files as $file)
{
if('.' != $file && '..' != $file)
{
$output .= '
<a href="/view.php?file='.$file.'" target="_blank"> <img src="thumb/'.$file.'.png" class="img-thumbnail" width="246px" height="138px" style="height:138px;" /></a>
<button type="button" class="btn btn-link remove_image" id="'.$file.'">Remove</button>
';
}
}
}
$output .= '</div>';
echo $output;
?>
EDIT:我将示例放在一个数组中，我不需要它，我只想它显示我刚刚上传的下载视频。
EDIT 2 :有些人说输入 $location 它会显示下载的文件，但这不起作用！ 我只是尝试了不止一次并且多次使用，没有显示文本为空的地方
这是一个例子
<?php
//upload.php
$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';
if(!empty($_FILES))
{
$temp_file = $_FILES['file']['tmp_name'];
$location = $folder_name . $_FILES['file']['name'];
move_uploaded_file($temp_file, $location);
$upload = $_FILES['file']['name'];
$uploadStr = str_replace(" ", "\ ",$upload);
$locationStr = str_replace(" ","\ ",$location);
$cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
echo shell_exec($cmd);
}
if(isset($_POST["name"]))
{
$filename = $folder_name.$_POST["name"];
$imagename = $thumb_name.$_POST["name"].$imageext;
unlink($filename);
unlink($imagename);
}
$output .= 'Successfly file is "'.$location.'"';
echo $output;
?>
Result: 成功飞行的文件是“” 没有名称文件:(
EDIT 3 :
这段代码upload.php 功能不工作
<?php
//upload.php
$folder_name = 'upload/';
$tumb_name = 'thumb/';
$imageext = '.png';
if(!empty($_FILES))
{
$temp_file = $_FILES['file']['tmp_name'];
$location = $folder_name . $_FILES['file']['name'];
move_uploaded_file($temp_file, $location);
$upload = $_FILES['file']['name'];
$uploadStr = str_replace(" ", "\ ",$upload);
$locationStr = str_replace(" ","\ ",$location);
$cmd = "ffmpeg -y -i {$locationStr} -ss 00:00:15 -vframes 1 thumb/{$uploadStr}.png 2>&1";
echo shell_exec($cmd);
}
echo "The file " . $location . " has been uploaded";
// not working
echo "<br>";
echo "The file " . $upload . " has been uploaded";
// not working
echo "<br>";
echo "The file " . $uploadStr . " has been uploaded";
// not working
echo "<br>";
echo "The file " . $locationStr . " has been uploaded";
// not working
?>
这个错误： [2022 年 4 月 23 日 12:31:56 亚洲/利雅得] PHP 注意：未定义变量：位于 /home/prdix/public_html/test/upload.php 第 38 行
第 38 行: echo $location;
关于开发者解决方案 Markus AO
I did the experiment and it is quite good, but dropzone is still missing, because I will upload a large video and the normal upload compresses the video before uploading, here is a picture from my mobile while uploading, but this does not happen with dropzone
我也想在 dropzone 中实现这一点，因为这个库不会压缩视频，而是以全尺寸上传。
谢啦兄弟。
