PHP表单文件上传不起作用

Question

I want to upload Images or MP4 Videos.

I have this Code:

<form role="form" action="addad.php" method="POST" enctype="multipart/form-data">
  <div class="form-group">
    <label for="file">Image or MP4 Please</label>
    <input type="file" id="FileInput" name="file" required>
    <div id="responses"></div>
  </div>
</form>

if(!isset($_FILES['file'])){ 
   echo "No File";
   exit;
}

$uploaddir = '/var/www/xxxxxx.com/control/uploads/';
$uploadfile = $uploaddir . basename($_FILES['file']['name']);
echo $uploadfile;

if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
   echo "Image succesfully uploaded.";
} else {
   echo "Image uploading failed.";
   exit;
}

But its already crashed in isset with Message "No File", when i try to upload...

Any Ideas? Already checked PHP User and changed folders to www-data Also tried permissions 777 but nothing works.

Everytime it looks like, he dont get any file informations or dont see the file. All other fields in my form works. If i dont make exit; it write all other fields to database.

Answer 1

Make sure your "submit" input/button is inside the form

<form role="form" action="addad.php" method="POST" enctype="multipart/form-data">
  <div class="form-group">
    <label for="file">Image or MP4 Please</label>
    <input type="file" id="FileInput" name="file" required>
    <div id="responses"></div>
  </div>
  <input type="submit" value="Submit File"/>
</form>

In the "addad.php" file, var_dump($_FILES) before the "if(!isset())" part and check if your data is beeing shown, something like this:

Your Condition is Wrong . Use:

if(isset($_FILES['file'])){
