       if (move_uploaded_file($_FILES["userimage"]["tmp_name"], $target_file)) {

           $values = [
             'user_image' => '/eduflow/code/uploads/' . imagecrop($image, ['x' => 0, 'y' => 0, 'width' => 54, 'height' => 54]  ),

           $user->updateUserPhoto($_SESSION['user_id'], $values);
       } else {
           echo "Sorry, er was een fout bij het uploaden van uw foto.";
       }
   }
}

The file php7AD6.tmp has been uploaded.文件 php7AD6.tmp 已上传。

I get this errors我得到这个错误

Warning: imagecreatefrompng(C:\xampp\tmp\php7AD6.tmp): failed to open stream: No such file or directory in C:\xampp\htdocs\eduflow\code\admin\photo_import.php on line 51 Warning: imagecreatefrompng(C:\xampp\tmp\php7AD6.tmp): failed to open stream: No such file or directory in C:\xampp\htdocs\eduflow\code\admin\photo_import.php on line 51

Warning: imagecrop() expects parameter 1 to be resource, bool given in C:\xampp\htdocs\eduflow\code\admin\photo_import.php on line 53警告：imagecrop() 期望参数 1 是资源，布尔值在 C:\xampp\htdocs\eduflow\code\admin\photo_import.php 第 53 行中给出

The photo does upload but after that nothing happens.照片确实上传了，但之后没有任何反应。 What I would like to happen is upload it to the directory and database, after that I return it on another page.我想要发生的是将它上传到目录和数据库，然后我在另一个页面上返回它。

Because you are calling not existing file因为您正在调用不存在的文件

$image = imagecreatefrompng($_FILES['userimage']['tmp_name']);

change to改成

$image = imagecreatefrompng($target_file);
