Upload script suddenly not working

[BelowZero]

This script has worked for me for years. Suddenly I'm getting the error message when clicking the upload button.
Can anyone help?

The upload page:
<form enctype="multipart/form-data" action="upload.php" method="POST">
<p><b>Click "Choose File" button to upload a file:</b></p>
<div class="spacer"></div>
<input type="file" name="uploaded_file"></input><br />
<div class="spacer"></div>
<input type="submit" value="Upload" class="button"></input>
</form>

<FORM Method = "POST" action ="admin_main.php">
<input type="submit" name="Submit" value="Finished" class="button">
</FORM>

The upload file (upload.php):
<?PHP
if(!empty($_FILES['uploaded_file']))
{
$path = "A-Images/";
$path = $path . basename( $_FILES['uploaded_file']['name']);

if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path))
{header("Location: admin_main.php");}
else
{echo "There was an error uploading the file, please try again!";}
}

echo "The file ". basename( $_FILES['uploaded_file']['name']). " has been uploaded";
?>

I'm thinking it has to do with using a new version of PHP, but can't say for sure. I changed the version back to 7, but it still isn't working.
Any help appreciated!

Hi

try this

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

if(!empty($_FILES['uploaded_file'])) {
    $path = "A-Images/";
    $path = $path . basename($_FILES['uploaded_file']['name']);
    
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path)) {
        header("Location: admin_main.php");
        exit; // Make sure to exit after redirecting
    } else {
        echo "There was an error uploading the file, please try again!";
    }
} else {
    echo "No file was uploaded.";
}
?>

and copy and paste the error received if anyone

Thanks for the reply. I actually fixed the issue by checking the file size before uploading. It seems this particular file was larger than normal and exceeded the size limit. Once I increased the limit, it worked fine. Here is the updated code:

<?PHP
$target_dir = "A-Images/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

if(isset($_POST["submit"])) {
  $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
  if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
  } else {
    echo "File is not an image.";
    $uploadOk = 0;
  }
}

if (file_exists($target_file)) {
  echo "Sorry, file already exists.";
  $uploadOk = 0;
}

if ($_FILES["fileToUpload"]["size"] > 10000000) {
  echo "Sorry, your file is too large.";
  $uploadOk = 0;
}

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
  echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
  $uploadOk = 0;
}

if ($uploadOk == 0) {
  echo "Sorry, your file was not uploaded.";

} else {
  if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
    header("Location: admin_main.php");
  } else {
    echo "Sorry, there was an error uploading your file.";
  }
}

?>
