What are some best practices for creating a delete button for an upload script in PHP?

When creating a delete button for an upload script in PHP, it is important to ensure that the user has the necessary permissions to delete the file and that the file is actually deleted from the server upon clicking the button. One best practice is to use a secure method such as POST to send the file path to a delete script, which then verifies the user's permissions before deleting the file. 

<?php
// Check if the delete button was clicked
if(isset($_POST['delete'])){
    $file_path = $_POST['file_path'];
    
    // Verify user permissions to delete the file
    // Add your permission verification code here
    
    // Delete the file from the server
    if(unlink($file_path)){
        echo "File deleted successfully.";
    } else {
        echo "Error deleting file.";
    }
}
?>

<form method="post" action="">
    <input type="hidden" name="file_path" value="path/to/file">
    <button type="submit" name="delete">Delete File</button>
</form>
