mam tento kod a ako by som zobrazil po nevybrani ziadneho suborum na upload napr. "prosim vyber subor!"
<form method="post" enctype="multipart/form-data" action="index.php">
<input type="hidden" name="upload" value="true" />
<input type="file" name="filename"><br>
<p><input type="submit" value="check"></p>
</form>
