<input type="file" name="attachment"> warning Undefined index: attachment

<form action="1st_page.php"  method="post" >
<input type="file" name="attachment" id="attachment" >
<input class="button" type="submit" name="submit" value="Submit" />
</form>

below is 1st_page.php

<?php
$_SESSION['attachment'] = trim ($_POST['attachment']);
?>

At 1st the input type =file i would like to allow user to attach file or picture whenever they like. But when user did not upload the file which mean the $_POST['attachment'] doest not have any data/string therefore i have warning on 1st-page.php Undefined index: attachment.

How can i get rid of this warning?

do it like this <?php if(isset($_POST['attachment'])) { $_SESSION['attachment'] = trim ($_POST['attachment']); } ?>

Try the above and see if it works.
