Turn working code into a Shortcode

Hello,

I have been trying to convert this working php code into a WordPress Shortcode. Could someone help me out?

<form action=”#” method=”get”>
<select name=”page_id” id=”page_id” onchange=”document.location = this.value”>
<option value=”test”>Select Document</option>
<?php

$q1_args = array(
‘tag’ => ‘hoki-3’
);
$q1_posts = get_posts( $q1_args );

$q2_args = array(
‘media-tags’ => ‘hoki-4’
);
$q2_posts= get_posts( $q2_args );

$final_posts = array_merge( $q1_posts, $q2_posts );

foreach ( $final_posts as $key => $post ) {

setup_postdata( $post );

echo ‘<option value=”‘. get_the_permalink() . ‘”>’. get_the_title() .'</option>’;

}
?>
</select>
<noscript>
<input type=”submit” value=”View” />
</noscript>
</form>

Thanks,

Tim
