global when doing have_posts inside function?

    I need to access some custom field info before doing get_header() in my various templates (e.g., home.php, page.php, archive.php, etc.), so I’ve set up the following in functions.php:

    function F_custom_fields() {
	if (have_posts()) : while (have_posts()) : the_post();
		$custom_fields = get_post_custom();
		$page_icon = $custom_fields['eva_page_icon'][0];
		$div_id = $custom_fields['eva_div_id'][0];
	endwhile; endif;
}

    Since this is not working, I figure there is a variable/array/other that I need to set with global $var as the first thing in the function. I just can’t figure out what it is.

    I ended up having to go about this another (better) way.

    In functions.php:

    function F_custom_fields($need)
{
        // The Loop all on one line
    if (have_posts()) : while (have_posts()) : the_post(); endwhile; endif;
        // Get all of the custom items from the wp_postmeta table for this post/page
    $custom_fields = get_post_custom();
        // Return the needed custom item, if it exists
    if ($need == 'page_icon')
    {
        $page_icon = $custom_fields['eva_page_icon'][0];
        if (!empty($page_icon))
        {
            return $page_icon;
        }
        else
        {
            return FALSE;
        }
    }
    else if ($need == 'div_id')
    {
        $div_id = $custom_fields['eva_div_id'][0];
        if (!empty($div_id))
        {
            return $div_id;
        }
        else
        {
            return FALSE;
        }
    }
}

    In header.php:

    $begin_div_id = F_custom_fields('div_id');
if ($begin_div_id)
{
    echo '<div id="'.$begin_div_id.'">'."\n";
}

    And in footer.php (to close the div tag started in header.php:

    $end_div_id = F_custom_fields('div_id');
if ($end_div_id)
{
    echo '</div>';
}
