Missing an image in my custon code (4 posts)

    I've written my very first function - and shortcode - more or less from scratch, and it almost works perfectly (for what I want, I mean):

    codefunction get_the_person($atts, $content=null) {
    'pid' => 0, 'align' => 'left'
    ), $atts));
    /* global $post; */
    $address = get_bloginfo("template_url");
    $person_id = get_post($pid);
    $ret='<div id="person-'.$person_id->ID.'" class="person">';
    $ret.='<p> post_name.'" rel="bookmark" title="'.$person_id ->post_title.'">';
    if(has_post_thumbnail()) {
    $pid_image = get_the_post_thumbnail( $person_id->ID, 'thumbnail', array( 'class' => 'index-post-thm border person-align-'.$align.'', alt => 'Alt text' ) );
    } else { $pid_image='<img src="'.$address.'/images/img-default.jpg" class="index-post-thm border" alt="blank" />' ; }
    $ret.= $pid_image; $ret.= $person_id -> post_title.'
    <!-- br / -->'.$person_id -> post_excerpt.'</p></div>';
    return $ret;

    Sorry about the ugliness of the code. I'm new to it.

    Anyway, there are two problems which have got me stumped. Firstly, even though I've removed wpautop, that $person_id -> post_excerpt bit is still wrapped in unwanted p tags. Grr.

    Secondly; if there is no thumbnail associated with the called post, then the img tag is ignored, even though I set the variable to something to cope with such events. It's not that there's an image error in the browser; the image tag is completely left out.

    What am I doing wrong?

    Also, sorry for the way that formatted - I don't usually post code, anywhere.

    Okay... further investigation shows that the functions works fine - it just won't work if you include the shortcode more than once in the same page.

    If postA has no thumbnail but postB does, then two blanks are produced.

    If PostA has a thumbnail but postB doesn't, then a thumbnail is produced for postA and no tag/result at all for postB.

    The value of has_post_thumbnail() is persisting across iterations of the shortcode, so is there something that resets all the values, or something like %posts -> post_thumbnail ?

    Ha! Fixed!

    Used get_the_post_thumbnail($pid) instead.
