How can i retrieve a picture, let say ( No picture ) when i don't add a picture in my custom field

I use this code to retrive the field...

<img class="film" 
     src="/scripts/timthumb.php?src=<?php the_field('img_actor'); ?>&h=251&w=175&zc=1"
     alt="<?php the_title(); ?>"  
     title="<?php the_title(); ?>"/>

How to retrive no-picture from this code

if(get_field('distributie') != ""){$counter=0;foreach(get_field('distributie') as $post_object): ?>
    <div class="act-box">
<a href="<?php echo get_permalink($post_object->ID); ?>" title="Actor <?php echo get_the_title($post_object->ID) ?>">
<img class="actor_img" src="/scripts/timthumb.php?src=<?php echo get_field( 'img_actor', $post_object->ID ); ?>&h=70&w=50&zc=1" alt="<?php echo get_the_title($post_object->ID) ?>" title="<?php echo get_the_title($post_object->ID) ?>" /></a>
        <span class="act-titlu">
<a href="<?php echo get_permalink($post_object->ID); ?>" title="Actor <?php echo get_the_title($post_object->ID) ?>"><?php echo get_the_title($post_object->ID) ?></a>
<?php $counter++;if($counter>=8) break; endforeach;}?>

If i change

<?php echo get_field( 'img_actor', $post_object->ID ); ?>


<?php echo urlencode($img); ?>

I get an error ($post_object->ID) where do i put it?

the_field is not a WordPress function, but I'll assume you can check if it's empty or not using a conditional. – Wyck Jan 2 '13 at 20:02
i know how to retrive a picture, the question si how to get a default picture, if no picture is added.. – Lucica Jan 2 '13 at 20:07
And where does this default picture come from? – Wyck Jan 2 '13 at 20:08

Test the value before you use it:

if ( ! $img = get_field('img_actor', get_the_ID() ) )
    $img = 'http://www.example.com/wp-content/uploads/default.jpg';
<img class="film" 
     src="/scripts/timthumb.php?src=<?php echo urlencode($img); ?>&h=251&w=175&zc=1"
     alt="<?php the_title_attribute(); ?>"  
     title="<?php the_title_attribute(); ?>"/>

I recommend not to use the same text for title and alt, this is very annoying for screen reader users.

Toscho, please look at the first post... – Lucica Jan 2 '13 at 20:42
@LucicaCopil Use get_the_ID() to get the post ID. – toscho Jan 2 '13 at 20:45

$img = get_field('img_actor', $post_object->ID - solve the problem... thanks again – Lucica Jan 2 '13 at 20:55

Here is what I use for image redundancy.

1.First it tries to get the featured image
2.Then the first image attached to the post
3.Then a default image.

 $attachments = get_children(
                                   'numberposts' => 1,
                                   'order'=> 'ASC',
                                   'post_mime_type' => 'image',
                                   'post_parent' => get_the_ID(),
                                   'post_status' => null,
                                   'post_type' => 'attachment'

        //first check for featured image
        if ( has_post_thumbnail() ) {


        //no featured image get first attachment   
        } elseif ($attachments) { 

        $first_attachment = reset($attachments);
            echo wp_get_attachment_image($first_attachment->ID, 'thumbnail');

        } else {
            echo '<img src="../something/default.jpg"'; 

ps. You can insert the crap timthumb into it if you want or a 4th check for your custom get_field('img_actor')
