Direct access to values inside of a nested array

[si_douglas]

What am I doing wrong here? Consider this array:

	Array
(
    [post_id] => 2
    [attachment_id] => 48
    [link] => http://conveyorbelts/wp-content/uploads/capsule.jpg
    [source] => http://conveyorbelts/wp-content/uploads/capsule.jpg
    [width] => 150
    [height] => 113
    [image_size] => thumb
    [meta_data] => Array
        (
            [width] => 200
            [height] => 151
            [hwstring_small] => height='96' width='127'
            [file] => capsule.jpg
            [sizes] => Array
                (
                    [thumbnail] => Array
                        (
                            [file] => capsule-150x150.jpg
                            [width] => 150
                            [height] => 150
                        )

            )

        [image_meta] => Array
            (
                [aperture] => 0
                [credit] => 
                [camera] => 
                [caption] => 
                [created_timestamp] => 0
                [copyright] => 
                [focal_length] => 0
                [iso] => 0
                [shutter_speed] => 0
                [title] => 
            )

    )

[mime] => image/jpeg
[filename] => capsule.jpg
[class] => 
)

I would like to access the value "capsule-150x150.jpg". So I write:

(line 61) echo $myarray['meta_data']['sizes']['thumbnail']['file'];

It echos out:

capsule-150x150.jpg<br />
<b>Fatal error</b>:  Cannot use string offset as an array ... on line 61

It is weird that it does output the string but then falls over. Any ideas. How do you reference multiple nested arrays correctly?

What's below that echo line? Can you show us more of the code around that area?

[si_douglas]

This is a WordPress shortcode:
[code=php]
function shortcode_staffblurbs(){
	global $post;
	$i=1;
	$output='';
	while( get_post_meta($post->ID, "staff_name_{$i}", true) != '' ):

	$name = get_post_meta( $post->ID, "staff_name_{$i}", true );
	$text = get_post_meta( $post->ID, "staff_info_{$i}", true );
	$image = get_post_meta( $post->ID, "staff_pic_{$i}", true );

	if( $image ){

		if( function_exists( 'avatar_get_attachment' )){

$image = avatar_get_attachment("attachment_id={$image}&post_id={$post->ID}");
			}

	}
	else {
			$image = '/wp-content/themes/delegate/styles/red/1273114557_emblem-people.png';

	}


	$src =  $image['meta_data']['sizes']['thumbnail']['file'];


	$output .= '<div class="staff">';
	$output .= '<img src=' . $src .' width="72" height="72" class="mugshot" alt="'. $name .'"/>';
	$output .= '<h5>' . $name . '</h5>';
	$output .= '<p>' . $text . '</p>';
	$output .='</div>';	

$i++;
endwhile;


return $output;


}

add_shortcode('staffblurbs','shortcode_staffblurbs');

[/code]

Whoops!
Stuffed the formatting, but that should otherwise make sense. The function avatar_get_attachment retrieves an image with all its meta information in an array (refer to post 1). Still stumped by this.

[si_douglas]

Nuts! I've spotted the error and have fixed it. $image should be renamed to $attachment. Nothing to do with array issue.

PEBKAC!
