Getting “Invalid argument supplied for foreach()” Warning…

[asiek]

I am on the last step in a tutorial that I followed [here](http://wp.tutsplus.com/tutorials/reusable-custom-meta-boxes-part-4-using-the-data/ “http://wp.tutsplus.com/tutorials/reusable-custom-meta-boxes-part-4-using-the-data/”) , called “Using the data”.

I tried using//

echo '[ul class="album_repeatable"]';

foreach ($album_repeatable as $string) {

echo '[li]'.$string.'[/li]';

}

echo '[/ul]';

?>

But I get the Warning as stated in Discussion Title//

“_Warning: Invalid argument supplied for foreach()_ “

What exactly is the issue here, in terms I could understand? lol
Please help me fix this?…

**SOLUTION**//
Used normal method to get field data instead of “_unserialize_”

Switched this line:

$album_repeatable = unserialize($post_meta_data[0]);

to this line:

$album_repeatable = get_post_meta($post->ID, 'album_repeatable', true);

Now my repeatable field Data is being displayed.
