    I am on the last step in a tutorial that I followed [here]( “”) , called “Using the data”.

    I tried using//

    < ?php $album_repeatable = unserialize($post_meta_data[0]);
    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?…

    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.

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

    Is that part of the array serialized (I don’t see any reason it would be)?


    in any case, the underlying issue is that you’re passing something to foreach that is not foreach-able. When unserialize() fails, for example, it returns false, which foreach cannot iterate over. It’s also possible that $post_meta_data[0] _was serialized, and unserialize() was successful, but the serialized value didn’t represent an array or iterable object.

    No problem. Basically, I was trying to figure out why you chose to try unserialize in the first place – I thought it was a little unlikely that your data was serialized in the first place …?
