[RESOLVED] Please Help! Invalid Argument issue

[BlackedOut271]

I'm attemping to correct an issue with our WordPress template. Here is the error it's spitting out at me... Line 334 is red in the code below. That's where I believe my issue is. I'm fairly new at the coding side, I've been a designer for quite some time however, so please be easy on me lol. Thanks in advance!

Using WordPress 3.3.1 / Theme up-to-date as well / "Warp" framework by YooTheme

Actually link to site is kinda pointless, sorry... going to work with a different template just incase I get no replies. It would be great if anyone could help me out here though, the template I'm having the issue with is the one we want to run with!

For whatever help it might be, the error is telling you that $ids is not an array, which is what foreach() expects it to be. As to why it's not an array -- or if it even should be -- is unknowable with the current info.

[ScottyBoy]

The easy fix here is to check to see if $ids is a an array before foreaching it. That should suppress this particular error, although this could be a "band-aid" fix, as may be part of a larger problem.

    foreach (wp_get_sidebars_widgets() as $pos => $ids)

        if (!empty($ids) && is_array($ids))
        {

Thanks guys. Got it running. Amazing what you can do when you learn PHP. Took about two days to get a decent understanding. I've been missing out.

So exactly what was the fix for the invalid argument error on line 334? Having same issue here. Thanks!

Hi Guys i was also wondering how you fixed this problem. I have the same error for a yootheme.

Warning: Invalid argument supplied for foreach() in /home2/aussieba/public_html/dzonepattaya/wp-content/themes/yoo_shelf_wp/warp/systems/wordpress.3.0/helpers/widgets.php on line 107

I dont really understand why im getting this error. I used the same template on another website and it was fine. Ive checked the code on the other website using this theme and it looks exactly the same as it does when im trying to use it for the new website.

The only difference is the new website is using a newer instillation of wordpress but i dont think it should make any difference.

Anyhow, be good to here some suggestions, i see @gfogleman has been waiting for a while for his response to the same question so ill look for alternatives in the mean time.

Im not a programmer but can follow clear instructions.

Thanks for the time

Ben
