A: How do I fix this error: Warning: invalid argument supplied for foreach()?

This usually happens when you are trying to do admin navigation stuff and you aren't hooked into admin_menu. If you hook in before that, $menu hasn't been created yet. add_action('admin_menu', 'my_plugin_add_menu'); function my_plugin_add_menu(){ $ptype = 'my_post_type'; $ptype_obj = ge...

I tried removing all the admin nav stuff and the issue still remained. Here is a paste of the relevant functions.php code - do you see anything there? pastebin.com/2f1AaxPU

Chacha102

Are you using admin_init or admin_menu? There is a difference...

timshutes

add_action( 'init', 'register_my_menus' );

Chacha102

I'm talking about for when you call 'remove_menu_page'

timshutes

added the remove_menu_page code above

Chacha102

So, now you should go back and read my answer again, and see how it applies to the code you just gave me.

timshutes

Ok - I edited the code and moved the add_action(...) above the function. I am still getting the error, however. Am I understanding you correctly?

Chacha102

No. you are using admin_init. When admin_init happens, the menus haven't been loaded. It isn't until admin_menu happens that $menu is loaded.

Hey

Anyone alive?

timshutes

yeah

sorry it took me a while to get logged in - first time using the chat feature

Chacha102

Hey

timshutes

ok sorry I'm new at some of this.. you might have to spell if out for me a little more.. I appreciate your help

No problem

So, hooks are like events in Wordpress

they happen in an order

timshutes

got it

Chacha102

So, in this case, the code you posted was hooking into 'admin_init', which happens at the very beginning of an admin page load

timshutes

you think my error is b/c mine are out of order somehow

Chacha102

However, Wordpress's Codex tells us that we should use 'admin_menu', because that is when the menu is being renderred

Otherwise you'll try to remove an item that isn't even there yet

timshutes

ok got it, so I'll go through and anytime I'm editing the admin menu I should use 'admin_menu' rather than 'admin_init'

Chacha102

23:32

Right

I ran into that problem a couple times with menus

timshutes

ok I think I have that fixed, but I'm still getting the error

Chacha102

Really?

Same error?

timshutes

it's interesting because I wasn't getting the error (and still am not) on my local build which has the same functions.php as the upload

yeah - it happens only on certain events

like in the appearance > widgets - adding a widget to a sidebar triggers the error in the sidebar

on settings > general -- changing the date structure and clicking away triggers the event

Chacha102

And it is when you reload right?

That sounds AJAXy..

timshutes

nope - it's when I do something else - like update a meta box

or drag a widget into a sidebar

yeah - it feels ajaxy to me - it seems to trigger on ajax events

I feel like something got goofed up with my menus when I installed the clean version of wordpress and used the importer to bring in the info

but I don't have the first clue how to narrow it down

Chacha102

23:37

The first thing I'd do is find a cause. Comment out each add_action one at a time and test if the error still happens

When you find the offending function, then you can look at the hook it is hooked into, the parameters it is giving, etc

timshutes

ok - believe it or not, I took my functions.php file down to the barebones twentyten functions and I'm still getting the error

Chacha102

Thats a problem :)

If possible, you might want to reinstall

Or try a different theme

timshutes

yeah I'm going to reinstall and try again b/c something obviously got screwed up

with custom menus, when should I set up my menus

after I select my theme?

Chacha102

It shouldn't matter

But it can't hurt if you stick to after you select your theme

timshutes

yeah, we'll see if it happens again. hopefully it's not related to godaddy -- it is weird that it's not happening at all on my local build

ok I'll do that and update the question afterward

thanks for your help

Chacha102

When you get into very complicated themes, it is best to select the theme, and THEN make customizations.

No problem. Its what I do for a living, kinda

timshutes

yeah - I mean I've been building this custom theme for a while and testing - I'm at the deployment stage, and this bug came up. thanks again
