I am doing something like this

$user_select_assets = $pages->find("template=addase");
$borago = $pages->find("template=user, user_select_asset.count!=0")->remove($page);

foreach($borago as $bora) {
    foreach($bora->user_select_asset as $snow) {
        $user_select_assets->remove($snow);
    }
}

return $user_select_assets;
 

but i have some warning

Invalid argument supplied for foreach() in /public_html/wire/modules/Inputfield/InputfieldPage/InputfieldPage.module(116) : eval()'d code on line 5

That's because of ->remove($page);

I removed that part but still error and not working selected to skip.

Your variable names makes me a little dizzy. For better responds on this forum maybe you can make clear & proper english/american variable names.

This is one of those situations where it would be awfully helpful to really see what's the full context, pages and fields you've got etc. but based on what you've posted here:

That error seems to suggest that your second foreach loop (assuming it's actually on line 5) gets invalid argument, i.e. $bora->user_select_asset isn't something you can iterate with foreach. The main problem here might be the way you're trying to find users; try one of these instead:

// this one:
$borago = $pages->find("template=user, user_select_asset.count!=0, include=all")->remove($page);
// or this one:
$borago = $users->find("user_select_asset.count!=0")->remove($page);

If that doesn't help, I'd suggest that you add a check before second foreach line, where you output something like var_dump($bora), var_dump($bora->user_select_asset) and/or get_class($bora->user_select_asset) just to check what you're actually dealing with.

If echo doesn't work there, try wrapping the command with die() (or writing output to log file, here's one example for implementing that.)

Also: make sure that all your variable and template names are properly written; for an example in your first post you mentioned template name "addAsset", while in your code you're trying to find pages with template "addase". Has the name changed or is it misspelled here?

Here is a final changes

//template "addassets" is where are assets information (Serial, Model, Name, Make )
//template "user" is for users and this template have field "Page" with name "user_select_asset" where i am using also this code in INPUT > PHP Costume Code.

$assets = $pages->find("template=addassets");
$UserAssets = $pages->find("template=user, user_select_asset.count!=0, include=all")->remove($page);

foreach($UserAssets as $AssetSelected) {
    foreach($AssetSelected->user_select_asset as $userA) {
        $assets->remove($userA);
    }
}

return $assets;
 

in output when i edit a User in field Select Asset "user_select_asset"  i can see all assets and i can select one, ok I selected asset with name "Asset1" good and I save a page, than I go to the second user Page to select other asset related to this user there is still Asset1 but some others now is not showing like Asset5 and 6.

thanks.
