On a custom post, in the WP admin list all posts: I get a notice:
Notice: Trying to access array offset on value of type null in ...(hidden)... wp-content/plugins/types/application/models/field/service.php on line 47

And then when I edit the custom post:
Warning : Invalid argument supplied for foreach() in ...(hidden)... wp-content/plugins/types-access/vendor/toolset/toolset-common/toolset-forms/classes/class.eforms.php on line 1097

I can't display a select field on the edit page

Hi,

Thank you for contacting us and I'd be happy to assist.

During initial tests on my website, I couldn't reproduce this issue.

Can you please share temporary admin login details, so that I can see how this post type and it's custom fields are set up?
( please also specify the name of the custom post type )

Note: Your next reply will be private and though no changes will be made on your website, please make a complete backup copy, before sharing the access details.

regards,
Waqar

Thank you for sharing these details.

I noticed that the "Introduction" field is a multi-lines type field and Toolset Types plugin doesn't support showing this type of field in the post list admin column.

Since the website is using the "Admin Columns Pro" plugin to show these field columns, any error/warning that is shown, as a result, should be reported to that plugin's official support team so that it can be fixed.

I hope this helps.

ok, thanks, this resolve the first part, but there are still some errors on the edit part:

Invalid argument supplied for foreach() in /var/www/clients/client2/web8/web/dev-Baf3Kh/wp-content/plugins/types-access/vendor/toolset/toolset-common/toolset-forms/classes/class.eforms.php on line 1097

on the same page, under the relation information:
Warning: Invalid argument supplied for foreach() in /var/www/clients/client2/web8/web/dev-Baf3Kh/wp-content/plugins/types-access/vendor/toolset/toolset-common/toolset-forms/classes/class.eforms.php on line 1097

Thanks for the update.

I noticed that in your theme's "functions.php" file, the "wpt_field_options" filter is being used.

But the function for that filter is returning an empty value, at line# 345 and 351:

return "";

Changing those lines to return "$options" should fix those warnings:

return $options;

My issue is resolved now. Thank you!
