Title: Extension: Hide Additional Fields – Warning: in_array() Last modified: June 26, 2020 --- # Extension: Hide Additional Fields – Warning: in_array() * Resolved [stzlichtenbrg](https://wordpress.org/support/users/stzlichtenbrg/) * (@stzlichtenbrg) * [5 years, 11 months ago](https://wordpress.org/support/topic/extension-hide-additional-fields-warning-in_array/) * Hi, we are using Events Calendar with Avada theme. I configured 2 additional fields (contact details for submitted community events) which should be hidden on the single events page. Therefore the Events Calendar PRO Extension: Hide Additional Fields Version 1.0.0 is installed. The fields are hidden, but I get the following error: `Warning: in_array() expects parameter 2 to be array, bool given in /www/htdocs/w0129062/website.com/wp-content/plugins/tribe-ext-hide-additional- fields/src/views/community-field-options.php on line 28` name=”custom-hidden[]” > Phone number Error is also visible in the backend as logged in user. What do I have to change at the current extension or how can I achieve, that these additional fields are not displayed at the single events page without using the extension? * Thanks for your help!

If you need help with that, just let me know which fields exactly you want to get rid of, so I can help you with the CSS snippet. * Thanks. * Thread Starter [stzlichtenbrg](https://wordpress.org/support/users/stzlichtenbrg/) * (@stzlichtenbrg) * [5 years, 9 months ago](https://wordpress.org/support/topic/extension-hide-additional-fields-warning-in_array/#post-13201085) * Hi alaasalama, sorry for my delayed reply and thanks a lot for your suggestion. This is exactly what I did but as the additional fields contain contact data of the event organizer, I would prefer to hide these sensitive information and not only to make it invisible as it is still displayed in the source code. Any hints how I can achieve this would be very appreciated. * Best regards * [Jaime](https://wordpress.org/support/users/jaimemarchwinski/) * (@jaimemarchwinski) * [5 years, 9 months ago](https://wordpress.org/support/topic/extension-hide-additional-fields-warning-in_array/#post-13218063) * Hi [@stzlichtenbrg](https://wordpress.org/support/users/stzlichtenbrg/) * If you don’t want to use CSS here, you’ll want to create a template override and hide the data that way. * You can read more about template overrides here: [https://theeventscalendar.com/knowledgebase/k/customizing-template-files/](https://theeventscalendar.com/knowledgebase/k/customizing-template-files/) [https://theeventscalendar.com/knowledgebase/k/custom-templates-for-the-updated-calendar-views/](https://theeventscalendar.com/knowledgebase/k/custom-templates-for-the-updated-calendar-views/) * I hope that helps! * Thanks, Jaime * Thread Starter [stzlichtenbrg](https://wordpress.org/support/users/stzlichtenbrg/) * (@stzlichtenbrg) * [5 years, 9 months ago](https://wordpress.org/support/topic/extension-hide-additional-fields-warning-in_array/#post-13238874) * Hi Jaime Thanks you very much for the links. This seems to bee more complicated than just hiding the fields via CSS but is more what I want to achieve. Will test this when I have some time. * Thanks stzlichtenbrg * [Jaime](https://wordpress.org/support/users/jaimemarchwinski/) * (@jaimemarchwinski) * [5 years, 9 months ago](https://wordpress.org/support/topic/extension-hide-additional-fields-warning-in_array/#post-13245507) * Hi [@stzlichtenbrg](https://wordpress.org/support/users/stzlichtenbrg/) * Okay, sounds good.
