Meta Box

Hi Long,
Thanks for the reply. I have changed the conditional logic. Now the fields are showing on the frontend. But if, I edit the field values and click submit, a success message is displayed, but the values are not changes in the database. So, it is a bit confusing, maybe I am doing something wrong.
But since I am short of time to complete the project. So, for the time being I have purchased the Livecanvas plugin, which is very easy and user-friendly for the clients, to edit the static pages on the frontend. So, I will give Metabox frontend submission a try in future and will get back to you, if needed.

It is a sort of case study request, if possible.
Kindly create a guide containing simple examples on various custom fields and how to display those in MB Views. It will be very helpful, to cut the time, which is wasted in searching various online sources to do simple things, but unfortunately, there are very minimal tutorials/resources, when it comes to Metabox, as compared to ACF, Toolset and Jetengine.

Thanks, that worked.
Kindly also advise, on how to display the image in twig, like in the above example, there is one custom field with ID event_speaker_image. How to display that?

Further, is it possible, to write simple PHP instead of twig in the views? I tried to write PHP code, but the output is the code itself and not the result.

I have found a cookbook regarding functionality of twig with customfields, but it is more focused on ACF, so not much of help.
