I am not so bad experienced with custom fields (and so on), but now I want to check this tutorial (I am german and maybe misunderstood this quick video):
My question is: is it possible to have a json (URL) of an "external source" (some event data with table view and single view) and call it through my WordPress into my Meta Box custom fields and update this regularly?
I am a little bit lost because I don't find the right places and where the new field "meta_box" should be.
I hope you can give me some hints and could explain a little bit more "not so quick", but step by step.
Thanks in advance.
I think it is possible. You can create a custom code on your site to fetch the data from an external source then update it to the field value. The prebuilt field
meta_box is created by Meta Box plugin. You can get the custom field value by accessing this field.
If you want to do the customization job, please contact us here https://metabox.io/contact/.
This is not the answer I wanted to get. There is no budget for external customization because it is a charity project.
I would like to have more details in your explanation and in the documentation. I can't follow your instructions, sorry.
And what does it mean "You think it is possible"? You don't know if it is possible?
Would appreciate to have more details (overall) in documentation and support answers because I have to do it on my own. And additionally I want to learn it for next times. Sorry for not hiring you, but this is out of budget. I need more help, please. Therefore I asked for step by step explanations. Thanks.
It is possible that means the extension MB Rest API does not have an option to fetch data from an external source and update its data to the custom field and it can be done with more custom code. It is also beyond the scope of support of this extension.
