Setting server side object variables

Wappler General How To
#24

Hi @mebeingken, did you find a solution for your original question-1. I have a nested json post’d from client-side form to server-side. On the server side, I have to process this json and literally change one value conditionally.

To my limited knowledge, I couldn’t find any direct way like $_POST.search_config.terms[1].term_name = “newvalue”. My understanding is, the whole nested json has to be put through a repeat, update during the loop, and has to be re-assigned to a new similar nested variable with output ticked.

Is this the only way, would you know? Thanks!

Well, I actually moved on from that as #2 was solved. Is your json going to be in a textarea input within a post form?

#26

Yes, followed this guide… Send nested JSON with server-side API, using hidden textbox and submitting via form post!

#27

Just to clarify…That seems to describe using multiple inputs (one for each element,) not one with the entire json…which are you doing?

#28

Tried posting entire json, but realised that I had to convert to string on client-side & then decode the json on server-side, and that was too much for me, as currently there are no wappler out-of-the-box formatters for this…

Hence, ended up implementing the multiple inputs technique… The above nested json object is on server side, automatically generated by linking the client-side form.

I have some processing to be applied on this json data, and has to happen on server side. So, trying to achieve that, but looks very tedious as I can’t directly initialise any value in this json data without looping using repeats.

I guess my first thought is – if this json is from a client side api, could you move it to server so you can just deal with it as output from the call?

Or, you can always go the custom formatter route.

I have hit the same dead-end multiple times now - the need to create custom formatter for basic json (from non-apis) encoding/decoding & processing… wish wappler had these out-of-the-box components esp on the server side… :pensive:
