posting an array using JQuery .post()

Question

so I am rather new to the whole .post() experience with jquery.

I have only experience POSTing input values so far. What I want to do is POST an array.

which is a standard array of a list of numbers. The end goal being: performing a query with these values.

Could somebody explain to me very basically how using JQuery .post() I can post my array?

many thanks,

Is $student_numbers a PHP variable? It looks like. Maybe you should post some code of what you already did. — DanielB

i've just pre-constructed my array in PHP from a couple of queries. — dapperwaterbuffalo

with $.post() you send data from your client (JavaScript) to your server (PHP). But you already have the variable on your server. What exactly you are trying to do? — DanielB

Thats not very clear from your question. I think the answers already given should point you in the right direction. — DanielB

Check jQuery.post(). There is an example for posting arrays.

EDITED: Example is like;

$.post("test.php", { 'choices[]': ["Jon", "Susan"] });

So replace the Jon,Susan part with your array, e.g. $.post('test.php', { 'choices[]' : your_array_variable_here }

I guess, without going into great detail, the answer on you question is called JSON.

The process is easy:

Backend (PHP) Array -> encode as JSON string -> send that JSON string to the browser -> decode the JSON string as Javascript Array

but the issue is, its a university server and I was under the impression not all servers have JSON serialization supported, which I have no idea if this does, so I was hoping there was a different solution.
