Dynamic filtering from external function with Datatable

Question

I need to filter using dynamic parameters from a form post. But I dont know how to send the parmeters with a dynamic generated name... see code below hope it explains my problem.

$('#kt_search').on('click', function(e) {
e.preventDefault();
var frm_data = $('#searchFrom').serializeArray();
$.each(frm_data, function(key, val) {

myData.comercial    = 23; //THIS WORKS

myData.val.name     = val.value; // THIS IS INCORRECT
});

table.table().draw();
});

Assuming val.name holds the name of the property, you can access the dynamic property like so:

myData[val.name]

So, to set the value:

myData[val.name] = val.value;

Here is a fiddle demo: https://jsfiddle.net/zephyr_hex/o98ykn72/4/

myData[val.name] = val.value; in console.log this shows the parameters with the value but how to I get the value in the posted file?

so in the destination php file I would use $post_comercial = $_REQUEST["comercial"]; $post_estado = $_REQUEST["estado"]; but its not working what am I missing

when a field is empty I get an error: Uncaught TypeError: Cannot read property 'length' of undefined at _fnAjaxUpdateDraw (datatables.bundle.js:4126)

@vance = seems like you have several other issues going on, and you may need to work through them one by one. The answer I've posted above should resolve the question in your post.
