How to pass an array with ajax - php

Question

I'm trying to pass an array with ajax with a post to a php page.
My code js is :
function funzione5(){
var aux2=document.getElementById('f1').value;
$.ajax({type: "POST",
url: "AddMeeting.php",
data: {
'aux':aux,
'aux2':aux2,
'k':k
},
success: {function(data){
console.log(data);
}
},
error: {function(){alert("Error");}}
});
$('#modalMeeting').modal('hide');
}
and the php page is :
<?php
if(strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest')
{
header("Location: Meetings.php");
exit();
}
if(!isset($_COOKIE["id"]))
{
$json_data = array(
'draw' => 0,
'recordsTotal' => 0,
'recordsFiltered' => 0,
'data' => [],
'error' => 'Laravel Error Handler',
);
$json = json_encode($json_data);
echo $json;
exit();
}
include("DB.php"); //dati configurazione del database
$cont = mysqli_real_escape_string($connessione, $_POST["k"]);
$title = mysqli_real_escape_string($connessione,
$_POST["aux[0]"]);
$date = mysqli_real_escape_string($connessione,
$_POST["aux[1]"]);
$place = mysqli_real_escape_string($connessione, $_POST["aux[2]"]);
$topic = mysqli_real_escape_string($connessione, $_POST["aux[3]"]);
$lat = mysqli_real_escape_string($connessione, $_POST["aux[4]"]);
$lng = mysqli_real_escape_string($connessione, $_POST["aux[5]"]);
for($i=6;$i<$cont;$i++)
{ $part_id+$i = mysqli_real_escape_string($connessione,
$_POST["aux[".$i."]"]); }
$card_id = mysqli_real_escape_string($connessione, $_POST["aux2"]);
$id2=$_COOKIE['id'];
echo mysqli_error($connessione);
$sql1=mysqli_query($connessione,"insert into meeting
(card_id,user_id,title,place,date,topic,lat,lng) values
('$card_id','$id2','$title','$place','$date','$topic','$lat','$lng');");
echo mysqli_error($connessione);
$json_data = array(
"result" => 1
);
$json = json_encode($json_data);
echo $json;
?>
Is it correct to pass an array in this way? I checked that in the function "funzione5" the values of the array are set correctly. What could be the problem? Can you explain me how to pass the array? I searched on the web but i didn't find anything.

Currently your params are being passed as "aux" and "aux2", not "aux[0]" as you have it set in PHP. If it's a simple array I suggest simply using a delimiter, so separate the inputs with whatever symbol and then explode it, it seems like that indeed could be done in your example.
