Send array with ajax request to php

Question

I created array like this [\"9\", \"ques_5\", \"19\", \"ques_4\"]. Now I want to send it from JS to PHP but I\'m not getting proper results. My JS code is:

Answer 1

You can pass the data to the PHP script as a JSON object. Assume your JSON object is like:

var stuff ={'key1':'value1','key2':'value2'};

You can pass this object to the php code in two ways:

1. Pass the object as a string:

AJAX call:

$.ajax({
    type    : 'POST',
    url     : 'result.php',
    data    : {result:JSON.stringify(stuff)},
    success : function(response) {
        alert(response);
    }    
});

You can handle the data passed to the result.php as :

$data    = $_POST["result"];
$data    = json_decode("$data", true);

//just echo an item in the array
echo "key1 : ".$data["key1"];

2. Pass the object directly:

AJAX call:

$.ajax({
    type    : 'POST',
    url     : 'result.php',
    data    : stuff,
    success : function(response) {
        alert(response);
    }    
});

Handle the data directly in result.php from $_POST array as :

//just echo an item in the array
echo "key1 : ".$_POST["key1"];

Here I suggest the second method. But you should try both :-)
