Send array with ajax request to php

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 :-)

Try this

var array = ["9", "ques_5", "19", "ques_4"];
console.log(array.join(","));

above code will output string with comma separated like 9,ques_5,19,ques_4then paste it to ajax call.

And then in php explode that string.

Other possible solutions.

First

var obj = { 'item1': 'value1', 'item2': 'value2' };

$.ajax(
{
    type:  'post', 
    cache:  false ,
    url:  'test/result.php',
    data:  { result : JSON.stringify(obj) },
    success: function(resp)
    {
        alert(resp);
    } 
});

Second

var a = $.JSON.encode(obj);

$.ajax(
{
    type:  'post', 
    cache:  false ,
    url:  'test/result.php',
    data:  { result : a },
    success: function(resp)
    {
        alert(resp);
    } 
});

In PHP File

<?php
    $json = $_POST["data"]
    var_dump(json_decode($json));
?>

If you want to send key value pairs, which is what I am seeing, it would be better to use a PHP JSON library (like this one... http://php.net/manual/en/book.json.php)

Then you can send actual key value pairs, using JSON format like... {"ques_5" : "19", "ques_4": "19"}
