How to Load a JavaScript Array Items To MySQL Database Using jQuery Ajax

Question

I Have a simple array which looks like

var arr = ["foo", "2015/11/04", "Jill", "Smith", "60"]
var serializedArr = JSON.stringify( arr );

now can you please let me know how I can load the serializedArr into the data in following ajax request?

var upload = $.ajax({
    type: "POST",
    url: "assets/.../loader.php",
    data: data,
    cache: false,
    beforeSend: function() {
    }
});

and also how to read the data on server side PHP file? Thanks

var upload = $.ajax({
    type: "POST",
    url: "assets/.../loader.php",
    data: {array:serializedArr},// pass here{key:value,key:value,...}
    cache: false,
    beforeSend: function() {
    }
});

In php

$array = json_decode($_POST['array']);
print_r($array);// this will get back the array which was encoded.

You have to decode the array because, array is encoded(JSON.stringify(arr))

Thanks Niranjan, just on PHP side can you please let me know incase of having a variable like $foo how can I get it's value from the $array I mean the first item in the arr

Niranjan N Raju Over a year ago

use foreach() on $array, and get the values .

Behseini Over a year ago

why foreach()? I just need the first element? in a only one set of array

Narendrasingh Sisodia Over a year ago

echo $array[0];. But this is simply spoon feeding nothing else

Niranjan N Raju Over a year ago

if you want only 1 element, then dont encode r aont use array. just send as normal variable.
