Save data in to data base from json object? - php

Question

I use this code for get form data in json object. After submit I get this response:
{ user: "asdf", password: "asdfsadf" }
But the problem is i didn't know how to save this in database using php. If any one knows how to save in db please guide me. Any help is appreciated.
HTML code
<form onsubmit='return onSubmit(this)'>
<input name='user' placeholder='user'><br>
<input name='password' type='password' placeholder='password'><br>
<button type='submit'>Try</button>
</form>
Javascript code
function onSubmit( form ){
var data = $(form).serializeArray(); // <-----------
var json = {};
$.each(data, function() {
json[this.name] = this.value || '';
});
$.ajax({
type: "POST",
url: "php/tracker.php",
data: json,
dataType: "json"
});
}

Answer 1

here is html code
<input name='user' placeholder='user'>
<input name='password' type='password' placeholder='password'><br>
<button type='submit'>Try</button>
here is script
<script> $("button").click(function(){
var user = $("input name=user").val();
var password = $("input name=password").val();
var responce_type = "from-1";
$.post('php/tracker.php',{ user:user, password:password,responce_type:responce_type},function(resp){
resp = $.parseJSON(resp);
console.log(resp);
if(resp.status == true)
{
alert("DONE");
}
else
{
alert("error");
}
}) }) </script>
here is php code
that right in
php/tracker.php
this page
<?php
if(isset($_POST['from-1']))
{
$user = $_POST['user'];
$password = $_POST['password'];
//do some thing in php then send back request
echo json_encode(array("Data" => $_POST , "status" => true )) ;
}
else
{
echo json_encode(array("Data" => $_POST , "status" => false)) ;
}
?>
