Get The Response From Server In JSON Format Without Using Database?

I am new to server side programming, I have a form and action required is, when user fill the name, address and pin code, submit the from then page should be load (like native from

Solution 1:

You can store your JSON string in a local variable server side and have it returned as the result of a client side AJAX call without having to access a database.

Solution 2:

<?php
session_start();

//Variables
$ext    = '.json';
$me     = isset($_SESSION['me']) ? $_SESSION['me'] : $_SESSION['me'] = rand();
$file   = $me . $ext;

//If we have a post handle our data, write to a json file.
if ($_POST) {
    //Don't need the submit key in our data.
    unset($_POST['submit']);

    //Write to the file.
    $str    = json_encode($_POST);
    $fp     = fopen($file, 'w') or die("can't open file");
    fputs($fp, $str);
    fclose($fp);
}

//Check if there is a file with our session name.
if (file_exists($file)) {
    //Get the file content and json decode it.
    $json   = file_get_contents($file);
    $values = json_decode($json);
}
?>
<!-- Form with pre-populated values, if they are set -->
<form action=""method="post">
    <input type="text" name="name" value="<?php print isset($values->name) ? $values->name : ''; ?>" />
    <input type="text" name="address" value="<?php print isset($values->address) ? $values->address : ''; ?>"/>
    <input type="text" name="pincode" value="<?php print isset($values->pincode) ? $values->pincode : ''; ?>"/>
    <input type="submit" name="submit"/>
</form>

Up to you to make it save tough. But i think that should give you a good idea of the possibilities and how to set this up.

Solution 3:

Maybe what you are looking for is JQuery getJSON, if you don't mind using JQuery library, which I would heavily recommend.

It basically uses AJAX for requesting the json file and parses it:

$.getJSON('https://domain.com/jsonfilelocation/json.json', function(data) {
    // 'data' is your object containing the parsed JSON data
    var new_name = data.name
    var new_address = data.address
    var new_pincode = data.pincode
    // ...

Read the doc link I give you, it's very well written.

Solution 4:

just request the page https://domain.com/jsonfilelocation/json.json when doing your request.
