Question

I have the following PHP code that created a JSON request from posted form fields.

<?php
if ( isset($_POST['data']['Affiliate'])) { //Where ['data']['Affiliate'] is an array of posted field names of the form.
    $data = $_POST['data'];

    $base = 'https://api.whatever.com/Api?';

    $params = array(
        'Format' => 'json'
        ,'account' => $data['Affiliate']
    );

    $url = $base . http_build_query( $params );
    $result = file_get_contents( $url );
    $result = json_decode( $result );

    echo "<pre>";
    print_r( $result );
    echo "</pre>";
?>

print_r( $result ) prints the following.

stdClass Object
(
    [request] => stdClass Object
        (
            [Format] => json
            [account] => stdClass Object
                (
                    [country] => US
                    [address1] => asdasd
                    [city] => asdasd
                    [zipcode] => asdasd
                    [phone] => asdasd
                )
        )

    [response] => stdClass Object
        (
            [status] => -1
            [data] => 
            [errors] => Array
                (
                    [0] => stdClass Object
                        (
                            [err_code] => 3
                            [err_msg] => A user already exists with this email address.
                            [attribute_name] => Email
                            [publicMessage] => User account or user is not valid.
                        )
                    [1] => stdClass Object
                        (
                            [err_code] => 1
                            [err_msg] => City cannot be blank.
                            [attribute_name] => city
                        )
                )
        )
)

How can i use JQuery Ajax to achieve the same results and print out the array of errors in <li> tags.

Answer 1

I suggest you don’t decode the JSON to a PHP object as you did here, but keep the pure JSON, give that to your AJAX request and then do the decoding client-side (I believe there is a special jquery ajax function that gets and decodes it already for you. See Ravi’s answer for that)

But if you don’t want to do this: why don’t you access the fields of the object you got from json_decode()?
I believe that $result->$response->$errors is the array of errors you are looking for.
