You need to place if condition after this line case 'profile_driver': before returning data to web-service.

Try dumping the var_dump($_REQUEST) to check if the id parameter is in request or not OR it is empty.

if(!empty($_REQUEST['id'])) {
   echo 'Please enter id';
} else {
   // your rest of the code goes here
}

Also you need to change the loop.

$data = array("api_status" => 1, "api_message" => "success", "result" => "");
if( $loop->have_posts() ) :
    while($loop->have_posts()) : $loop->the_post();
        $data['result'][] = array(
            "id"        => get_the_ID(),
            "post_name" => get_the_title(),
            "username"  => get_post_meta(get_the_ID(), 'username', true),
            "password"  => get_post_meta(get_the_ID(), 'password', true),
            "email"     => get_post_meta(get_the_ID(), 'email', true),
            "phone"     => get_post_meta(get_the_ID(), 'phone', true),
        );
    endwhile;
endif;
echo  json_encode($data);

oke, its can get the the id but im still get wrong response have u help me ? check my edit script thanks or iam still wrong to place it ? — APSB, Oct 24 '16 at 07:54
@AdamProjo it seems your file contains `var_dump` find var_dump and remove it. then you will get the proper json response. — Noman, Oct 24 '16 at 08:14
