BEEN at this for days. Using jquery ajax to perform somethings and trying to get a json encoded response from my server. Not sure why this is now working for me.
Below is my Javascript function
function checkFriendsEmail(friendsEmail){
var request = $.ajax({
url : 'http://localhost/loginsentology/serverside/checkfriendexist2.php',
type: 'POST',
data: {
'checkfriend' : 'checkfriend',
'friendsemail' : friendsEmail,
},
success: function(data) {
console.log(data); <<<-- Comes back to my console as a JSON obj
console.log(data.nouser); <<-- Comes back undefined
}
I get this result in my console. { "nouser" : ["noUserExist"] } <<<----- How do I grab this.
MY PHP is below
$fdarray = array();
$_db = DB::getInstance();
$_query = $_db->query('SELECT * FROM users WHERE email = ? ', array($_POST['friendsemail']));
$results = $_query->results();
$numberOfRows = $_db->numberOfRows();
if ($numberOfRows == 0) {
//$noUserExist = 'NoUserExist';
$fdarray['nouser'] = array();
array_push($fdarray['nouser'], 'noUserExist');
echo json_encode($fdarray);
return false;
}
else {
//friends email exist in users db --> now we must check to see if friend has devices
$friendsEmail = $results[0]->email;
if ($_POST['friendsemail'] == $friendsEmail) {
$id = $results[0]->id;
$_db2 = DB::getInstance();
$_query2 = $_db2->query('SELECT * FROM devices WHERE userid = ? ', array($id));
$results2 = $_query2->results();
$numberOfRows2 = $_db2->numberOfRows();
if ($numberOfRows2 == 0) {
//user has no devices attached to name
$fdarray['userexist'] = array();
$fdarray['nodevices'] = array();
array_push($fdarray['userexist'], true);
array_push($fdarray['nodevices'], 'noDevicesForUser');
echo json_encode($fdarray);
return false;
}
else {
$fdarray['userexist'] = array();
$fdarray['devices'] = array();
array_push($fdarray['userexist'], true);
for ($i = 0; $i < $numberOfRows2; $i++) {
array_push($fdarray['devices'], $results2[$i]->devicename);
}
//end for statement
}
//end number of rows2
echo json_encode($fdarray);
}
//end firendsemail == firendsemail
}
