here section of code in php relating everything:
} else if ($tag == 'register') { // request type register new user $response ["success"] = 1; $response ["uid"] = $user ["unique_id"]; $response ["user"] ["name"] = $user ["name"]; $response ["user"] ["username"] = $user ["username"]; $response ["user"] ["email"] = $user ["email"]; $response ["user"] ["zipcode"] = $user ["zipcode"]; $response ["user"] ["password"] = $user ["password"]; $response ["user"] ["created_at"] = $user ["created_at"]; $response ["user"] ["updated_at"] = $user ["updated_at"]; $response ["user"] ["skills"] = $user ["skills"]; // check if user existed if ($db->isuserexisted ( $email )) { // user existed - error response $response ["error"] = 2; $response ["error_msg"] = "user existed"; echo json_encode ( $response ); } else if (! $db->validemail ( $email )) { $response ["error"] = 3; $response ["error_msg"] = "invalid email id"; echo json_encode ( $response ); } else { // store user $user = $db->storeuser ( $name, $email, $password, $unique_id, $dateofbirth, $zipcode, $skills, $username, $updated_at, $created_at ); if ($user) { // user stored $response ["uid"] = $user ["unique_id"]; $response ["user"] ["name"] = $user ["name"]; $response ["user"] ["username"] = $user ["username"]; $response ["user"] ["email"] = $user ["email"]; $response ["user"] ["zipcode"] = $user ["zipcode"]; $response ["user"] ["password"] = $user ["password"]; $response ["user"] ["created_at"] = $user ["created_at"]; $response ["user"] ["updated_at"] = $user ["updated_at"]; $response ["user"] ["skills"] = $user ["skills"]; $response ["user"] ["uid"] = $user ["unique_id"]; mail ( $email, $subject, $message, $headers ); echo json_encode ( $response ); } else { // user failed store $response ["error"] = 1; $response ["error_msg"] = "json error occured in registartion"; echo json_encode ( $response ); } } } and here 1 of functions data:
public function storeuser($name, $email, $username, $password, $zipcode, $skills) { $uuid = uniqid('', true); $hash = $this->hashssha($password); $encrypted_password = $hash["encrypted"]; // encrypted password $salt = $hash["salt"]; // salt $result = mysql_query("insert users(unique_id, name, email, username, encrypted_password, salt, created_at) values('$uuid', '$name', '$email', ' $username','$zipcode', '$skills' '$encrypted_password', '$salt', now())"); // check successful store if ($result) { // user details $uid = mysql_insert_id(); // last inserted id $result = mysql_query("select * users uid = $uid"); // return user details return mysql_fetch_array($result); } else { return false; } } i'm sorry code listed in post. don't know how deep error is, know in between these lines of code.
string res = json.getstring("success"); system.out.println(91); system.out.println(res); if (integer.parseint(res) == 1) { //line 134 of regular user creation said in log cat please me in way possible.
it means success key not exist.
every time set an error should set success false:
$response ["success"] = 0; json has support boolean (true or false) should use it, make parsing easier.
boolean res = json.getboolean("success"); if(res){ //success } you didnt have map each property of user, can build multi dimensional array storing user object directly.
also should echo json once end, avoid invalid json if multiple condition met.
you have along following lines:
$response = array(); ... }else if ($tag == 'register') { // check if user existed if ($db->isuserexisted ( $email )) { $response ["success"] = false; $response ["error_msg"] = "user existed"; echo json_encode ( $response ); } else if (! $db->validemail ( $email )) { $response ["success"] = false; $response ["error_msg"] = "invalid email id"; echo json_encode ( $response ); } else { // store user $user = $db->storeuser ( $name, $email, $password, $unique_id, $dateofbirth, $zipcode, $skills, $username, $updated_at, $created_at ); if ($user) { // user stored // request type register new user $response ["success"] = true; $response ["user_data"] = $user; mail ( $email, $subject, $message, $headers ); echo json_encode ( $response ); } else { $response ["success"] = false; $response ["error_msg"] = "json error occured in registartion"; } } } echo json_encode ( $response );
