Checking whether insertion of new row in mySql database was successful using php, and returning the newly inserted row -


i have php code registers new users android app. have declared username field unique, if duplicate username entered generate error @ insertion. how check whether insertion executed succesfully , how proceed returning newly added row app. here code, should write in if() statement?

$con = mysqli_connect("", "", "", "");  $username = $_post["username"]; $password = $_post["password"]; $imagelink = $_post["imagelink"]; $name = $_post["name"]; $dob = $_post["dob"]; $mobile = $_post["mobile"]; $email = $_post["email"]; $currency = $_post["currency"]; $location = $_post["location"];   $statement = mysqli_prepare($con, "insert a8768135_testdb.uzer (username, password, imagelink, name, dob, mobile, email, currency, location) values (?, ?, ?, ?, ?, ?, ?, ?, ?)"); mysqli_stmt_bind_param($statement, "sssssssss", $username, $password, $imagelink, $name, $dob, $mobile, $email, $currency, $location); mysqli_stmt_execute($statement);   if() {     $statemente = mysqli_prepare($con, "select * a8768135_testdb.uzer username = ? , password = ?");     mysqli_stmt_bind_param($statemente, "ss", $username, $password);     mysqli_stmt_execute($statemente);      mysqli_stmt_store_result($statemente);     mysqli_stmt_bind_result($statemente, $userid, $username, $password, $imagelink, $name, $dob, $mobile, $email, $currency, $location);      $user = array();      while (mysqli_stmt_fetch($statemente)) {         $user["username"] = $username;         $user["password"] = $password;         $user["imagelink"] = $imagelink;         $user["name"] = $name;         $user["dob"] = $dob;         $user["mobile"] = $mobile;         $user["email"] = $email;         $user["currency"] = $currency;         $user["location"] = $location;     }      echo json_encode($user); }   mysqli_close($con);

use mysqli_insert_id:

mysqli_insert_id($con);

the result last id (auto increment value) record created, return of value 0 means no new record added/inserted

your code should this:

$statement = mysqli_prepare($con, "insert a8768135_testdb.uzer (username, password, imagelink, name, dob, mobile, email, currency, location) values (?, ?, ?, ?, ?, ?, ?, ?, ?)"); mysqli_stmt_bind_param($statement, "sssssssss", $username, $password, $imagelink, $name, $dob, $mobile, $email, $currency, $location); mysqli_stmt_execute($statement);  if(mysqli_insert_id($con) > 0) { ...... }
