Register/Login Notworking android/PHP -

hi guys set table on 000webhost. set column id, name, username, age , password. reason username not show in table when run code register , im not sure error is. here code register.php:

<?php $con = mysqli_connect("*****", "****", "*****", "****");  $name = $_post["name"]; $age = $_post["age"]; $username = $_post["username"]; $password = $_post["password"];  $statement = mysqli_prepare($con, "insert user (name, username, age, password) values (?, ?, ?, ?)"); mysqli_stmt_bind_param($statement, "siss", $name, $username, $age, $password); mysqli_stmt_execute($statement);  $response = array(); $response["success"] = true;    echo json_encode($response); ?> 

as stated in comments:

you're trying insert string using i parameter being integer.

the order matters when binding.

you need change present parameters ssis while making sure age column indeed integer type.

checking errors on query have told it.

i hope you're not storing plain text passwords. use password_hash() if plan on going live this.

sorry bearer of bad news, hacked should case.

using prepared statement without using safe password hashing function won't guarantee site being compromised.
