Cannot get Login to work on Android - php

Question

I recently worked with a PHP script that is supposed to hash the password on registration from the android app. The password will hash and be added to the database, but it won't let me login now. There are no error codes coming up either. Here is the code from Android:
public LoginRequest( String username, String password, Response.Listener<String> listener) {
super(Request.Method.POST, REGISTER_REQUEST_URL, listener, null);
params = new HashMap<>();
params.put("password", password);
params.put("username", username);
Here is the PHP script I am supposed to use:
<?php
require("./Password.php");
$con = mysqli_connect("host", "user", "password", "database");
$typeusername = $_POST["username"];
$typepassword = $_POST["password"];
$statement = mysqli_prepare($con, "SELECT * FROM user WHERE username = ?");
mysqli_stmt_bind_param($statement, "s", $username);
mysqli_stmt_execute($statement);
mysqli_stmt_store_result($statement);
mysqli_stmt_bind_result($statement, $userID, $name, $phone, $username, $password, $email);
$response = array();
$response["success"] = false;
while(mysqli_stmt_fetch($statement)){
if (password_verify($typepassword, $password)) {
$response["success"] = true;
$response["name"] = $name;
$response["phone"] = $phone;
$response["username"] = $username;
$response["password"] = $password;
$response["email"] = $email;
}
}
echo json_encode($response);
?>
Update: This is based off of a template for a login PHP file with a few modifications for my needs. This is closer to what the original template looked like:
<?php
require("./Password.php");
$con = mysqli_connect("host", "user", "password", "database");
$username = $_POST["username"];
$password = $_POST["password"];
$statement = mysqli_prepare($con, "SELECT * FROM user WHERE username = ?");
mysqli_stmt_bind_param($statement, "s", $username);
mysqli_stmt_execute($statement);
mysqli_stmt_store_result($statement);
mysqli_stmt_bind_result($statement, $colUserID, $colName, $colPhone, $colUsername, $colPassword, $colEmail);
$response = array();
$response["success"] = false;
while(mysqli_stmt_fetch($statement)){
if (password_verify($password, $colPassword)) {
$response["success"] = true;
$response["name"] = $colName;
$response["phone"] = $colPhone;
$response["username"] = $colUsername;
$response["password"] = $colPassword;
$response["email"] = $colEmail;
}
}
echo json_encode($response);
?>
This is supposed to work with a previous database that I had setup for a tutorial series that this template is based on, but it does not work either. With a regular login PHP code, I can login just fine, but I want to be able to use the hashed passwords in my database.
