I'm a beginner here and i am learning the basic in converting from MySQL to MySQLi. I am currently working on this registration page which I would want to convert to MySQLi. Please advise me how to modify this script, I would prefer the procedural style.
The MySQLi coding is not working because it would notg insert into the database like the MySQL coding would, would appreciate if your can help me.
MYSQL
<?php
error_reporting(1);
$submit = $_POST['submit'];
//form data
$name = mysql_real_escape_string($_POST['name']);
$name2 = mysql_real_escape_string($_POST['name2']);
$email = mysql_real_escape_string($_POST['email']);
$password = mysql_real_escape_string($_POST['password']);
$password2 = mysql_real_escape_string($_POST['password2']);
$email2 = mysql_real_escape_string($_POST['email2']);
$address = mysql_real_escape_string($_POST['address']);
$address2 = mysql_real_escape_string($_POST['address2']);
$address3 = mysql_real_escape_string($_POST['address3']);
$address4 = mysql_real_escape_string($_POST['address4']);
$error = array();
if ($submit) {
//open database
$connect = mysql_connect("localhost", "root", "Passw0rd") or die("Connection Error");
//select database
mysql_select_db("logindb") or die("Selection Error");
//namecheck
$namecheck = mysql_query("SELECT * FROM users WHERE email='{$email}'");
$count = mysql_num_rows($namecheck);
if($count==0) {
}
else

$error[] = "<p><b>User ID taken. Try another?</b></p>";
