In this tutorial, i will create registration html form with bootstrap 4 library and add server side validation on it. Then store user/student registration form data into MySQL database.

Registration Form in PHP and MySQL with Validation

Follow the below given steps and simple and secure registration form in php and mysql with validation:

  • Step 1 – Create PHP Project
  • Step 2 – Create Database Table And Connect App to DB
  • Step 3 – Create Registration PHP File

Step 1 – Create PHP Project

In step 1, Navigate to your local web server directory. And inside this directory, create one directory. And you can name this folder anything.

Here, I will “demo” the name of this folder. Then open this folder in any text editor (i will use sublime text editor).

Step 2 – Create Database Table And Connect App to DB

In step 2, you need to create database and table. So run the following sql query to create database and table:

CREATE DATABASE my_db;

CREATE TABLE users(
id int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
name varchar(255) NOT NULL,
email varchar(255) NOT NULL,
contact varchar(255) NOT NULL,
password varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Then create a php file that named mydbCon. Which is used to connect phpmyadmin mysql database to project (demo).

So, now create mydbCon file and add the below given code into your file:

<?php

    $hName='localhost'; // host name

    $uName='root';   // database user name

    $password='';   // database password

    $dbName = "my_db"; // database name

    $conn= mysqli_connect($hName,$uName,$password,"$dbName");

      if(!$conn){
          die('Could not Connect MySql Server:' .mysql_error());
      }
?>

Step 3 – Create Registration PHP File

In step 3, create a php file that named register.php. This file will display PHP registration form and store user/student registration from data to MySQL database. Now, you need to add the following registration form code into register.php file:

<?php
  require_once "mydbCon .php";
    if (isset($_POST['signup'])) {
        $name = mysqli_real_escape_string($conn, $_POST['name']);
        $email = mysqli_real_escape_string($conn, $_POST['email']);
        $mobile = mysqli_real_escape_string($conn, $_POST['mobile']);
        $password = mysqli_real_escape_string($conn, $_POST['password']);
        $cpassword = mysqli_real_escape_string($conn, $_POST['cpassword']); 
        if (!preg_match("/^[a-zA-Z ]+$/",$name)) {
            $name_error = "Name must contain only alphabets and space";
        }
        if(!filter_var($email,FILTER_VALIDATE_EMAIL)) {
            $email_error = "Please Enter Valid Email ID";
        }
        if(strlen($password) < 6) {
            $password_error = "Password must be minimum of 6 characters";
        }       
        if(strlen($mobile) < 10) {
            $mobile_error = "Mobile number must be minimum of 10 characters";
        }
        if($password != $cpassword) {
            $cpassword_error = "Password and Confirm Password doesn't match";
        }
        if (!$error) {
            if(mysqli_query($conn, "INSERT INTO users(name, email, mobile ,password) VALUES('" . $name . "', '" . $email . "', '" . $mobile . "', '" . md5($password) . "')")) {
             header("location: register.php");
             exit();
            } else {
               echo "Error: " . $sql . "" . mysqli_error($conn);
            }
        }
        mysqli_close($conn);
    }
?>
