I want to make a user registration and found there some Templates and Tutorials. The registration basically works but i really want a field where the user has to repeat his password. My problem now is how to check if the two fields (password and passwordrepeat) are the same? Here is my code:

  • You're already using an API that supports **prepared statements** with bounded variable input, you should utilize parameterized queries with placeholders (prepared statements) to protect your database against [SQL-injection](http://stackoverflow.com/q/60174/)! Get started with [`mysqli::prepare()`](http://php.net/mysqli.prepare) and [`mysqli_stmt::bind_param()`](http://php.net/mysqli-stmt.bind-param). – Qirel Sep 23 '17 at 15:59
  • Using old methods of encrypting passwords (such as `sha1`, `md5`) are **poor methods of hashing** - you should use newer methods for hashing your passwords. PHP has a built-in [`password_hash()`](http://php.net/manual/en/function.password-hash.php) function which is a lot more secure! – Qirel Sep 23 '17 at 15:59
  • To check if two things are equal, you compare them. `$a == $b` is true if they are equal. Have a look at [**The 3 different equals**](https://stackoverflow.com/questions/2063480/the-3-different-equals) – Qirel Sep 23 '17 at 16:00

Just compare the two POST vars and check if they are equals.

if($_POST['password'] === $_POST['passwordrepeat']){
    /* Do your registration */
} else {
    /* return an error */
}

Obviously you have to check for the existence of those vars, and do all the security stuff.

Try this:

HTML Code:

<input type="password" name="pass" id="pass" min="6" max="30" required="" placeholder="Mot de passe">
<input type="password" name="cpass" id="cpass" min="6" max="30" required="" placeholder="Confirmation">

PHP Code:

<?php
    if (!empty($_POST['pass']) AND !empty($_POST['cpass']) AND $_POST['pass'] == $_POST['cpass'])
    {   
        echo "ok";
    }
    else
    {
        include("index.php");
        ?>
        <style>
        #cpass
        {
            border: 3px solid red;
            border-radius:6px;
        }
        </style>
        <?php
    }
    ?>

You can also use JS.
