[RESOLVED] username password help

i made the option for username password retype password on my form how can i make it so wen the information is processed it will make sure both passwords match and give u a popup warning if they dont?

When the forum is submitted, read the 'newpassword' and 'confirmnewpassword' fields, compare them, and depending upon that, you can show a message or continue with submission of the form.

All you need is a simple string comparision:

PHP Code:

---

if ($_POST['password'] != $_POST['confirm_password']) {
  /* passwords don't match - redirect back to the form */
} 


---

You can also use client side Javascript to check this before the form is submitted to your script.

Code:

---

<script type="text/javascript">
<!--
    function check_pw(theForm)
    {
        if(theForm.password.value != theForm.confirm_password.value)
        {
            alert('Your passwords do not match.');
            theForm.password.value = '';
            theForm.confirm_password.value = '';
            theForm.password.setFocus();
           
            return false;
        }
       
        return true;
    }
//-->
</script>
..

..

<form onsubmit="return check_pw(this);">

---

You should also still check in the PHP script even if you yuse javascript to check as this can be bypassed.
