php - Form information not being 'seen' by MySQL -

-

i've made new log in / register template uses css3 , html, yet had working form, basic, before this. decided make 'form' should this: http://www.script-tutorials.com/css 3-modal-popups/

now, use form handle registration:

<!-- popup form #2 -->     <a href="#x" class="overlay" id="join_form"></a>     <div class="popup">       <h2>sign up</h2>       <p>         please enter details here.       </p>       <div>    <form action="register.php" action="post">         <label for="username">username</label>         <input type="text" id="username" placeholder="max 32 characters" name="username" />       </div>       <div>         <label for="password">password</label>         <input type="password" id="password" placeholder="password" name="password" />       </div>       <div>         <label for="lastname">lastname</label>         <input type="text" id="lastname" placeholder="lastname" name="lastname" />       </div>       <div>         <label for="email">e-mail</label>         <input type="email" id="email" placeholder="example@hotmail.com" name="email" />       </div>       <input type="submit" value="join community" />&nbsp;&nbsp;&nbsp;or&nbsp;&nbsp;&nbsp;    </form>

yet when test form, data stored (my register.php file comes if-statement), yet displays nothing. (no username, (password still gets hashed / stored, though i'm not sure if it's handling it), last name , e-mail.

i've checked , double checked 'name' attributes' value in register.php file. , correct.

pretty sure accessing form values using $_post. problem in form tag setting action twice, 1 of correct i.e. action="register.php" , other action="post" incorrect.

try:

<form action="register.php" method="post">
