Button inside profile page

(@mk-ned)

Hello everyone

i have created theme-my-login-custom.php file in to the plugins folder and have added this code inside it

<?php
function tml_user_register( $user_id ) {
        if ( !empty( $_POST['user_login'] ) )
           $encrypted_key = mb_substr (preg_replace("/[^A-Za-z0-9 ]|\W|\s/", "M",(wp_hash_password($_POST['user_login']))),8,10 );
              update_user_meta( $user_id, 'encrypted_key', $encrypted_key );

}
add_action( 'user_register', 'tml_user_register' );
?>

also

I have copied profile-form.php from templates folder to my themes folder and have added this code inside

<form action="<?php $template->the_action_url( 'key' ); ?>" method="post">
<tr class="tml-key-wrap">
<th><label for="key"><?php _e( 'Key', 'theme-my-login' ); ?></label></th>
<td><input type="text" name="key" id="key" value="<?php echo esc_attr( $profileuser->encrypted_key ); ?>"
disabled="disabled" class="regular-text" />

<input type="submit" value="<?php esc_attr_e( 'Update Key', 'theme-my-login' ); ?>" name="submit1" />

</td></tr>
</form>

and

I have created key-form.php in the theme-my-login/templates folder and have added this code inside

<?php

if (isset($_POST['submit1']))
{
   $encrypted_key = mb_substr (preg_replace("/[^A-Za-z0-9 ]|\W|\s/", "M",(wp_hash_password($_POST['key']))),8,10 );
   update_user_meta( $user_id, 'encrypted_key', $encrypted_key );
}

?>

now when the user is registerd encrypted_key is created and is written in db->wp_usermeta and is also shown on the profile page (it’s good till now ), but if I click on button (the button which have I added, not the mane update profile button) to update the key nothing happens.
