[crowd]

Hi guys, i have some problems integrating this code into my forum login form.

Im trying to insert this code
do_action('oa_social_login');

into this form script

function login_form(){
global $user_ID;
if(!is_user_logged_in() && $this->options['forum_show_login_form']){
return"<form action='".site_url()."/wp-login.php' method='post'>
<input type='text' name='log' id='log' value='' size='20' class='wpf-input'/><br />
<input type='password' name='pwd' id='pwd' size='20' class='wpf-input'/><br />
<input type='submit' name='submit' value='Login' id='wpf-login-button' class='button' /><br />
<input type='hidden' name='redirect_to' value='".$_SERVER['REQUEST_URI']."'/>
</form>";
}
else return $login_msg;
}

Im a total newbie at php, could you give me a hint how to make it right?
