How do you retrieve a $_POST in inside the options page? I'm currently trying to save some $_POST variables I got from the options page, and save it inside my custom table for the WordPress plugin. However, it won't save.

Here's the code

public static function save_poll(){
    $plugin_id = ID;
    global $_POST;
    if($_POST)
        if($_POST[$plugin_id."_action_taken"])
            self::add_poll($_POST[$plugin_id."_category"], $_POST[$plugin_id."_politician"], $question);
}


 public static function add_poll($cat_id, $politician_id, $question, $answers = ""){
   global $wpdb;
    $wpdb->insert( 
    a14_POLL_QUESTIONS, 
    array( 
        'category_id' => $ca_id, 
        'tag_id'        => $politician_id,
        'question'  => $question
    ));

    return $wpdb->insert_id;
  }

I also tried hooking it up to the 'admin_init' though it still won't budge.. I was trying to look at the internet for hours yet, to no avail. Is there any special way that we could access some $_POST variables?

I am truly sure that these variables wont be registered since I used a unuique ID for it.

This $plugin_id = ID doesn't compute, well this one neither: global $_POST (at least, never seen it...). Please, post a workable code. Only this excerpts don't show the full picture. You are free to edit your Question whenever needed. –  brasofilo Feb 15 '13 at 8:16

+1 per brasofilo, + $_POST is a superglobal so you never have to redeclare it, and it is always there so don't bother to test for it. (Also: use isset() to test whether a variable exists in scope, as it won't raise an error when testing an undeclared variable) –  webaware Feb 15 '13 at 10:14
    
And don't forget to use the third argument, as you might want to prepare the values before inserting it into the DB. Also you should validate and sanitize your data. –  kaiser Feb 15 '13 at 11:20
