template_hook and Blank Page

[sheppardzwc]

Hi all --

A bit new to the whole 'registering' variable scene. Trying to append to a template hook in the modifyoptions template (usercp_options_start) and it's giving me a very pretty stark white page. Any clue what I'm doing wrong here? (this is on the profile_editoptions_start hook)

PHP Code:

<?php

if($vbulletin->options['username_markup_enabled']) {
    $groups = explode(',', $vbulletin->options['username_markup_groupids']);
    $userid = $vbulletin->userinfo['userid'];
    if(in_array($vbulletin->userinfo['usergroupid'], $groups) || $vbulletin->options['username_markup_groupids'] == 'ALL') {
        $colors = explode(',', $vbulletin->options['username_markup_colors']);
        $styling = explode(',', $vbulletin->options['username_markup_styling']);
        foreach($styling as $style) {
            if($style == 'blink') {
                $blink = true;
            } else if($style == 'bold') {
                $bold = true;
            } else if($style == 'italics') {
                $italics = true;
            } else if($style == 'marquee') {
                $marquee = true;
            } else if($style == 'strikethrough') {
                $strike = true;
            } else {
                die('Bah. You configured an invalid style type. (' . $style . ') Go fix that.<br /><br />Settings -> Options -> Username Markup Settings');
            }
        }
        if($blink || $bold || $italics || $marquee || $strike) {
            $mchecked = $vbulletin->db->query_first("SELECT markup FROM vb4." . TABLE_PREFIX . "user WHERE userid='$userid'");
            $mchecked = $mchecked['markup'];
            if(empty($mchecked)) {
                $mchecked = array();
                $mchecked['blink'] = NULL;
                $mchecked['bold'] = NULL;
                $mchecked['italics'] = NULL;
                $mchecked['marquee'] = NULL;
                $mchecked['strikethrough'] = NULL;
            } else {
                $mchecked = explode(',', $mchecked);
                $checked = 'checked=\"checked\"';
                foreach($mchecked as $num => $value) {
                    if($num == 0) {
                        if($value) {
                            $mchecked['blink'] = $checked;
                        } else {
                            $mchecked['blink'] = NULL;
                        }
                    } else if($num == 1) {
                        if($value) {
                            $mchecked['bold'] = $checked;
                        } else {
                            $mchecked['bold'] = NULL;
                        }
                    } else if($num == 2) {
                        if($value) {
                            $mchecked['italics'] = $checked;
                        } else {
                            $mchecked['italics'] = NULL;
                        }
                    } else if($num == 3) {
                        if($value) {

                    } else if($num == 4) {
                        if($value) {
                            $mchecked['strike'] = $checked;
                        } else {
                            $mchecked['strike'] = NULL;
                        }
                    } else {
                        die('Something went wrong.');
                    }
                }
            }
            $menabled = $vbulletin->db->query_first("SELECT markup_enabled FROM vb4." . TABLE_PREFIX . "user WHERE userid='$userid'");
            $menabled = $menabled['markup_enabled'];
            if($menabled) {
                $mchecked['enabled'] = true;
            }
        } else {
            $disabled = true;
        }
    $templater = vB_Template::create('usernamemarkup_editoptions');
    $templater->register('blink', $blink);
    $templater->register('bold', $bold);
    $templater->register('italics', $italics);
