Need help in adding UI controls to the plugin - Dev

2 Dec 2009

      Hi,
I'm new to roundcube and I'm customizing it for my university project.
I've created a plugin to add a tab for blacklist in the settingstab. But the
problem is the HTML content is not displaying properly in side the tab. I
have attached the code here with. Is my approach is not correct? How can I
do it efficiantly?(I have analyed the seetings and moruserinfo plugins to
get an idea)
<?php

class moreblacklist extends rcube_plugin
{
  public $task = 'settings';

  function init(){

    $rcmail = rcmail::get_instance();

    $this->register_handler('
plugin.blacklist_sections', array($this, 'blacklist_sections'));
    $this->register_action('plugin.blacklist', array($this, 'blacklist'));
    $this->add_hook('list_prefs_sections', array($this, 'blacklist_link'));
    $this->add_hook('user_preferences', array($this, 'prefs_table'));

    $skin  = $rcmail->config->get('skin');
    $_skin = get_input_value('_skin', RCUBE_INPUT_POST);

    if($_skin != "")
      $skin = $_skin;

    // abort if there are no css adjustments
    if(!file_exists('plugins/moreblacklist/skins/' . $skin .
'/settings.css')){
      if(!file_exists('plugins/moreblacklist/skins/default/settings.css'))

        return;
      else
        $skin = "default";
    }

    $nav_hooks = (array)$rcmail->config->get('settingsnav');
    $nav = array();
    foreach($nav_hooks as $key => $val)
      $nav['settingsnav'][] = $val;

    $rcmail->config->merge($nav);
    $this->include_stylesheet('skins/' . $skin . '/settings.css');
    $browser = new rcube_browser();
    if($browser->ie){
      if($browser->ver < 8)
        $this->include_stylesheet('skins/' . $skin . '/iehacks.css');
      if($browser->ver < 7)
        $this->include_stylesheet('skins/' . $skin . '/ie6hacks.css');
    }

  $this->add_hook('template_object_userprefs', array($this, 'userprefs'));
    $this->add_texts('localization/');
    $rcmail->output->add_label('moreblacklist.blacklist');

  }

  function blacklist()
  {
    $rcmail = rcmail::get_instance();
    $rcmail->output->send("moreblacklist.blacklist");
    exit;
  }

  function blacklist_link($args)
  {
    $temp = array();
    $temp['blacklistlink']['id'] = 'blacklistlink';
    $temp['blacklistlink']['section'] =
$this->gettext('moreblacklist.blacklist');
    $args['list'] = $args['list'] + $temp;

    return $args;
  }

 function blacklist_sections()
  {
    $this->infohtml("");
  }

  function prefs_table($args)
  {
    if ($args['section'] == 'blacklistlink') {
      $args['blocks']['main']['options']['blacklistlink']['title'] = "";
      $args['blocks']['main']['options']['blacklistlink']['content'] =
$this->blacklist_sections("");
    }

    return $args;

  }

//the content genarated by this code is not displaying
function infohtml()
  {
       $table = new html_table(array('cols' => 2, 'cellpadding' => 3));
      $field_id = 'blackselect';
    $table->add('title',  html::label($field_id,
Q($this->gettext('blacklist'))));
    $imap_host = new html_select(array('name' => '_blacklistinf', 'id' =>
$field_id,
      'size' => 20));
    $table->add(null, $imap_host->show());
    $out .= $table->show();

    return $out;
  }

  function userprefs($p)
  {
    $rcmail = rcmail::get_instance();

    (array)$parts = explode(",",$p['parts']);
    foreach($parts as $key => $val)
      $parts[$key] = trim($val);

    (array)$temparr = explode("<fieldset>",$p['content']);
    for($i=1;$i<count($temparr);$i++){

      $temparr[$i] = "<div class=\"settingsplugin\" id=\"" . $parts[$i-1] .
"\"><fieldset>" .
str_replace("</fieldset>","</fieldset></div>",$temparr[$i]);

      if($_GET['_section'] == "blacklistlink" || $_POST['_section'] ==
"blacklistlink"){
    $temparr[$i] = str_replace("<legend />","<legend>" .
$this->gettext('blacklist') . "</legend>",$temparr[$i]);
      }

    }

    $p['content'] = implode($temparr);

    return $p;

  }
}

?>
I would be greatful if some one could help me on this.
Thanks,
Chamila
