Here is a little tutorial on how to add a visibility feature for your members in their UserCP.

Step 1: Go to ACP -> Support Tab - SQL Toolbox and run the following SQL:

ALTER TABLE ibf_members ADD showbar TINYINT( 1 ) default 1

Step 2: Go to ACP -> Look & Feel -> Select Skin (You must use every skin you have)

Create a new template bit called: bbarSettingsForm in group: skin_bottombar with the following content:

Also Note That: Once you have created the template bit in ONE skin, every skin has that template bit, you just then need to copy the following into every skin.

<if test="$this->memberData['showbar'] == 0">
<form action='{parse url="app=bottombar" base="public"}' method='post' enctype='multipart/form-data' id='postingform' onsubmit='return ValidateForm()' name='REPLIER'>
<input type='hidden' name='module' value='bbarsettings' />
<input type='hidden' name='section' value='settings' />
<input type='hidden' name='cmd' value='showbar' />
<input type='submit' class='input_submit' value='Show The Bottom Bar'/>
</form>
<else />
<form action='{parse url="app=bottombar" base="public"}' method='post' enctype='multipart/form-data' id='postingform' onsubmit='return ValidateForm()' name='REPLIER'>
<input type='hidden' name='module' value='bbarsettings' />
<input type='hidden' name='section' value='settings' />
<input type='hidden' name='cmd' value='hidebar' />
<input type='submit' class='input_submit' value='Hide The Bottom Bar'/>
</form>
</if>

Step 3: Open up FTP and go to Forums Dir -> admin -> applications_addon -> other -> bottombar -> sources -> hooks.php

Inside that file, Find:

public function getHookOutput() 
{
	//-----------------------------------------
	// Member only
	//-----------------------------------------

	if ( ! $this->member->getProperty('member_id') )
	{
		return '';
	}

	//-----------------------------------------
	// Something to return
	//-----------------------------------------

	return $this->registry->output->getTemplate('bottombar')->showBottomBar();
}

Replace All With:

       public function getHookOutput()
       {
               if ( $this->memberData['showbar'] == 1 )
               {

               //-----------------------------------------
               // Member only
               //-----------------------------------------

               /*if ( ! $this->member->getProperty('member_id') )
               {
                       return '';
               }*/

               //-----------------------------------------
               // Something to return
               //-----------------------------------------

               return $this->registry->output->getTemplate('bottombar')->showBottomBar();
               }
               else
               {

               if ( $this->memberData['member_group_id'] == $this->settings['guest_group'] )
               {

               //-----------------------------------------
               // Member only
               //-----------------------------------------

               /*if ( ! $this->member->getProperty('member_id') )
               {
                       return '';
               }*/

               //-----------------------------------------
               // Something to return
               //-----------------------------------------

               return $this->registry->output->getTemplate('bottombar')->showBottomBar();

               }
               else
               {
               return;
               }

               }
       }

Step 4: Open up FTP and go to Forums Dir -> admin -> applications_addon -> other -> bottombar -> extensions,

Create a file called: usercpForms.php and copy the below text into that file:

<?php

if ( !defined( 'IN_IPB' ) )
{
       print "<h1>Incorrect access</h1>You cannot access this file directly. If you have recently upgraded, make sure you upgraded all the relevant files.";
       exit();
}

class usercpForms_bottombar extends public_core_usercp_manualResolver implements interface_usercp
{
       public $tab_name                                  = 'Bottom Bar';
       public $defaultAreaCode                          = 'settings';
       public $ok_message                                  = '';
       public $hide_form_and_save_button = true;
       public $uploadFormMax                          = 0;

       /**

        */
       public function init()
       {
       }

       /**
        * Return links for this tab
        * You may return an empty array or FALSE to not have
        * any links show in the tab.

       function getLinks()
       {

               $array = array();

               $array[] = array(
                        'url'    => 'area=settings',
                        'title'  => 'Bottom Bar',

               );

               return $array;
       }


       /**

       public function runCustomEvent( $currentArea )
       {
               return;
       }

       /**

       public function showForm( $current_area, $errors=array() )
       {
               //-----------------------------------------
               // Where to go, what to see?
               //-----------------------------------------

               switch( $current_area )
               {
                       default:
                       case 'settings':
                               return $this->showFormSettings();
                       break;
               }
       }

       public function saveFormSettings( $member=array() )
       {
               return;
       }
}

Step 5: Open up FTP and go to Forums Dir -> admin -> applications_addon -> other -> bottombar -> modules_public,

Create a new folder called: bbarsettings, then create three(3) files called: defaultSection.php, settings.php and a BLANK index.html file

Step 6: Copy the following content into defaultSection.php and save:

<?php

if ( ! defined( 'IN_IPB' ) )
{
       print "<h1>Incorrect access</h1>You cannot access this file directly. If you have recently upgraded, make sure you upgraded all the relevant files.";
       exit();
}

$DEFAULT_SECTION = 'settings';

Step 7: Copy the following in to settings.php

<?php

if ( ! defined( 'IN_IPB' ) )
{
       print "<h1>Incorrect access</h1>You cannot access this file directly. If you have recently upgraded, make sure you upgraded 'admin.php'.";
       exit();
}

class public_bottombar_bbarsettings_settings extends ipsCommand
{
       /**
        * Main class entry point
        *
        * @access        public
        * @param        object                ipsRegistry reference
        * @return        void                [Outputs to screen]
        */
       public function doExecute( ipsRegistry $registry )
       {
               //-----------------------------------------
               // What to do?
               //-----------------------------------------

               switch($this->request['cmd'])
               {

               //-----------------------------------------
                       case 'showbar':
                               $this->showBar();
                               break;
                       case 'hidebar':
                               $this->hideBar();
                               break;
               }
       }

       /**
        * Show The Bottom Bar
        *
        * @access        public
        * @author        Matt Mecham
        * @return        string                Processed HTML
        */
       public function showBar()
       {
               $showbar = 1;
               $this->DB->update( 'members',  array('showbar'  => $showbar ), "member_id=".$this->memberData['member_id']);
               $this->registry->output->redirectScreen( 'Bottom Bar Visibility Toggled (Showing)', $this->settings[ 'base_url' ].'app=core&module=usercp&tab=bottombar&area=settings'  );
       }

       /**
        * Hide The Bottom Bar
        *
        * @access        public
        * @author        Matt Mecham
        * @return        string                Processed HTML
        */
       public function hideBar()
       {
               $showbar = 0;
               $this->DB->update( 'members',  array('showbar'  => $showbar ), "member_id=".$this->memberData['member_id']);
               $this->registry->output->redirectScreen( 'Bottom Bar Visibility Toggled (Hiding)', $this->settings[ 'base_url' ].'app=core&module=usercp&tab=bottombar&area=settings'  );
       }
}

Step 8: Go to Your UserCP and test the function to see if it is working. If so, you're done with the tutorial and have successfully installed a Member Visibility feature for Bottom Bar Beta 1.
