User defined menus

Replaces old-style internal links with new pipe-split links.

There is already a solution to create, manage and use menus from WikkaMenus. I was troubled because it allows any WikiUser to change any menu, possibly changing so the interface used by the other users. Also I wanted something closer from the users, allowing them to design icon-menus if they want.

An alternate solution

So I came with a simple idea that any user could simply define a WikiPage named UserLogonMenu where he would simply type in the menu he wants using the standard wikka formatting. He may define the ACLs of this menu page as he wish. This solution is perfectly compliant with the WikkaMenulets too.

The header.php and the stylesheet needs to be slightly changed so that when the system finds a page named UserLogonMenu it simply use it as the user menu. It also allows the admin to design an alternate GuestMenu for unidentified users.
I decided to have a class different from the "header" one but this is not mandatory.

The code

This code relies on the ExistsPage()function available from 1.1.6.0.
It also include the LoggedUsersHomepage proposal.

New header.php - the lines commented by only if you wish a different presentation are not mandatory
<?php
    $message = $this->GetMessage();
    $user = $this->GetUser();
      $site_base = $this->GetConfigValue("base_url");
      if ( substr_count($site_base, 'wikka.php?wakka=') > 0 ) $site_base = substr($site_base,0,-16);
?>

<div class="header">
    <h2><?php echo $this->config["wakka_name"] ?> : <a href="<?php echo $this->href("", "TextSearch", "phrase=").urlencode($this->GetPageTag()); ?>"><?php echo $this->GetPageTag(); ?></a></h2>
    <?php
        if ($this->GetUser()) {
            $username=$this->GetUserName();
            $usermenu=$username."Menu";
            if ($this->ExistsPage($usermenu)) {
                $themenu=$this->LoadPage($usermenu);
                echo '</div><div class="menuicon">'; //only if you wish a different presentation
                echo $this->Format($themenu["body"]);
                echo "</div>"; //only if you wish a different presentation
            }
            else
            {
                echo ($this->GetUser() ? $this->Link($this->config["logged_in_homepage"]) : $this->Link($this->config["root_page"]))." :: ";
                echo $this->config["logged_in_navigation_links"] ? $this->Format($this->config["logged_in_navigation_links"])." :: " : "";
                echo "You are ".$this->Format($this->GetUserName());
            }
        } else {
            if ($this->ExistsPage(GuestMenu)) {
                echo '</div><div class="menuicon">';  //only if you wish a different presentation
                $themenu=$this->LoadPage(GuestMenu);
                echo $this->Format($themenu["body"]);
                echo "</div>";  //only if you wish a different presentation
            }
            else
            {
                echo $this->Link($this->config["root_page"])." :: ";
                echo $this->config["navigation_links"] ? $this->Format($this->config["navigation_links"]) : "";
            }
        }
    ?>  
</div>


Add something like this in the style sheet file if you want a different presentation for these menus
.menuicon {  
    color: #333;
    background: #CCCCCC;
    text-align: center;  
}


Menu samples

You may have something like:
[[HomePage | Home]] - {{edit}} - [[PageIndex | Index]] - [[Docs:FormattingRules | Writing rules]] - SandBox - [[UserSettings | Settings]] - [[UserName | My Home]]

Or more sexy like (I already use an icons folder but the user could upload its own icons using the files action:
{{image alt="Home Page" title="Home Page" url="icons/32/home.png" link="HomePage"}}{{imageedit alt="Edit Page" title="Edit this page" url="icons/32/pen.png"}}{{image alt="Index" title="Pages Index" url="icons/32/dictionary.png" link="PageIndex"}}{{image alt="Formatting Rules" title="Formatting Rules" url="icons/32/Whiteboard.png" link="FormattingRules"}}{{image alt="Sandbox" title="Sandbox" url="icons/32/paddle.png" link="SandBox"}}{{image alt="User Settings" title="Change Settings/Logout" url="icons/32/kgpg.png" link="UserSettings"}}{{image alt="User Page" title="My own page" url="icons/32/identity.png" link="UserName"}}
Here is how this one here above looks like :

The page shown here above is what we call our WorkSpace and it also links to various pages through a dedicated menu: guess where these icons link to?



Look at SmiliesAction for a simpler image action, and for a workaround for IE handling of PNG's transparency
