Struggling with Syntax and homepage URL

[ankh2054]

Hi All,

I really seem to be struggling with the syntax of process wire, could anyone point me in the right directoin of some good documents or tutorials to read.

I am trying to link back to my homepage / via the below and can't get it to work.

<a class="navbar-brand" href="<?php echo $pages->get('/') ?>"><?php echo $pages->get("/site-settings/")->site_title; ?></a>

What does everyone else use to go back to the root URL?

thanks

Not sure why  and how, but I seem to have tried  href="/" and now it works. Must not of uploaded changes. oops.

Any documentation of syntax would really help me.  As a non PHP coder, I struggle to understand when to use 

<?php ,  {, ", ', 

etc....

thank

$pages->get('/')

just returns the ID of the home page. Try

$pages->get('/')->url

If you are new to PHP then you might find the resources at php.net really useful. There's documentation for the entire language including every function.

These three are a must read in order to use PW

1. $page: http://processwire.com/api/variables/page/
2. $pages: http://processwire.com/api/variables/pages/
3. Selectors: http://processwire.com/api/selectors/

Btw (sorry to be pedantic!) ProcessWire really does not have a syntax (in the sense of MODx syntax, for example). It's all PHP

thanks all for being so patient

Could someone help me with the below, I am trying to show the name of the current logged in user.

<a href="#" class="dropdown-toggle" data-toggle="dropdown"><?php $user->name; ?><b class="caret"></b></a>

Seems that only an echo is missing, <?php echo $user->name; ?>

thanks that worked Just leaving my code, for other people who might struggle like me

<?php if($user->isLoggedin()): ?>
               <li class="dropdown">
                <a href="#" class="dropdown-toggle" data-toggle="dropdown"><?php echo $user->name; ?><b class="caret"></b></a>
                <ul class="dropdown-menu">
                   <li><a href="[[~12]]"><i class="icon-user"></i> My Account</a></li>
                   <li><a href="[[~12]]"><i class="icon-envelope"></i> Inbox <span class="badge badge-info"></span></a></li>
                   <li class="divider"></li>
                   <li><a href="?logout=1" title="Logout"><i class="icon-off"></i> Logout</a></li>
                   
                </ul>
              </il>
            <?php else: ?> 
          
               <li><a href="/register/">Sign up</a></li>
               <li><a href="/login/">Login</a></li>
            

            <?php endif; ?>

Another way to get the homepage url ("root url") is:

<?php
echo $config->urls->root;
?>

@Charles....I see some MODx code left in there: [[~12]]. Won't output anything in PW    . You need something like echo $page->url;

[ankh2054]

haha yes indeed, don't have those pages ready
