Help creating a current link

[matthewmjscott]

Thanks Boogyman!

[matthewmjscott]

Is there some other code required to make that work?

[matthewmjscott]

I found this Smarty-related PHP code which if re-written might help the other code posted by boogyman:

define('SITE_URL' = 'http://localhost/');

$smarty->assign('current_section', current_section());
$smarty->assign('primary_links', build_primary_links();

$smarty->display('index.tpl');

function current_section() {
   // For the purpose of this code, we'll keep this simple:
   return 'Home';
}

function build_primary_links() {
  // this is also far more complex, but I'll keep this simple as well
  $primary_links = array('Home' => SITE_URL,
                                     'News' => SITE_URL.'/?op=news',
                                    );
  return $primary_links;
}

boogyman broke the code. Without Smarty, it's:

<?php foreach($pages as $page) { ?>
  <a href="<?php echo $page->url ?>"<?php if($page == $this_page) { ?> class="current"<?php } ?>>
    <?php echo $page->title; ?>
  </a>
<?php } ?>

... assuming $pages is an array of "page" objects with "url" and "title" properties. It was mostly example pseudo-code though.

I really do recommend using a templating system for any reasonably-sized sites. PHP's default mix of data, logic, and presentation is a maintainability nightmare.

[matthewmjscott]

This is my array... doesn't appear to be working though:

<?php

define('SITE_URL', 'http://localhost/');

// array(page_title => page_url)

$pages = array('Home' => SITE_URL,
               'News' => SITE_URL.'/news.php',
               'Forum' => SITE_URL.'/forum',
               ); 
?>

[Twey]

I said "objects," not "arrays."

class Page {
  public $title;
  public $url;

  private static $instances = array();

  public static get_current() {
    foreach(self::$instances as $page)
      if($page->url === SITE_URL . $_SERVER['REQUEST_URI'])
        return $page;
    return false;
  }

  public Page($title, $url) {
    $this->title = $title;
    $this->url = $url;
    Page::$instances[] = $this;
  }
}

define('SITE_URL', 'http://localhost/');

$pages = array(
  new Page('Home', SITE_URL),
  new Page('News', SITE_URL . '/news.php'),
  new Page('Forum', SITE_URL . '/forum')
);

$current_page = Page::get_current();

Thanks Twey, but using that I get the following error message:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/bigbro/public_html/matthewmjscott/testingmenu.php on line 95

EDIT: I think the problem is that my server runs PHP4 and not PHP5 but I'm not entirely sure...

[boogyman]

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/bigbro/public_html/matthewmjscott/testingmenu.php on line 95

refers to a missing curly brace.. the error occured on line 95. you are going to need to check all of your open curly braces above that point to figure out which one(s) has not been closed.

[matthewmjscott]

Yeah. There's no missing curly braces, I think it's because I don't have PHP5. Thanks for your help anyway, I will recommend DD to my friends

[boogyman]

the php interpretter doesnt lie; it has nothing to do with which version of php you have installed
if you cannot find the mistake but would like help post your code encapsulated in [code][/code] tags
