POBuilding breadcrumbs in Symfony2
text
Body
copied!<p>I'm creating a website and have successfully got my navigation Menu working using a tree structure stored in a database.</p> <p>A <code>Menu</code> object as a <code>active</code> property, but I don't know how to go about setting it to active! If I can do that, then I can get the path of the currently active <code>Menu</code> and render the breadcrumbs using WhiteOctober's BreadcrumbsBundle or something similar. </p> <p>I've read tons of questions on SO, and also looked at the different bundles available, but I'm still stuck on how to do this.</p> <p>How would I go about finding out menu item to set as active?</p> <p>EDIT:</p> <ul> <li>Menu class: <a href="https://gist.github.com/robcaw/c76426957ea6f262d217#file-gistfile1-php" rel="nofollow">https://gist.github.com/robcaw/c76426957ea6f262d217#file-gistfile1-php</a> </li> <li>Menu controller: <a href="https://gist.github.com/robcaw/af18e7c0e61f109e9bda#file-gistfile1-php" rel="nofollow">https://gist.github.com/robcaw/af18e7c0e61f109e9bda#file-gistfile1-php</a></li> </ul> <p>EDIT 2:</p> <p>Ok, I've almost done it. I've managed to compare the current path, using <code>$this->container->get('request')->getPathInfo();</code> to a <code>Menu</code>'s set <code>url</code>. </p> <p>To do this I needed to flatten the menu tree structure into an array. As I'm using the DoctrineExtensions' Tree extension, I used its repository's <code>getChildren($node)</code> to do this. So now iterating over the array is easy and can compare the url and path.</p> <p>In the breadcrumb controller, I can pass the <code>$current_item</code> from the menu controller, and again use the Tree repository and its <code>getPath()</code> method which recursively gets parents of the given node.</p> <p>However, there is still a problem, as some pages on the website don't have a menu entry. So for example if I visit <code>site.com/news/tags/stuff</code>, there is no menu entry for it and so breaks the site.</p> <p>So far: </p> <ul> <li>MenuController: <a href="https://gist.github.com/robcaw/61383e26d0a7637bb3f1#file-gistfile1-php" rel="nofollow">https://gist.github.com/robcaw/61383e26d0a7637bb3f1#file-gistfile1-php</a></li> <li>BreadcrumbController: <a href="https://gist.github.com/robcaw/62341672db576fcb2864#file-gistfile1-txt" rel="nofollow">https://gist.github.com/robcaw/62341672db576fcb2864#file-gistfile1-txt</a></li> </ul>
