I´m trying to create a sitemap of all children of the sitetree. For some pages ShowInMenus is set to false. But still these pages should be shown in the sitemao. I know you can loop over all children of a page like this (ignoring ShowInMenus):
<% loop AllChildren %>
$Title
<% end_loop %>
Can I do something similar on the top Level of the sitetree?
Thx,
Florian
i do not know any build in loop you can use for this but you can do in php
public function AllPagesWithParentIDZero() {
return SiteTree::get()->filter('ParentID', 0);
}
and use in template
<% loop $AllPagesWithParentIDZero %>
$Title
<% end_loop %>

Sorry I'm kinda new to Silverstripe.
Is there a way to add a active/current class to the BlogTagsWidget.ss list items?
Cheers
Assuming that the BlogController is the current controller when BlogTagsWidget.ss is rendered, you may be able to use this method directly to check it in the template, e.g.
<% loop $Tags %>
<% if $CurrentTag && $CurrentTag.ID == $ID %>
Current
<% else %>
Not current
<% end_if %>
<% end_loop %>
If it's not available then you may need to add some extra code to provide the current tag boolean in BlogTagsWidget::getTags().
In Docpad, the following code (using a Query-Engine helper and eco) pulls a list of file names from a directory tree and addds their url to an array:
<% images = []; %>
<% for file in #getFilesAtPath({relativeOutDirPath: 'images/'}).toJSON() : %>
<% images.push(file.url) %>
<% end %>
How might I limit the query to a subset of files, say only PNGs?
So like stated in my answer to your other question: What methods can be called on Docpad's Query tools?
Object returned by your query has some additional default metadata you can't see. As you can see here http://docpad.org/docs/meta-data, one of the metadata is "extension". So you can query with condition like:
extension:'png'
So your code might look like (notice findAll part that gives you a possibility to set search condidtions):
<% images = []; %>
<% for file in #getFilesAtPath({relativeOutDirPath: 'images/'}).findAll(extension:'png').toJSON() : %>
<% images.push(file.url) %>
<% end %>
Or if you want to return all files and trigger different actions on different extensions you could:
<% images = []; %>
<% for file in #getFilesAtPath(relativeOutDirPath: 'images/').toJSON() : %>
<% if file.extension is 'png' : %>
<% images.push(file.url) %>
<% end %>
<% end %>
I have following problem:
Some links that show up in the Menu (the children of "Portfolio") are links to custom controllers. Of course now the LinkingMode is not available for that Links. Thats a image of the Menu:
So the children of Portfolio (Website, Application, etc.) are actually Category-DataObjects, which do not have a SiteTree Representation. The Submenu of Portfolio is created via checking and looping for all found categories in the Database.
The menu creation looks like that:
<ul>
<% loop Menu(1) %>
<li class="$LinkingMode">
[$LinkingMode] $MenuTitle.XML
<% if Children %>
<ul class="secondary">
<% if ClassName == 'ProjectsPage' %>
<% loop $Top.Categories %> <!-- loop all found categories, every found item links to the custom category controller -->
<li class="$LinkingMode">$Name</li>
<% end_loop %>
<% else %>
<% loop Children %>
<li class="$LinkingMode"><span class="text">$MenuTitle.XML</span></li>
<% end_loop %>
<% end_if %>
</ul>
<% end_if %>
</li>
<% end_loop %>
</ul>
Every Category (Website, Mobile) in the Menu links to a custom controller, which looks basically like that:
class Category_Controller extends Page_Controller {
public function show($arguments) {
return $this; //there will be more code to display all projects of a category
}
}
I expect that I have to add some custom code for the Category_Controller which tells the Portfolio Page which linkingmode it has...
Many thx,
Florian
I´ve found good tips here:
http://www.ssbits.com/snippets/2009/extending-linkingmode-to-handle-controller-actions/
http://www.ssbits.com/tutorials/2010/dataobjects-as-pages-part-1-keeping-it-simple/
Thats the Category_Controller.php (a public var CategoryID is set there):
class Category_Controller extends Page_Controller {
public $CategoryID;
public function index($arguments) {
$slug = $arguments->param("Slug");
$category = Category::get()->filter(array('Slug' => $slug))->First();
$this->CategoryID = $category->ID;
}
}
DataObject Category (LinkingMode function checks if the current CategoryID set in the Controller equals the ID of the Category DateObject):
class Category extends DataObject {
public function LinkingMode(){
$categoryID = Controller::curr()->CategoryID;
return ($categoryID == $this->ID) ? 'current' : 'link';
}
}
In the template you can check then the linking mode as usual:
<% loop $Categories %>
<li class="$LinkingMode">$Name</li>
<% end_loop %>

I am arranging a dynamic table of textboxes using a loop.
Please review the following code segment in view -
<% foreach (var item in Model.Names) { %>
<% =Html.TextBoxFor(item.Name)%>
<% } %>
The problem here is that i want their unique ids to be generated so that i could access each textbox using JS.
Any help is highly appreciated.
Regards
Irfan
Do this instead:
<div class="editor-field">
<% for (int i = 0; i < Model.Names.Count; i++) { %>
<%: Html.TextBoxFor(m => m.Names[i].Name) %>
<% } %>
</div>
I am trying to create divs dynamically in a view page of an asp.net mvc project. This is the pseudo code:
<%
foreach (element in Model)
{
create the html div element with Div.id = Model.id
}
%>
I looked in the system.web.mvc.htmlhelper object. It provides support for a lot of html elements but not a div. Any Hints ?
There is no such helper for div. But, you can create your own HTML helper for it.
or simply you can go ahead and create divs in view page as
<%
foreach (element in Model)
{
%>
<div id="<%:element.id%>">
.. some html..
</div>
<%}
%>
