How do I edit the layout for a category page, such as the they use on: http://gwpvx.gamepedia.com/Category:Meta_working_PvP_builds

I would like to add html code at the exact same where they have the ad but on my own wiki. This code should only be visible in categories.
There is no simple, built in way to alter the category pages. Adding the ad with Javascript from MediaWiki:Common.js would probably be easiest for you.
That said, if you really need to alter the HTML code of the page, the hook CategoryPageView is what you are looking for.
Something like this:
$wgHooks['CategoryPageView'][] = 'insertAdInCategoryPage';
public static function insertAdInCategoryPage( &$categoryArticle ) {
global $wgOut;
$wgOut->addHTML(/*some HTML*/);
return true;
}
$categoryArticle will be a article object.

Hello guys I'm new to MediaWiki and trying to build my own extension. Using this extension I'm trying to show some content blow page heading but only to a page specific to a category.
For that, I'm using two hooks:
onArticleViewHeader ( To add my HTML content below the page heading)
onOutputPageMakeCategoryLinks (To get all the category of page being loaded)
From the first hook, I'm able to show my content using the following code:
public static function onArticleViewHeader( &$article, &$outputDone, &$pcache ) {
$article->getContext()->getOutput()->addHTML("Printed from a hook");
}
The above code prints the HTML below every page heading but I want to load HTML only to a specific page category. So for that, I'm trying to load the category and I'm just trying to call my first hook only if the category gets caught.
public static function onOutputPageMakeCategoryLinks( &$out, $categories, &$links ) {
foreach($categories as $category){
if($category=="my_page_category"){
MyExtentionClass::onArticleViewHeader();
}
}
}
I know I'm calling the hook in a bad manner which is not correct. But I just wanted to call my 1st hook 'onArticleViewHeader' from inside of my 2nd hook so that I can print my HTML only to a page with a specific category.
Just use $article->getPage()->getCategories() in the header hook.
Haven't really got the exact solution of the question I asked but has got the way out to solve the problem I have been facing.
I just tried getting the current categories in the "onArticleViewHeader" itself by using some of MediaWiki's global variables.
global $wgOut;
$title = Title::newFromText( $wgOut->getPageTitle() );
$categories = $title->getParentCategories();
if(isset($categories['Category:my_cat_name']){
//formed my logic here
}
This might help some other people facing this kind of issue.
I have a page set up as a disambiguation page inside of Category:Disambiguations that looks like this:
'''Sword''' may refer to one of the following:
* {{Link|Item|Blue Sword}}
* {{Link|Item|Yellow Sword}}
* {{Link|Item|Green Sword}}
Is there a way I can use the '#ask' function to get all of the links on that page? This page has no properties on it...
Thanks,
You could redefine the {{Link}} template to include [[Links to::{{{2}}}]] and declare Property:Links to of the type page. Then you will be able to query the links with {{#show:Sword|Links to}} or {{#ask:[[-Links to::Sword]]}}.
I have a template html page(say Index page) containing a header and three other pages and i want that Header on first two pages but not on third page .Using angularjs routing I am able to have that header on all three pages but cant hide that header from the third page.The pages have different controllers as well .Can anybody help me how to achieve this.
This is not a good practice, not at all! But as your question lacks of code...
You say "The pages have different controllers", so let's say you have PageOneCtrl, PageTwoCtrl and PageThreeCtrl.
If you want to show the header on the page with controllers, let's say: PageOneCtrl and PageTwoCtrl, set a $scope (remember you have to define $scope on that controller first) variable just like:
$scope.showHeader = true;
And in PageThreeCtrl (where you want to HIDE the header element) write
$scope.showHeader = false;
Then in the html you should write:
<header ng-if="showHeader">This is your header content</header>
the ng-if will do the trick, check angularjs documentation for more information: https://docs.angularjs.org/api/ng/directive/ngIf
Doesn't work? Try $rootScope instead of $scope, but watch out! If you use $rootScope then you should declare that variable on every controller.
This is not a good practice, not at all! But as your question lacks of code...
A better practice, and one of the bests in my opinion, would be to use angular-ui-router and set a data attribute to the state (route) with something like
.state('myRoute', {
templateUrl: 'views/my-route-view.html',
controller: 'MyrouteCtrl',
data: {
hideHeader: true;
}
})
, in a .run() function set something like $rootScope.$state = $state (read more about it in the ui.router docs) and then simply: <header ng-if="!$state.current.data.hideHeader">. But I believe you're not an advanced developer to do it :) So keep learning.
Introduce the Problem
I would like to profoundly modify the layout of the Orchard CMS Tags list.
Here is an example page with Shape Tracing enabled.
The only alternate that it suggests for the List shape is ~/Themes/TheThemeMachine/Views/List.cshtml, because the page is rendering the default List shape. I would like to have other alternates that are specific to the page.
After reading Orchard list customization, I have been able to implement the default List.cshtml in razor. What I would like to do, though, is to add another alternate, such as ~/Themes/TheThemeMachine/Views/Parts.Tags.List.cshtml instead of implementing the default List.cshtml template.
The problem seems to be that the page is rendering the generic List shape.
In contrast, the blog post list page is rendering a Parts_Blogs_BlogPost_List shape, which means that a ~/Themes/TheThemeMachine/Views/Parts.Blogs.BlogPost.List.cshtml is available.
Search and Research
All quotes below are from the Orchard list customization blog post, which explains how to add a list item alternate (whereas I would like to add a list alternate).
What we really want is an alternate template... aptly called Shape
Alternates... [so] enable Shape Tracing... and select a post in the list...
[you will see that] we already have some possible alternates.
My example page also has some possible alternates for the List Content. Cool.
we need to somehow get into list rendering... [t]he default is defined
in code... [which] can be override by a new [cshtml] template in our
theme.
Okay. That makes sense. We can override the list rendering.
As Shape Tracing can show, we can override the list rendering for a
blog by creating a Parts.Blog.BlogPost.List.cshtml template.
This works for alog but not for the blog Tag page (example page). You see, the blog displays a **Parts_Blogs_BlogPost_List shape and suggests an appropriate alternate but the blog tags page displays the default List shape with no alternates other than List.cshtml.
Blog Page with alternates galore
Blog Tags Page with one alternate List.cshtml
So, I created a List.cshtml not a Parts.Blog.BlogPost.List.cshtml template, and save it in my theme's Views directory. (One problem here is that, once we get it working, we will b overriding the default List rendering.)
Then I add the Razor code (copy and pasted from Bertrand's post) to override the default rendering for Lists. When I refresh the site, the browser renders a blank page. It isn't working. Here's the code:
This Does NOT Work in List.cshtml
#using Orchard.DisplayManagement.Shapes;
#{
var list = Model.ContentItems;
var items = list.Items;
var count = items.Count;
var listTag = Tag(list, "ul");
listTag.AddCssClass("content-items");
listTag.AddCssClass("blog-posts");
var index = 0;
}
#listTag.StartElement
#foreach (var item in items) {
var itemTag = Tag(item, "li");
if (index == 0) {
itemTag.AddCssClass("first");
}
else if (index == count - 1) {
itemTag.AddCssClass("last");
}
#itemTag.StartElement
#Display(item)
#itemTag.EndElement
++index;
}
#listTag.EndElement
As a trouble shooting step, I replace the List.cshtml with <p>Hello world.</p>. Orchard renders the markup as expected. So, something is incompatible between the Razor code from Bertrand's blog and the Tags List.
To find out what exactly is incompatible, I try Betrand's code one line at time to see where it breaks (yup, VS would be better than WM here). At each change, I restart WebMatrix and view the results. This is the minimal code that breaks it.
The Culprit
#using Orchard.DisplayManagement.Shapes;
#{
var list = Model.ContentItems;
var items = list.Items;
}
list.Items isn't appropriate here. So I comment it out again and run the <p>Hello World</p> version again. Also, Shape Tracing reveals that on my Tags/tagname page, the Content Zone is now rendering the List twice. Is that normal?
As another step, I replace Model.ContentItems just with Model. It works. It seems that, to override the List.cshtml template, we cannot use the ContentItems property of Model. Here is the new, working code:
This Does Work in List.cshtml
#using Orchard.DisplayManagement.Shapes;
#{
//var list = Model.ContentItems;
//var items = list.Items;
var items = Model.Items;
var count = items.Count;
//var listTag = Tag(list, "ul");
var listTag = Tag(Model, "ul");
listTag.AddCssClass("content-items");
listTag.AddCssClass("blog-posts");
var index = 0;
}
#listTag.StartElement
#foreach (var item in items) {
var itemTag = Tag(item, "li");
if (index == 0) {
itemTag.AddCssClass("first");
}
else if (index == count - 1) {
itemTag.AddCssClass("last");
}
#itemTag.StartElement
#Display(item)
#itemTag.EndElement
++index;
}
#listTag.EndElement
Onward through the article.
So far so good, we have effectively taken over the rendering of the
list, but the actual HTML [will] be... identical to what we had before
[except for] the implementation.
Okay. I'm following. We want to modify the rendering not just re-implement it.
Alternates are a collection of strings that describe additional shape
names for the current shape... in the Metadata.Alternates property of any shape.
Gotcha. Now, why doesn't the Tags/tagname page show an alternate other than just List.cshtml for the rendering of the List shape?
All we need to do is add to this list [of alternates]... [and make sure] to respect the lifecycle...
Great. Maybe we can we add another alternate for the List shape on the Tags/tagname page. But, doing that is different from what Betrand is explaining. While Betrand's blog post is excellent, it is explaining how to add an alternate for an item, whereas I would like to add an alternate for the list.
The List.cshtml template is where I would add an alternate for a List Item as follows:
ShapeMetadata metadata = item.Metadata;
string alternate = metadata.Type + "_" +
metadata.DisplayType + "__" +
item.ContentItem.ContentType +
"_First";
metadata.OnDisplaying(ctx => {
metadata.Alternates.Add(alternate);
});
So that...
[t]he list of alternates from Shape Tracing now contains a new item.
Where and how, though, would I add an alternate for the List shape? Bertrand has recommended to check out the Shape Table Providers blog post for this. The quotes below are from that post.
But what if you want to change another shape template for specific
pages, for example the main Content shape on the home page?
This looks like a fit, because my example is the main List shape on the tags page. To do this we...
... handle an event that is triggered every time a shape named "Content"
[in our case "List"] is about to be displayed. [It] is implemented in a shape table provider which is where you do all shape related site-wide operations.
Great! Here is my implementation for adding another template for the main List shape.
TheThemeMachine > ListShapeProvider.cs
namespace Themes.TheThemeMachine
{
using Orchard.DisplayManagement.Descriptors;
public class ListShapeProvider : IShapeTableProvider
{
public void Discover(ShapeTableBuilder builder)
{
System.Diagnostics.Debugger.Break(); // break not hit
builder.Describe("List").OnDisplaying(displaying => {
// do stuff to the shape
displaying.ShapeMetadata.Alternates.Add("Tags__List");
});
}
}
}
The above builds and runs but does not hit the breakpoint nor add an alternate for the List shape on the /tags page. So I looked into the Orchard.Azure.MediaServices module and its CloudVideoPlayerShape which implements IShapeTableProvider. Its breakpoint does get hit. How is my code for ListShapeProvider fundamentally different than the code for the CloudVideoPlayerShape?
Also, I installed the Orchard.Themes.CustomLayoutMachine.1.0.nupkg as suggested in Bertrand's blog post. It unfortunately no longer contains an implementation of IShapeTableProvider.
I have also looked at this szmyd post, which does not explain where to put the IShapeTableProvider code.
Further, I installed the Contoso theme from the Orchard Gallery. It works and builds after adding a reference to Microsoft.CSharp. It also includes an implementation of the IShapeTableProvider. Hooray! Comparing its ContentShapeProvider with my ListShapeProvider reveals a subtle but important difference:
Contoso.csproj
<ItemGroup>
<Compile Include="Code\ContentShapeProvider.cs" />
</ItemGroup>
My implementation didn't include the .cs file in the compilation, because my theme has neither a .csproj nor a App_Code folder. So, I recreated my theme with the following code generation:
orchard.exe
feature enable Orchard.CodeGeneration
codegen theme My.FirstTheme /CreateProject:true
theme enable My.FirstTheme
feature enable Orchard.DesignerTools
When adding the ListShapeProvider.cs file, Visual Studio automatically added a ItemGroup/Compile entry for the file, which included the code in compilation. Hooray!
These two posts will help.
Shape Shifting
List Customization
Here are steps of my own minimum solution.
Download and unzip Orchard.Source.1.8.zip.
Open "\Downloads\Orchard.Source.1.8\src\Orchard.sln" in Visual Studio.
Build the solution to create orchard.exe.
Generate a new theme with orchard.exe. Use CreateProject:true because you will need a csproj to include your .cs file.
orchard.exe
setup /SiteName:SITE /AdminUsername:ME /AdminPassword:PWD /DatabaseProvider:SqlCe
feature enable Orchard.CodeGeneration
codegen theme My.FirstTheme /CreateProject:true
theme enable My.FirstTheme
In VS, add a ListShapeProvier.cs file to the root (or any folder) in your theme.
Add the following code to ListShapeProvider.cs.
namespace My.FirstTheme
{
using Orchard.DisplayManagement.Descriptors;
public class ListShapeProvider : IShapeTableProvider
{
public void Discover(ShapeTableBuilder builder)
{
System.Diagnostics.Debugger.Break();
// implementation here
}
}
}
Build the solution.
Run Orchard.Web.
Visual Studio will break at System.Diagnostics.Debugger.Break(). If it doesn't, go to the Orchard Dashboard and make My.FirstTheme the Current Theme.
Now read Shape Shifting to implement public void Discover(ShapeTableBuilder builder).

I´m evaluating GWT as one of the alternatives to develop AJAX applications for my future projects. Untill now it is as good as it gets, but now I´m stuck looking for a way to capture a click on a tag inside HTML widget. I want to write links inside the HTML but I want to process the clicks in my application, withou reloading the page. Imagine I have the following HTML:
<p>GWT is a great tool and I think it will be my preferred tool to develop web applications. To check out my samples <a id='mylink'>click here</a></p>
I want to capture the click over the "click here" part of the text. What I´ve done so far is to try to attach the id "mylink" to some sort of clickable widget and process the click with a ClickHandler for that widget, but nothing is working.
Is there a way to do that? By the way, I know very little about Javascript.
Thank you in advance.
You can also do it like this:
Anchor.wrap(DOM.getElementById("mylink")).addClickHandler(yourClickHandler);
DOM class is com.google.gwt.user.client.DOM.
Edit after comments.
OK, the method works for elements out of GWT widgets (element comes with HTML file). If you need to generate it in GWT code then you can add link element separately. But it won't work if your content goes for instance from DB.
HTMLPanel html = new HTMLPanel("GWT is a great tool and I think it will be my preferred tool to develop web applications. To check out my samples ");`
Anchor a = new Anchor("click here");
a.addClickHandler(yourClickHandler);
html.add(a);
If it is fully dynamic I don't have an idea at this point. I was trying with HTML() widget, where you can plug your click handler, but I couldn't find a right way to determine whether the click was in A element. Strange.
The final approach (I hope)
This one should work finally. And I think this is the way it should be done, especially that it allows any structure of the HTML. The are two ways:
1. Convert links within HTMLPanel
This one will find all A elements and convert them into Anchors. It ignores href attribute, but you can add it easily :)
HTMLPanel html = new HTMLPanel("<p>Multilink example 2: <a>link1</a> and <a>link2</a></p>");
NodeList<Element> anchors = html.getElement().getElementsByTagName("a");
for ( int i = 0 ; i < anchors.getLength() ; i++ ) {
Element a = anchors.getItem(i);
Anchor link = new Anchor(a.getInnerHTML());
link.addClickHandler(...);
html.addAndReplaceElement(link, a);
}
2. Insert links into prepared spots
Just insert placeholders, where the widgets should be inserted. You could also use the addAndReplaceElement() method but with string ID.
Anchor a1 = new Anchor("a1");
a1.addClickHandler(...);
Anchor a2 = new Anchor("a2");
a2.addClickHandler(...);
HTMLPanel html = new HTMLPanel("<p>Multilink example: <span id='a1'></span> and <span id='a2'></span></p>");
html.add(a1, "a1");
html.add(a2, "a2");
Try something like this.
For your web page, you can use UiBinder:
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<g:HTMLPanel ui:field="panel">
<p>
GWT is a great tool and I think it will be my preferred tool to
develop web applications. To check out my samples
<g:Anchor ui:field="myLink" text="click here" />
</p>
</g:HTMLPanel>
</ui:UiBinder>
Notice that I've replaced your tag with an Anchor widget. There is also a Hyperlink widget, which has hooks into the history system.
The Anchor has a id of "myLink", which is used in the GWT companion to the XML file:
public class So extends Composite {
private static SoUiBinder uiBinder = GWT.create(SoUiBinder.class);
interface SoUiBinder extends UiBinder<Widget, So> {
}
#UiField
Anchor myLink;
public So() {
initWidget(uiBinder.createAndBindUi(this));
myLink.addClickHandler(new ClickHandler() {
#Override
public void onClick(ClickEvent event) {
GWT.log("caught the click");
}
});
}
}
I've added a ClickHandler that captures and acts on the click event.
The main program is simple:
public class SOverflow implements EntryPoint {
public void onModuleLoad() {
RootLayoutPanel.get().add(new So());
}
}
Run this after and a webpage appears with the text and hyperlink. Click on it and "caught the click" appears in the console window (I'm using Eclipse).
I hope this is what you're after. If not exactly, it might at least give you some ideas of how to attack your problem.
