I have written some modules to have it look nicely. What I need now is to re-order Joomla's standard viewing of the content. I have looked into com_content, and my first idea was to write my own component for it. But now I realized it would be about 90% a copy of com_content.
The problem is: When you open a link to a section, com_content views a list of the categories. But I want a list of the articles in category News of each viewed, and a link to every article in category Infos on the menu to the left. And of course, view each on click.
Is there a way to achieve that without writing an own component? Or would it be advisable to customise com_content to my needs? I want this done with a minimum of fuss and complexity.
You can override components view-templates in your theme.
In your case, for articles: Articles are part of the content component. components/com_content/views/article/tmpl/default.php is the default view of an article.
To override it copy the file to templates\<yourtheme>\html\com_content\article/default.php.
As an example, see the default theme ja_purity or beez, which also override it.
That way, you will only change the layout and only for your theme. The component will stay in tact and updates will not be as complicated as otherwise.
The visible components on your website are called modules. See the modules section in the admin section. The category-view is one of the default modules. There is also a module to display a list of categories (AFAIK). That is what you want, right? The modules listed in the module section are not all available ones, but all that are created. You can create a new one and set its type to the category-list for example, and define in what block of the theme it should display.
If you want to do your own Module, do so. Code it, then add it in your admin section and you’re done.

Like the topic say I want to overwrite/change the "Menu Manager: Edit Menu item" layout. To illustrate my question:
In the picture whiche is shown I want to change the labels: Layout, Option, Integration.... and add some other options to it. How can I do it? Or is this even possible?
In order to change the text, simply use language overrides, google is your friend.
In order to add functionality, let's first of all explain what we're talking about to ensure we're on the same page.
Joomla components have views which can have one or more layouts, i.e.
/components/com_content/views/category/tmpl/ contains two layouts, blog and default.
A layout can additionally contain an .xml manifest (in our case, blog.xml and default.xml) allowing us to create a menu item for the specific view/layout combination. The .xml file contains the parameters that the user will set, you can add your own as well.
When you want to change Joomla, usually there is a way to do so without touching the core, which would be pretty bad, as any Joomla! updates would break your work.
For the view layouts a special feature called template override was developed, which allows you to create an alternative to the view layout in a safe place (under your template folder, in this case your admin template), and this is the most elegant and effective way to achieve your result.
Beware though, you are just creating a layout, most likely you will want to add functionality, if it's complex you might be better off creating a dedicated component to keep the code clean. Or you can just put all the logic in your view, query the database from there. But in this latter case, get paid, and run away. Never answer the phone to the customer again.
A final alternative is to write a system plugin that will manipulate the page markup after it was generated in the event onAfterRender(). This is a simple and good approach if you only want to add a button or make minor changes, but if you do anything more than that, see the above advise about running away.
I have several pages on my blog that are quite specific and I know exactly what links I would like to appear on the sidebar of each page.
The only way I know how to control sidebar content is to designate certain asides to appear with certain layouts.
In my case, these pages do not each need a unique layout (per-se), they just need a different set of asides. So I am reluctant to create a separate layout for each page just so I can control the asides with more precision.
You are correct, you'll need a new layout in which you can specify specific page_asides. There's a good example of the customizations you'll need to make here: New Plain Page Layout for Octopress
I am willing to create a logic in which If I can fetch only desirable module in a particular position.
As we know that Joomla displays the module on basis of positions given to modules created, hence there could be several modules for a single position.
Now what If I only want a single module from those modules who has the position, say "positon-1".
Thanks
Each module can be told to be shown only on specific pages. Look in the module settings at the "Menu Assignment" part. There you can set it to show on
all pages
No pages
Only on the pages selected
On all pages except those selected
So you can set a module to show on the homepage in position-1, but on all other pages there is a different module shown on the same position.
Don't position names like position-1, although the example templates shipped with Joomla! do so. Use semantic names for the module positions. Then, within your template, you define, where these positions live.
Now what If I only want a single module from those modules who has ... [a certain] position
That will never happen then. You're going to have a position called search where the serach field is located, and maybe another one called navigation, where you publish your navigational menus. You get a lot more positions, but also much more flexibility. So if you have a module that needs its own position as in your question, let's have it that.
there are tutorials on the web about gow to create index.html, css file and template.xml that contain placeholders. ok, i got it, it's simple. but i need a template that has some different views. for example:
-all pages have a topmenu, header, left sidebar, mainarea and a footer but:
-first page has no header .topmenu after which sidebar, mainarea and footer comes.
-second page has sidebar moved from left to right
-third page has four blocks (blocks for special offers) instead of mainarea.
as far as i can see, i need to create three standalone templates with unique set of placeholders for each template. because i can't see the way to change laarge mainarea placeholder with four placeholders for offers blocks on some pages. dynamically.
is there if-statements in joomla templates to simply determine a document id to view four placeholders instead of mainarea. or to not show header on the main page (f.e. doc. id="mainpage")
but i want it to be selectable like:
-this page has first case of that template (index_1.php)
-and that page has a second case of the same template (index_2.php)
like a selectbox.
is that possible?
I will make this an answer as opposed to a comment since I believe it will do what you are looking for.
Once your articles are setup and your links to them are established (the site has the info on it you're looking for), you can create the modules containing the data that you want shown from time to time.
Go to the module manager - on the right you should see 'module assignment' or something along the lines of 'display this module on the following pages'; you can then pick which pages you want the module to show on. You can specify all pages, none, specific pages, however you want.
This will enable you to show them only where needed however you like.
You can ALSO do this programatically inside the module (if you do custom HTML and use an extension like Sourcerer to add PHP to the module) with PHP should you want a little more flexibility, but just choosing the pages to show on should work for what you're doing.
I'll start out by mentioning that there is a developer forum for Zoo and I have used it already. My purpose posting here is that I typically get a thorough answer within minutes or hours at SO, whereas the responses on dev forums can be slow or non-existent due to the smaller population base.
My question regards Yootheme's ZOO 2.3.2. By default, a product "Frontpage" appears to have a "Categories" box rendered on top of the items. If one turns off all the available options in Frontpage/Template configuration (hide Titles, Count, Descriptions, etc.), an empty box still remains on top of the items.
I've been able to manually remove the box in its entirety by addressing the following file:
media/zoo/applications/product/templates/default/frontpage.php, and commenting out lines 84-92:
<!-- <?php
// render categories
if ($this->category->childrenHaveItems()) {
$categoriestitle = $this->application->getParams()->get('content.categories_title');
echo $this->partial('categories', compact('categoriestitle'));
}
?> -->
Seems like there should be a more eloquent way of doing this on the admin backend, but I couldn't find one. Am I missing something or is my solution the best one?
ZOO is designed to easily be able to modify the built in templates to suit your needs. ZOO templates are meant to be overridden much like Joomla uses template overrides. Rather than editing the default template, you simply create a new template that does what you want it to. The default template should not be changed.
Here is the documentation on ZOO templates - http://www.yootheme.com/docs/home/item/create-a-new-template
Rather than edit the file you mention above, you make a new template here -
media/zoo/applications/product/templates/YOUR-TEMPLATE-NAME/frontpage.php
Then do all the changing you want without messing up the default.
There is an easier way: First, you must identify what calls the item called "frontpage". In PURE yootheme at least it is called from "home" in the "mainmenu". So click "home" buton of the mainmenu, then over the right menu "Parameters(Basic)" you just chose "-select aplication-" instead "frontpage" and that's it.The Frontpage and its "box" are now gone. At least it works for me.
