Joomla 3 Overwrite/Change "Menu Manager: Edit Menu Item" - joomla

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.

Comic navigation in joomla?

I have a joomla site and would like to integrate some old unfinished webcomics to it, so I can pick them up where I stopped in a CMS that won't leave me in an absolute frothing rage (thanks, wordpress).
I've got some experience with Joomla and I believe it would be a pretty good platform for managing multiple comics... except for the small issue of horrid navigation between pages/articles. Joomla's integrated article navigation is a humble but passable start, but if you intend to use categories to organize chapters then getting from the end of one to the beginning of the next is... yeah. This is a pity, as Joomla's category and article management options are beautiful for archiving and presentation, and adding gantry 5 to it means a great deal of control over the reading experience. Basically, joomla has pretty much everything I want, except for the navigation.
Ideally, what I'd like to be able to accomplish for comic navigation in joomla is:
Clickable full-article-image leading to next article/page
Prev/next article buttons (already available)
Prev/next category buttons (do we have those?)
The latter two in a module I can choose where to publish (optional)
And this is it, basically. I understand that implementing the first could be very hard without some major template customization, in which case I'd be willing to insert the image as a link in the article body... but only if there was one single code I could use, like the one that generates the next category article button. Because I'm not willing to create hundreds of menu items to generate links page-by-page.
So is any of this doable?
This is a quick answer but too much for a comment. I'm assuming since you are on SO that you don't mind coding (as opposed to just configuring).
I think you need to do two things. First you need to create a pagination.php for your template. This will let you really super control what the pagination looks like. You can have images, special css and js, whatever you want. You can also add the "last" and "first" options.
I think you need to make a new plugin to replace the core pagenavigation plugin and that also generates the previous/next category links. (Or I guess you could make one just to do categorynavigation depending on what you want.) HOWEVER, it seems to me that there is data on the sibling links that is already being generated in the content category model so you might be able to use that. (Check the code; I think there was never a UI for it, but it is there. Even if it isn't there, siblings are very easy to obtain in nested sets)
The other thing you can really think about if you go that route is changing the whole thing somewhat to use a module that gets the current ID and category ID from JInput. You might also be able to use JPagination. The important thing, however is that you make sure to do the caching the way the pagination that is there does it. In other words you really want to cache the whole list in the order you want so you are not running so many queries and slowing your site down. You may want to look at the categories and category modules to get some ideas about the queries to do.
Hope that gets you started, but it is definitely something you can do without too much trouble.

Joomla 3 Article alternative layout

I've created an alternative layout for one of my articles which can be applied successfully, but as has been highlighted in various forums: if you view the article using the Single Article menu type the alternative layout doesn't get applied because of an XML override.
I have a Joomla site that is setup for Sales and Support where the article info such as date, hits etc is useful but on the marketing side none of that is needed, hence an alternative layout would work well.
I want to know how to enable my alternative layout using the Single Article menu type - I've already got the layout how I want it (testing it by having it overwrite default.php) but want to set it up as marketing.php instead and only have it applied to what is needed.
You're probably not going to like this answer because you have already written you're alternate view. If you were rewriting it to begin with, why would you not write in a way that the side bar parameters (date, hits, ect) are within a container that is only loaded conditionally. This way you would only have one view to worry about and a lot less headaches.

Custom section/category viewing in Joomla

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.

changing navigation in magento dynamically

I want to know that can i change the navigation menu dynamically,i am having two tabs on the basis of which i want to render the navigation menu.How can it be done
Thanks in advance
For usability reasons, the global navigation generally shouldn't change. Users will expect to see the same options available to them and will get confused (and leave) if they aren't.
Could you explain the requirement more?
EDIT:
Usability issues aside, try adding all necessary items to the top nav, then use Javascript to toggle between tabs. If you don't want to change the navigation PHTML files to add IDs to them, you can use the existing classes to target which nav items to show and which to hide.
Since Magento stores cannot function without JS anyway, you should be pretty safe with that solution. Preferably, you can change the top nav's template (I believe app/design/frontend/base/default/template/page/template/links.phtml in 1.4) to use IDs for those LIs as well, in which case you can target those instead.
Thanks,

Magento - adding a new field to the product options in admin

I'd like to add a new tab to the 'catalog->manage products->product information' page in the admin. Underneath the 'images' tab, I'd like to add a new tab for video, with a simple text input for adding a video url, which I can then grab for the frontend.
Anyone any ideas where the files are that I need to edit? I've been looking for the last couple hours with no joy. I found the list of current options in Mage_Catalog_Model_Resource_Eav_Mysql4_Setup but can't figure out how to add to them...
Seems it gets some from Mage_Adminhtml_Block_Catalog_Product_Edit_Tabs. If I copy one of the tab sections here and change the title to Video, I can get it to display in the tabs on the left. But how do I then add the options for it?
What you are trying to do, from the sounds of it, is to create a custom field and add it to your catalog data. The good news is that you don't need to muck around in the PHP for that.
Head to Catalog -> Attributes -> Manage Attributes and create a new attribute for yourself called "Video URL" (or something to that effect). This will probably be a text field, and you may want to hide it from comparison on the frontend of the site (select "No" for all those boxes at the bottom of the form).
Once you've created an attribute, you will need to add it to an attribute set. If all your products are of one "type", and if you didn't create any other attribute sets, this should be only one step. Head to Catalog -> Attributes -> Manage Attribute Sets and create a "New Group" called "Video" and drag your new video url attribute into it. Save the attribute set and you should now have your new tab.
The only complication from what I read in your post could be positioning it underneath the images tab. Magento adds several tabs statically (the long way, in the PHP) and doesn't generally obey ordering of the tab groups. Consider the time tradeoff.
Hope that helps. Thanks,
Joe
Per your other comments, for the URLs a simple attribute would work but files would tend to be more difficult. To add a custom tab, as you said, you can edit (or in the case of a plugin, override) Mage_Adminhtml_Block_Catalog_Product_Edit_Tabs::_prepareLayout and add your tab. You'll need to add a block or template to display your tab contents.
After that, you'll need to store the data somewhere. Looking in Adminhtml/controllers/ProductController, you should be able to hook into the catalog_product_prepare_save event to get data from $event->getRequest() and push it onto the product or save another entity as necessary.
I'm not sure how well file saving semantics would work on a product, so you may want to do your own data storage in the extension and then provide something like a getVideoForProduct method to retrieve it.
Then the only thing left to do is modify the catalog/product/view.phtml template file to include your thumbs and create a controller in your extension to provide a modal w/ the video (or do it in JS).
I know that's a bit of a general answer, but it's the rough path you would need to take for tabs. Let me know if any specific part of that is unclear.
Thanks,
Joe
