Time for action – creating an intro text

In the articles you created in earlier chapters, you've already seen it's good to add a separate intro text to an article Now you know why; if you don't, the article can only be displayed fully on overview pages such as the section overview you just saw Let's fix things by adding

an intro text to our new article

1. Navigate to Content | Article Manager and open the article that you just created (Just What are Ugly Paintings?) to edit it.

2. In the text editor screen, add a new first line In this example, we've entered

The Characteristics of True Ugliness: how do you recognize them?

3. Place the cursor just after this first line to indicate that you want Joomla! to split the article here, and create a Read More link to point to the full article, click on the

Read More button at the bottom of the editor screen A red dotted line appears:

4. In the Parameters (Advanced) panel, set Intro Text to Hide This means the

intro text (in this case the short teaser text we just created) will be hidden

when the full article is shown It will be shown on overview pages

5. Click on Apply and then click on Preview to see the output on the frontend You'll be taken to the frontend home page In the Main Menu, click on the Ugly Paintings link.

Mission accomplished! Now, only the intro text and Read more link of the new article appear

on the section overview page:

More teaser texts will be added to the overview when you add more articles to the section The full five paragraph article is shown (without the teaser text) when the visitor clicks on

the Read more link:

What just happened?

In principle, any article in Joomla! can consist of one continuous text Especially when writing short articles (think of blog posts), one lump of text can suffice But in many cases you'll want

to split articles into an introductory text (a teaser text, in newspaper terms) and the actual article body text, allowing Joomla! to publish the two parts on separate pages

Creating multi-page articles

Suppose you have a long article with several subheadings, each covering various sub-topics that all have something to do with each other Sometimes, you may find such an article is too long It doesn't fit the content screen, you don't want the visitor to have to scroll all that much

There's a tedious solution to this It involves manually splitting the article by creating several individual short articles But luckily, there's also a quick way out By adding page breaks in

a single article, Joomla! will display this single article in the frontend as a series of separate pages, automatically adding navigation links and a table of contents

Time for action – using page breaks to split up an article

Let's say your client doesn't like the one page article on ugly paintings Instead of having one article with several subheadings, they'd rather see some short pages that explain things step

by step To do this, we'll edit the existing article:

1. Navigate to Content | Article Manager and open the Just What is Ugly Art? article

to edit it

2. Select the page break locations This is where Joomla! will split the article into separate pages In this example, we'll replace every subheading by a page break

Select the first subheading (Abstract Chaos) and delete it Now click on the Page

Break button at the bottom of the editor screen A pop-up screen shows:

3 In the pop-up screen, enter the Page Title and Table of Contents Alias.

‰ Page Title: Enter a title for the new page It will be displayed next

to the article title, separated by a dash:

Just What are Ugly Paintings? – Abstract Chaos.

‰ Table of Contents Alias: This is the link text that will appear in the

Table of Contents of the multi-page article The Alias and the Page Title can be the same, however, it's best to keep the Alias text as short as possible

4. Click on Insert Page Break The pop-up screen closes and a grey dotted

line is inserted to indicate the location of the page break

5. Repeat Steps 2 to 4 for each page break required and save the article

Click on Preview to have a look at the frontend results In the frontend

Main Menu, click on Ugly Paintings and locate the intro text of the

Just what is Ugly Art? article Click on the Read More link.

Now, instead of one article Joomla! has created a series of interlinked article pages The

first page the visitor sees is the first (sub) page Pages include << Prev – Next >> links to the

previous and next page; the Table of Content's Aliases you've entered when creating page

breaks now show up as hyperlinks in the Article Index (a table of contents featured on every

sub page):

What just happened?

Joomla! lets you add page breaks to spread the content of a single article over multiple pages To allow the visitor to move back and forth, a Table of Contents section and

Previous and Next navigation is automatically added to multi-page articles

Use it wisely

Working with page breaks gives you an extra level of content below the article level You shouldn't, however, overuse this feature Usually, visitors don't like clicking multiple links

to read an article It's best to reserve multi-page navigation for articles that easily break into logical chunks, such as step-by-step tutorials or portfolio pages showing different clients and projects

Alternative page display techniques: Tabs and accordions

There are many creative ways to put a lot of content on a single page,

without displaying it all simultaneously One of these is using tabs Initially

the visitor only sees the contents of the first tab panel When they click on

another tab, the corresponding content panel becomes visible instead

Another commonly used trick is called the accordion This allows you to

provide multiple content panels and display them one at a time Panels slide out and slide in on a mouse click

You can create both tabbed pages and accordions using Joomla! extensions

In Chapter 10 you'll learn how to install and apply them

Tweaking the details: Changing article settings

When editing an article, you can set a wide array of parameters These allow you to control exactly which article details are shown, when the article will be published, and so on It's a good idea to explore the options to make sure what combination of setting fits your needs best The following is an overview of the settings you can choose per article:

Parameters (Article)

Author, Author Alias The default Author name is Administrator If you want another

name to appear with the article, you can enter an Alias This name will appear as the author name (provided that the Author name is

set to show in the Parameters (Advanced)).

Access Level This setting is important if you want to control if pages are accessible

only to registered visitors See Chapter 9 on user management

Created Date Change this value to manipulate the Created Date that Joomla!

can display with any article By changing the date, you can bring

an existing article to the attention of the visitor because it will reappear in pages with new items

Start Publishing, Finish

Publishing

Sometimes, you'll have prepared content that should only

be published for a given period of time; think of a temporary

promotion, or a special New Years message Use Start Publishing to

enter the date when the new page should appear on the site; set a

date in the Finish Publishing box to automatically unpublish content

after a certain period

Trang 7

[ 153 ]

Parameters (Advanced)

Show Title, Intro Text,

Section Name, Category

Title, Article Rating, Author

Name, Created Date and

Time, Modified Date and

Time, PDF Icon, Print Icon,

E-mail Icon

These Parameters control which details should be displayed with the article (either in Blog Layout view or in full article view), as shown in the following screenshot

In the example below, all extras are set to show This results in a lot of "article clutter"; it's hard to find the real content in this detail overkill It's best to only display one or two details – if they add useful information

Setting Article Rating to Show will display a five point scale below the article title when the full article is shown; visitors can rate the article:

Title Linkable (Section Title

Linkable, Category Title

Linkable)

When set to Show, an article Title or Section or Category name

can be linkable; the visitor can click on it to navigate to the article/section/category

Content Language, Key

Reference These advanced options are only relevant when you have a

multilingual site

Alternative Read more: text Entering a Read more text will replace the default Read more link

with something specific to the article:

On the frontend, it will be shown as follows:

Filling out the Alternative Read more: text is good for the

findability of your content Search engines attach greater importance to a custom link (Recognizing Ugly Art) than to default text Read more It's better for usability too, as it allows you to better guide your visitors towards the article content

Metadata Information

Description, Keywords,

Robots, Author

Metadata information is used by search engines You can add an article description and keywords to help search engines index your content You'll read more on this in Chapter 12

Setting preferences for all new articles at once

You'll probably want to set some preferences for all your articles at once:

whether you want the author name displayed, whether the title should be a hyperlink, and so on To enter these site-wide article preferences, navigate to

Content | Article Manager and click on the Parameters button in the toolbar

After you have chosen the appropriate settings, these will apply to all new

articles, so it's a good idea to choose these settings before the bulk of your site content is created Of course, you can override these general settings by setting specific parameter choices when editing individual articles

Archiving articles

Your website is growing and there's a steady stream of new content Now what can you do with articles that are outdated? Of course, you can just unpublish them That way they're still available in the backend, but the site visitor cannot see them anymore

Another option is to create an archive Archived articles are still available, but they're no longer part of the "normal" site contents

Time for action – creating a news archive

Let's create an archive for some old news pages on the SRUP site:

1. Navigate to Content | Article Manager In the Select Category filter box, select

General News to see only the articles in that category.

2. Select two news articles to be archived In the following example, we've selected

New Ugly Paintings Discovered and Bob Ross Exhibition Announced:

3. Click on the Archive button in the toolbar A message appears to confirm both

articles are archived The article titles have changed to grey and the word

[Archived]

is displayed next to the title

You've created a (tiny) news archive now, but there's no way for the visitor to see the

contents Let's create a link:

4. Navigate to Menus| Main Menu| New Click on Articles|ArchivedArticle List Enter a Title for the hyperlink: News Archive Adjust any other settings you like and click on Save.

On the frontend, a link to the Archive is shown The visitor can filter (search) archived articles

by keyword or publication date:

What just happened?

You've created an archive for outdated articles The visitor can see an overview of the

archive contents by clicking on the News Archive link in the Main Menu Although this

archiving system can be useful, there's a catch; archived articles get a different URL This

is a disadvantage because existing links from other sites to your now archived contents will be broken

You cannot edit archived articles If you do want to change the content

of an archived article, you have to first unarchive it (using the Unarchive
