joomla for dummies phần 6 docx

To make Joomla end the publication of an article or unpublish the article, taking it off the site, enter the stop date in the Finish Publishing text box of the Parameters - Article sect

Figure 6-16:

Table of contents

In Figure 6-16, notice that Joomla uses the article’s title as the title of the first page in the article The text links are the names of page breaks, and Joomla displays << Prev and Next >> links to let users navigate from page to page The All Pages link in the table of contents displays the whole article without page breaks

Back (And Forth) to the Future:

Publishing at Different Times

You may have articles that need to appear on a certain schedule Perhaps you’re promoting a picnic (and need to take down the notice about it when the picnic is over) or a theatrical production (and need to display the notice only when tickets are available) Joomla helps with this task

Publishing articles in the future

You can create articles that will be published at some future time Suppose that your not-for-profit organization is running a raffle from now until

clicking the Add New Article icon in the control panel or by clicking the New

button in Article Manager

Suppose, however, that you don’t want this article to appear until December

To make sure of that, set the publication details in the Parameters - Article

section on the right side of the article editor To start publishing on

December 1, 2009, at midnight, for example, enter 2009-12-01 in the Start

Publishing text box (see Figure 6-17)

Be sure to use yyyy-mm-dd format when you enter the date.

Stopping publishing in the future

You can also end the publication of an article on a date in the future To

continue the example in the preceding section, perhaps the raffle ends

March 2, 2010, so you’d want to stop publication on that date

That’s easy enough to do To make Joomla end the publication of an

article (or unpublish the article, taking it off the site), enter the stop date

in the Finish Publishing text box of the Parameters - Article section (see

Figure 6-18)

To unpublish an article in Joomla, follow these steps:

1 Click the Article Manager icon in the control panel or choose Content ➪Article Manager in any back-end page to open Article

Manager.

2 In the article’s Published column, click its green check mark to change it to a red X.

Figure 6-19 shows the Privacy Policy article being unpublished

Unpublishing an article doesn’t remove the menu item that points to

it, however The menu item is still listed in its original menu, and if users click that item, they get an error page So you have to unpublish the menu item as well

3 To unpublish the menu item, click the Menu Manager icon in the control panel or choose Menus ➪Menu Manager in any back-end page

to open Menu Manager.

4 In the Published column of the appropriate menu item, click the green check mark to change it to a red X.

You’ve unpublished both the article and its menu item

Now you’re ready to tackle a big topic: user interaction One of the appealing

things about Joomla sites is that they promote interaction, which means

that users can submit their own articles to you How you actually handle

submissions is up to you

Making Your Joomla Site Interactive

When it comes to being a back-end administrator, you’re all-powerful in

Joomla You can sweep down from the heavens and change just about

anything on the site Your power is enormous

But where does that leave the site’s users? Part of making a site grow is

getting people involved; that’s how viral marketing works, for example

Joomla is up to the challenge

Three levels of users don’t have back-end privileges, but they can submit

and work with the content in your site if you allow them to:

Authors can submit articles, but someone in the back end has to approve them before they appear Editors can submit and edit articles And

publishers can submit articles, edit articles, and publish them (For more

details on these roles, see “Authors and Editors and Publishers, Oh My!”, later in this chapter.)

We’ve found that editors are more common than authors except on very large sites Site administrators seem to like enabling users to edit site content, which saves the administrators all the trouble of doing it themselves

Adding and managing users

To add users to your site and assign roles to them, you employ User Manager Follow these steps:

1 Click the User Manager icon in the control panel or choose Site ➪User

Manager in any back-end page to open User Manager.

2 Click the New button.

An Edit User page opens

3 In the User Details section, enter the user’s name, username, e-mail address, and password.

4 To give the user author, editor, or publisher privileges, select the appropriate role in the Group list (see Figure 6-20).

Figure 6-20:

Creating a

new author

Creating new users is just that quick The full details on User Manager are

laid out in detail in Chapter 9, if you’re interested

To illustrate the discussion in this section, we created three new users:

author, editor, and publisher, shown in User Manager in Figure 6-21 As you

might guess, these users’ privilege levels match their names, as you see in

the Group column

To let your new users submit content, you need an article submission page,

which you create in the following section

Creating an article submission page

Article submission pages let authors, editors, and publishers write their own

content and submit it You create an article submission page by creating a

new menu item that points to an article submission layout

Take a look at the default Joomla’s site’s front page, shown in Figure 6-22 A Key Concepts menu appears right above the login form that authors, editors, and publishers use to log in from the front end.

You can add a menu item to the Key Concepts menu and link that new menu item to an article submission page To create that new menu item in the Key Concepts menu, follow these steps:

1 Click the Menu Manager icon in the control panel or choose Menus ➪Menu Manager in any back end page to open Menu Manager.

2 Click the icon in the Menu Item(s) column of the Key Concepts row.

Menu Item Manager opens (see Figure 6-23)

3 Click the New button.

The New Menu Item page opens

4 Click Internal Link ➪Articles➪Article➪Article Submission Layout (see

Figure 6-24).

The Article Submission Layout page opens

Figure 6-22:

The Key Concepts

menu

5 In the Menu Item Details section, enter a title in the Title text box, and select a setting in the Access Level list (bottom-left corner of Figure 6-25).

Here are your access-level choices:

• Public: Everybody

• Registered: Logged-in users

• Special: Authors, editors, publishers, and administrators

6 Click the Apply or Save button to create your new menu item.

Congratulations — you’ve also created a new article submission page

Figure 6-25:

Configuring

a new article submission

But if the user named author used the login form on the front page to log in, she’d find the new menu item in the Key Concepts menu (see Figure 6-26) Cool!

In this section, we take a look at the capabilities enjoyed by the special users:

authors, editors, and publishers Different levels of users have different levels

of options available to them

Authors can write articles

Assuming that you’re logged in as an author, and you click the appropriate

menu item, the article submission page appears Then you can enter and edit

text, as shown in Figure 6-27

Figure 6-27:

Creating a

new article

In the figure, the author is submitting a new article named Neighborhood watch, with the dotted line indicating a Read More link (For details on Read More links, see Chapter 4.)

Submitting an article (author)

Farther down the page, you can select the proposed article’s section and category (In Figure 6-28, the author has selected the News section and the Latest category.) You can enter metadata for the article as well

When you’re done with the new article, click the Save button Joomla takes you back to the front page and displays a thank-you message (see Figure 6-29)

To log out as author, click the Logout button that appears on the front page after you log in

Figure 6-28:

Selecting

a new article’s section and

category

Approving an article (administrator)

So how do administrators learn about new article submissions? Log in to the back end as an administrator and check the mail icon in the top-right corner of the page If you see a number next to this icon, you have mail waiting (see Figure 6-30)

The number next to the people icon in the top-right corner tells you how many people are logged on currently.

Click the mail icon to open the page you see in Figure 6-31, and select the title

to open the message — in this case, a new article

You can read the submitted article in Article Manager as well by clicking the article’s title in that page

Figure 6-31:

A new message

Editors can make changes

Unlike authors, when editors log in, they see a page like the one shown in Figure 6-32 Notice the difference? An Edit icon at the top of all articles allows editors to revise articles

If you’ve logged in as an editor, click an article’s Edit icon to open its editing page (Figure 6-33 shows an example.) Make any changes to the article that you want; then click the Save button The changes are saved and appear on the site immediately

Sometimes when an editor tries to edit an article, he gets a message from Joomla saying that the article can’t be edited because someone else is already editing it — even if nobody is This situation can happen when editors don’t click the Save or Apply button to save their changes to an article before leav-ing the editor window To check in all checked-out articles — and make them accessible to editors — choose Tools➪Global Checkin in any back-end page.

Publishers can post articles

The last of the front-end-content manipulators are publishers In practical terms, publishers are the same as editors, except that they can also publish articles to the site

If you log in as a publisher and then create or edit an article, you see the two options that set publishers apart from editors: the Published and Show

on Front Page radio buttons (see Figure 6-34) (Start Publishing and Finish Publishing options are also available to publishers, as you see in the figure.)Those two options, which don’t appear for authors or editors, allow publishers to publish articles to the site — even on the front page

Figure 6-34:

Stand Up and Be Counted:

Tracking Page Hits

You can track the number of hits a page on your site has received Just check the Hits column in Article Manager (see Figure 6-35)

How can you reset the number of hits an article has to zero? Open the article

in the article editor, and click the Reset button on the right side, next to the

hit counter (the third item down on the right side)

See You Later, Alligator:

Taking the Site Offline

One day, you may get a call from a client, who screams into the phone,

“We’re not ready! Take the site offline!”

Take the site offline? How do you do that? You can use the Global

Configuration feature Follow these steps:

Working with Joomla Modules and Templates

This part has fun with Joomla modules and templates

Modules are those items that appear around the

periphery of your page: menus, polls, newsflashes, banners, search boxes, custom HTML, and more Joomla comes with dozens of built-in modules, and this part of the book is where you master them

We also cover working with Joomla templates in this part

Templates determine every aspect of the layout of your

pages, from where the modules go to the images and colors they use Although Joomla comes with limited template choices, you can download thousands of additional

templates from the Internet

Fun with Modules: Advertisements,

Archives, Banners, Custom

▶ Making a Custom HTML module

▶ Adding an RSS feed to your site

Joomla modules are those great embedded applications that appear

around the edges of your pages The newsflash (see Chapter 3), which rotates news stories on the front page, is a module So is the poll that

appears on the front page So are the very advertisements that can appear on Joomla pages

In fact, even menus are modules in Joomla.

The chapters in Parts I and II of this book provide a tour of content handling

in Joomla This chapter and the next one, however, cover modules

All about Modules

You handle modules in Joomla with Module Manager, which you open by choosing Extensions➪Module Manager in any back-end page Figure 7-1 shows Module Manager in the default Joomla installation

This tool is the main one we use in this chapter and Chapter 8

Figure 7-1:

In the rest of this chapter, you jump into some modules to see what they

offer and what makes them tick

The Advertisement Module:

The Advertisement module shows well, advertisements You can see it at

work on the right side of Figure 7-2 (You can’t miss it; it’s the module titled

Advertisement.)

You open the Advertisement module’s administration page by choosing

Extensions➪Module Manager to open Module Manager and then clicking the

module’s name

• user2: At user-defined position user2 (depends on template)

• user3: At user-defined position user3 (depends on template)

• user4: At user-defined position user4 (depends on template)

Joomla lists the modules that are already in the position you fied and allows you to select the order of the current module For the Advertisement module, you can set the order of the module in this list:

consistent with where the template you’re using places modules when you

select right, left, and so on For details on using templates, see Chapter 9
