Articles hold your text content, together with any pictures or media files you have attached. The look and feel of your web site is largely influenced by your site administrator’s fluency with the Article Manager and the associated parameters. Using the Article Manager The Article Manager provides access to all the articles in your system, as well as the tools to create new articles and to copy, move, edit, delete, and archive them. Taken all together, this is one of the most powerful and most important screens in your Joomla! system. To view the Article Manager, either click the icon of the same name on the control panel, or select Article Manager under the Content menu on your main admin nav bar. In either event, the Article Manager opens in your web browser, as shown in Figure 5.8. The toolbar at the top of the Joomla 1.5.x Article Manager provides quick access to the following functions: l Unarchive: Select one or more archived articles from the list and then click this icon to unarchive them. l Archive: Select one or more active articles from the list and then click this icon to archive them. l Publish: Select one or more articles from the list and then click this icon to publish them. l Unpublish: Select one or more articles from the list and then click this icon to unpublish them. Part II: Working with Content and Users 92 l Move: Select one or more articles from the list and then click this icon to move the items into a different category. l Copy: Select one or more articles from the list and then click this icon to make copies of them. l Trash: Select an article from the list and then click this icon to move the article to the Trash. l Edit: Select an article from the list and then click this icon to edit the article details. l New: Click to add a new article. l Parameters: Click to edit the Global Article parameters. l Help: Click to access the online Help files related to the active screen. FIGURE 5.8 The Article Manager interface in Joomla! 1.5.x, showing the default sample data installed. Below the toolbar and above the list of articles are five sorting and searching tools to help you manage long lists of articles: l The Filter field on the left works like a search box. Type a word or phrase into the field and then click Go. The page reloads and displays the results of the search. To clear the screen and return to a full listing, click the Reset button. Chapter 5: Managing Content 93 l The Select Section filter enables you to filter and display the articles according to the sec- tion to which they are assigned.

Click the name to edit the article. l Published: A green checkmark in this column indicates the publication state of the article. As indicated by the legend that appears at the very bottom of the Article Manager, the icon that is displayed indicates the publication state. You can click the icon to publish or unpublish the article, depending on its state: l A yellow dot beside an Article icon indicates the article is approved and scheduled for publication but is pending. l A green checkmark beside an Article icon indicates the article is currently published. l A red circle with an X beside an Article icon indicates the article was published but has expired. l A red circle with an X in it (without an Article icon) indicates the article is neither published nor scheduled for publication. l A gray circle with a crossbar (without an Article icon) indicates the article is archived. Tip If you hover the cursor over the Published icon, the system displays the article’s start and stop publication dates. l Front Page: A green checkmark in this column indicates that the article is assigned to appear on the front page of the site. A red circle with an X in it indicates the article is not assigned to the front page. Click the icon to toggle between the two states. Part II: Working with Content and Users 94 l Order: The number indicates the order of the article, relative to the other articles. You can reorder the articles by either clicking the green arrows to move an item up or down in the order, or by entering numbers for the order and then clicking the save icon at the top of the column. l Access Level: Shows the access level set for that article.

The default value can be altered by changing the List Length option on the Global Configuration Manager. Creating articles New articles are created by clicking the New icon on the toolbar at the top right of the Article Manager. Clicking the New icon opens the New Article dialogue, as shown in Figure 5.9. The toolbar at the top of the New Article dialogue provides quick access to the following functions: l Preview: Click to open a lightbox showing how the article will appear to a site visitor. Note that the article does not appear inside your site’s page template; the only way to see the article inside your site template is to publish it and view it from the front end. l Save: Click this icon to save your work, create a new article, and exit the New Article dia- logue. l Apply: Click this icon to save you work without exiting from the New Article dialogue. l Cancel: Cancels the task and exits the New Article dialogue. l Help: Click to access the online Help files related to the active screen. Chapter 5: Managing Content 95 The fields in the workspace are: l Title: Type in this field a name for the article. The value in this field will be used as the article’s title. This field is required. l Alias: Enter an alias for the system to use internally for this article. Note that this field only accepts lowercase letters without spaces. If you leave this field blank, the system will modify the article’s title for use as the alias.

This field is required. l Published: Set to Yes to publish the article. l Front Page: Set to Yes to display this article on the site’s front page. l Category: Select a category for the article from the combo box. l Text field (no label): Enter your content for the article in this box.

At the time of article creation, much of this information will be blank. FIGURE 5.9 The New Article dialogue in Joomla 1.5.x.

Complete any other fields you wish; all other fields are optional. 8. Click the Save icon on the toolbar at the top right to save your new article. The dia- logue closes and returns you to the Article Manager. Setting the parameters Articles in Joomla! include parameters that you can use to affect the article display and behavior. Note that many of the parameter options are repeats of the same choices available in the Global Article parameters, or in the Menu Item Type parameters. The settings you indicate in the Article parameters will take precedence over other parameter settings, thereby allowing you to tailor the display of individual articles. Global parameters The Global Article parameters are accessed by clicking the Parameters icon on the Article Manager toolbar. Clicking the icon causes a menu to appear, as shown in Figure 5.10. Set the options you wish; then click the Save button to set the changes and close the pop-up window. Options set through the Global parameters controls apply to all articles in the system, unless they are overridden by the individual article’s parameters. Note Where there is a conflict between the Global Article Parameters and the individual article parameters, the set- tings in the article parameters are applied by the system. Chapter 5: Managing Content 97 FIGURE 5.10 The Global Article Parameters pop up in Joomla! 1.5.x. The following parameters are included here: l Show Unauthorized Links: This control determines whether users are shown links to content for which they lack sufficient access privileges to view. If set to Yes, the links appear, but when a user without sufficient privileges clicks on the link, they will be prompted to log in; if they do not log in, they will not be able to view the article. The default state is No. l Show Article Title: Whether the article title is displayed along with the content. The default state is Yes. l Title Linkable: Set this parameter to Yes if you want the article title to be hyperlinked to the full article.

Chapter 5: Managing Content 99 Article parameters Individual Article parameters (shown in Figure 5.11) are accessed via the Article Editing dialogue. The Article parameters section of all articles contains the following options: l Author: The combo box next to this field contains a list of users; select from this box to specify the author of the article and override the default setting. l Author Alias: This field is normally left blank; enter text here if you wish to display a name other than the name associated with the user in the system. l Access Level: Sets the access level for this article.

The default value is Never. Any time you provide an opportunity for users to input HTML into your site, you create the possibility that harmful, or even malicious, code can find its way into your system. In order to help prevent this from happening, Joomla! has added content filtering to the system. The filtering works by assessing the HTML that is input by the users and checking it against a black list to see if the code is permitted. Joomla! provides content filtering in the default system and applies it to all users except for the Super Administrator. The default settings can be overridden by the Filter parameters contained in the Global Article Parameters, discussed previously. The default Joomla! system includes a pre-determined Black List that contains the following tags: applet, body, bgsound, base, basefont, embed, frame, frameset, head, html, id, iframe, ilayer, layer, link, meta, name, object, script, style, title, and xml. The Black List also excludes the following attributes by default: action, background, codebase, dyn- src, lowsrc. Through the Global parameters, you can either add new terms to the Black List or you can create a White List that specifically allows certain elements to be used. The parameters also give you a way to specify which users will be subject to the controls. Note that setting a control for one user group auto- matically sets that control for all children user groups. Content filtering Part II: Working with Content and Users 100 FIGURE 5.11 The Article parameters. Advanced parameters Like the Article parameters, the Advanced parameters are accessed via the Article Editing dialogue, as shown in Figure 5.12. The Advanced parameters section of all articles contains the options outlined below. Note that the default value for all parameters is Use Global, which specifies that the system will apply the values set in the Global Article parameters. Setting a contrary value will override the Global parameter setting: l Show Title: Whether the article title is displayed along with the content. l Title Linkable: Set this Parameter to Yes if you want the article title to be hyperlinked to the full article.
