* '''SMTP Host'''. The SMTP address to use when sending mail.  This is only used if '''Mailer''' is set to '''Sendmail'''.
 
 
==Permissions==
 
Joomla! version 3.0 will install with the same familiar back-end permissions as that of version 1.5. However, with 3.0, you can easily change these to suit the needs of your site.
 
 
The permissions for each action are inherited from the level above in the permission hierarchy and from a group's parent group. Let's see how this works. The top level for this is the entire site. This is set up in the Site->Global Configuration->Permissions, as shown below.
 
 
[[Image:Help30-Site-Global-Configuration-permissions-subscreen.png]]
 
 
You work on one Group at a time by opening the slider for that group. You change the permissions in the Select New Settings drop-down list boxes.
 
 
The options for each value are Inherited, Allowed, or Denied. The Calculated Setting column shows you the setting in effect. It is either Not Allowed (the default), Allowed, or Denied.
 
 
Note that the Calculated Setting column is not updated until you press the Save button in the toolbar. To check that the settings are what you want, press the Save button and check the Calculated Settings column.
 
 
===Setting Groups===
 
The first thing to notice are the nine Actions: Site Login, Admin Login, Super Admin, Access Component, Create, Delete, Edit, Edit State. and Edit Own. These are the actions that a use can perform on an object in Joomla. The specific meaning of each action depends on the context. For the Global Configuration screen, they are defined as follows:
 
 
;Site Login : Login to the front end of the site
 
 
;Admin Login : Login to the back end of the site
 
 
; Super Admin : Grants the user "super user" status. Users with this permission can do anything on the site. Only users with this permission can change Global Configuration settings (this screen). These permissions cannot be restricted. It is important to understand that, if a user is a member of a Super Admin group, any other permissions assigned to this user are irrelevant. The user can do anything action on the site. However, Access Levels can still be assigned to control what this group sees on the site. (Obviously, a Super Admin user can change Access Levels if they want to, so Access Levels do not totally restrict what a Super Admin user can see.)
 
 
;Access Component: Open the component manger screens (User Manager, Menu Manager, Article Manager, and so on)
 
 
;Create : Create new objects (for example, users, menu items, articles, weblinks, and so on)
 
 
;Delete : Delete existing objects
 
 
;Edit : Edit existing objects
 
 
;Edit State : Change object state (Publish, Unpublish, Archive, and Trash)
 
 
There are two very important points to understand from this screen. The first is to see how the permissions can be inherited from the parent Group. The second is to see how you can control the default permissions by Group and by Action.
 
 
This provides a lot of flexibility. For example, if you wanted Shop Suppliers to be able to have the ability to login to the back end, you could just change their Admin Login value to "Allowed". If you wanted to not allow members of Administrator group to delete objects or change their state, you would change their permissions in these columns to Inherited (or Denied).
 
 
It is also important to understand that the ability to have child groups is completely optional. It allows you to save some time when setting up new groups. However, if you like, you can set up all groups to have Public as the parent and not inherit any permissions from a parent group.
 
 
{{Chunk30:Help_screen_component_options_permissions_conclusion}}
 
 
==Text Filters==
 
Web sites can be attacked by users entering in special HTML code. Filtering is a way to protect your Joomla web site. Filtering options give you more control over the HTML that your content providers are allowed to submit. You can be as strict or as liberal as you desire, depending on your site's needs.
 
 
It is important to understand that filtering occurs at the time an article is saved, ''after'' it has been written or edited. Depending on your editor and filter settings, it is possible for a user to add HTML to an article during the edit session only to have that HTML removed from the article when it is saved. This can sometimes cause confusion or frustration. If you have filtering set up on your site, make sure your users understand what types of HTML are allowed.
 
 
The default setting in Joomla version 3.0 is that all users will have "black list" filtering on by default. This is designed to protect against markup commonly associated with web site attacks. So, if you do not set any filtering options, all users will have "black list" filtering done using the default list of filtered items. If you create a filter here, this overrides the default, and the default filter is no longer in effect.
 
 
To access the filtering settings, click on 'Text filters' tab at top.
 
 
[[Image:Help30-Site-Global-Configuration-text-filters-subscreen.png]]
 
 
===Column Headings===
 
* '''Filter Groups'''
 
*: For each user group on your site you specify which filter is applied to their edits.  The default filter is 'Default Black List'.
 
* '''Filter Type'''
 
*: There are five types of filter available:
 
** '''''Default Black List'''''
 
*** This filter excludes the following tags:
 
***: 'applet', 'body', 'bgsound', 'base', 'basefont', 'embed', 'frame', 'frameset', 'head', 'html', 'id', 'iframe', 'ilayer', 'layer', 'link', 'meta', 'name', 'object', 'script', 'style', 'title', 'xml'.
 
*** This filter also excludes the following attributes:
 
***: 'action', 'background', 'codebase', 'dynsrc', 'lowsrc'.
 
*** You can black list (disallow) additional tags and attributes using the '''Filter Tags''' and '''Filter Attributes''' columns.
 
** '''''Custom Black List'''''.  Only those tags and attributes listed in the '''Filter Tags''' and '''Filter Attributes''' columns will be disallowed.
 
** '''''White List'''''.  Only those tags and attributes listed in the '''Filter Tags''' and '''Filter Attributes''' columns will be allowed.
 
** '''''No HTML'''''.  This is the strictest filter you can apply.  All tags and attributes will be disallowed.
 
** '''''No Filtering'''''.  This is the most permissive filter you can apply. All tags and attributes, including the default black list tags and attributes will be allowed.
 
* '''Filter Tags'''
 
*: A list of tag names to add to the currently selected filter.  Separate each tag name with a space or a comma.  For the '''Default Black List''' filter these tags will be added to the default list of tags that are disallowed.  For the '''Customer Black List''' filter these tags are the only ones that are disallowed.  For the '''White List''' filter these are the only tags that are allowed.
 
* '''Filter Attributes'''
 
*: A list of attribute names to add to the currently selected filter.  Separate each attribute name with a space or a comma.  For the '''Default Black List''' filter these attributes will be added to the default list of attributes that are disallowed.  For the '''Customer Black List''' filter these attributes are the only ones that are disallowed.  For the '''White List''' filter these are the only attributes that are allowed.
 
 
===Notes===
 
* '''Combining filters.'''  If a user belongs to two different groups that have different filter settings, filters will combine in a permissive way. That is, the set of tags the user will be permitted to use will the combination of the tags that each group allows the user to use. So if the user is a member of one group that white lists a specific set of tags and another group that white lists a different set of tags, the user will be able to use both sets of white listed tags. White lists override blacklists, so if a user belongs to one group that black lists a tag and another group that white lists a tag, the user will be able to use that tag. A user that belongs to a group that has no filtering will be able to use any HTML regardless of filtering settings for other groups the user belongs to.
 
* '''Filter Application.'''  Please note that these settings work regardless of the editor that you are using.  Even if you are using a WYSIWYG editor, the filtering settings may strip additional tags and attributes prior to saving information in the database.
 
* '''Developer note'''.  The filtering parameters in config.xml have the new parameter menu="hide".  This hides the filters from the Menu Item's Component pane as you do not want cascading overrides to occur at the menu item level.
 
 
===Filter Examples===
 
'''Example One:'''
 
To allow people in a group to only submit content with basic HTML tags, use the following settings:
 
* Select White List as the Filter type
 
* Set the Filter tags to: p, b, i, em, br, a, ul, ol, li, img
 
* Set the Filter attributes to: href, target, src
 
 
'''Example Two:'''
 
To apply the default black-list filtering to a group, use the following settings:
 
* Select Black List as the Filter type.
 
* Leave the Filter Tags and Filter attributes fields empty.

Text Filters

Help-3x-configuration-global-configuration-text-filters.png

These text filter settings will be applied to all text editor fields submitted by users in the selected groups. These filtering options give more control over the HTML your content providers submit. You can be as strict or as liberal as you require to suit your site needs. The filtering is opt-in and the default settings provide good protection against markup commonly associated with Web site attacks.

Toolbar

At the top left you will see the toolbar:

Help30-Save-Close-Cancel-Help-toolbar.png

The functions are:

  • Save. Saves the global configuration settings and stays in the current screen.
  • Save & Close. Saves the global configuration settings and closes the current screen.
  • Cancel/Close. Closes the current screen and returns to the previous screen without saving any modifications you may have made.
  • Help. Opens this help screen.

Quick Tips

  • Most, if not all, of these settings can be set once and then left alone.
  • If major modifications need to be made, then consider taking the site offline to test it and to make sure everything is in working order.
  • The settings are saved in '<Joomla-root>/configuration.php'. You have to either activate the FTP-layer or make the 'configuration.php' file writable to save your changes.
