<com:TContent ID="body" > <h1 id="1901">Page Configurations</h1> <p id="220217" class="block-content"> Page configurations are mainly used by <tt>TPageService</tt> to modify or append the application configuration. As the name indicates, a page configuration is associated with a directory storing some page files. It is stored as an XML file named <tt>config.xml</tt>. </p> <p id="220218" class="block-content"> When a user requests a page stored under <tt><BasePath>/dir1/dir2</tt>, the <tt>TPageService</tt> will try to parse and load <tt>config.xml</tt> files under <tt><BasePath></tt>, <tt><BasePath>/dir1</tt> and <tt><BasePath>/dir1/dir2</tt>. Paths, modules, and parameters specified in these configuration files will be appended or merged into the existing application configuration. Here <tt><BasePath></tt> is as defined in <a href="?page=Fundamentals.Services">page service</a>. </p> <p id="220219" class="block-content"> The format of a page configuration file is as follows, </p> <com:TTextHighlighter Language="xml" CssClass="source block-content" id="code_220097"> <configuration> <paths> <alias id="AliasID" path="AliasPath" /> <using namespace="Namespace" /> </paths> <modules> <module id="ModuleID" class="ModuleClass" PropertyName="PropertyValue" ... /> </modules> <parameters> <parameter id="ParameterID" class="ParameterClass" PropertyName="PropertyValue" ... /> </parameters> <include file="path.to.extconfig" when="PHP expression" /> <authorization> <allow pages="PageID1,PageID2" users="User1,User2" roles="Role1,Role2" verb="get" /> <deny pages="PageID1,PageID2" users="User1,User2" roles="Role1,Role2" verb="post" /> </authorization> <pages PropertyName="PropertyValue" ...> <page id="PageID" PropertyName="PropertyValue" ... /> </pages> </configuration> </com:TTextHighlighter> <p id="220220" class="block-content"> The <tt><paths></tt>, <tt><modules></tt>, <tt><parameters></tt> and <tt><include></tt> are similar to those in an application configuration. The <tt><authorization></tt> element specifies the authorization rules that apply to the current page directory and all its subdirectories. For more details, see <a href="?page=Advanced.Auth">authentication and authorization</a> section. The <tt><pages></tt> element specifies the initial values for the properties of pages. Each <tt><page></tt> element specifies the initial property values for a particular page identified by the <tt>id</tt> attribute. Initial property values given in the <tt><pages></tt> element apply to all pages in the current directory and all its subdirectories. </p> <p id="220221" class="block-content"> Complete specification of page configurations can be found in the <a href="<%~../../../../../docs/specs/config.dtd%>">DTD</a> and <a href="<%~../../../../../docs/specs/config.xsd%>">XSD</a> files. </p> <com:SinceVersion Version="3.1.1" /> <p class="block-content"> Since version 3.1.1, the <tt>id</tt> attribute in the <page> element can be a relative page path pointing to a page in the subdirectory of the directory containing the page configuration. For example, <tt>id="admin.Home"</tt> refers to the <tt>Home</tt> page under the <tt>admin</tt> directory. The <tt>id</tt> attribute can also contain wildcard '*' to match all pages under the specified directory. For example, <tt>id="admin.*"</tt> refers to all pages under the <tt>admin</tt> directory and its subdirectories. This enhancement allows developers to centralize their page configurations (e.g. put all page initializations in the aplication configuration or the root page configuration.) </p> </com:TContent>
