auPage

The auPage class is part of the auLib package. It provides functions for common page layout operations. It should be extended to handle the layout specific to a given website.

Usage

This class is meant to be extended as it includes only an incredibly basic layout. Every page on a website should create a page object for itself and use it for common layout operations.

Constants

_AU_PAGE_SITE_TITLE

If not defined already when auPage is included, this will get set to 'Generic Layout Class' and get used as the name of the website.

Protected Data

$started

True if the page has been started.

$ended

True if the page has ended.

$error

Any error messages that occurred before the page started.

$info

Any information messages that occurred before the page started.

$indent

Current indentation: should always be whitespace.

Public Functions

new auPage

new auPage()

Creates a new generic page layout object. If using a pages database, this is where the page record is looked up. This doesn't actually do anything, though it possibly should in classes that extend this class.

Error

Error($message, $detail)

Displays an error on the page. If the page hasn't been started yet, the error is saved and then displayed once the page starts.

• $message = Error message.
• $detail = Any details of the error. Default no details.

Info

Info($message)

Displays a message on the page. If the page hasn't been started yet, the message is saved and then displayed once the page starts.

• $message = Informational message.

HasQueuedMessages

HasQueuedMessages()

Determines whether the page has queued messages to show.

• @return = True if there are queued messages to show.

Start

Start($windowtitle, $title)

Writes out the part of the layout that comes before the page-specific content. Also writes any queued messages.

• $windowtitle = Title of the page to be displayed in the browser titlebar.
• $title = Title of the page, to be displayed on the page itself. Default is to use $windowvalue here too.

End

End()

Writes out the part of the layout that comes after the page-specific content.

Show404

Show404()

Sends a page not found header and then displays the 404 error page. Override this if your 404 page isn't /404.php.

Heading

Heading($heading, $id)

Writes out a heading on the page.

• $heading = Text of the heading.
• $id = ID of the heading, to work as #$id in links. Default is none.

SubHeading

SubHeading($heading, $id)

Writes out a sub-heading on the page.

• $heading = Text of the sub-heading.
• $id = ID of the sub-heading, to work as #$id in links. Default is none.

Protected Functions

Classes that extend auPage might find these functions useful, but they are not generally available.

FindParent

FindParent($url)

Finds the parent page that the current page belongs to. It takes into account both query string variables and directories.

• $url = URL of the current page.
• @return = URL of parent page.

ShowQueuedMessages

ShowQueuedMessages()

Displays all queued messages (errors and then information) on the page, once the page has been started.

Favicon

Favicon()

Writes out a link to the most specific favicon that can be found.

StyleSheets

StyleSheets()

Writes out a link to the relevant style sheets.

Scripts

Scripts($general)

Writes out a link to the relevant client-side scripts. This includes the general script and page- and/or directory-specific scripts found in the form /scripts/dir-subdir-page.js.

• $general = Name of script file to include on all pages, without path or extension. Optional; default is general.
