+[b]Red Development - A Guide To The Schema System[/b]

+

+A schema, in a nutshell, is a collection of settings for a bunch of variables to define

+certain elements of a theme.  A schema is loaded as though it were part of config.php

+and has access to all the same information.  Importantly, this means it is identity aware,

+and can be used to do some interesting things.  One could, for example, restrict options

+by service class, or present different options to different members.

+

+By default, we filter only by whether or not expert mode is enabled.  If expert mode is

+enabled, all options are presented to the member.  If it is not, only scheme, background

+image, font face, and iconset are available as choices.

+

+A schema is loaded *after* the member's personal settings.  Therefore, to allow a member

+to overwrite a particular aspect of a schema you would use the following syntax:

+[code]

+        if (! $foo)

+            $foo = 'bar';

+[/code]

+However, there are circumstances - particularly with positional elements - where it

+may be desirable (or necessary) to override a member's settings.  In this case, the syntax

+is even simpler:

+[code]

+            $foo = 'bar';

+[/code]

+Members will not thank you for this, however, so only use it when it is required.

+

+If no personal options are set, and no schema is selected, we will first try to load a schema

+with the file name "default.php".  This file should never be included with a theme.  If it

+is, merge conflicts will occur as people update their code.  Rather, this should be defined

+by administrators on a site by site basis.

+

+You schema does not need to - and should not - contain all of these values.  Only the values

+that differ from the defaults should be listed.  This gives you some very powerful options

+with very few lines of code.

+

+Note the options available differ with each theme.  The options available with the Redbasic 

+theme are as follows:

+

+[li] nav_colour

+	The colour of the navigation bar.  Options are red, black and silver.  Alternatively, 

+	one can set $nav_bg_1, $nav_bg_2, $nav_bg_3 and $nav_bg_4 to provide gradient and

+	hover effects.[/li]

+[li] banner_colour

+	The font colour of the banner element.  Accepts an RGB or Hex value.[/li]

+[li] bgcolour

+	Set the body background colour.  Accepts an RGB or Hex value.[/li]

+[li] background_image

+	Sets a background image.  Accepts a URL or path.[/li]

+[li] item_colour

+	Set the background colour of items.  Accepts an RGB or Hex value.[/li]

+[li] item_opacity

+	Set the opacity of items.  Accepts a value from 0.01 to 1[/li]

+[li] toolicon_colour

+	Set the colour of tool icons.  Accepts an RGB or Hex value.[/li]

+[li] toolicon_activecolour

+	Set the colour of active or hovered icon tools.[/li]

+[li] font_size

+	Set the size of fonts in items and posts.  Accepts px or em.[/li]

+[li] body_font_size

+	Sets the size of fonts at the body level.  Accepts px or em.[/li]

+[li] font_colour

+	Sets the font colour.  Accepts an RGB or Hex value.[/li]

+[li] radius

+	Set the radius of corners.  Accepts a numeral, and is always in px.[/li]

+[li] shadow

+	Set the size of shadows shown with inline images.  Accepts a numerical 

+	value.  Note shadows are not applied to smileys.[/li]

+[li] converse_width

+	Set the maximum width of conversations.  Accepts px, or %.[/li]

+[li] nav_min_opacity[/li]
