/**
|
|
* Generate the themed output.
|
|
*
|
|
* All requests for theme hooks must go through this function. It examines
|
|
* the request and routes it to the appropriate theme function. The theme
|
|
* registry is checked to determine which implementation to use, which may
|
|
* be a function or a template.
|
|
*
|
|
* If the implementation is a function, it is executed and its return value
|
|
* passed along.
|
|
*
|
|
* If the implementation is a template, the arguments are converted to a
|
|
* $variables array. This array is then modified by the module implementing
|
|
* the hook, theme engine (if applicable) and the theme. The following
|
|
* functions may be used to modify the $variables array. They are processed in
|
|
* this order when available:
|
|
*
|
|
* - template_preprocess(&$variables)
|
|
* This sets a default set of variables for all template implementations.
|
|
*
|
|
* - template_preprocess_HOOK(&$variables)
|
|
* This is the first preprocessor called specific to the hook; it should be
|
|
* implemented by the module that registers it.
|
|
*
|
|
* - MODULE_preprocess(&$variables)
|
|
* This will be called for all templates; it should only be used if there
|
|
* is a real need. It's purpose is similar to template_preprocess().
|
|
*
|
|
* - MODULE_preprocess_HOOK(&$variables)
|
|
* This is for modules that want to alter or provide extra variables for
|
|
* theming hooks not registered to itself. For example, if a module named
|
|
* "foo" wanted to alter the $submitted variable for the hook "node" a
|
|
* preprocess function of foo_preprocess_node() can be created to intercept
|
|
* and alter the variable.
|
|
*
|
|
* - ENGINE_engine_preprocess(&$variables)
|
|
* This function should only be implemented by theme engines and exists
|
|
* so that it can set necessary variables for all hooks.
|
|
*
|
|
* - ENGINE_engine_preprocess_HOOK(&$variables)
|
|
* This is the same as the previous function, but it is called for a single
|
|
* theming hook.
|
|
*
|
|
* - ENGINE_preprocess(&$variables)
|
|
* This is meant to be used by themes that utilize a theme engine. It is
|
|
* provided so that the preprocessor is not locked into a specific theme.
|
|
* This makes it easy to share and transport code but theme authors must be
|

* careful to prevent fatal re-declaration errors when using sub-themes that
|
|
* have their own preprocessor named exactly the same as it's base theme. In
|
|
* the default theme engine (PHPTemplate), sub-themes will load their own
|
|
* template.php file in addition to the one used for it's parent theme. This
|
|
* increases the risk for these errors. A good practice is to use the engine
|
|

|
|
* The same applies from the previous function, but it is called for a
|
|
* specific hook.
|
|
*
|
|
* - THEME_preprocess(&$variables)
|
|
* These functions are based upon the raw theme; they should primarily be
|
|
* used by themes that do not use an engine or by sub-themes. It serves the
|
|
* same purpose as ENGINE_preprocess().
|
|
*
|
|
* - THEME_preprocess_HOOK(&$variables)
|
|
* The same applies from the previous function, but it is called for a
|
|
* specific hook.
|
|
*
|
|
* There are two special variables that these hooks can set:
|
|
* 'template_file' and 'template_files'. These will be merged together
|
|
* to form a list of 'suggested' alternate template files to use, in
|
|
* reverse order of priority. template_file will always be a higher
|
|
* priority than items in template_files. theme() will then look for these
|
|
* files, one at a time, and use the first one
|
|
* that exists.
|
|
* @param $hook
|
|
* The name of the theme function to call. May be an array, in which
|
|
* case the first hook that actually has an implementation registered
|
|
* will be used. This can be used to choose 'fallback' theme implementations,
|
|
* so that if the specific theme hook isn't implemented anywhere, a more
|
|
* generic one will be used. This can allow themes to create specific theme
|
|
* implementations for named objects.
|
|
* @param ...
|
|
* Additional arguments to pass along to the theme function.
|
|
* @return
|
|
* An HTML string that generates the themed output.

|
|
* @{
|
|
* Functions and templates that present output to the user, and can be
|
|
* implemented by themes.
|
|
*
|
|
* Drupal's presentation layer is a pluggable system known as the theme
|
|
* layer. Each theme can take control over most of Drupal's output, and
|
|
* has complete control over the CSS.
|
|
*
|
|
* Inside Drupal, the theme layer is utilized by the use of the theme()
|
|
* function, which is passed the name of a component (the theme hook)
|
|
* and several arguments. For example, theme('table', $header, $rows);
|
|
* Additionally, the theme() function can take an array of theme
|
|
* hooks, which can be used to provide 'fallback' implementations to
|
|
* allow for more specific control of output. For example, the function:
|
|
* theme(array('table__foo', 'table), $header, $rows) would look to see if
|
|
* 'table__foo' is registered anywhere; if it is not, it would 'fall back'
|
|
* to the generic 'table' implementation. This can be used to attach specific
|
|
* theme functions to named objects, allowing the themer more control over
|
|
* specific types of output.
|
|
*
|
|
* As of Drupal 6, every theme hook is required to be registered by the
|
|
* module that owns it, so that Drupal can tell what to do with it and
|
|
* to make it simple for themes to identify and override the behavior
|
|
* for these calls.
|
|
*
|
|
* The theme hooks are registered via hook_theme(), which returns an
|
|
* array of arrays with information about the hook. It describes the
|
|
* arguments the function or template will need, and provides
|
|
* defaults for the template in case they are not filled in. If the default
|
|
* implementation is a function, by convention it is named theme_HOOK().
|
|
*
|
|
* Each module should provide a default implementation for themes that
|
|
* it registers. This implementation may be either a function or a template;
|
|
* if it is a function it must be specified via hook_theme(). By convention,
|
|
* default implementations of theme hooks are named theme_HOOK. Default
|
|
* template implementations are stored in the module directory.
|
|
*
|
|
* Drupal's default template renderer is a simple PHP parsing engine that
|
|
* includes the template and stores the output. Drupal's theme engines
|
|
* can provide alternate template engines, such as XTemplate, Smarty and
|
|
* PHPTal. The most common template engine is PHPTemplate (included with
|
|
* Drupal and implemented in phptemplate.engine, which uses Drupal's default
|
|
* template renderer.
|
|
*
|
|
* In order to create theme-specific implementations of these hooks,
|
|
* themes can implement their own version of theme hooks, either as functions
|
|
* or templates. These implementations will be used instead of the default
|
|
* implementation. If using a pure .theme without an engine, the .theme is
|
|
* required to implement its own version of hook_theme() to tell Drupal what
|
|
* it is implementing; themes utilizing an engine will have their well-named
|
|
* theming functions automatically registered for them. While this can vary
|
|
* based upon the theme engine, the standard set by phptemplate is that theme
|
|
* functions should be named either phptemplate_HOOK or THEMENAME_HOOK. For
|
|
* example, for Drupal's default theme (Garland) to implement the 'table' hook,
|
|
* the phptemplate.engine would find phptemplate_table() or garland_table().
|
|
* The ENGINE_HOOK() syntax is preferred, as this can be used by sub-themes
|
|
* (which are themes that share code but use different stylesheets).
|
|
*
|
|
* The theme system is described and defined in theme.inc.
