* defined, 'template' is not used.

|
* hook_theme() or defaults to $path.

|
* not specified in a later one, then the previous definition is kept.

|
* in hook_theme(). If there is more than one implementation and
|
490
|
* 'render element' is not specified in a later one, then the previous

|
882
|
*
|
883
|
* @section sec_theme_hooks Theme Hooks
|
884
|
* Most commonly, the first argument to this function is the name of the theme
|
885
|
* hook. For instance, to theme a taxonomy term, the theme hook name is
|
886
|
* 'taxonomy_term'. Modules register theme hooks within a hook_theme()
|
887
|
* implementation and provide a default implementation via a function named
|
888
|
* theme_HOOK() (e.g., theme_taxonomy_term()) or via a template file named
|
889
|
* according to the value of the 'template' key registered with the theme hook
|
890
|
* (see hook_theme() for details). Default templates are implemented with the
|
891
|
* PHPTemplate rendering engine and are named the same as the theme hook, with
|
892
|
* underscores changed to hyphens, so for the 'taxonomy_term' theme hook, the
|
893
|
* default template is 'taxonomy-term.tpl.php'.
|
894
|
*
|
895
|
* @subsection sub_overriding_theme_hooks Overriding Theme Hooks
|
896
|
* Themes may also register new theme hooks within a hook_theme()
|
897
|
* implementation, but it is more common for themes to override default
|
898
|
* implementations provided by modules than to register entirely new theme
|
899
|
* hooks. Themes can override a default implementation by implementing a
|
900
|
* function named THEME_HOOK() (for example, the 'bartik' theme overrides the
|
901
|
* default implementation of the 'menu_tree' theme hook by implementing a
|
902
|
* bartik_menu_tree() function), or by adding a template file within its folder
|
903
|
* structure that follows the template naming structure used by the theme's
|
904
|
* rendering engine (for example, since the Bartik theme uses the PHPTemplate
|
905
|
* rendering engine, it overrides the default implementation of the 'page' theme
|
906
|
* hook by containing a 'page.tpl.php' file within its folder structure).
|
907
|
*
|
908
|
* @subsection sub_preprocess_templates Preprocessing for Template Files
|
909
|
* If the implementation is a template file, several functions are called
|
910
|
* before the template file is invoked, to modify the $variables array. These
|
911
|
* fall into the "preprocessing" phase and the "processing" phase, and are
|
912
|
* executed (if they exist), in the following order (note that in the following
|
913
|
* list, HOOK indicates the theme hook name, MODULE indicates a module name,
|
914
|
* THEME indicates a theme name, and ENGINE indicates a theme engine name):
|
915
|
* - template_preprocess(&$variables, $hook): Creates a default set of
|
916
|
* variables for all theme hooks with template implementations.
|
917
|
* - template_preprocess_HOOK(&$variables): Should be implemented by the module
|
918
|
* that registers the theme hook, to set up default variables.
|
919
|
* - MODULE_preprocess(&$variables, $hook): hook_preprocess() is invoked on all
|
920
|
* implementing modules.
|
921
|
* - MODULE_preprocess_HOOK(&$variables): hook_preprocess_HOOK() is invoked on
|
922
|
* all implementing modules, so that modules that didn't define the theme
|
923
|
* hook can alter the variables.
|
924
|
* - ENGINE_engine_preprocess(&$variables, $hook): Allows the theme engine to
|
925
|
* set necessary variables for all theme hooks with template implementations.
|
926
|
* - ENGINE_engine_preprocess_HOOK(&$variables): Allows the theme engine to set
|
927
|
* necessary variables for the particular theme hook.
|
928
|
* - THEME_preprocess(&$variables, $hook): Allows the theme to set necessary
|
929
|
* variables for all theme hooks with template implementations.
|
930
|
* - THEME_preprocess_HOOK(&$variables): Allows the theme to set necessary
|
931
|
* variables specific to the particular theme hook.
|
932
|
* - template_process(&$variables, $hook): Creates an additional set of default
|
933
|
* variables for all theme hooks with template implementations. The variables
|
934
|
* created in this function are derived from ones created by
|
935
|
* template_preprocess(), but potentially altered by the other preprocess
|
936
|
* functions listed above. For example, any preprocess function can add to or
|
937
|
* modify the $variables['attributes_array'] variable, and after all of them
|
938
|
* have finished executing, template_process() flattens it into a
|
939
|
* $variables['attributes'] string for convenient use by templates.
|
940
|
* - template_process_HOOK(&$variables): Should be implemented by the module
|
941
|
* that registers the theme hook, if it needs to perform additional variable
|
942
|
* processing after all preprocess functions have finished.
|
943
|
* - MODULE_process(&$variables, $hook): hook_process() is invoked on all
|
944
|
* implementing modules.
|
945
|
* - MODULE_process_HOOK(&$variables): hook_process_HOOK() is invoked on
|
946
|
* on all implementing modules, so that modules that didn't define the theme
|
947
|
* hook can alter the variables.
|
948
|
* - ENGINE_engine_process(&$variables, $hook): Allows the theme engine to
|
949
|
* process variables for all theme hooks with template implementations.
|
950
|
* - ENGINE_engine_process_HOOK(&$variables): Allows the theme engine to process
|
951
|
* the variables specific to the theme hook.
|
952
|
* - THEME_process(&$variables, $hook): Allows the theme to process the
|
953
|
* variables for all theme hooks with template implementations.
|
954
|
* - THEME_process_HOOK(&$variables): Allows the theme to process the
|
955
|
* variables specific to the theme hook.
|
956
|
*
|
957
|
* @subsection sub_preprocess_theme_funcs Preprocessing for Theme Functions
|
958
|
* If the implementation is a function, only the theme-hook-specific preprocess
|
959
|
* and process functions (the ones ending in _HOOK) are called from the
|
960
|
* list above. This is because theme hooks with function implementations
|
961
|
* need to be fast, and calling the non-theme-hook-specific preprocess and
|
962
|
* process functions for them would incur a noticeable performance penalty.
|
963
|
*
|
964
|
* @subsection sub_alternate_suggestions Suggesting Alternate Hooks
|
965
|
* There are two special variables that these preprocess and process functions
|
966
|
* can set: 'theme_hook_suggestion' and 'theme_hook_suggestions'. These will be
|
967
|
* merged together to form a list of 'suggested' alternate theme hooks to use,
|
968
|
* in reverse order of priority. theme_hook_suggestion will always be a higher
|
969
|
* priority than items in theme_hook_suggestions. theme() will use the
|
970
|
* highest priority implementation that exists. If none exists, theme() will
|
971
|
* use the implementation for the theme hook it was called with. These
|
972
|
* suggestions are similar to and are used for similar reasons as calling
|
973
|
* theme() with an array as the $hook parameter (see below). The difference
|
974
|
* is whether the suggestions are determined by the code that calls theme() or
|
975
|
* by a preprocess or process function.
|
976
|
*
|
977
|
* @param $hook
|
978
|
* The name of the theme hook to call. If the name contains a
|
979
|
* double-underscore ('__') and there isn't an implementation for the full
|
980
|
* name, the part before the '__' is checked. This allows a fallback to a
|
981
|
* more generic implementation. For example, if theme('links__node', ...) is
|
982
|
* called, but there is no implementation of that theme hook, then the
|
983
|
* 'links' implementation is used. This process is iterative, so if
|
984
|
* theme('links__contextual__node', ...) is called, theme() checks for the
|
985
|
* following implementations, and uses the first one that exists:
|
986
|
* - links__contextual__node
|
987
|
* - links__contextual
|
988
|
* - links
|
989
|
* This allows themes to create specific theme implementations for named
|
990
|
* objects and contexts of otherwise generic theme hooks. The $hook parameter
|
991
|
* may also be an array, in which case the first theme hook that has an
|
992
|
* implementation is used. This allows for the code that calls theme() to
|
993
|
* explicitly specify the fallback order in a situation where using the '__'
|
994
|
* convention is not desired or is insufficient.
|
995
|
* @param $variables
|
996
|
* An associative array of variables to merge with defaults from the theme
|
997
|
* registry, pass to preprocess and process functions for modification, and
|
998
|
* finally, pass to the function or template implementing the theme hook.
|
999
|
* Alternatively, this can be a renderable array, in which case, its
|
1000
|
* properties are mapped to variables expected by the theme hook
|
1001
|
* implementations.
|
1002
|
*
|

|
1004
|
* An HTML string representing the themed output.
