22 Ad caches are defined through external modules. Ad caches are composed of a
|
|
pierre@1
|
23 module 'ad_cache_TYPE.module' and an include file 'ad_cache_TYPE.inc' that live
|
|
pierre@1
|
24 in the 'cache/TYPE' subdirectory where 'TYPE' is replaced with the type of
|
|
pierre@1
|
25 cache. For example, the included file cache lives in 'cache/file'.
|
|
pierre@1
|
26
|
|
pierre@1
|
27 The ad_cache_TYPE.inc file must have a function named ad_cache_TYPE() which is
|
|
pierre@1
|
28 used to display ads. It can optionally include a function titled
|
|
pierre@1
|
29 ad_cache_TYPE_variables used to extract any necessary variables from the global
|
|
pierre@1
|
30 $_GET array (this can also be used to override values that would normally be
|
|
pierre@1
|
31 set from $_GET). Any functions used by this code without bootstrapping Drupal
|
|
pierre@1
|
32 should also be in this file.
|
|
pierre@1
|
33
|
|
pierre@1
|
34 The ad_cache_TYPE.module file should define the drupal _help() hook so the
|
|
pierre@1
|
35 module can be enabled. It should also define the _adcacheapi() hook allowing
|
|
pierre@1
|
36 for configuration and processing. Any functions used by this code after
|
|
pierre@1
|
37 bootstrapping Drupal should also be in this module.
