|

Non menu code that was placed in hook_menu under the '!$may_cache' block
|
| 64 |
so that it could be run during initialization, should now be moved to hook_init.
|
| 65 |
Previously we called hook_init twice, once early in the bootstrap process, second
|
| 66 |
just after the bootstrap has finished. The first instance is now called boot
|
| 67 |
instead of init.
|
| 68 |
|
| 69 |
In Drupal 6, there are now two hooks that can be used by modules to execute code
|
| 70 |
at the beginning of a page request. hook_boot() replaces hook_boot() in Drupal 5
|
| 71 |
and runs on each page request, even for cached pages. hook_boot() now only runs
|
| 72 |
for non-cached pages and thus can be used for code that was previously placed in
|
| 73 |
hook_menu() with $may_cache = FALSE:
|
| 74 |
|
| 75 |
Dynamic menu items under a '!$may_cache' block can often be simplified
|
| 76 |
to remove references to arg(n) and use of '%<function-name>' to check
|
| 77 |
conditions. See http://drupal.org/node/103114.
|
| 78 |
|
| 79 |
The title and description arguments should not have strings wrapped in t(),
|
| 80 |
because translation of these happen in a later stage in the menu system.
