The views modify query creates a views filter that lets you run PHP code to modify the query when it is build. In addition, it provides a Views field that lets you display any output generated by the code in the filter. This can be very useful when developing sites.
This is a module for advanced developers only ; only use it if you know what you are doing and understand the Views API.
Using this module can cause data loss. Only use it on development sites, and only if you know what you are doing
This module provides additional API functionality to other modules. You do not need this module unless you are instructed to by other modules to add it.
Elysia Cron extends Drupal standard cron, allowing a fine grain control over each task and several ways to add custom cron jobs to your site.
Set the timings and frequencies of each cron task (you can run some jobs every day at a specified hour, other only monthly and so on...). For each task you can simply choose between some frequently used options ("once a day", "once a month" ...), or use a powerful "linux crontab"-like syntax to set the accurate timings. You can even define your frequently used options to speed up site configuration.
Parallel execution of cron task: you can group jobs in channels and execute then simultaneously: so a task that takes a lot of time to execute won't block other tasks that need to be executed every 5 minutes...
You can disable all tasks, an entire channel or a single task.
Change the priority/order of task execution.
Manual force the execution of a cron tasks.
Detailed overview of cron status with time statistics for single tasks and channels.
powerful API for module developers: you can define extra cron tasks for your modules, each one with own default timings (site administrators can override them by configuration, other modules via hook_alter).
Administrators can define custom jobs (call to functions with parameters), via the "script" option.
Several optimization for frequent cron calls and error handling.
Protection from external cron calling by cron_key or allowed host list.
Elysia has no dependencies with contributed modules, and doesn't need to patch the core: it can be used in minimal Drupal installation with only core modules.
3rd party integration:
Ping feature, for external tracking services like host-tracker to tell whether cron is functioning properly on your site.
Drush support: you can call "drush elysia-cron run" to manually run extended cron.
CTools support for exports/backup of task settings.
Public Bookings allows registered and unregistered users to book predefined resources. These booking requests can then be approved, rejected, or modified by an admin, with notifications to the user.
Available and unavailable dates and times can be specified for each resource.
Requires the Bookings API module, the Date API (and its submodule Date Repeat API) and Views. Use the corresponding Bookings API release! Never ever mix DEV and STABLE between those two modules (e.g. dev from API, alpha from Public or vice vesa).
