Member Function Documentation

Elgg\Database\Datalist::get (   $name)

Get the value of a datalist element.

Plugin authors should use elgg_get_config() and pass null for the site GUID.

Definition at line 74 of file Datalist.php.

Elgg\Database\Datalist::runFunctionOnce (   $functionname,
  $timelastupdatedcheck = 0 

Run a function one time per installation.

If you pass a timestamp as the second argument, it will run the function only if (i) it has never been run before or (ii) the timestamp is >= the last time it was run.

Functions are determined by their name. If you change the name of a function it will be run again.

Use $timelastupdatedcheck in your plugins init function to perform automated upgrades. Schedule a function to run once and pass the timestamp of the new release. This will cause the run once function to be run on all installations. To perform additional upgrades, create new functions for each release.

The function name cannot be longer than 255 characters long due to the current schema for the datalist table.

Elgg\Database\Datalist::set (   $name,

Set the value for a datalist element.

Plugin authors should use elgg_save_config() and pass null for the site GUID.

Names should be selected so as not to collide with the names for the site config.
Values set here are not available in $CONFIG until next page load.
string$nameThe name of the datalist

The BootService injects a pre-populated cache here. The constructor requires a cache as well because the installer doesn't fully boot.
