Returns all blocks in the specified region for the current user.
@todo Now that the block table has a primary key, we should use that as the array key instead of MODULE_DELTA.
$region: The name of a region.
An array of block objects, indexed with the module name and block delta concatenated with an underscore, thus: MODULE_DELTA. If you are displaying your blocks in one or two sidebars, you may check whether this array is empty to see how many columns are going to be displayed.
function block_list($region) {
$blocks =& drupal_static(__FUNCTION__);
if (!isset($blocks)) {
$blocks = _block_load_blocks();
}
// Create an empty array if there are no entries.
if (!isset($blocks[$region])) {
$blocks[$region] = array();
}
else {
$blocks[$region] = _block_render_blocks($blocks[$region]);
}
return $blocks[$region];
