_update_manager_check_backends(&$form, $operation)
Checks for file transfer backends and prepares a form fragment about them.
Parameters
array $form: Reference to the form array we're building.
string $operation: The update manager operation we're in the middle of. Can be either 'update' or 'install'. Use to provide operation-specific interface text.
Return value
TRUE if the update manager should continue to the next step in the workflow, or FALSE if we've hit a fatal configuration and must halt the workflow.
File
- core/modules/update/update.manager.inc, line 84
- Administrative screens and processing functions of the Update Manager module.
Code
function _update_manager_check_backends(&$form, $operation) {
// If file transfers will be performed locally, we do not need to display any
// warnings or notices to the user and should automatically continue the
// workflow, since we won't be using a FileTransfer backend that requires
// user input or a specific server configuration.
if (update_manager_local_transfers_allowed()) {
return TRUE;
}
// Otherwise, show the available backends.
