use MRBS\Form\Form;
// A page designed to be used in Ajax POST calls for bulk deletion of entries.
// It takes an array of ids to be deleted as input. These are always assumed
// to be single entries. Returns the number of entries deleted, or some
// kind of string on failure (most likely a login page).
//
// If deleting lots of entries you may need to split the Ajax requests into
// multiple smaller requests in order to avoid exceeding the system limit
// for POST requests, and also the limit on the size of the SQL query once
// the ids are imploded.
//
// Note that:
// (1) the code assumes that you are an admin with powers to delete anything.
// It checks that you are an admin and so does not bother checking that
// you have rights in that particular area or room, nor does it check that
// the proposed deletion conforms to any policy in force.
// (2) email notifications are not sent, even if they are normally configured
// to be sent. Sending many thousands of emails in the space of a few
// seconds could overwhelm many mail servers, or break the usage policies
// on hosted systems.

require_once '../mrbs_sql.inc';
// Check the CSRF token
Form::checkToken();
// Check the user is authorised for this page

// Get non-standard form variables
$ids = get_form_var('ids', 'string', '[]', INPUT_POST);
// The ids are JSON encoded to avoid hitting the php.ini max_input_vars limit

// Everything looks OK - go ahead and delete the entries
// Note on performance. It is much quicker to delete entries using the
// WHERE id IN method below than looping through mrbsDelEntry(). Testing
// for 100 entries gave 2.5ms for the IN method against 37.6s for the looping
// method - ie approx 15 times faster. For 1,000 rows the IN method was 19
// times faster.
//
// Because we are not using mrbsDelEntry() we have to delete any orphaned
// rows in the repeat table ourselves - but this does not take long.

WHERE id NOT IN (SELECT repeat_id FROM " . _tbl('entry') . ")";
