Force a limit

QuestionsForce a limit
Sam asked 5 years ago

Is there a way to force a limit so no more than say 5000 rows can be pulled out for any function? Whether it be export, search by date range etc.

Hello,

You can connect on_data_display event and truncate the $data array to 5000 if it is greater.
e.g.

$e["on_data_display"] = array("filter_display", null, true);
$grid->set_events($e);

function filter_display($data)
{
if (count($data["params"]) > 5000)
$data["params"] = array_slice($data["params"],0,5000);
}

Refer docs > event handling for help.

I was thinking more of a LIMIT X on all SQL queries.

The 'limit x' and offset is dynamcally set based on row numbers of grid and the current page. It will be difficult to override otherwise it will disturb the paging function.
