Uncaught TypeError: Cannot read property 'length' of undefined

Just wondering if anyone has any idea why this is happening.

Uncaught TypeError: Cannot read property 'length' of undefined jquery.DataTables.js:2107

happens when I type in anything in the genres column.

allan

I don't see a genres column I'm afraid?

It's pulled with the aaData. But not displayed until a row is Clicked. That's not the problem. The problem is it's not showing 0 records to display. Thinking it has something to do with the server side processing not retruning aaData at all because there's nothing there to put into the array. Just not sure how to fix it.

I'm a little confused I'm afraid. The table, when I load the page, shows 10 rows. If I click on 'A Good Day to Die Hard', a 'details' section opens. I don't see any errors.

You are expecting it to show 0 records on page load?

Allen yes when you search and there not be any records It should show No records found. But instead it errors out with property length. Even though I set the 0 records display on it. But i think it may have something to do with the aaData being sent from the server side processing. Seeing as it doesn't return a json aaData string if there's nothing found.

My assumption was that it read the iTotaldisplayrecords first so that if aaData was not present it would see that there's 0 records to display and would generate the 0 records to display message.

That would do it. DataTables expects an empty array if there are no records. Are you able to modify the returned json? If not you'd need to use fnServerData to make your own Ajax call and then reformat the returned json.

I can modify the json. if i know how to return an empty array for json. looking into any help would be appreciated.

Its simply `[]` . In PHP `echo json_encode( array() );` . Other languages will be different.

well since I'm using the the stock server_processing i added the array to the $object to start.
