I don't see any issues with your code. Maybe you can post your DataTables initialization config for review.

Could you also post your JSON data please. If you could post a link to the page showing the issue that would give us all the information required up front.

and my normal json data

kthorngren

I noticed you have "files":[] in the JSON response. Not sure if that is the source of the unknown field error. 'files` is not one of the required or optional fields that server side is expecting.

You can validate your code works with your data by creating a data variable containing the data object, remove the ajax and serverside config and add data: data into the DataTables init.

For example:

var data = [{
        "DT_RowId": "row_2169",
        "cicekci": {
            "id": "2169",
            "sid": "560",
            "cid": "6",
            "sandning": "Paket",
            "dorr": "1",
            "mottan": "Mimmi S\u00e4ll",
            "motta": "KRONF\u00c5GEL AB\nFranz\u00e9ngatan 5\n11251 Kungsholmen",
            "ovrig": "Levereras senast kl. 09.30\nPortkod: 4573",
            "levan": "22-03-2017",
            "sonduzenleyen": "",
            "datum": "2017-03-21",
            "datum2": ""
        },
        "u": {
            "username": "kungsholmen"
        }
    }, 
.......
]

Allan may find something else in the JSON but if not a link to a page showing the issue is needed.

and giving an error when i searching normaly working I had to say it at first sorry

allan

Could you show us the exact error message please?

It really would save us all a lot of time if you could link to the page so we could get this information immediately.

Thanks,
Allan

allan

I see you've actually sent me the link by PM - thanks.

Okay - so the error message is:

DataTables warning: table id=main - okänt område: (index 4)

which happens when you type a character into the DataTables global search box.

That appears to translate as "unknown area: (index 4)".

What does your action.php script contain please?

Allan

veryjackson

I send you my action.php code with pm

allan

Thank you. The issue is that you are using server-side processing, but two of your columns have columns.data set to be null and instead use client-side generated data.

With server-side processing obviously you can't search or sort client-side generated data, so you need to select one of:

• Disable search and sort on those columns (columns.searchable and columns.orderable)
• Use client-side processing
• Split the data into multiple columns

Allan

veryjackson

Thank you I found a solution with getFormatter

ManuelWenner

@allan I tried it by disabling search and sort on those columns but it's not working. I need server-side processing cause it's about 100.000 entries. What do you mean by split the data into multiple columns?

@veryjackson
How did you fix this?

allan

@ManuelWenner - If you link to your page I can take a look at it.

What I meant by splitting the data was that rather than having null data and client-side generating values from another more complex column, have the data you want in the columns which are currently null. It is not clear to me that advice would apply in your situation, since I don't know much about your specific case!

Allan
