Good Afternoon.

Im using data tables to get a responsive editing table.
However, the table its not filling at all.
Its reading the info from database but not displaying on the table, just showing no matching records found.

Here is my server response
{"draw":"1","recordsTotal":16126,"recordsFiltered":0,"data":[]}

    I'm not familiar with PHP but the problem is occurring in your server script. It is not returning any data, ie "data":[]. I would start by debugging the SQL query that is being built and the result in $result = $connect->query($query);. That is what you are building the returned dataset from.

    A few things I can see off the bat, but nothing that would explain the zero records:

    1)

    'draw' => $_POST['draw']

    For security make sure you do:

    'draw'      =>  intval($_POST['draw'])
    

    It prevents injection attacks.

    2) You don't use $query1 anywhere.

    3) $result = $connect->query($query); seems a little odd after you've just done a similar query to get the row count.

    As I say though, I don't think any of them explain the actual issue. I would suggest logging out $query and seeing what is being built.

    You might also want to consider using our demo SSP class as a library to build up your own script.
