Retrieve table data from oracle database into datatable using PHP

dinusha_lakpriya

I'm trying to retrieve table data from oracle database into datatable using PHP. But i'm strugling with my datatable appears "No data available in table". Yes I see several posts that newer versions of the datatable is not compatible with oracle. How do i solve this issue?

fetch_data(); function fetch_data(){ $(document).ready(function() { $('#customer_table').DataTable({ "processing" : true, "serverside" : true, "ajax" : { url: "connect.php", type: "POST", data: {action: 'fetch'}, error: function(xhr, error, thrown) { console.log("AJAX error:", error, thrown); }, }, "columns": [ { data: 'FIRSTNAME' }, { data: 'LASTNAME' }, { data: 'NIC' } ], }); }); }

if (!$conn)
{
echo 'you fail';
}else
{
echo "success!";
}

// execute an SQL query
if(isset($_POST["action"]))
{
    if($_POST["action"] == 'fetch')
    {
        $query = "SELECT FIRSTNAME,LASTNAME,NIC FROM customer where NIC='830380124V'";
        $statement = oci_parse($conn, $query );
        $result = oci_execute($statement);
        if (!$result) {
            $error_message = oci_error($statement)['message'];
            echo "Error executing SQL query: $error_message";
            exit();
        }


        $data = array();
        // Loop through the results and add them to the array
        while ($row = oci_fetch_array($statement, OCI_ASSOC+OCI_RETURN_NULLS)) {
            $data[] = $row;
        }

        // close the database connection
        oci_close($conn);
        if (count($data) == 0) {
            echo "No rows returned from SQL query.";
            exit();
        }

        // Convert the data to JSON format
        $json_data = json_encode(array("data" => $data));
        echo $json_data;
    }
}
