This code I'm using works fine but when I tried to query with a where clause, it looks like it doesn't work, it still displays all the data though I put a condition already. I also tried changing the way I put the where clause, but it says "no data found in the server" so I put the code back to its original form. I also tried putting a specific where clause like "where client = 'eadept'" but it still shows all details. This is my code.
session_start();
/* Database connection start */
$servername = "localhost";
$item = "root";
$password = "";
$dbname = "sample";
$conn = mysqli_connect($servername, $item, $password, $dbname) or die("Connection failed: " . mysqli_connect_error());
/* Database connection end */
// storing request (ie, get/post) global array to a variable
$requestData = $_REQUEST;
$columns = array(
// datatable column index => database column name
0 => 'facility',
1 => 'title',
2 => 'start',
3 => 'end',
4 => 'fee',
5 => 'status'
);
$uname = ($_SESSION['username']);
// getting total number records without any search
$sql = "SELECT facility, title, start, end, fee, status ";
$sql .= " FROM reservation WHERE client = '$uname'";
$query = mysqli_query($conn, $sql);
$totalData = mysqli_num_rows($query);
$totalFiltered = $totalData; // when there is no search parameter then total number rows = total number filtered rows.
$sql = "SELECT facility, title, start, end, fee, status ";
$sql .= " FROM reservation WHERE 1=1";
if(!empty($requestData['search']['value'])) { // if there is a search parameter, $requestData['search']['value'] contains search parameter
$sql .= " AND ( facility LIKE '" . $requestData['search']['value'] . "%' ";
$sql .= " OR title LIKE '" . $requestData['search']['value'] . "%' ";
$sql .= " OR fee LIKE '" . $requestData['search']['value'] . "%' )";
}
$query = mysqli_query($conn, $sql);
$totalFiltered = mysqli_num_rows($query); // when there is a search parameter then we have to modify total number filtered rows as per search result.
$sql .= " ORDER BY " . $columns[$requestData['order'][0]['column']] . " " . $requestData['order'][0]['dir'] . " LIMIT " . $requestData['start'] . " ," . $requestData['length'] . " ";
// $sql.="WHERE client = 'eadept'";
/* $requestData['order'][0]['column'] contains colmun index, $requestData['order'][0]['dir'] contains order such as asc/desc */
$query = mysqli_query($conn, $sql);
$data = array();
while($row = mysqli_fetch_array($query)) { // preparing an array
$nestedData = array();
$nestedData[] = $row["facility"];
$nestedData[] = $row["title"];
$nestedData[] = $row["start"];
$nestedData[] = $row["end"];
$nestedData[] = $row["fee"];
$nestedData[] = $row["status"];
$data[] = $nestedData;
}
$json_data = array(
"draw" => intval($requestData['draw']), // for every request/draw by clientside , they send a number as a parameter, when they recieve a response/data they first check the draw number, so we are sending same number in draw.
"recordsTotal" => intval($totalData), // total number of records
"recordsFiltered" => intval($totalFiltered), // total number of records after searching, if there is no searching then totalFiltered = totalData
"data" => $data // total data array
);
echo json_encode($json_data); // send data as json format
I'm referring to the query under the array. Can anyone please help and tell what to change so it will work?
