I'm working on the server side. Everything works fine except if the words in the column I'm using are accented. How can I solve this problem?
PHP
`<?php
/* Database connection start */
$servername = "";
$username = "";
$password = "";
$dbname = "";
$conn = mysqli_connect($servername, $username, $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 =>'titulo',
1 => 'descripcion'
);
// getting total number records without any search
$sql = "SELECT titulo, descripcion ";
$sql.=" FROM ociospruebas";
$query=mysqli_query($conn, $sql) or die("employee-grid-data.php: get employees");
$totalData = mysqli_num_rows($query);
$totalFiltered = $totalData; // when there is no search parameter then total number rows = total number filtered rows.
if( !empty($requestData['search']['value']) ) {
// if there is a search parameter
$sql = "SELECT titulo, descripcion ";
$sql.=" FROM ociospruebas";
$sql.=" WHERE titulo LIKE '".$requestData['search']['value']."%' ";
// $requestData['search']['value'] contains search parameter
$sql.=" OR descripcion LIKE '".$requestData['search']['value']."%' ";
$query=mysqli_query($conn, $sql) or die("employee-grid-data.php: get employees");
$totalFiltered = mysqli_num_rows($query); // when there is a search parameter then we have to modify total number filtered rows as per search result without limit in the query
$sql.=" ORDER BY ". $columns[$requestData['order'][0]['column']]." ".$requestData['order'][0]['dir']." LIMIT ".$requestData['start']." ,".$requestData['length']." "; // $requestData['order'][0]['column'] contains colmun index, $requestData['order'][0]['dir'] contains order such as asc/desc , $requestData['start'] contains start row number ,$requestData['length'] contains limit length.
$query=mysqli_query($conn, $sql) or die("employee-grid-data.php: get employees"); // again run query with limit
} else {
$sql = "SELECT titulo, descripcion";
$sql.=" FROM ociospruebas";
$sql.=" ORDER BY ". $columns[$requestData['order'][0]['column']]." ".$requestData['order'][0]['dir']." LIMIT ".$requestData['start']." ,".$requestData['length']." ";
$query=mysqli_query($conn, $sql) or die("employee-grid-data.php: get employees");
}
$data = array();
while( $row=mysqli_fetch_array($query) ) { // preparing an array
$nestedData=array();
$nestedData[] = $row["titulo"];
$nestedData[] = $row["descripcion"];
$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

After data-base connect put: mysqli_set_charset($conn,"utf8");
