JSON array accent display

I'm trying to display a json array with contents from my database but when their is accents in the database the json array doesn't want to be displayed, their is my code:
<?php
include 'connect.php';
header('Content-Type: text/plain; charset=UTF-8') ;
$serial = 1;
$statment = mysqli_prepare($conn, "SELECT * FROM lesson WHERE serial = ?");
mysqli_stmt_bind_param($statment, "i", $serial);
mysqli_stmt_execute($statment);
mysqli_stmt_store_result($statment);
mysqli_stmt_bind_result($statment, $serial, $by, $type, $description, $lesson, $nb_q);
$response = array();
$response["success"] = false;
while(mysqli_stmt_fetch($statment)){
$response["success"] = true;
$response["serial"] = $serial;
$response["by"] = $by;
$response["type"] = $type;
$response["lesson"] = $lesson;
$response["description"] = $description;
$response["nb_q"] = $nb_q;
for ($i = 1; $i <= $nb_q; $i++) {
$statment2 = mysqli_prepare($conn, "SELECT * FROM question WHERE 4_l_id = ? AND q_num = ?");
mysqli_stmt_bind_param($statment2, "ii", $serial, $i);
mysqli_stmt_execute($statment2);
mysqli_stmt_store_result($statment2);
mysqli_stmt_bind_result($statment2, $question, $nb_answer, $type, $correct_1, $for_l_id, $id, $q_num);
while(mysqli_stmt_fetch($statment2)){
$response["q".$i] = $question;
}
}
}
echo json_encode($response, JSON_UNESCAPED_UNICODE);
?>
Thank you for your answers

I found a good code but thank you for your help,
<?php
include 'connect.php';
$serial = 1;
$statment = mysqli_prepare($conn, "SELECT * FROM lesson WHERE serial = ?");
mysqli_stmt_bind_param($statment, "i", $serial);
mysqli_stmt_execute($statment);
mysqli_stmt_store_result($statment);
mysqli_stmt_bind_result($statment, $serial, $by, $type, $description, $lesson, $nb_q);
$response = array();
$response["success"] = false;
function utf8_encode_all(&$value)
{
if (is_string($value)) return utf8_encode($value);
if (!is_array($value)) return $value;
$ret = array();
foreach($dat as $i=>$d) $ret[$i] = utf8_encode_all($d);
return $ret;
}
while(mysqli_stmt_fetch($statment)){
$response["success"] = true;
$response["serial"] = $serial;
$response["by"] = utf8_encode_all($by);
$response["type"] = utf8_encode_all($type);
$response["lesson"] = utf8_encode_all($lesson);
$response["description"] = utf8_encode_all($description);
$response["nb_q"] = $nb_q;
for ($i = 1; $i <= $nb_q; $i++) {
$statment2 = mysqli_prepare($conn, "SELECT * FROM question WHERE 4_l_id = ? AND q_num = ?");
mysqli_stmt_bind_param($statment2, "ii", $serial, $i);
mysqli_stmt_execute($statment2);

}
}
}
$array = array_map('htmlentities',$response);
$json = html_entity_decode(json_encode($array));
echo $json;

Having json inside autocomplete

How come autocomplete doesnt work when I got json data that has items in it? I can se that it is becoming a list, but it is not filling with names.
Example of my json data: http://nettport.com/no/stram/search.php?term=e
<script>
$(function() {
$( "#inp_meal_a_0" ).autocomplete({
source: 'search.php'
});
$('#inp_meal_a_0').on('autocompleteselect', function (e, ui) {
var val = $('#inp_size_a_0').val();
var energy = ui.item.energy;
var proteins = ui.item.proteins;
var carbohydrates = ui.item.carbohydrates;
var fat = ui.item.fat;
$("#inp_energy_a_0").val((energy*val)/100);
$("#inp_proteins_a_0").val((proteins*val)/100);
$("#inp_carbs_a_0").val((carbohydrates*val)/100);
$("#inp_fat_a_0").val((fat*val)/100);
});
});
</script>
Search.php
<?php
header('Content-type: text/html; charset=windows-1252;');

$host = $_SERVER['HTTP_HOST'];
if($host == "127.1.1.0"){

$value = stripslashes($value);
}
//Change decimal values from , to . if applicable
if( is_numeric($value) && strpos($value,',') !== false ){
$value = str_replace(',','.',$value);
}
if( is_null($value) ){

}

return $value;
}

$term = strip_tags(stripslashes($term));
$term = trim($term);
$term = strtolower($term);
$term = $term . "%";
$part_mysql = quote_smart($term);
//get matched data from skills table
$x = 0;
$query = "SELECT cc_id, cc_food_name, cc_manufactor_name, cc_serving_size, cc_serving_mesurment, cc_energy, cc_proteins, cc_carbohydrates, cc_fat FROM stram_calorie_calculation WHERE cc_food_name LIKE $part_mysql";

like button on click ajax not working

I want to make an ajax request on click with jquery, but it's not working:
This is what I have:
The button:
$photos_box .= '<a id="' . $imgID . '" class="like_button">' . $like . '</a>';
Maybe there's an error in the script:
// Like function
$('.like_button').click(function() {
$(this).toggleClass('liked');
var status = '';
if ($(this).hasClass('liked')) {
status = 'like';
$(this).html('Ya no me gusta');
console.log('like_works');
} else {
status = 'unlike';
$(this).html('Me gusta');
console.log('unlike_works');
}
var data = {
img_id : this.id,
sta : status
};
$.ajax({
type : 'POST',
url : '/includes/like.php',
data : data
}).done(function(reslike) {
if (reslike == 1) console.log('ajax_works');
});
});
And this is the like.php file:
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
sec_session_start();
// User id
if (login_check($mysqli) == true) {
$user_id = $_SESSION['user_id'];
}
$img_id = $_POST['img_id'];
$status = $_POST['sta'];
$stmt = $mysqli->prepare("SELECT * FROM img_likes WHERE img_id = ? AND user_id = ?");
$stmt->bind_param("ii", $img_id, $user_id);
$stmt->execute();
$result = $stmt->get_result();
$usr_likes = $result->num_rows;
if ($status == 'like') {
if ($usr_likes == 0) {
$stmt->close();
$stmt = $mysqli->prepare("INSERT INTO img_likes (img_id, user_id) VALUES(?, ?)");
$stmt->bind_param("ii", $img_id, $user_id);
$stmt->execute();
}
}
else if ($status == 'unlike') {
if ($usr_likes != 0) {
$stmt->close();
$stmt = $mysqli->prepare("DELETE FROM img_likes WHERE img_id = ? AND user_id = ?");
$stmt->bind_param("ii", $img_id, $user_id);
$stmt->execute();
}
}
}
At last! Thanks to everyone. Hope my code help someone.

Check the URL in your ajax request, I'm not certain but I don't think '../includes/like.php' is a valid URL I think you actually have to give it a valid server URL like "http://example.com/includes/like.php"

dynamic checkbox by getting data from database and tick the checkbox accordingly

what i am trying to do is getting data from database and tick the checkbox according to that but i did not success any idea?
i am not sure what is the problem
JS code
function editPer(role_pk) {
var xmlHttp = new XMLHttpRequest();
xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState === 4) {
var jsonObj = JSON.parse(xmlHttp.responseText);
document.getElementById("role_pk1").value = jsonObj.pk;
document.getElementById("role_name1").value = jsonObj.name;
for (var i = 1; i < 29; i++){
if (jsonObj.permission_fk+i != null)
document.getElementById("per"+i).checked = true;
else
document.getElementById("per"+i).checked = false;
}
}
};
xmlHttp.open("GET", "classes/controller/RoleController.php?action=getp&pk=" + role_pk, true);
xmlHttp.send();
/*
* Reset error message
* Show update role button
*/
resetErrorMessage("roleMessage");
showUpdateRoleButton();
$("#perModalDetail").modal('show');
};
PHP code RoleController.php
}else if ($action == "getp") {
if (isset($pk)) {
/*
* Select single Role value
*/
$itemArray = $roleDao->getp($pk);
if (count($itemArray) == 0) {
echo NULL;
} else {
echo json_encode($itemArray[0]);
}
}
PHP code in the class roleDao
public function getp($pk) {
$query = "SELECT pk, name FROM roles WHERE pk=".$pk.";";
$result = mysql_query($query, $this->dbconn);
$itemArray = array();
while ($row = mysql_fetch_row($result)) {
$item = array("pk" => $row[0], "name" => $row[1]);
array_push($itemArray, $item);
}
$query = "SELECT permission_fk FROM role_permission WHERE role_fk=".$pk.";";
$result = mysql_query($query, $this->dbconn);
$i=1;
while ($row = mysql_fetch_row($result)) {
$item = array("permission_fk$i" => $row[0]);
$i++;
array_push($itemArray, $item);
}
//print $itemArray;
return $itemArray;
}

If removeEvent clicked delete from mysql

JS file this deletes by button the Event
buttons: {
save : function() {
calEvent.start = new Date(startField.val());
calEvent.end = new Date(endField.val());
calEvent.title = titleField.val();
calEvent.body = bodyField.val();
$calendar.weekCalendar("updateEvent", calEvent);
$dialogContent.dialog("close");
},
"delete" : function() {
calEvent.id = id;
$.post("events.php?action=del&id="+calEvent.id);
$calendar.weekCalendar("removeEvent", calEvent.id);
$dialogContent.dialog("close");
},
cancel : function() {
$dialogContent.dialog("close");
}
}
}).show();
PHP File
if($action == 'save')
{
$title = $_REQUEST['title'];
$body = $_REQUEST['body'];
$start_time = (int)$_REQUEST['start'];
$start_time = $start_time + 60*60;
$end_time = (int)$_REQUEST['end'];
$end_time = $end_time + 60*60;
$start = date('c',$start_time);
$end = date('c',$end_time);
$sql = "INSERT INTO meeting_rooms_calendar(title,body,start,end) VALUES ('$title','$body','$start','$end')";
$result = mysql_query($sql, $link);
}
elseif ($action == 'del')
{
$del = "DELETE FROM `agenda`.`meeting_rooms_calendar` WHERE `meeting_rooms_calendar`.`id` = VALUES ('$id')";
$result = mysql_query($del, $link);
}
else
{
$sql= "SELECT id, title, body,
DATE_FORMAT(start, '%Y-%m-%dT%H:%i' ) AS startTime, DATE_FORMAT(end, '%Y-%m-%dT%H:%i' ) AS endTime
FROM meeting_rooms_calendar
ORDER BY start DESC";
$result = mysql_query($sql, $link);
This wont delete from database, what am I doing wrong to delete it from database?
