This question already has an answer here:
I want to change the status in the database, with a select dropdown field. I am sending with ajax. The first row is always working, but with multiple data i cant update the second, third..etc
I tried with serialize(), but its not working.
select from database:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://code.jquery.com/jquery-1.11.3.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".allbooks").change(function(){
var allbooks = $(this).val();
var dataString = "allbooks="+allbooks;
$.ajax({
type: "POST",
data: dataString,
url: "get-data.php",
success: function(result){
$("#show").html(result);
}
});
});
});
</script>
</head>
<body>
<?php
define("HOST","localhost");
define("USER","root");
define("PASSWORD","");
define("DATABASE","hotel");
$euConn = mysqli_connect(HOST, USER, PASSWORD, DATABASE);
$selectRooms = "SELECT * FROM proba WHERE status='inRoom'";
$resultRooms = mysqli_query($euConn,$selectRooms);
if (mysqli_num_rows($resultRooms) > 0) {
echo "<div id='reserved' align='center'>";
While ($row = mysqli_fetch_array($resultRooms)) {
echo $row[1];
echo $row[0];
?>
<select name="allbooks" id="allbooks">
<option name="years">Choose</option>
<?php
for($i=1; $i<=19; $i++)
{
echo "<option value=".$i.">".$i."</option>";
}
?>
</select><br />
<?php }
}
else
echo "<h4>nothing in the db</h4></div>";
?>
<div id="show">
</div>
</body>
</html>
and getting the results:
if(!empty($_POST["allbooks"])) {
var_dump($_POST);
$id = 2;
//echo $_POST['modelS'];
$room = $_POST['allbooks'];
$sql2 = "UPDATE proba SET room='$room' WHERE id_reservation='$id'";
$query = mysqli_query($euConn, $sql2);
var_dump($query);
}
How to change, or what would be a simple solution? Thanks for the help.
