javascript function not work in php properly

Question

This is my php code. after insert data, I am used alert message. Message appeared properly. but it not close when I click x cross sign.

if(isset($_POST['create_post'])){
 $name = $_POST['name'];
 $email = $_POST['email'];
 $country = $_POST['country'];
 $msg = $_POST['description'];
 $stmt = $connection->prepare("INSERT INTO message(name,email,country,msg,date) VALUES (?, ?, ?, ?,now())");
 $stmt->bind_param('ssss', $name,$email,$country,$msg);
 $stmt->execute(); 
 $stmt->close();
 if($stmt){
 echo '<div class= "alert">';
 echo ' <span class="closebtn" onclick="this.parentElement.style.display="none";">&times;</span> ';
 echo 'Your messaage has been sent ';
 echo ' </div>';
 }else{
 die('Query fialed' . mysqli_error($connection));
 }
}

Alert message part:

echo '<div class= "alert">';
echo ' <span class="closebtn" onclick="this.parentElement.style.display="none";">&times;</span> ';
echo 'Your messaage has been sent ';
echo ' </div>';

Answer 1

This line has too many nested " marks:

echo ' <span class="closebtn" onclick="this.parentElement.style.display="none";">&times;</span> ';

If you escape the inner ones properly (\") it will work.

Better yet, I'd just remove the echo statements, so it looks like this:

if($stmt){
 ?>
 <div class= "alert">
 <span class="closebtn" onclick="this.parentElement.style.display='none';">&times;</span> 
 Your messaage has been sent 
 </div>
 <?php
 }else{

• Rooter: can you edit y code properly, because your answer's code make an error for me :(
• Rooter: syntax error, unexpected 'none' (T_STRING), expecting ',' or ';' in C:\wamp\www\
• Rooter: if you can please edit my code properly,thank you very much
• Bing: Updated. Just forgot to remove one of the '; for the closing </div>
• Rooter: Thank you very much :D its working fine now :) and I have a question. why use php tags like this ?> <?php
