未捕获的 SyntaxError：意外的标记 '('

Question

I am trying to insert data into a database and I keep getting this error in the inspect section in chrome.But in the editor it shows no error what could be the problem?我正在尝试将数据插入数据库，并且在 chrome 的检查部分中不断收到此错误。但是在编辑器中它没有显示错误可能是什么问题？ I have so far looked at some similar situations but I cant seem to figure it out.到目前为止，我已经看过一些类似的情况，但我似乎无法弄清楚。 So I am asking what the problem could be I used AJAX in some parts of the code.所以我问我在代码的某些部分使用了 AJAX 可能是什么问题。

<!DOCTYPE html>
<?php
session_start();
$mysqli = NEW MySQLi ('localhost','root','','laugh');

$resultGet = $mysqli ->query("SELECT * FROM event");
?>
<?php
session_start();
$mysqli = NEW MySQLi ('localhost','root','','laugh');

$resultSet = $mysqli ->query("SELECT * FROM ticket");
?>
<?php
$mysqli = NEW MySQLi ('localhost','root','','laugh');
if (isset($_POST['submit'])) {
    $event_id = $_POST['event_id'];
    $event = $_POST['name'];
    $ticket_id = $_POST['ticket_id'];
    $ticket = $_POST['name'];
    $price = $_POST['price'];
    $maxatt = $_POST['maxatt'];
    $sql = "insert into event(event_id,name,ticket,ticket_id,price,maxatt) values('$event_id','$event','$ticket_id',$ticket','$price','$maxatt')";
    if ($con->query($sql) === TRUE) {
        $last_id = $con->insert_id;
}
    
    echo'added successfully';
}

?>

Answer 1

This is from the addEvent_ajax2.php file that is used in the code above.这来自上面代码中使用的 addEvent_ajax2.php 文件。

<?php
    $mysqli = NEW MySQLi ('localhost','root','','laugh');
 
    $event = mysqli_real_escape_string($conn, $_POST['event'] .
    $tickett = mysqli_real_escape_string($conn, $_POST['ticket']);
    $maxatt = mysqli_real_escape_string($conn, $_POST['maxatt']);
 
 
    if(mysqli_query($conn, "INSERT * INTO booking (event_id,name,ticket,ticket_id,price,maxatt) VALUES ('$event_id','$event','$ticket_id',$ticket','$price','$maxatt')";

     echo '1';
    } else {
       echo "Error: " . $sql . "" . mysqli_error($conn);
    }
 
    mysqli_close($conn);
 
?>
