PHP: SQLSTATE[42000]: Syntax error or access violation: 1064 - php

Question

I know there are a lot of these questions concerning this error, but neither of the answers all over stack overflow, google etc. helped me with my problem. Maybe someone here can figure out, why this error constantly occures.
I am relatively new to PHP, so for little Applications I read a lot of tutorials and use them for my cases.
I tried to do a registration page using the following tutorial: http://www.codingcage.com/2015/11/ajax-registration-script-using-jquery-php.html
After everything isset and done, I always get the Error
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 !
...when I submit the registration. So I think it has to be in this part of the code:
$qry = "SELECT * FROM geraeteuser WHERE `user_email` LIKE :email";
$stmt = $db_con->prepare($qry);
$stmt->execute(array(":email"=>$user_email));
I tried everything using backtips here and there, but no matter what I do, it doesn't work.
The full Code looks like this ("geraetestatus" is the table name):
<?php
require_once "dbconfig.php";
if($_POST)
{
$user_name = $_POST['user_name'];
$user_email = $_POST['user_email'];
$user_password = $_POST['password'];
$password = md5($user_password);
try
{
$qry = "SELECT * FROM geraeteuser WHERE `user_email` LIKE :email";
$stmt = $db_con->prepare($qry);
$stmt->execute(array(":email"=>$user_email));
$count = $stmt->rowCount();
if($count==0){
$stmt = $db_con->prepare("INSERT INTO `geraeteuser`(user_name,user_email,user_password) VALUES(:uname, :email, :pass");
$stmt->bindParam(":uname",$user_name);
$stmt->bindParam(":email",$user_email);
$stmt->bindParam(":pass",$password);
if($stmt->execute())
{
echo "registered";
}
else
{
echo "Query could not execute !";
}
}
else{
echo "1"; // not available
}
}
catch(PDOException $e){
echo $e->getMessage();
}
}?>
and in the File "dbconfig.php", that is included, there is a pdo created like this:
<?php
$db_host = ***;
$db_name = ***;
$db_user = ***;
$db_pass = ***;
try{
$dsn = "mysql:host=$db_host;dbname=$db_name";
$db_con = new PDO($dsn, $db_user, $db_pass, array(PDO::ATTR_PERSISTENT => true));
$db_con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e){
echo $e->getMessage();
}?>
Does anyone have any suggestions for me to make this work? I tried nearly everything I could find here and in the google answers, but nothing helped.

Answer 1

In your Insert query String is a Missing closing bracket at the end.
You neee to Close VALUES( ... --> ) <--
