Warning: PDOStatement::execute(): SQLSTATE[HY093]: - php

Question

I am trying to start getting to grips with PHP and also PDO. As I am starting now, I hear that PDO is more beneficial, that is why I am not using the more popular mysqli.
I am having trouble getting data inserted into my db using PDO. I wanted to try and use prepared statements to minimize sql injection. I have tried many ways and keep hitting a brick wall.
I could do with some pointers please.
here is the error message.
Warning: PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number: parameter was not defined in C:\wamp\www\test-search\insert_property.php on line 61
This is the relevant php code.
// Insert Property
// Include db
include 'db_connect_pdo.php';
include 'defines.php';
try {
// create SQL
$sql = "INSERT INTO property (pid, title, intro_en, description_en, bedrooms,
bathrooms, address, city, country, stype, ptype, price)
VALUES(:pid, :title, :intro_en, :description_en, :bedrooms, :bathrooms, :address,
:city, :country, :stype, :ptype, :price)";
// prepare the statement
$stmt = $conn->prepare($sql);
// bind the parameters and execute the statement
$stmt->bindValue(':pid', $pid);
$stmt->bindValue(':title', $title);
$stmt->bindValue(':intro_en', $intro_en);
$stmt->bindValue(':description_', $description_en);
$stmt->bindValue(':bedrooms', $bedrooms);
$stmt->bindValue(':bathrooms', $bathrooms);
$stmt->bindValue(':address', $address);
$stmt->bindValue(':city', $city);
$stmt->bindValue(':country', $country);
$stmt->bindValue(':stype', $stype);
$stmt->bindValue(':ptype', $ptype);
$stmt->bindValue(':price', $price);
// execute the statement
$stmt->execute();
}
catch (Exception $e)
{
echo $e->getMessage();
}
$conn = null;
?>

Not sure where it is going wrong, any advice will be greatly appreciated.

Answer 1

Your error is this line:
$stmt->bindValue(':description_', $description_en);
Should be:
$stmt->bindValue(':description_en', $description_en);
