Error: Parameter number is invalid in PDO query

I have implemented the following PDO SQL Query:

$stmt = $pdo_conn->prepare("INSERT into ticket_updates (ticket_seq, notes, datetime, updatedby, customer, internal_message) values (:ticket_seq, :notes, :datetime, :updatedby, :customer, :internal_message) ");
                $stmt->execute(array(':ticket_seq' => $ticketnumber, 
                ':notes' => addslashes($message), 
                ':datetime' => date("Y-m-d H:i:s"),  
                ':updateedby' => $last_updated_by, 
                ':customer' => 'Y', 
                ':internal_message' => 'no'));

However, I encountered the following error:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: parameter was not defined' in /home/integra/public_html/autocheck/support_emails.php:479 Stack trace: #0 /home/integra/public_html/autocheck/support_emails.php(479): PDOStatement->execute(Array) #1 {main} thrown in /home/integra/public_html/autocheck/support_emails.php on line 479

I am unsure of what is causing this issue, as all other queries are functioning correctly.

Answer №1

When calling the function, you named the parameter as updatedby, but in the binding section, it is misspelled as updateedby. Make sure to correct this typo and check if it resolves your error.

Answer №2

It's likely just a typo, as the error message indicates that a parameter is undefined. Make sure to carefully review and double check all your parameters.

Answer №3

If that's the case, consider using unnamed parameters. This will help you avoid typing them multiple times and enhance maintainability, in my opinion.

$stmt = $pdo_conn->prepare(
    "INSERT into ticket_updates (".
        "ticket_seq, notes, datetime, updatedby, customer, internal_message)". 
        "values (?, ?, ?, ?, ?, ?)");

$stmt->execute(array(
            $ticketnumber, 
            addslashes($message), 
            date("Y-m-d H:i:s"),  
            $last_updated_by, 
            'Y', 
            'no'));
