How Can I Verify Successful PDO MySQL Inserts?

Determining Success of PDO MySQL Insert Operations

Inserting data into a MySQL database using PHP can be simplified with the help of PDO. However, it's often essential to verify the success of such operations.

Query Execution:

To insert a record using PDO, you can execute a prepared statement as follows:

$stmt = $pdo->prepare("INSERT INTO table (field1, field2) VALUES (:field1, :field2)");
$stmt->bindParam(':field1', $field1, PDO::PARAM_STR);
$stmt->bindParam(':field2', $field2, PDO::PARAM_STR);
$stmt->execute();

Checking for Success:

To determine if the insert was successful, PDO provides several methods:

• PDOStatement->execute(): Returns true on success and false on failure.
• PDOStatement->errorCode(): Returns the error code, if any.

For example:

if ($stmt->execute()) {
    echo "Record inserted successfully.";
} else {
    $error = $stmt->errorCode();
    echo "Error: ".$error;
}

Additional Considerations:

• Duplicate Records: If the error code returned by PDOStatement->errorCode() is related to duplicate entry, you can handle it appropriately.
• Database Validation: Remember that even if the PDO insert is successful, database-level constraints may prevent the insertion of a record.

By utilizing these methods, you can programmatically determine the success of your PDO MySQL insert operations, ensuring that your database insertions are handled accurately.
