How Can I Create a Secure Insert/Update Helper Function Using PDO Prepared Statements?

Insert/Update Helper Function Using PDO Prepared Statements

Considering the limitations of traditional plain MySQL driver, we seek a solution for creating an insert/update helper function that utilizes PDO prepared statements' features.

Prepared Statement Helper Function

function dbSet($fields, & $values) {
    $set = '';
    $values = array();

    foreach ($fields as $field) {
        if (isset($_POST[$field])) {
            $set .= "`$field` = ?,";
            $values[] = $_POST[$field];
        }
    }

    return rtrim($set, ',');
}

Usage

$fields = explode(" ","name surname lastname address zip fax phone date");
$_POST['date'] = $_POST['y']."-".$_POST['m']."-".$_POST['d'];

$query  = "UPDATE $table SET ".dbSet($fields, $values).", stamp=NOW() WHERE>

This helper function provides a straightforward approach to insert data using PDO prepared statements. It reduces code repetition and promotes security by eliminating the need for direct string concatenation.

Alternate Solution: Object-Relational Mapping (ORM)

For a more comprehensive solution, consider using an ORM like Doctrine. This approach provides an intuitive interface for managing database entities, allowing you to perform operations like saving data with minimal code:

$table = new Table();
$table->fromArray($_POST);
$table->save();

By incorporating the ORM solution, you can streamline your database operations and enforce data validation within your model.
