How Can I Create a PDO Prepared Statement Helper Function for Insert/Update Operations?

PDO Prepared Statements for Insert/Update Helper Function

In traditional MySQL driver scenarios, the dbSet() function is a valuable tool for generating SET statements. However, when utilizing PDO prepared statements, a similar approach is needed to maintain code dryness and flexibility.

PDO Prepared Statement Helper Function

The following helper function, dbSet(), can be utilized to achieve this:

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

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

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

Usage

Consider the following example:

$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>

ORM Alternative

For a more comprehensive solution, consider employing an ORM (object-relational mapping) framework such as Doctrine. With ORM, data population can be simplified considerably:

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

PDO Extension Class

For a customized solution, creating a PDO extension class can provide a convenient way to handle prepared statement queries efficiently, reducing the need for verbose bind_param() calls.
