Insert/Update Helper Function Using PDO
Question:
How can you create a helper function for inserts and updates using prepared statements in PDO?
Answer:
Here's a simple helper function that supports data insertion and updates using PDO:
function dbSet($fields, &$values) { $set = ''; $values = array(); foreach ($fields as $field) { if (isset($_POST[$field])) { $set .= "`$field` = ?,"; $values[] = $_POST[$field]; } } return rtrim($set, ','); } // Sample 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 function generates a SET statement and provides an array of values for binding. It handles the null check and ensures that only non-empty fields are included in the query.
