What considerations should be taken into account when updating menu categories in PHP to ensure consistency across related tables?
When updating menu categories in PHP to ensure consistency across related tables, it is important to use transactions to maintain data integrity. By wrapping the update queries in a transaction, you can ensure that either all changes are committed or none are, preventing inconsistent data across tables.
<?php
// Start the transaction
$pdo->beginTransaction();
try {
// Update menu category in main table
$stmt1 = $pdo->prepare("UPDATE menu_categories SET category_name = :category_name WHERE category_id = :category_id");
$stmt1->execute(['category_name' => $new_category_name, 'category_id' => $category_id]);
// Update menu category in related table
$stmt2 = $pdo->prepare("UPDATE related_table SET category_name = :category_name WHERE category_id = :category_id");
$stmt2->execute(['category_name' => $new_category_name, 'category_id' => $category_id]);
// Commit the transaction
$pdo->commit();
} catch (Exception $e) {
// Rollback the transaction if an error occurs
$pdo->rollBack();
echo "Error updating menu categories: " . $e->getMessage();
}
?>
