In addition to my post in this thread I've decided to post an extended example, which also implements functions for inserts and updates. I hope the code is straightforward enough. If not, reply and let me know.
The table structure I've used for my test is the following:
CREATE TABLE `contacts` ( `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `username` varchar(64) NOT NULL, `password` varchar(64) NOT NULL, `first_name` varchar(64) DEFAULT NULL, `last_name` varchar(64) DEFAULT NULL, `email` varchar(64) NOT NULL, PRIMARY KEY (`id`) )
And finally, here is how to use it:
<?php # Definition of my table structure $tableConfig = array ( 'contacts' => array ( 'id' => PDO::PARAM_INT, 'username' => PDO::PARAM_STR, 'password' => PDO::PARAM_STR, 'first_name' => PDO::PARAM_STR, 'last_name' => PDO::PARAM_STR, 'email' => PDO::PARAM_STR ) ); # Create a class instance include 'MyDB.class.php'; $myDB = new MyDB($tableConfig); # Create a data array for insert $newContact = array ( 'username' => 'pritaeas', 'password' => 'XXX', 'first_name' => 'Hans' ); $id = $myDB->insert('contacts', $newContact); # Create a data array for an update $updContact = array ( 'last_name' => 'Pollaerts', 'email' => 'firstname.lastname@example.org' ); $myDB->update('contacts', $updContact, array ('id' => $id)); # Show the recently inserted and updated record print_r($myDB->getRecord('contacts', array ('id' => $id))); ?>
Finally: a lot of room for improvement. Sanity checks, error checking, better/more where conditions, defining joins, extend configuration to allow table creation, and a lot more... I'll leave that to you.
