How About Auto Loading Data Models

Consider you have a model like this

class samplemodel
{
public method setName(){/*set the name*}
public method setEmail(){/*set the email*}
}

Models are usually relevant to database tables. So if you have tables
with 10-12+ fields you may define accessor methods for all these
fields in your model. Now when loading data manually in the model
after submitting an HTML form you need to call them like this

$model = new samplemodel();
$model->setName("some name");
$model->setEmail("some email");
..........................

For models with few accessor methods it may be easy to type manually
all these data. But for 10-20-30 its totally ridiculous.

Thats why I designed this small Automatic Data Loader class which
takes a model as first argument and and data array as second argument
and then loads data from that array to that model. How is it looking?

<?
class dataloader
{
public static function load($module, $array)
{
$array = inputfilter::filter($array);
foreach ($array as $key=>$val)
{
if (is_callable(array($module,"get{$key}"),$callable))
{
echo "$key<br>";
call_user_func(array(&$module,"set{$key}"),$val);
}
}
}
}
?>

Now if you have two input object named "email" and "name" for example
in yoru html form and you call this loader as shown below, it will
load all the data from $_POST to the model automatically.

$model = new samplemodel();
dataloader::load($model, $_POST);

as the model is accessed with BY_REFERENCE style, so it will fetch
$model->setName() and $model->setEmail with appropriate $_POST data
and your model will be loaded automatically.

This comes really handy when you have to load models with many
accessor methods. I developed this object while working for Bangla
Chat Engine last night and Ha Ha HA, it really saves my time.

Caution: Using raw user submitted data from $_POST or $_GET is not
secured. You should filter them first.
