从mysql创建PFBC表单

Question

I found a good looking class for form creating. Hovewer I need to create forms dinamically, using output from database. Forms are being created this way:

$form->addElement(new Element\Textbox("Name:", "Name", array(
    "required" => 1
)));

So, If I want to add a different form I have to change new Element\Textbox to new Element\Password. Is it possible to create forms based on database results something like this:

foreach ($fields as $field) {
$form->addElement(new Element\$field->type("Name:", "Name", array(
    "required" => 1
)));
}

Right now it looks not right for me, and of course it's not working. So my question is, can I output this forms dinamically in different way, or should I check for another class ?

Answer 1

In case if $field->type is valid string of class name, for example "Password". Try to use:

foreach ($fields as $field) {
    $className = "\\PFBC\\Element\\{$field->type}";
    $form->addElement(new $className("Name:", "Name", array(
         "required" => 1
    )));
}
