Load Layout in Action

public function smallAction(){

Get URL from PHP

<?php echo Mage::getUrl('mybanner/display/small') ?>

Process Input<form action="<?php echo Mage::getUrl('arithmetic/integer/multiply') ?>"

method="post"> <fieldset> <ul> <li> <label for="int1">Integer 1</label> <input type="text" id="int1" name="int1" /> </li> <li> <label for="int2">Integer 2</label> <input type="text" id="int2" name="int2" /> </li> <li><input type="submit" value="Multiply" /></li> </ul> </fieldset></form>

Is Form POST ?

$this­>getRequest()­>isPost()
