Hello, i use for my website the datepicker plugin, works good.

<form action="<?=$_SERVER [ 'SCRIPT_NAME' ] ?>" method="post">
Datum: <input id="datepicker" name="datepicker" type="text" readonly="readonly"/>
<input type="submit" value="press button" />

But now i need also 3 Radio Buttons between date field and submit-button.

but i dont know how, perhaps anyone can help.

<?php
if( $_POST [ 'radiobutton' ] == "1" )
{
echo '...' ;
}
?>

<?php
if( $_POST [ 'radiobutton' ] == "2" )
{
echo '...' ;
}
?>

<?php
if( $_POST [ 'radiobutton' ] == "3" )
{
echo '...' ;
}
?>
