PHP: calling the value of a checkbox

[Newmand2]

I am looking to create a form, whereby if a checkbox is checked, another bit of the form appears. It should go a bit like this, right?



<input type="checkbox" value="0">

<?php
if checkbox = 1 print '....rest of form....'
else print ''
end if
?>



I realise that I probably have to call the value with something like 'checkbox.value = 1'. How is this done... otherwise where am I going wrong?

I think that for something like that you'd need to use javascript rather than php.

Yeah, and this line:

<input type="checkbox" value="0">

Should be:

<input type="checkbox" value="0" />
