SQL from form

Hi,
I am a newbie, this is my first post (please go easy).

Iam at the moment trying to set up a query for someone looking for a property on an estate agents website.

From a drop down menu, the user can:
select an area (where they may like to live) from a list of areas.
select an amount of bedrooms from a list of bedrooms
select a minimum price from a list of prices
select a maximum price from a list of prices.

The query I worked out for this is as follows:
$data = mysql_query("SELECT * FROM property WHERE area like '$area' and bedrooms like '$bedrooms' AND price BETWEEN '$min_price' AND '$max_price'") or die(mysql_error());

This seems to work fine and shows all the properties that meet the criteria onto my webpage.

However, I then thought, someone may not care which area they live in and want to see all properties in all the areas, so I decided to add the option 'All areas' to my 'areas' list, I then did the same for the other lists, eg 'all bedrooms' option to my bedrooms list and so on.

I am now trying to write a query that incorporates where the 'all..' option is selected and have become very stuck!
Can someone set me off in the right direction for this.
I hope that makes sense?!?!

if the value is all, then you want to exclude the element in the where clause (ie you don't want to add it)
