Search for NO VALUE in the Dropdown Menu

Search for NO VALUE in the Dropdown Menu

I have a dropdown menu (that is pulled from a table) the first Value is manually imputted "ALL MAKES" and the Value itself is blank. This returns all the Makes from the database! Selecting BMW from the Dropdown list returns only BMWs. So far so good.

OK, in order to make the result page a little bit nicer, I add a line, you selected "X" from the database and that returned "y" results. This works too.

However, with the blank value and all the rows returning, I can't get the return message to work. It just adds the first car returned from the database.

I want to use something like
<?php if ($WADAproducts->getColumnVal("vehicleMake") == "" ) echo "A message here"; ?>

This works fine:
<?php if ($WADAproducts->getColumnVal("vehicleMake") == "BMW" ) echo "A message here"; ?>

But I can't work out how to get the VALUE = NOTHING into the statement.

The serach string URL is as follows:

So you can see in the URL there's no value for the vehicleMake, but I can't get the PHP code to recognise NO VALUE.

I want the code to be like:


<?php if ($WADAproducts->getColumnVal("vehicleMake") == "NO VALUE / BLANK / NOTHING" )





So the end product would be

You searched for ALL MAKES (values of makes is blank)


You search for BMW (value of makes is BMW)

Or even
<?php if ($WADAproducts->getColumnVal("vehicleMake") == "IS NOT BLANK / HAS AT LEAST SOMETHING IN IT" )

Many thanks
