Basic Code Help - Variable Contents Checking

Recommended Posts

Hi All,

 

I'm having a major mind blank, and can't find anything in the previous posts resolving what I'm after.

 

I'm setting

 

$searchtext = $_POST['searchtext'];

 

I want to check $seachtext is not null.

 

I've seen isset($searchtext) but it doesn't solve my problem.

 

Basiclaly; I want an if statement to say if(isset($searchtext)) {......}

 

Thoughts?
