EmperorJazzy Posted April 24, 2012 Share Posted April 24, 2012 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?

Jessica Posted April 24, 2012 Share Posted April 24, 2012 try if(strlen($_POST['searchtext'])) as this will check if the string has more than 0 characters.

creata.physics Posted April 24, 2012 Share Posted April 24, 2012 Also take a look at php's trim function as it removes whitespace. if( trim( $_POST['searchtext'] ) != '' ) Will only allow the script to continue if actual characters were entered Link to comment https://forums.phpfreaks.com/topic/261551-basic-code-help-variable-contents-checking/#findComment-1340220 Share on other sites More sharing options...
