I'm running into something that seems quite trivial. I'm primarily a java programmer, but am creating a web site that has a bit of php code.
The problem is, I have created a search page in php that querries a db, and returns to self with the results.
One of the problems im having is that if a user goes directly to search php, then there is an error thrown because there is no variable sent to this page.
I need a way of "catching" this error without having to define.
I have tried something like:
Code: Select all
if( $_POST['myVar'] == NULL ){
$variableDefinedfromMyVar = "no search submited";
}I also need to catch other nonsubmitted variables but cant see how ???? any suggestions
