Question

How to use where clause in insert statement in php 5.1.6?

I have a global variable $module and i want to use where clause to distinguish my search result. where module= $module

I keep on getting error saying undefined variable $module

Without knowing anything about your code, I’d guess your problem is that you don’t escape your $module variable. try surrounding it with {}.

Example:

$query = “SELECT * FROM FOOBAR WHERE id = {$module}”;

Edit:

OP posted code on comments.

{} only works if you use quotation marks around your variable.

Change you code to :

$sql = "SELECT id, AssignmentName, file, deadline,name,module FROM Assignment_scripts where module={$module}";

Edit2:

Are you actually defining $module somewhere?
