 Warning: require(theme/_modules/contact/search.php?q=saman): failed to open stream: No such file or directory in /home/dr7bf45v/public_html/search.php on line 17

Answer 1

Use this:

require 'theme/_modules/contact/search.php?q='.$q;

When you are using this...

require 'theme/_modules/contact/search.php?q={echo $q;}';

PHP is interpreting {echo $q;} literally, because it is encased in single quotes. Usually PHP will interpret {echo $q;} as you want in double quotes, but to be safe, use the . to tack something on to the end of a string. If you wanted to encase $q in double quotes without having to use the ., do it like this...

require "theme/_modules/contact/search.php?q=$q";

Answer 2

I think that you are trying to go over a wrong way.

You are trying to accomplish remote including. (1. you must allow it: including a remote file in PHP. 2. your link should looks like url).

Now you are trying to require theme/_modules/contact/search.php?q=saman it's mean that your script looking for file with name search.php?q=saman. Do you have that file? No. Only search.php.

But, I think, you are trying to pass variable to the file scope. There a better way to this. Just require it without extra params.

P.S. but if search.php receives value from GET and you need that result you could use curl because remote including is dangerous.
