This is a PHP to SQL issue, not a jqGrid issue.
From what I can see, not understanding anything about PHP, your
case 'invid':
is not being applied to the varialbe $wh
To troubleshoot this put your debugger on and look at the output for $wh inside your
switch ($examp) {
case 1:
statement.
or just look at the actual SQL being sent to the database.

Hi Tim.
It was certainly a problem in PHP to SQL.
I mistakenly thought Jqgrid did everything. And of course, PHP and MYSQL code must be written by each user. Mainly MYSQL code for search functions.
The search module works for me as it is, but it was a difficult task to achieve.
For anyone who has the same doubt, the lesson learned is that: the code to execute searches with Jqgrid must be written yourself. The demos are just that, demos!
Thanks again Tim.
