How to add one more query string with search query string

Question

I am using WordPress to create a recruitment site with subscription. This is what I did. Added a meta value for user role 'rec' which is a date of ending of subscription.

All worked fine.

But when recruiter searches from the form it ads ?as=something as the query string.

I want my url structure to be like this

/recruitment/?uid=4&as=it

uid is the User ID of a recruiter, it is being used to get the meta of date from user's data to find out if user can see this page or not. ?as=something is search string.

Right now whatever I add in the action of form when a user searches the url becomes

/recruitment/?as=it

What I did was I added the code like this in search form.

<form method="get" id="sul-searchform" action="<?php the_permalink() ?>&uid=<?php echo $my_uid;?>" class="wg_search">

Any help would be appreciated.

You should use 'add_query_arg' function, to do this.

It adds a single key & value or an associative array. You can set a key value to false to remove it from the query. Omitting the old query or the uri (second or third parameter) uses the $_SERVER value.

So in your case doing it like this should work:

... action="<?php echo add_query_arg( 'uid', get_current_user_id(), get_permalink() ); ?>" ...
