Do we still need to include =&Search=Search at the end of the url to clear searches?

Are there other options to clear the search? url rewrites?

I stumbled upon this old code (below) which I am sure you helped me with and have some questions.

1) I see this code is related to a session but I don't understand if it requires a user to be logged in or if a session can refer to a search session.

2) If this code is effective, and recommend are there any changes that should be made to work with mySQLi ?

3) If we use this code for mySQL page does it need to be modified (replace GET with something) (I am thinking that GET is vulnerable, but I am sorry, I don't recall the related details.)

CODE
<?php
if(!session_id()) session_start();
if(isset($_SESSION["WADbSearch1_events_Results"]) && isset($_GET['reset']) && $_GET['reset'] == "true") {
unset($_SESSION["WADbSearch1_events_Results"]);
}
?>

Thank you!

This code can be removed with MySQLi pages.

My search is not clearing. I did find another post where it was recommended to use the code below. I tried that but my search is still not clearing.

<?php
if (isset($_GET['clear']) && $_GET['clear'] == "true") {
$searchWADAtbl_tablename_WADbSearch1->clearSearch();
}
?>
I thought it may because I had mySQL and mySQLI on the same page so I temporarily removed that but still the page did not clear.

I have attached the page and pasted links in PM

Update your link to the page to:
https://performancehorsehotline.com/barrel-races/index2.php?Search=1

That will clear the search.

Thank you!

It appears that =&Search=Search and this ?Search=1 appended after the file name will clear the search.
Is one better than the other?

I was actually hoping that in mySQLi we could add a code to the page that would actually clear the search without anything appended to the URL for a cleaner look when pasting to social networks and sharing. Do you have a remedy for that other than url rewrites?

My url rewrites seem to be working to clear the search but the logic does not make sense to me. (examples in PM)

If you are coming from a social network or sharing then there will be no filter to clear, so you don't need to include it.

The search persists because if you have multiple pages of results you wouldn't want them to clear as you go from page to page, or if you view the details and come back.

I am using the links in my navigation to various pages or search results within pages. I guess I will experiment with my url rewrites.
Thank you,

Yes, you could always do a mod rewrite and use a link like /newsearch and have that rewritten to /barrel-races/index2.php?Search=1
