mysqli has nothing to do with header redirects, I am not sure what you mean. Is the query that was giving you an error now working?
no error
Ah, OK, so youâre trying to sort something different out now? That would be good to mention. Can you explain in a bit more detail what problem you are having now, with the failing code?

after insert data in db cant on next page every time refreshing page new data go in db.
There is no redirect in your code.
Also, bind_values is better than bind_params as itâs easy to create bugs with bind_params

cant insert in db also go on next page:thinking:<button id=âbtn_room_searchâ action=âhttp://localhost/carbooking3/16%20y/korak22.php"class="sear-btnâ type=âsubmitâ>Search
with this code i have on next page but cant insert in db
<button id="btn_room_search" class="sear-btn" type="submit"><a href="http://localhost/carbooking3/16%20y/korak22.php?id=">Search</a></button>

Typo in this part: You have used the same parameter name twice - you canât do that, even if you wanted to insert the same value twiceâŚ

cant insert in db what about this one
Is that going to work, with a href inside a button definition? The button would submit the form, but if itâs processing the href instead of the button, then itâs just going to open korak.php with no value on the id parameter as a page, and not send the form contents. Thatâs a HTML thing really - do you get values in $_POST in your PHP code?
no i am not
if (isset($_POST[âsubmitâ])) {
added this and got an error
Whatâs on line 248 of that file?
If thatâs an answer to whether you are getting anything in the $_POST array, and you are not, then I would suggest you remove the <a href> part of the button code, and specify the action parameter in your opening form tag instead.
$mysqli->close();
If thatâs generating the error message, then it suggests that it didnât open in the first place. That suggests that your code to open the database connection is inside your if(), but your code to close the database is outside it. You should have both either inside or outside, so either they both execute, or neither does.
i am not sure what to do
