How to insert a row in the sql table when clicking the button?

I have an immovable site that I am implementing the option of favorites. When opening the property and clicking favorite, it should insert in a new row in the favorite table, this one below (status 1 is favorite), and if "decrypt" it removes the line:

id|idusuario|imovel|status
1 |   789   | 552  |  1

My question is how to do this dynamically, Realaltime. I have the variables $idusuario and $idimovel.

PHP code to insert or remove from bookmarks, just do not know how to call dynamically, without opening another page:

$query = ("INSERT INTO favoritos (idusuario, imovel, status)
VALUES ('".$idusuario."', '".$idimovel."', '1'");
$db->setQuery($query);
$db->execute();

Using $.ajax(), can it be? If you can put an example

I don’t understand exactly where the difficulty is. Can you send the data to the server? Already have the connection to the database? The problem is building INSERT SQL code or more than that?

@bfavaretto do not know how to do it right, I know it can be with ajax, but I do not know how to use well the ajax, the ones I did went wrong, only know if type click and open another page to rotate the instruction to insert a new line

@Leocaracciolo would be a click to reverse an action already done by another click

If it were a input type="checkbox or two input type="radio" I think it would be better than a button that could confuse whether it was clicked or decrypted.

checkbox tagged > status=1 unchecked > status = 0. With radio one for status 1 and the other for status 0

When removing the bookmark, delete the line or change the status?

is to delete the line, right? $query=("DELETE FROM favorites WHERE idusuario = ". $idusuario." AND imovel = ". $idimovel) ;

The $.ajax():

$('#ID_DO_BOTAO').on('click',function(){
    $.ajax({
        type:"POST",
        url:"SEU_ARQUIVO.php",
        dataType:"Json",
        data:{'favorito':'favorito'},
        success:function(a){
            //retorno do php, ou um reload da pagina/elemento
        }
    });
});

SEU_ARQUIVO.php

if(($_POST['favorito'])&&($_POST['favorito']=='favorito')){
    //primeiro vc executa uma verificação se o usuário ja clicou ("SELECT * FROM favoritos WHERE idusuario = '$idusuario');
    if(usuario ja clicou){
        $query=("DELETE FROM favoritos WHERE idusuario = ".$idusuario." AND imovel = ".$idimovel);
    }else{
        $query = ("INSERT INTO favoritos (idusuario, imovel, status)
        VALUES ('".$idusuario."', '".$idimovel."', '1'");
        $db->setQuery($query);
        $db->execute();
    }
}
