Fatal error: Call to Undefined method mysqli_stmt::bindparam() PHP || MYSQL

Question

I’m with this error a few days ago, I’ve seen similar answers here on the site and also in the community in English, but I can not find the appropriate response to my situation.

Fatal error: Call to Undefined method mysqli_stmt::bindparam() in C: wamp www fanamol carrinho.php on line 164

By my search this error refers to the table name being wrong or fields, and I have already confirmed and everything is correct

Here is my code:

 if (!isset($_SESSION['itens'])){
    $_SESSION['itens']=array();      
}
           if(isset($_GET['add'])&& $_GET['add']=="carrinho") {
               $idproduto = $_GET['id'];
               if(!isset($_SESSION['itens'][$idproduto])){
                  $_SESSION['itens'][$idproduto]=1;  
               }else{
                       echo'O produto já se encontra no carrinho<br>';
               $_SESSION['itens'][$idproduto]+=1; 
               }
           }
            if (count($_SESSION['itens'])==0){
                echo'Carrinho vazio <br><a href="mol_compressao.php">Adicionar Itens</a>';
            }else{
                echo"
