insert query using foreach loop receiving Uncaught Error: Call to a member function execute() on boolean

Question

I am trying to insert multiple rows at once to my db, I posted a question here the other day see here. Regarding my insert query only insert one row into the db, even if it was

Answer 1

Your SQL is generated incorrectly: INSERT INTO ord_dets(Order_ID,custmer_ip,Resturant_ID,Resturant_name,City_name, Product_Id,Product_Name,Product_Price,item_sub) VALUES (...,...,....)(...,...,....)(...,...,....)(...,...,....)(...,...,....)

This is how it looks like. Fix it ad there will be no error

Solution here is to add commas betweeen values: VALUES (...,...,....),(...,...,....),(...,...,....),(...,...,....),(...,...,....)

UPD: Actually I can't see where you add $query_parts to your query string

UPD2: this is how it should look to avoid sql injections:

$_query = "INSERT INTO ord_dets(Order_ID,custmer_ip,Resturant_ID,Resturant_name,City_name, Product_Id,Product_Name,Product_Price,item_sub) VALUES (?,?,?,?,?,?,?,?,?)";
$stmt = $dbc->prepare($_query);

for($x=0;$xexecute([$OI[$x] , $ip[$x], $_SESSION['rest_id'][$x] ,
          $rest_name[$x] , $City_name[$x] , $Product_Id[$x] ,
          $product_name[$x] , $prod_price[$x] ,$item_sub[$x]])) )
    {
        insertError = "There was an error inserting data: " . $query_run->error; 
          print "affected rows:" . $query_run->affected_rows;
    }
}
