I am using a SQL insert statement into a table taking field from a survey form. It worked fine until they wanted to add some questions with checkbox answers. I created a checkbox array and have to sanitize the input. I can't figure out where the echo goes, I tried a couple of positions but it bombed the page - if I don't use the echo I get "array" inserted into the table instead of the value of the checkbox.
exploring is the checkbox array
Here is an example of the insert statement
INSERT INTO survey SET
,$exploring='" .$this->real_escape_string(implode(',', $_POST['exploring'])). "'
,stay_informed_yes='" . $this->real_escape_string($_POST['stay_informed_yes']) . "'
,stay_informed_no='" . $this->real_escape_string($_POST['stay_informed_no']) . "'
