Question

i am trying to get values of checkboxes to insert them later on in database.
It is ok that unchecked checkboxes will not be sent to my servlet but the problem that i have when cheking more than one checkboxe it returns just the first I’am doing like that im my JSP:

<td><input type=checkbox id=\""+i+"\" name=cbo value=<%=object.getNom()+ object.getPrenom() %>  /> <%=object.getNom()+object.getPrenom()%></td>

And In the servlet the following:

String[] checkboxes = request.getParameterValues("cbo");
    System.out.println("operators checked are:" + checkboxes[i]);

Like you see I want to get all the values checked.
but if i check more than one only the first CB is shown in my servlet.

Thinks for help.

Answer 1

The request.getParameterValues() returns an array of values for multiple parameters with the same name found in the request.

If your request is OK, and by that I mean action?cbo=val1&cbo=val2&cbo=val3 etc, then, after you submit the form to your servlet, checkboxes should be ["val1", "val2", "val3"].

First check your request.

And one question: the following is in a loop, right?

System.out.println("operators checked are:" + checkboxes[i]);
