Question

I have created a for loop to display all the value from database, a textfield and button.
So for each value displayed there will be one textfield and “reply” button.
So when i click on the “reply” button, the text in the textfield and together with the id of the value i am “replying” to will be store into database.
But how am i suppose to get the id of the specific value i am “replying” to?
Below is the code in the jsp page

        <%  
    ConnectionDB uDB = new ConnectionDB();
    Comment[] comment = uDB.getComment();
        %> 
    <%
     for (int i = 0; i < comment.length; i++) {
    %> 
             <%=uDB.getMemberName(comment[i].getMemberId()).getFirstName()%>
             <%=uDB.getMemberName(comment[i].getMemberId()).getLastName()%>
             <%=comment[i].getCommentDesc() %>
          <br><input type="text" name="replycommenttxt" size="20"> 
              <input type="submit" name="replycommentbutton" value="reply"  >
    <% } %>

Answer 1

Store it in a hidden field of your form:

<input type="hidden" name"parentCommentId" value="<%= comment[i].getId() %>" />

You should really learn about the JSP EL, the JSTL, and the MVC pattern. Reading data from a database in a JSP and using scriptlets is really bad practice.
