i am creating a website with a database attached using netbeans, and MySQL.
I have written a piece of code for information submitted in a form on the website to be entered into the database, however the actual input is not inserted into the database, only ‘$_POST[username]’,’$_POST[date]’,’$_POST[message1]’,’$_POST[acknowledgment]’… i want these values to be the values the user inputs.

can anyone help me to fix this or suggest anything please

    $_POST[username] notation is for PHP I guess. Use something like this :

    <sql:update var="messages" dataSource="jdbc/noticeboard">
    INSERT INTO messages (username, postedon, message, acknowledgment)
    VALUES ('<%=request.getParameter("username")%>',
        '<%=request.getParameter("date")%>',
        '<%=request.getParameter("message1")%>',
        '<%=request.getParameter("acknowledgment")%>')
</sql:update>

    Update :

    Try some this also, i’m not sure whether could parse the parameters.

    <sql:update var="messages" dataSource="jdbc/noticeboard">
INSERT INTO messages (username, postedon, message, acknowledgment)
VALUES (?,?,?,?)
    <sql:param value='<%=request.getParameter("username")%>'/>
    <sql:param value='<%=request.getParameter("date")%>'/>
    <sql:param value='<%=request.getParameter("message1")%>'/>
    <sql:param value='<%=request.getParameter("acknowledgment")%>'/>
</sql:update>
