Question

Below is my code for a simple form in the create_session.php page. I am using the forma action method to navigate the user to the “QandATable.php” page when the user submits the form. But what I want is that if the user types in the number 1 in the number of sessions textbox, then navigate to the QandATable.php page wheh the user submits the form, else if it is any other number, then when the user submits the form, I want it to go back to the “create_session.php” (Back to its own page). Imagine it like you click on the submit button and it refreshes the page so it goes back to being a blank form, thats what I want to do if the number of sessions textbox contains a number which is bigger than ‘1’. How can this be done? I am using php and jquery code as well as basic html.

Thank You

 <form action="QandATable.php" method="post" id="sessionForm">
      <p><strong>Number of Sessions you Require:</strong> <input type="text" id="sessionNo" name="sessionNum" onkeypress="return isNumberKey(event)" maxlength="5" /></p>
        <p><input class="questionBtn" type="submit" value="Prepare Questions" name="prequestion" onClick="myClickHandler(); return false;"/></p>      <!-- Prepare Questions here-->

    </form>

At the very top of the QandATable.php script add:

if ($_POST['sessionNum']!=1) {
  header("Location: create_session.php");
  exit();
}

But as others have mentioned in the comments, you might as well just make the form submit to the create_session.php page and if it’s successful then redirect to the next page.
