I have the form up, but when I type something in and submit it it just refreshes the page. I'm not entirely sure how to use render and redirect so it's a bit of guess work, but no luck.

The controller is quote.php, the form is quote_form.php, and the template for displaying the quote is quote_template.php. My code is below:




I've struggled a lot with the material for this problem set. Watched the lectures twice and watched the walkthroughs and sections several times. Any help would be much appreciated.

You definitely don't need to do this:


... after you have used the render() function.


For quote.php, you should be doing something like this (in pseudo-code):


    // configuration

    // if user reached page via GET (as by clicking a link or via redirect)

        // else render form

    // else if user reached page via POST (as by submitting a form via POST)

        // validate submission
        // if symbol not in $_POST, apologize

        // Look up that stock

        // if symbol not found, apologize

        // else render quote

You should look at the distribution code provided by CS50 Staff in the pset7.zip archive, and pay special attention to the parts that have comments like those in my pseudo-code above, especially the sections relating to // configuration, // if user reached page via GET, and // if user reached page via POST.


Here's your problem: You need to use <form action="quote.php" method="post"> in your quote_form.php View. You can't use method="get", and here is why. When the quote.php Controller is reached via GET, it will render the quote_form.php View. That's why your code appears to just be refreshing the page. You want it to render the quote_template.php View instead, but only if it is responding to a form submission.

  • Ok thanks. I didn't have that originally and added it because my page wouldn't redirect. I can remove it but the code still doesn't work.

    I don't condition on GET or POST because my form only submits vie get, so it seems unnecessary. As far as I know I do follow that pseudo code though.
