You definitely don't need to do this:
... after you have used the
quote.php, you should be doing something like this (in pseudo-code):
// 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
// 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.
