    This is my first post so please excuse me if I am not observing
    protocol.
    I have a zencart dynamic site with a few static pages. I want to
    increase the non-dynamic pages by adding extra content pulled from the
    catalog (mainly images, prices, "add to cart" etc) that is in the
    dynamic area of the site on my server. I am not advanced enough to
    script this personally (and too old to learn), and the 3500 products
    change too often for me to even contemplate doing this manually. I
    would be grateful if anyone can point me in the right direction to do
    this.Thanks in advance
    Rob

    In which way the browser will understand the PHP code. As becz the PHP
    code will be compiled at server itself.

    PHP (like ASP, JSP, cold fusion etc) is a sever side language, the browser
    does not deal with it.
     
    When a user is on a website, he/she clicks on a link requesting a page. The
    request is sent from the browser to the server. If the page uses PHP then
    the server execute the script (which generally communicates with a database
    or compile the HTML returns) and generates an HTML page which is sent to the
    browser.
     
    That's the beauty of server side scripting, you don't have to worry about
    what type of browser is used.
     
    Hope this answers your query

    do you have WAMP installed? use that as a local server to test php scripts
    locally.

    Hi all I hope there are some PHP wizards here as im stuck. Im learning
    php threw a book but thought I would try make something by myself to
    learn more.
     
    I decided to make a simple banking script which shows your balance
    which starts at zero. I have an input where you put the amount you
    want to deposit then I add the deposit variable to the balance
    variable then echo balance which should show the amount you deposited
    but for some reason $deposit + $balance is not working.
     
    Can any one help please :)
     
    <!doctype>
    <html>
    <head>
    <title>PHP test</title>
    </head>
    <body>
    <h1>Piggy Bank</h1>
    <?php
    $balance = 0.00;
     
    if (isset($_POST['submitted'])) {
     
    $deposit = $_POST['deposit'];
     
    number_format($deposit) + $balance;
    }
     
     
    echo $deposit; // checking to see I am getting the data from the input
    ?>
    <form action="index.php" method="post">
    <p>Deposit: <input type="text" name="deposit" /><input type="submit"
    value="deposit" /></p>
    <input type="hidden" name="submitted" value="TRUE" />
    </form>
     
    <p>Balance:<?php echo "£" . number_format($balance); ?> </p>
    </body>
    </html>

    you are not assigning this to any variable:
    number_format($deposit) + $balance;
     
    shouldn't it be $balance = number_format($deposit) + $balance;

    yeah that works but its not adding the balance to the new deposit amount it
    just displays the deposit amount.
     
    Thanks

    do you think it could be because im resetting $balance at the top of the
    script? $balance = 0.00;
     

     

    Olivier Florence <oli.florence@gmail.com> Sep 22 10:08AM +0100 ^
     
    $balance is a variable so it is resets eveytime the page is refresh and
    submitting the form will refresh the page so your script will always take
    what ever is passed on by the form and add 0 to it.
     
    If you want to add to a new balance every time then that balance has to be
    stored somewhere, in a database would seem the logical thing. For the
    purpose of the exercise you could store the balance in a cookie or pass the
    new balance to a form field and instead of reset $balance to 0 you collect
    it from the form

    the easiest is to the form (note this is just for the test you are doing,
    this is not reliable or safe if you were to do anything financial)
     
    Just set a form field called balance, feed it with your php variable
    balance. Set that variable to 0 if the form is not submitted and to the form
    post if the form is submitted, you are already doing this for your other
    post variable

    setcookie("balance",<the value as string>);
     
    When received:
     
    if (isset($_COOKIE("balance")){
    $balance = $_COOKIE['balance'];
    }
    ...
     
    This should serve your purpose
