Setting Session Variables and Calculating from other .php files

Question

I am trying to use php to set session variables on the initial loginPage.php and show up on the paymentPage.php but I am having troubles setting the $_SESSION variables so that it shows up. There is a web page in between the loginPage and the paymentPage and that seems to be tripping me up.

Also, I need to calculate a total of the selected items on the previous page but I am unsure how put a dollar amount with a checkbox that does not show but calculates the total on the paymentPage.

loginPage.php

<?php

    session_start();

?>

<html>

<head>

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

  <title>Form Login</title>

<body OnLoad="document.main.username.focus();">

  <table>

    <tr>

      <td colspan="2">

        <h2>Welcome to the Equine Shop!</h2>

        <h4>Please enter a personalized Username, Email Address and Password to continue to our online store</h4>

      </td>

    </tr>

    <!-- create the main form with an input text box named uid and a password text box named mypassword -->

    <form name="main" method="post" action="EquineShop.php">

        <tr>

          <td>Email Address:</td>

        <tr>

          <td><input type="password" name="pass" type="text" size="50"></td>

Look I really looked through your code and I don't know if there's something missing but I doesn't make too much sense for me. Anyway if it works for you it's fine.

Here's a Typo that I found:

paymentPage.php

echo "<tr>
        <td>" . $_SESSION['username'] . "</td>
        <td>" . $_SESSION['emailadd'] . "</td>
     </tr>";

And for your calculation.. I don't know man. You made the dom a little bit to static to get these values foreach product or whatever. The best thing you can do is to give every element a unique Id oder class and than validate it via JS to see if it got checkt or not. There's still a long way for you.. But remember we don't write your code.

I appreciate your honesty, I am very new to this as I have never worked with HTML or PHP before. I will take your suggestions and see what I can come up with! I wasn't expecting you to give me code, just some pointers on what I need to improve and what you think of my problems. Thank you!

You forgot to ask a question and to explain your problem.

Any page which is accessing the session must(1) start with a PHP block containing session_start(). Only 1 of the the 4 scripts you've shown us does this.

1) Not strictly true - but a discussion of the exceptions is too complex to go into here

Ok, so every single page needs to contain session_start() in order for the variables to be passed to other pages? I will work on that to correct my issue. I guess my questions were 1) why are my variables not being passed to the other pages and 2) in word form, how should I go about getting a total dollar amount on the paymentPage.php from the EquineShop.php page. Not looking for code, but I can't seem to wrap my head around it. Thank you for your help!

Another problem i found is on your thankyou page:

<form name="main" method="post" action="loginPage.php">
  <input type="submit" value="Log Out" />
  <?php
    session_unset();
    session_destroy();
?>
</form>

What I think you are trying to do: You are trying to make a form that removes all your session variables when you click the submit button.

What you are actually doing:

You are rendering a form that on submit wil send a POST to loginPage.php. and while you are building this form on the server you are also already unsetting the Session variables. As the code above equals the code i show you here below:

<?php //deleting session state
    session_unset();
    session_destroy();
 //now lets output some html, being a form:
?>    
<form name="main" method="post" action="loginPage.php">
  <input type="submit" value="Log Out" />
</form>
