    Order Processing Page

    Hi All,

    I have an assignment to complete and I just can't get it and I was hoping someone could help me out. What I need to do is:

    Call the session_start function.

    Code:
    <?php
session_start();
?>
    Detect whether or not the name session variable has a value; if so, display name and age as text; if not, display the name and age input fields.

    Code:
    First name: <input type="text" name="fname" />  Age: <input type="text" name="age" />  <input type="submit" name="submit" value="Submit" />

<?php
if (isset($_POST['submit'])) { 
$_session['fname'] = $_POST['fname'];
$_session['age'] = $_POST['age'];
} 
?>
    How can have the text fields replaced with the users Name and age after they type it in and submit the form? So, when they go back to the that page, they will already see their name and age printed out in place of the text fields. I also upload an image of what it is suppose to look like.

    Thanks in advance for your help,
    T

      Your fields and button must be placed inside the form tag. (<form method="post"> fields here!.. </form>)

      Try to run this codes. . .
      Code:
      <?php 
session_start();
ob_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Sample</title>
</head>

<body>

<form method="post">
	First name: <input type="text" name="fname" />  Age: <input type="text" name="age" />  <input type="submit" name="submit" value="Submit" />
</form>

</body>
</html>
<?php 
	if(isset($_POST['submit']))
	{
		$_SESSION['fname']=$_POST['fname'];
		$_SESSION['age']=$_POST['age'];
		//header('Location: page_to_go.php');
		echo $_SESSION['fname'].' '.$_SESSION['age'];
	}
?>

          Hi Exequiel,

          Thank you for the reply. I tried the code you suggested and it still doesn't work. Here's what I have:

          Code:
          <?php 
session_start();
ob_start();
?>

<?php echo '<?xml version="1.0" encoding="IUTF-8"?>'; ?>

              You need to first check whether or not the name variable in the session is set and then choose what to output depending on if it's set or not.

                  If there's a session started, I need to have their name (fname) and age (age) displayed where the input text fields should be. If the session is not started, then the whole form should display with text fields for the user's input. Would it look something like this:

                  Code:
                  <?php 
    if(isset($_POST['submit']))
    {
        $_SESSION['fname']=$_POST['fname'];
        $_SESSION['age']=$_POST['age'];
        //header('Location: catalog.php');
        echo $_SESSION['fname'].' '.$_SESSION['age'];
    }
    if (isset($_POST['fname']) && ($_POST['age']))
             $session = $_POST['fname'] && $_POST['age'];
     session_start();
     $_SESSION['fname'] && $_SESSION['age'] = $session;
?>
                  I'm sorry if this isn't close. I'm not a very good programmer and I'm still trying to learn.

                  Thanks,
                  T

                      It needs to look more like this
                      Code:
                      <?php 
if(isset($_POST['submit'])) {
   set your session variables
   output your values
} else {
   output your form
}
?>

                          I tried this:

                          Code:
                          <form id="frm1" name="myForm" onsubmit="return (validateForm() && checkRadios())" action="thankyou.php" method="post">
<?php 
    if(isset($_POST['submit'])) {

$_SESSION['fname']=$_POST['fname'];
$_SESSION['age']=$_POST['age'];
     
    if(isset($_SESSION['fname'])) {
      //header('Location: catalog.php');
      echo $_SESSION['fname'].' '.$_SESSION['age'];}
    else {
echo 'First name: <input type="text" name="fname" />  Age: <input type="text" name="age" />  '; }
}
?>
<input type="submit" value="Submit" /> <input type="button" onclick="formReset()" value="Reset form" />
                          It's not displaying the text fields or the output. Am I getting close?

                              That structure doesn't follow my example.

                                  Ok, so what am I doing wrong? Please remember I trying to learn this. I very green when it comes to programming. Should it look like this:

                                  Code:
                                  <?php 
    if(isset($_POST['submit'])) {

$_SESSION['fname']=$_POST['fname'];
$_SESSION['age']=$_POST['age'];
     
    if(isset($_SESSION['fname'])) {
      //header('Location: catalog.php');
      echo $_SESSION['fname'].' '.$_SESSION['age'];}
    else {
echo '<form id="frm1" name="myForm" onsubmit="return (validateForm() && checkRadios())" action="thankyou.php" method="post"> 

First name: <input type="text" name="fname" />  Age: <input type="text" name="age" /> <input type="submit" value="Submit" /> 

<input type="button" onclick="formReset()" value="Reset form" />'; }
}
?>

                                      Compare your structure to my structure.

                                      To repeat, my structure is this:
                                      Code:
                                      <?php 
if(isset($_POST['submit'])) {
   set your session variables
   output your values
} else {
   output your form
}
?>
                                      Your structure is this:
                                      Code:
                                      <?php 
if(isset($_POST['submit'])) {
   set your session variables

   if(isset($_SESSION['fname'])) {
      output your values
   } else {
      output your form
   }
}
?>
                                      As your can see, your structure is not the same as mine.

                                          So from what you said above, it should look like this?

                                          Code:
                                          <?php 
    if(isset($_POST['submit'])) {
$_SESSION['fname']=$_POST['fname'];
$_SESSION['age']=$_POST['age'];
//header('Location: catalog.php');
echo $_SESSION['fname'].' '.$_SESSION['age'];}
    else {
<form id="frm1" name="myForm" onsubmit="return (validateForm() && checkRadios())" action="thankyou.php" method="post"> First name: <input type="text" name="fname" /> Age: <input type="text" name="age" /> <input type="submit" value="Submit" /> <input type="button" onclick="formReset()" value="Reset form" />';
}
?>

                                              That looks about right.

                                              But I see another error, you didn't give your submit button a name. So it's not going to be set when it goes to check it.

                                                  Ok, I just tried the code above and it still doesn't show the name and age in replace of the text fields after the I go back to my catalog page. This is what I have:

                                                  Code:
                                                  <?php 
    if(isset($_POST['submit'])) {
$_SESSION['fname']=$_POST['fname'];
$_SESSION['age']=$_POST['age'];
echo $_SESSION['fname'].' '.$_SESSION['age'];}
    else {
echo '<form id="frm1" name="myForm" onsubmit="return (validateForm() && checkRadios())" action="thankyou.php" method="post">';

echo 'Age: <input type="text" name="age" />';
echo '<input type="submit" name="submit" value="Submit" />';

}

                                                  I really do appreciate your help with this.

                                                      Works fine for me.

                                                      Assuming of course that everything else is correct. I am assuming all the code before and after this block of code is correct and that this code is in fact in the thankyou.php page. By which I mean you're submitting the page to itself.

                                                      And if by going back, you mean clicking the back button on your browser, that doesn't refresh the page.

                                                          Its not still working because of the action on your form, action="thankyo u.php". Your code that you replied to me is right, only the thankyou.php is the problem. If you try to remove the action="thankyo u.php" on your form the code is working fine. but if you really want to display the session on thankyou.php try my code. I've created thankyou.php. can you post your thakyou.php ?
                                                          Code:
                                                          <?php 
session_start();
ob_start();
?>

<?php 
	echo $_SESSION['fname'].' '.$_SESSION['age'];
?>
