Default My solution to exercise 6, on ch.2 - help

Hi all,

When trying to solve ex. 6, of chapter 2 (p. 82), I got this solution, which I expected to work, but it doesn't. The number of visits is always "1", no matter how many times I access the page.
Can anyone tell me what am I doing wrong?

The code follows:

- file ch2ex4.php:

<?php

setcookie('remember', time()+600);

?>
<html>
<head>
<title>Text formatter</title>
<?php

?>
</head>

<body>
<form method="post" action="ch2ex4_1.php">
  <p>Enter your text:
    <input type="textarea" name="sentence">
  </p>
  <p>Enter color for text:
  </p>
  <p>Black:
    <INPUT TYPE="radio" name="color" value="black">
  </p>
  <p>Red:
    <INPUT TYPE="radio" name="color" value="red">
  </p>
  <p>Do you want to save these preferences for the next time you log in?
    <input type="checkbox" name="pref" value="y">
  </p>
    <input type="submit" name="Submit" value="Submit">
  </p>
</form>
</body>
</html>


... and ch2ex4_1.php:


<?php
session_start();
setcookie('count', time()+60*60*24);
if ($_POST['pref']=='y') {
setcookie('font', $_POST['font'], time()+60);
setcookie('size', $_POST['size'], time()+60);
setcookie('color', $_POST['color'], time ()+60);
}
?>
<html>
<head>
<title>Formated text: </title>
</head>

<body>
<?php
//echo "";
//echo $_POST[sentence];
//echo "";

function counter() {
    $count=$count+1;
    echo "&nbsp;";
    echo "This is your visit number ";
    echo $count;
}

echo "" . $_POST[sentence] . "";

counter();

?>


</body>
</html>

Default Session Variables

Hey,
you have to use a $_SESSION variable to hold the page count.
I suppose after your user is done you can increment the session var to a cookie for future use.
Try this for the page counter:
Code:
<?php
session_start();  
if(isset($_SESSION['views']))
    $_SESSION['views'] = $_SESSION['views']+ 1;
else
    $_SESSION['views'] = 1;

echo "views = ". $_SESSION['views']; 
?>
<html><head><title>Formated text: </title></head>
<body>
<p>This is visit number: <?php echo $_SESSION['views']; ?></p>
</body>
</html>
