Setting the cookie using form values...

[suttercain]

Good day to everyone,

 

I am taking a php class and have a homework assignment. The teacher wants us to

 

1. Have a form.

2. Validate the form.

3. If validated set a cookie using the form inputs as values.

 

I am stuck on step three.

 

Here is the code I am using, all within one page (I like PHP_SELF for some reason).

 

Code:

<?php
$value = array('$year', '$miles', '$colour', '$model');
setcookie("automobile", $value, time()+3600);

if(isset($_POST['submit'])){ // If the form was submitted
     validate(); // Check for empty fields
     if(count($errors) != 0){ // If there are errors, let the user know.
      	show_form();// redisplay the form
     } else { 

 move_on(); } // After the user submits the form, if validated, will check the cookie status
   }
   else{show_form();}

function move_on() {
if (isset($_COOKIE['automobile'])) {
       print_r ($_COOKIE);
echo "Cookie is set!";
	} else {
echo "Cookie is not set!";
	}
}

function validate() {
global $errors;
	if ($_POST['year'] == "" || !preg_match('/\d{4}/',$_POST['year'])) {
	$errors['year']="<font color='red'>* Please enter a four digit year.</font>";
	}
	if ($_POST['miles'] == "") {
	$errors['miles']="<font color='red'>*</font>";
	}
	if ($_POST['colour'] == "") {
	$errors['colour']="<font color='red'>*</font>";
	}
	if ($_POST['model'] == "") {
	$errors['model']="<font color='red'>*</font>";
			} 
	}

//If the first time view the page or if there are errors
function show_form() {
global $errors;
?>

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
Year:<?php echo $errors['year']; ?><br />
<input name="year" type="text" value="<?php echo $_POST['$year']; ?>" size="4" maxlength="4" />
<br /><br />
Miles:<?php echo $errors['miles']; ?><br />
<input name="miles" type="text" value="<?php echo $_POST['miles']; ?>" size="6" maxlength="6" />
<br /><br />
Colour:<?php echo $errors['colour']; ?><br />
<input name="colour" type="text" value="<?php echo $_POST['colour']; ?>" size="12" maxlength="12" />
<br /><br />
Model:<?php echo $errors['model']; ?><br />
<input name="model" type="text" value="<?php echo $_POST['model']; ?>" size="20" maxlength="20" />
<br /><br />
<input type="submit" name="submit" />
</form>
<?php
}
?>

 

When I check if the cookie is set, I get that it isn't. I am not sure how or why it is not set.

 

Any suggestions? Thanks.

What is the error your getting?

 

Just looking at your code, you do not set $value up as anything...I dont know if your passing it from another page or what, but $value is not set as variable, so essentially your cookie has no data..

I thought I had set it here:

$value = array('$year', '$miles', '$colour', '$model');

 

Or do I need to assign a variable to $year, etc.. like so

$year= $_POST['year'];

 

?

In that code those values arnt specified as anything, if your submitting the form to itself you need to do like $year=$_POST['year'];......I am not that familiar with cookies, but can you set it as an array? I think you need a single cookie for each value or insert each value seperatly in the same cookie...try inserting each value seperatly in the cookie with multiple setcookie() commands...
