1. There is a spelling mistake in your code.
check for the spelling of $oaky and not $okay

2. if (empty($_POST['variable'])) works, but that's assuming the variable exists.
Try this:

Code: Select all: if (isset($_POST['variable']) && !empty($_POST['variable'])) { $okay = FALSE; echo '<p> OOps.. Variable isn\'t defined or is empty</p>'; $array[$_POST['variable']] = 0; } else { $array[$_POST['variable']] = 1; } // for giggles.. echo '<pre>'; print_r($array); echo </pre>; //

i want a code which matches the password fields like as in
password:
confirm password:

if ($_POST ['password'] != $_POST ['confirm']){
print '<p class="error">your password does not match..</p>';
$okay=false;
}

is this code correct for password matching??

I want a Ferrari California for less than 150k too, but I wont' get one.

Yes, assuming that your variables are defined as such.

<input type="password" name="password" value="">
<input type="password" name="confirm" value="">

then

if ($_POST['password'] !== $_POST['confirm']) {
echo "Passwords don't match. Please insert coin to continue.";
}

step 1.
Drink something cold and refreshing.

step 2.
Slow down Kemosawbi..

step 3.
When the form is entered properly, it says.. Done.
Isn't that what you wanted?

step 4.
I told you that using empty() is a BAD idea, apparently listening to advice isn't your best quality.

step 5.
redo all of your empty statements to reflect the following:

if ($_POST['variable'] == '' || strlen($_POST['variable']) <= 2) {
echo "Oops, This cannot be blank or longer than 2 characters (variable is: $_POST[variable])<br>";
}

MMkay?

Try this: (and donate $5.00 to a local charity or to your favorite Rotweiller Shelter)

Code: Select all: <html> <head> <title> Form </title> <style type="text/css"> .error{color:red; font-family:verdana; font-size:16px;} </style> </head> <body> <?php if ($_POST['name'] == '' || strlen($_POST['name']) <= 2) { $error['NAME'] = "Name cannot be blank. Please enter a valid name."; } if ($_POST['email'] == '' || strlen($_POST['email']) <= 2) { $error['EMAIL'] = "Email is not valid. (Although I should use better email validation)"; } if (strlen($_POST['password']) <= 5) { $error['PASSWORD'] = 'Password is too short. Please try again'; } elseif ($_POST['password'] !== $_POST['confirm']) { $error['PASSWORD'] = 'Passwords do not match. Please try again!'; } if (!isset($error)) { echo "Hurray! We have a completed form!"; } else { foreach($error as $k => $v) { echo '<p>'.$v.'</p>'; } } ?> </body> </html>

what troubled me this time around is cookies......i understood its meaning n what does it do.....
but this line:
if(isset($msg)
is making me confused....as far as i knw the isset function is used to check wether the form is submitted or not...now then y is ($msg) is in parenthesis...wat does this line actually mean??will it check wether $msg value is submitted or not,or what will it do???i have not given any button or submit values $msg in the below code....kindly tell me what does this line actually does...

<?php
if(isset($_POST['submitted'])){
setcookie('font_size',$_POST['font_size']);
setcookie('font_color',$_POST['font_color']);
$msg = '<p>Your settings have been entered...click <a href="view.php">HERE</a>to
see them in action.</p>';
}
?>
<html>
<head>
<title>
CUSTOMIZE YOUR SETTINGS
</title>
</head>
<body>
<?php
if(isset($msg)){
print $msg;
}
?>

pls help.....

"isset" only determines if a variable is set and it's not NULL. It has nothing to do with cookies . in your code it's just checking if the $msg variable has a value and if yes, it will be printed. and of course the $msg variable is set in this line :
$msg = '<p>Your settings have been entered...click <a href="view.php">HERE</a>to
see them in action.</p>';

You are easy to check validation of your website. You are upload your website in w3validator. It gives the all error in your html. It is easy to way to solve your problem.
