Use html placeholder attributes.

 

Give your topics meaningful titles.

 

Use code tags when posting code.

You're talking to a signature, brah.

Put the error messages in an array. At the moment, if there is more than one error, only the last is returned.

 

And who said anything about sql?

[Rubendo]

Barand i want to put in div firstname <?php echo "$errors" ?> but this $errors is not difined

 

[Barand]

Your variable is $error, not $errors

[Rubendo]

yes its word wrong but how can i put ander field ?? my function returned $error and then i do $error = function "for axample dod"

 but then what can i  do

You can do something like this:

<?php
if (isset($_POST['submit'])) {
    function validate($key, $value)
    {
        $error = array();
        switch ($key) {
            case 'firstname':
                $error[$key] = (empty($value)) ? 'Putt Your Firstname' : '';
                break;
            case 'lastname' :
                $error[$key] = (empty($value)) ? 'Putt Your Lastname'  : '';
                break;
            //...
        }
        return $error;
    }
 
    // $arr = array('firstname', 'lastname', 'email', 'pass', 'confirmpass');
 
    foreach ($_POST as $key => $value) {
        $error = validate($key, $value);
        echo $error[$key];
    }
}
?>

The above code uses the ternary operator. More information can be found here:

Side note: Put is spelled with one (1) "t". "Putt" is something else.
