<?php 
function show_register()
{
$error_string = '';
echo '<form id="loginform" method="post" action="">
    <fieldset>
        <legend>

            <input name="submit" id="submit" tabindex="4" value="Log in" type="submit">
        </label>
    </fieldset>
</form>';
}

if(isset($_POST['submit']))
{
$errors = array();
$valid = 0;
if(empty($_POST['username']))
{
	$valid = 1;
	$errors['username'] = "Empty Username Field";
}
if(count($errors) > 0) 
{
	global $error_string;
      $error_string = implode('</li><li>', $errors);
      $error_string = "
        <div class='form_errors'>
          The following errors were encountered while processing your request:
          <ul><li>{$error_string}</li></ul>
        </div>
      ";
	show_register($errors);
}
else
{
	processform();
}

} else
{
show_register();
}

function processform()
{
echo "Registered";
}
?>

ok where i have if(count($errors) > 0 .. i would like that output to be inside the form after validation but i`m a little tired and i'm escaping something in the logical part. i would require some assistance.

function show_register()
{
  $error_string = '';
  echo '<

 

should be

 

function show_register($error_string='')
{
  echo '<

Two things for one, inside of the show_register() function you set $error_string to = ''; which is no good, it will always equal nothing. Second you did not build the function to accept variables, so it will not use them. you need to start it like this.

 <?php
function show_register($errors){
    if(!isset($errors)){
        $error_string='';
    }
    else{
        $error_string=$errors;
    }
//etc.
?>
