[SOLVED] Putting form error messages into a list

[AdRock]

I have some form validation and I want to put all the error messages that are displayed into a bulleted list.

 

I have seen it done with more complicated validation using OOP but I don't know enough to do that.

 

How would I add these error messages to a list if they occur?

 

if(empty($first_name)) { 
        $error['first_name'] = true; 
         $print_again = true; 
        $message="The forename field is empty<br />"; 
    }
    else if(!ereg("^[A-Za-z]{2,30}$",$first_name)) {
$error['first_name'] = true; 
         $print_again = true; 
        $message="Forename must contain letters only<br />";
    }

    if(empty($last_name)) { 
        $error['last_name'] = true; 
         $print_again = true; 
        $message.="The surname field is empty<br />"; 
    }
    else if(!ereg("^[A-Za-z\-]{2,30}$",$last_name)) {
$error['last_name'] = true; 
         $print_again = true; 
        $message.="Surname must contain letters only<br />";
    }

    if(empty($email)) { 
        $error['email'] = true; 
         $print_again = true; 
        $message.="The email field is empty<br />"; 
    }
    if( mysql_num_rows(mysql_query("SELECT email_address FROM users WHERE email_address = '$email'")) ) {
$error['email'] = true; 
         $print_again = true; 
        $message.="Your email address has already been used by another member in our database. Please submit a different Email address!!<br />"; 
    }
    else if(!check_email_address($email)) { 
        $error['email'] = true; 
         $print_again = true; 
        $message.="Email address in invalid format<br />"; 
    } 
    
    if(empty($username)) { 
        $error['username'] = true; 
         $print_again = true; 
        $message.="The username field is empty<br />"; 
    }
    else if( mysql_num_rows(mysql_query("SELECT username FROM users WHERE username = '$username'")) ) {
        $error['username'] = true; 
         $print_again = true; 
        $message.="The username you have selected has already been used by another member in our database. Please choose a different Username!<br />";
}
    else if(!ereg("^[A-Za-z0-9\-]{3,30}$",$username)) {
$error['username'] = true; 
         $print_again = true; 
        $message.="Username must contain letters and numbers only<br />";
    }  

    if(empty($password1)) { 
        $error['password1'] = true; 
         $print_again = true; 
        $message.="The password field is empty<br />"; 
    }
    else if(!ereg("^[A-Za-z0-9]{6,30}$",$password1)) {
$error['password1'] = true; 
         $print_again = true; 
        $message.="Password must contain letters and numbers only<br />";
    }  

    if (strcmp( $password1,$password2 ) !=0){
$error['password1'] = true; 
$error['password2'] = true; 
         $print_again = true; 
        $message.="The passwords didn't match<br />";
    }

    if (empty($_POST['verify']) && $_POST['verify'] == $_SESSION['captchstr']) {
$error['verify'] = true;
$error['password1'] = true;
$error['password2'] = true; 
         $print_again = true; 
        $message.="Please enter Anti-Spam key<br />";
    }

 

I use this bit to redisplay the form and display the error messages

 

    if($print_again) {
echo "<h2 class=\"errorhead\">There has been an error:</h2><p>You forgot to enter the following field(s)</p>$message";
        show_form(); 

        } else {

I did an example with the first two possible error outputs for you:

 

<?php

if(empty($first_name)) { 
        $error['first_name'] = true; 
         $print_again = true; 
        $message .="<li>The forename field is empty</li>"; 
} else if(!ereg("^[A-Za-z]{2,30}$",$first_name)) {
$error['first_name'] = true; 
         $print_again = true; 
        $message .="<li>Forename must contain letters only</li>";
}
    
?>

 

And with the snippet of code that displays the errors, just do this:

<?php

if($print_again) {
   echo "<h2 class=\"errorhead\">There has been an error:</h2><p>You forgot to enter the following field(s)</p>
   <ul>$message</ul>";
   show_form(); 
} else {
  
?>
