[SOLVED] A better way to write this script??

farkewie · November 4, 2007

Hello,

i am trying o write a register script here are the features im trying to get working

#confirm password

#check each field is filled out

#display all errors in a message box

#leaving fields populated when gets errors

i have all of that working but im thingking when it does get anerror its going to still insert in to the database and email user because there iss no "die;" or "exit;" after the error

but if i put them in the form doesnt display again

and if i add the php below the html the message doesnt display??

any ideas?

<?php 


include ("sql.php");


$user_name = $_POST['user_name'];
$user_password = $_POST['user_password'];
$user_password2 = $_POST['user_password2'];
$user_firstname = $_POST['user_firstname'];
$user_lastname = $_POST['user_lastname'];
$user_email = $_POST['user_email'];
$form_name = $_POST['form_name'];
$confirmkey =  md5(uniqid(rand()))



//check if username exists
mysql_select_db("tyspicsc_albumv1", $sqlconnection);
$check = "SELECT * FROM users WHERE user_name='$user_name'";
$check = mysql_query($check);
$check_row = mysql_fetch_assoc($check);

$check = $check_row['user_name'];   

echo  $check ;



if ($form_name == "register_form") {


//make sure all the field are fill out correctly

	if (empty($user_name)) {
		$message = "Please fill out Username!";
		header('Location: '.$_SERVER['HTTP_REFERER'].$_SERVER['QUERY_STRING']);
		exit;
	}
	if (empty($user_password)) {
		$message = "Please fill out Password!";
	}
	if (empty($user_password2)) {
		$message = "Please Confirm Password!";
	}
	if (empty($user_firstname)) {
		$message = "Please fill out First Name!";
	}
	if (empty($user_lastname)) {
		$message = "Please fill out Last Name!";
	}
	if (empty($user_email)) {
		$message = "Please fill out Email!";
	}		
	if (isset($check)) {
		$message = "Username already taken! <a href=\"pwremind.php\">Click Here</a> if you have forgotten your password.";

	}
	if ($user_password !== $user_password2) {
		$message =  "Passwords do not match!!";
	}
	else { 
		$user_password = md5($user_password);	
	}

what I'd do, is make a page called page_fns.php, and then have:

<?php
function doForm(){
?>
ANY HTML YOU WANT IN THE FORM (php works aswell)
<?php
}
?>

Then, whenever you want the form, put doForm(); So then, you can exit(); and stuff.

<?php

if (empty($user_name)) {
		$message = "Please fill out Username!";
		doForm();
		exit;
	}
	if (empty($user_password)) {
                        doForm();
		$message = "Please fill out Password!";
		exit;
	}
	if (empty($user_password2)) {
                        doForm();
		$message = "Please Confirm Password!";
		exit;
	}
	if (empty($user_firstname)) {
                        doForm();
		$message = "Please fill out First Name!";
		exit;
	}
	if (empty($user_lastname)) {
                        doForm();
		$message = "Please fill out Last Name!";
		exit;
	}
	if (empty($user_email)) {
                        doForm();
		$message = "Please fill out Email!";
		exit;
	}		
	if (isset($check)) {
                        doForm();
		$message = "Username already taken! <a href=\"pwremind.php\">Click Here</a> if you have forgotten your password.";
		exit;
	}
	if ($user_password !== $user_password2) {
                        doForm();
		$message =  "Passwords do not match!!";
		exit;
	}
	else { 
		$user_password = md5($user_password);	
	}

Change the function form() to function form($message). Then when you want the message, don't put:

<?php if (isset($message)){?>
</p>
<table width="468" border="1" align="center">
  <tr>
    <td class="aaa">Message</td>
  </tr>
  <tr>
    <td class="errortext"><?php echo $message ?></td>
  </tr>
</table>
<?php } ?>

put

<?php if ($message != ''){?>
</p>
<table width="468" border="1" align="center">
  <tr>
    <td class="aaa">Message</td>
  </tr>
  <tr>
    <td class="errortext"><?php echo $message ?></td>
  </tr>
</table>
<?php } ?>

So when you call the function, say,

<?php
if (empty($user_email)) {
		$message = "Please fill out Email!";
		form($message);
		exit;
	}		
?>

if there is no message, just put form('');
