Registration Page Email Exists?

lukeawade · September 9, 2008

I have a registration page that if all the required fields are filled out then it submits the information to a database and sends them an email. If one of the reqiured fields arent filled out it shows an error message on the same page.

What I'm TRYING to add is a check to see if that email is already in the database or doesnt exist then it shows an error on the same page. WHAT I HAVE WORKING is it checking to see if it exists in the database but it takes you to a blank page with the error message. Please help. My code is below:

<?php require_once('../Connections/connRegistration.php'); ?>

<?php

// Load the common classes

require_once('../includes/common/KT_common.php');

// Load the tNG classes

require_once('../includes/tng/tNG.inc.php');

// Make a transaction dispatcher instance

$tNGs = new tNG_dispatcher("../");

// Make a transaction dispatcher instance

$tNGs = new tNG_dispatcher("");

// Make unified connection variable

$conn_connRegistration = new KT_connection($connRegistration, $database_connRegistration);

// Start trigger

$formValidation = new tNG_FormValidation();

$formValidation->addField("first_name", true, "text", "", "", "", "");

$formValidation->addField("last_name", true, "text", "", "", "", "");

$formValidation->addField("company", true, "text", "", "", "", "");

$formValidation->addField("address1", true, "text", "", "", "", "");

$formValidation->addField("city", true, "text", "", "", "", "");

$formValidation->addField("email", true, "text", "email", "", "", "");

$formValidation->addField("distribution_method", true, "distribution_method", "", "", "", "");

$tNGs->prepareValidation($formValidation);

// End trigger

//start Trigger_SendEmail trigger

//remove this line if you want to edit the code by hand

Please, please wrap your code in BBCode "code" tags so that it prints as code and syntax highlights. I can't fight through this.

Stooney · September 9, 2008

along with using code tags, try to only post the problem area, not all the code you've ever written.

thesaleboat · September 9, 2008

Yeah probably didn't need to see the entire code... but here is code that checks if an email exists in case a user forgets his password it is mailed to them.

<?php
include('dbconnect.php');
$tbl_name="users"; // Table name 
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
// the values sent from form 
$email=$_POST['email'];
$myusername=$_POST['myusername'];

//run query to get password with users inputed info
$emailexists = mysql_query("SELECT * FROM `users` WHERE `users`.`email` = '$email'") or die(mysql_error()); 
$getpassword = mysql_query("SELECT `users`.`password` FROM `users` WHERE `users`.`email` = '$email'") or die(mysql_error()); 

//verify email is actually valid
$email = trim($email);
$_name = "/^[-!#$%&\'*+\\.\/0-9=?A-Z^_`{|}~]+";
$_host = "([-0-9A-Z]+\.)+";
$_tlds = "([0-9A-Z]){2,4}$/i";

//set up mail message
$result = mysql_fetch_assoc($getpassword);
$message = "Hello, ".$myusername.".  Your Password is: ".$result['password'];  //gets the password from the array and displays it 

if(preg_match($_name."@".$_host.$_tlds,$email)){ //verify email is actually valid
     if(!empty($emailexists)){
         if (!empty($myusername) || !empty($email) ) {
          //if it passes all the checks and balances lol 
          $email=$_POST['email'];
          mail($email, "Here is your password", $message , "From: [email protected]"); //Send email to them with variables already set up
          echo "Your password has been sent to your email address, you will be redirected momentarily.";
          echo '<meta content="3; URL=index.php" http-equiv="Refresh" />';// takes you temporarily to another blank page tells the user the password has been sent and then back to index.php
          }//end filled out form check
          else { 
               echo "You did not fill on all required fields."; 
               echo '<meta content="3; URL=forgotpassword.php" http-equiv="Refresh" />';// takes you temporarily to another blank page tells the user they didnt fill in all the fields and then back to forgotpassword.php
          }
     }//end email exists check     
     else { 
          echo "Sorry, your email address was not found in our database."; 
          echo '<meta content="3; URL=forgotpassword.php" http-equiv="Refresh" />';// email not found and then back to forgotpassword.php
     }
}//end proper email validation
else {
     echo "This email address is not in the correct format.";
     echo '<meta content="3; URL=forgotpassword.php" http-equiv="Refresh" />';// incorrect email format msg and then back to forgotpassword.php
}
?>

Hope this helps

Not all the code you've ever written.

Hahahhahahahahahahaha oh man... my co-workers just looked at me like wt eff hahha

lukeawade · September 9, 2008

whats the BBC code tags

thesaleboat · September 9, 2008

when you go to start a new discussion on the top of the page you will see a lot of little icons (dont worry they yelled at me at first too when i first started posting) and if you press the one with the # it will give you this little

<?php is so cool ?>

just put your code in between there and it'll look all pretty then did what i post help?

lukeawade · September 9, 2008

Kind of. Im just checking to see if the email exists in this list I have in my database and that actually works. I just cant get it to display under my email box. Currently if they dont put an email and click submit then it shows an error. The code below is what I use to check if their email has already been put in the database. Only problem is if their email already exists it takes me to a blank page and just says my error message. "'ERROR! The email '.$_POST['email'].' has already registered." I want it to display this message below my email text field.

<?php //my email check above the body & head 
//checks if the email is registered
if (!get_magic_quotes_gpc()) {$_POST['email'] = addslashes($_POST['email']);}
$usercheck = $_POST['email'];
$check = mysql_query("SELECT email FROM dashboard_registration WHERE email = '$usercheck'") or die(mysql_error());
$check2 = mysql_num_rows($check);
//if the name exists it gives an error
if ($check2 != 0) {die ('ERROR! The email '.$_POST['email'].' has already registered.');}

//my text field in a table in the body
<input name="email" type="text" id="email" value="<?php echo $row_rsdashboard_registration['email']; ?>" size="32" />
				    <?php echo $tNGs->displayFieldError("dashboard_registration", "email"); ?>

thesaleboat · September 9, 2008

Here try this instead of die... and change the index.php page to wherever you want it to redirect to after you show them the error. you can change the 3 to less (3 is the time it spends before redirecting)


//if the name exists it gives an error
if ($check2 != 0) {
    echo "Sorry, your email address has already been registered."; 
    echo '<meta content="3; URL=index.php" http-equiv="Refresh" />';// where index.php is the page you want it to go back to after you show the email

}

lukeawade · September 9, 2008

echo doesnt work. I have my page redirecting to a thank for registering page and echo doesnt work for some reason. I put in an email that is already in the database and it just redirects me to the next page with no error

thesaleboat · September 9, 2008

hmm... are you having the form post to itself? if so you could try and change the form's action to action="checkemail.php" and have all of your checks and code within the checkemail.php and then echo would work and you could redirect them back to the registration page with the echo '<meta...

lukeawade · September 9, 2008

currently I have a trigger sending it to the next page.

<form method="post" id="form1" action="<?php echo KT_escapeAttribute(KT_getFullUri()); ?>">

thesaleboat · September 9, 2008

Does your page have a black background?

echo '<font color="red">"Sorry this email address is already registered."</font>';

thesaleboat · September 9, 2008

If this doesn't work, my next suggestion is to start a new topic with a more focused question and only a segment of code and get some of the experts to take a look at it.

lukeawade · September 9, 2008

no my page doesnt have a black background and it wouldnt matter if it did because it redirects to another page.

How do i get experts to look at it?

thesaleboat · September 9, 2008

start a new topic with only a section of code so they will actually look at it... sorry i couldn't help man ??? :-\

best of luck im out for the day
