Check if user is registered before inviting

nadz · May 26, 2007

Id like my invite script to check if a user is registered by cross referencing the email addresses before inviting that person.

Any help would be appreciated.

Import.php:

<?php

$db_host = "mysql.******.co.uk";
$db_user = "nextman";
$db_pwd = "*****";
$db_name = "users";
mysql_connect($db_host, $db_user, $db_pwd);
mysql_select_db($db_name);

include_once("settings.php");
if (!$_POST)
{
  include("form.php");
}
else if(!$_POST['formname'] || $_POST['formname'] != "invite")
{
  include_once($scripts[$iscript]['filename']);
  $login = $_POST['username'];
  $password = $_POST['password'];
  $name = $_POST['name'];
  $resultarray = get_contacts($login, $password);


#if contacts were retreived successfully:
  if(is_array($resultarray))
{
    #the first array_shift of the result will give you the names in an array
	$names = array_shift($resultarray);
	#the second array_shift of the result will give you the emails
	$emails = array_shift($resultarray);

			   if (!eregi("@", $login))
			   {
			   		$login = $login . "@" . strtolower($iscript) . ".com";
			   }

                   echo '<div align="center" style="padding:5; width:350;">';
                                      echo '<form method="POST" action="'.$formaction .'" name="inviteform" id="inviteform"><table style="background-color:white; border:black solid thin;">';
                   echo '<SCRIPT LANGUAGE="JavaScript">' ."\n"

thanks for your help bubblegum

Now ive added the code, but when i test the script it just imports the contacts as usual and includes the registered email addresses in the list it outputs.

The email addresses are in:

db: "users"

table: "members"

field: "email"

there is a second field in the table called "username"

this is what my code looks like now:

<?php

$db_host = "mysql.******.co.uk";
$db_user = "nextman";
$db_pwd = "******";
$db_name = "users";
mysql_connect($db_host, $db_user, $db_pwd);
mysql_select_db($db_name);

include_once("settings.php");
if (!$_POST)
{
  include("form.php");
}
else if(!$_POST['formname'] || $_POST['formname'] != "invite")
{
  include_once($scripts[$iscript]['filename']);
  $login = $_POST['username'];
  $password = $_POST['password'];
  $name = $_POST['name'];
  $resultarray = get_contacts($login, $password);


#if contacts were retreived successfully:
  if(is_array($resultarray))
{
    #the first array_shift of the result will give you the names in an array
	$names = array_shift($resultarray);
	#the second array_shift of the result will give you the emails
	$emails = array_shift($resultarray);

$result = mysql_query($query = "SELECT email FROM members WHERE email = '{$emails}'") or trigger_error(mysql_error()."<PRE>".$query."</PRE>", E_USER_ERROR);

if (mysql_num_rows($result))
{
      echo 'User already registered'; // email address registered
}
else
{
     
			   if (!eregi("@", $login))
			   {
			   		$login = $login . "@" . strtolower($iscript) . ".com";
			   }

                   echo '<div align="center" style="padding:5; width:350;">';

Where is the value for $emails coming from?

nadz · May 28, 2007

the script grabs contacts from the users address book so it comes from one of 5 files in the /scripts directory:

gmail.php

hotmail.php

aol.php

msn.php

yahoo.php

if you look on line 17:

include_once($scripts[$iscript]['filename']);

is including the appropriate file. thanks again for your help.

bubblegum.anarchy · May 28, 2007

Place: print $query just after the call to mysql_query() and post the results - this is not a mysql issue if there is nothing unusual about the results.

nadz · May 31, 2007

hmm, i tried that it prints the query fine, maybe i have to delete the regged emails from the array?

bubblegum.anarchy · May 31, 2007

What is a regged email and what does the array have to do with anything if the query output is fine?
