I am trying to implement an invitation only registration system for a small business website.Where the administrator can type in an employee’s personal email and have a verification code sent to him/her.
When the employee clicks on the link in the email he will be redirected to the registration page. (used switch to determine what shows)
The thing is I made the registration page earlier on and I am having trouble implementing it to this invitation code. The invitation code uses “echo” to display text while the original registration page has a form within a table created using php, html, and css. My question is how can I modify the code so that they are compatible.
Please see below for the code:
INVITE.php
mysql_select_db($database_connSQL, $connSQL);
$query_RecInvite = "SELECT * FROM invite_codes";
$RecInvite = mysql_query($query_RecInvite, $connSQL) or die(mysql_error());
$row_RecInvite = mysql_fetch_assoc($RecInvite);
$totalRows_RecInvite = mysql_num_rows($RecInvite);
/*
This script assumes you already have a database setup, with a connection string in place.
First, we'll need to create our table...
Copy/paste the following SQL code into the database you'll be using.
CREATE TABLE `invite_codes` (
`id` int(11) NOT NULL auto_increment,
`invite_code` varchar(35) NOT NULL default '',
`time_stored` int(11) NOT NULL default '0',
PRIMARY KEY (`id`)
) TYPE=MyISAM ;

On your registration page, pull the invitation code from the query string (
site.php?code=ajiofdjasoiej39048). Then, check if a row exists in the database with that invitation code. If it does, then display the registration form. Otherwise display an error message. Check the code again on submission, and after the user is registered successfully, delete the invite code from the DB.Also, php_mysql is deprecated. Please use MySQLi or PDO instead.
