So basically I have a site, and on that site, I have a page that submits a form and updates a database. I have it set up so that someone can enter in Multiple values into a textarea, one on each line, and it will submit each of those values as a new row in the database, but for the life of me, I cannot figure out how to check those values against the actual users.
It is basically a point system, where the staff can award points users of the site. But at the moment, a Staff member could enter in Jibberish, and it would insert that into the database, but I want it to check my users table to make sure the user exists before it inserts it into the database.
here is my code:
[php]<?php
include ‘global.php’;
echo $headersidebar;
if ($_COOKIE[‘access’] == $accessstaff)
{
if(count($_POST))
{
$array = preg_split(’/(\r?\n)+/’, $_POST[‘studentname’]);
foreach($array as $students)
{
$statusmsg = ‘You have successfully submitted points to the database.’;
mysql_query(“INSERT INTO points (giver, receiver, points, category, reason, date, status) VALUES (’{$_COOKIE[‘username’]}’, ‘{$students}’, ‘{$_POST[‘pointamt’]}’, ‘{$_POST[‘pointcat’]}’, ‘{$_POST[‘pointreason’]}’, ‘{$date}’, ‘Validating’)”);
}
}
$addpointspage = $statusmsg . ’
<form action="submit_points.php" method="post">
<table class="table" >
<tr>
<td colspan="10">
<h1><strong><center>Submit Points</center></strong></h1>
</td>
</tr>
<tr>
<td colspan="10" rowspan="100">

</td>

}
elseif (1==1)
{
$addpointspage = $accessdenied;
}
echo ’

’ . $addpointslink . ’
<div style="clear: both;"> </div>
</div>
<!-- end page -->
echo $footer;
?>[/php]
I am fairly new to PHP, so I would appreciate any help someone could give me; I am not too good with arrays and such, so this one has got me stumped.
