Mentioned by -=InSaNe=- made by SkillMaster

Save as send_points.php

PHP Code


<?php

session_start();

include "config.php";

if($logged[username])

{

switch($_GET[page])

{

default:

echo ("

You have <b>$logged[points]</b> points in hand to send.<br>

<form method='post' action='?page=send'>

<select name='username'>");

$fetch = mysql_query("SELECT * FROM `members`");

while ($user = mysql_fetch_array($fetch))

{

echo ("<option value='$user[username]'>$user[username]</option>");

}

echo ("

</select><br>

<input type='text' name='points' size='20'>

<input type='submit' name='submit' value='Send'>");

break;



case 'send':

$username = strip_tags(htmlspecialchars($_POST[username]));

$points = strip_tags(htmlspecialchars($_POST[points]));

if ($logged[points] < $points)

{

echo ("You don't have that many points. <a href='send_points.php'>Back</a>");

}

elseif ($points == NULL)

{

echo ("Please enter a value of points. <a href='send_points.php'>Back</a>");

}

else

{

$fetch = mysql_query("SELECT * FROM `members` WHERE `username` = '$username'");

$user = mysql_fetch_array($fetch);



$points1 = $logged[points]-$points;

$points2 = $user[points]+$points;



$update1 = mysql_query("UPDATE `members` SET `points` = '$points1' WHERE `username` = '$logged[username]'");

$update2 = mysql_query("UPDATE `members` SET `points` = '$points2' WHERE `username` = '$username'");

echo ("You have sent $points to $username. <a href='send_points.php'>Back</a>");

}

break;

}

}

?>

Code

$fetch = mysql_query("SELECT * FROM `members`");
while ($user = mysql_fetch_array($fetch))
{
echo ("<option value='$user[username]'>$user[username]</option>");
}

Displays all of our users.

Code

<form method='post' action='?page=send'>
<select name='username'>");
$fetch = mysql_query("SELECT * FROM `members`");
while ($user = mysql_fetch_array($fetch))
{
echo ("<option value='$user[username]'>$user[username]</option>");
}
echo ("
</select><br>
<input type='text' name='points' size='20'>
<input type='submit' name='submit' value='Send'>");

Our form to define our variables.

Code

if ($logged[points] < $points)
{
echo ("You don't have that many points. <a href='send_points.php'>Back</a>");
}

if the users points is less than the points they are trying to send they get an error messge

Code

$points1 = $logged[points]-$points;
$points2 = $user[points]+$points;

$update1 = mysql_query("UPDATE `members` SET `points` = '$points1' WHERE `username` = '$logged[username]'");
$update2 = mysql_query("UPDATE `members` SET `points` = '$points2' WHERE `username` = '$username'");
echo ("You have sent $points to $username. <a href='send_points.php'>Back</a>");

Does out math and then updates the database gives us a success message.

That it.
Live earth on soon.
