I sell a lot of egoods, or downloadable products that are anywhere from 5mb to 500mb. I wrote this script to display estimated download times so the customers had an idea of the time it would take to download a file. I don't know if anyone else could use it, but here it is.

First create the file download_time.php containing this code

Code:

<?
//calculate download times script 1-27-06 by Bill Brewer

//set initial variables
$filesize = $_GET['filesize'];
$s56k_speed = 50000;
$s128k_speed = 128000;
$s640k_speed = 640000;
$s1_2m_speed = 1200000;
$s1_8m_speed = 1800000;

// calculation script

//56k modem
$s56k_time = $filesize / $s56k_speed;
$s56k_hours = intval(intval($s56k_time) / 3600); 
$s56k_minutes = intval(($s56k_time / 60) % 60);

if ($s56k_hours == "0" && $s56k_minutes <= "01")
    {$s56k = "less than 1 minute";}
elseif ($s56k_hours == "0" && $s56k_minutes >= "01")
    { $s56k = "$s56k_minutes minutes";}
elseif ($s56k_hours >= "2" && $s56k_minutes >= "01")
    { $s56k = "$s56k_hours hours $s56k_minutes minutes";}
else {
    $s56k = "$s56k_hours hour $s56k_minutes minutes";}

//128k
$s128k_time = $filesize / $s128k_speed;
$s128k_hours = intval(intval($s128k_time) / 3600); 
$s128k_minutes = intval(($s128k_time / 60) % 60);

if ($s128k_hours == "0" && $s128k_minutes <= "01")
    { $s128k = "less than 1 minute";}
elseif ($s128k_hours == "0" && $s128k_minutes >= "01")
    { $s128k = "$s128k_minutes minutes";}
elseif ($s128k_hours >= "2" && $s128k_minutes >= "01")
    { $s128k = "$s128k_hours hours $s128k_minutes minutes";}
else {
    $s128k = "$s128k_hours hour $s128k_minutes minutes";}

// 640k
$s640k_time = $filesize / $s640k_speed;
$s640k_hours = intval(intval($s640k_time) / 3600); 
$s640k_minutes = intval(($s640k_time / 60) % 60);

if ($s640k_hours == "0" && $s640k_minutes <= "01")
    { $s640k = "less than 1 minute";}
elseif ($s640k_hours == "0" && $s640k_minutes >= "01")
    { $s640k = "$s640k_minutes minutes";}
elseif ($s640k_hours >= "2" && $s640k_minutes >= "01")
    { $s640k = "$s640k_hours hours $s640k_minutes minutes";}
else {
    $s640k = "$s640k_hours hour $s640k_minutes minutes";}

//1.2m
$s1_2m_time = $filesize / $s1_2m_speed;
$s1_2m_hours = intval(intval($s1_2m_time) / 3600); 
$s1_2m_minutes = intval(($s1_2m_time / 60) % 60);

if ($s1_2m_hours == "0" && $s1_2m_minutes <= "01")
    { $s1_2m = "less than 1 minute";}
elseif ($s1_2m_hours == "0" && $s1_2m_minutes >= "01")
    { $s1_2m = "$s1_2m_minutes minutes";}
elseif ($s1_2m_hours >= "2" && $s1_2m_minutes >= "01")
    { $s1_2m = "$s1_2m_hours hours $s1_2m_minutes minutes";}
else {
    $s1_2m = "$s1_2m_hours hour $s1_2m_minutes minutes";}

//1.8m
$s1_8m_time = $filesize / $s1_8m_speed;
$s1_8m_hours = intval(intval($s1_8m_time) / 3600); 
$s1_8m_minutes = intval(($s1_8m_time / 60) % 60);
if ($s1_8m_hours == "0" && $s1_8m_minutes <= "01")
    { $s1_8m = "less than 1 minute";}
elseif ($s1_8m_hours == "0" && $s1_8m_minutes >= "01")
    { $s1_8m = "$s1_8m_minutes minutes";}

    { $s1_8m = "$s1_8m_hours hours $s1_8m_minutes minutes";}
else {
    $s1_8m = "$s1_8m_hours hour $s1_8m_minutes minutes";}

This script is pretty simple, to use it just enter a url like this

Code:

www.yoursite.com/download_time.php?filesize=4928282

Just replace the filesize with the size of the file in bits. (You can use this site http://www.onlineconversion.com/computer_base2.htm to convert from larger sizes to bits.

I think the best way to do this is to add a link like this to the item description.

Code:

<A HREF="javascript:void(0)"
onclick="window.open('http://www.yoursite.com/download_time.php?filesize=83899283','downloadtime','width=550,height=250')">
Click here for estimated download times</A>

This will create a popup window displaying the download times.
