Mass value change for cron use

Recommended Posts

I've set up my cron to run my php file every hour, but at the moment that file is blank because I'm unsure how to go about it.

In my database I have 3 fields, [[b]Progress[/b]],[[b]maxprogress[/b]] and [[b]work[/b]].

I need a script that does the following:

update [[b]progress[/b]] by 10% of the [[b]maxprogress[/b]], [i]or 15% increase if [[b]work[/b]] = 1[/i]

ensuring that [[b]progress[/b]] does not exceed [[b]maxprogress[/b]]



Hope that wasn't too complicated to understand - anyone know how I can go about this?

This should work:

[code]<?php

$query = mysql_query( "select * from table" );

while( $row = mysql_fetch_array( $query ) )
{
if( $row[work] == 1 ? $work = 15 : $work = 10 );

$new = ( ( 100 / $row[maxprogress] ) * $work ) + $row[progress];

if( $new > $row[maxprogress] ? $new = $row[maxprogress] : $new = $new );

mysql_query( "update table set progress = '$new' where id = '$row[id]'" );
}

?>[/code]
