Carterlake.org scripts with a few mods...

Tom at carterlake.org has done a great job generating and freely sharing his PHP scripts for other sites to use. I started my own journey with PHP programming by using his scripts (and Larry's at Anole Computer) as learning examples, and I can't thank them enough for their sharing! With Tom's permission (and some encouragement), I've set up this page to have links to the carterlake scripts that I've modified for various puposes. Most of the mods have to do with formatting for XHTML 1.0-Strict output (even when the source page was not).

advforecast.php (NOAA Forecast for all NWS areas)

Note: as of 12-Mar-2007, the Western Region website (www.wrh.noaa.gov) now offers the point-printable forecasts in the same format as the other regional websites, so this script now works for WRH, ERH, SRH and CRH websites.

Tom's advforecast.php script takes the point-printable forecast from NOAA for Western, Eastern, Southern and Central region NOAA websites, and converts to a set of icons/conditions/temperatures and text forecast for inclusion on your webpage. My mods add XHTML 1.0-Strict output and the ability to handle a redirection for county forecasts (offered by www.crh.noaa.gov) in case a point-printable forecast is not available. See these threads for the erh2crh version (http://www.wxforum.net/viewtopic.php?p=3768, and http://www.weather-watch.com/smf/index.php/topic,22504.0.html ) The latest version of this script also offers automatic failover to the Zone forecast if the point-printable forecast is not available. Set "$NOAAZone = 'ssZnnn';" in the code for your NOAA warning zone.

The script supports the ?force=1 parameter to reload the cache file, and also a ?force=2 to load the cache file from the backup County Zone forecast.

To use, you'll need an icon set uploaded in the /forecast/images directory on your website, and to set the $fileName variable inside the script to the URL for the point-printable forecast.

With V2.06 and up, the new parsing of the failover Zone forecast requires additional icons (available below) to be placed on your website.

The NOAA-NWS updated the icon set and provided a new dual-image icon to display 6-hour conditions for the 12-hour forecast icon. This icon is dynamically generated by a DualImage.php script (available below in the UPDATES file). With the DualImage.php script and associated icon templates installed, the V4.00+ version of advforecast2.php will support dynamic generation of dual images when needed. The script will fall-back to showing just the first 6-hour image if the DualImage.php is not available, OR if the meteotriviglio animated GIF images are used.

Sample included with:

<?php
$doIncludeNWS = true;
include("advforecast2.php"); ?>

You can also include it 'silently' and print just a few (or all) the contents where you'd like it on the page

<?php
$doPrintNWS = false;
require("advforecast2.php"); ?>

then on your page, the following code would display just the current and next time period forecast:

 <table>
<tr align="center" valign="top">
<?php print "<td>$forecasticons[0]</td><td>$forecasticons[1]</td>\n"; ?>
</tr>
<tr align="center" valign="top">

advisory.php (NOAA Advisory/Warning script)

This is a small mod to Tom's advisory script to eliminate some strange characters that began appearing just before the first line of the script output. This script is meant to be included in a webpage, not run as a separate page. (See the discussion at http://www.wxforum.net/viewtopic.php?t=539
