Some weather programs do not have yesterday weather values and also have no built in scheduled tasks. In our case we have to find a solution for WSWIN, WVIEW and Weatherlink.com
Because we need those yesterday values we run a smal script on our webserver at 23:50 (11:50 PM) to copy the min max values of today into a file which will be used shrotly (after 24:00) as yesterdays values.The script which must be run is: yesterday.php
If you already have set a password in your settings, do no forget to add ?pw=yourpassword to the link.
The yesterday script is password protected to make sure that others are not playing jokes on you by running the yesterday script at other times then the intended time.
So we need a cronjob which runs every day at 23:50 to call
in a browser. The xxxxxx should be replaced with your password as set in wsUserSettings.php. If you did not set it yet, you can omit it.
The number of regions to retrieve weather warnings from is "unlimited" when using Curly-scrips. The response time becomes unacceptable when using to much areas.
Here you find the readme Curly wrote: www.yourwebsite.com/weather28/usa/nws-alerts/NWS-alerts_read_me.html
We need a cron-jon to retrieve the weather warnings so that visitors do not have to wait for that.
The script which must be run is: www.yourwebsite.com/weather28/cron_job.php
This cronjob should run every 5 - 15 minutes and call our script www.yourwebsite.com/weather28/cron_job.php in a browser
Most WVIEW users could use the cron faciliteits of their Linux system they are runnig WVIEW on.
