Aweber does tno allow cron job - php

Question

I can access this script directly via URL and it works fine but as a cron job ot doesnt work. Is it aweber or am I doing something wrong?
Awebre's documentation is one of the worst ones I have ever come across!
I am not sure why there is no explanation of this in their docs!
Thanks

Answer 1

Looks like a few places where this could be failing:
1) You have relative paths in your includes. The cron may not be able to find the included files. Try changing these to full paths.
2) Your code requires a browser environment (setting cookies, http header Location etc). None of this will work outside of a browser.
You should always execute the file from the command line as the user the cron runs as to test it. Any errors will be obvious.
To fix your issue you should use this tutorial which uses the browser to setup the credentials. After that it can be run from the command line/cron:

Answer 2

Try using this in the cron command:
wget -qO- http://yoururlhere/ &> /dev/null
It's not the best solution since "self calls" aren't recommended, but it'll keep you from dealing with environment settings.
